Okay, let’s get real: case studies can be kinda snooze-worthy. But guess what? They don’t have to be!

What is a case study presentation?

What is the purpose of presenting a case study, how to structure a case study presentation, how long should a case study presentation be, 5 case study presentation examples with templates, 6 tips for delivering an effective case study presentation, 5 common mistakes to avoid in a case study presentation, how to present a case study faqs.

A case study presentation involves a comprehensive examination of a specific subject, which could range from an individual, group, location, event, organization or phenomenon.

They’re like puzzles you get to solve with the audience, all while making you think outside the box.

Unlike a basic report or whitepaper, the purpose of a case study presentation is to stimulate critical thinking among the viewers. 

The primary objective of a case study is to provide an extensive and profound comprehension of the chosen topic. You don’t just throw numbers at your audience. You use examples and real-life cases to make you think and see things from different angles.

The primary purpose of presenting a case study is to offer a comprehensive, evidence-based argument that informs, persuades and engages your audience.

Here’s the juicy part: presenting that case study can be your secret weapon. Whether you’re pitching a groundbreaking idea to a room full of suits or trying to impress your professor with your A-game, a well-crafted case study can be the magic dust that sprinkles brilliance over your words.

Think of it like digging into a puzzle you can’t quite crack . A case study lets you explore every piece, turn it over and see how it fits together. This close-up look helps you understand the whole picture, not just a blurry snapshot.

It’s also your chance to showcase how you analyze things, step by step, until you reach a conclusion. It’s all about being open and honest about how you got there.

Besides, presenting a case study gives you an opportunity to connect data and real-world scenarios in a compelling narrative. It helps to make your argument more relatable and accessible, increasing its impact on your audience.

One of the contexts where case studies can be very helpful is during the job interview. In some job interviews, you as candidates may be asked to present a case study as part of the selection process.

Having a case study presentation prepared allows the candidate to demonstrate their ability to understand complex issues, formulate strategies and communicate their ideas effectively.

The way you present a case study can make all the difference in how it’s received. A well-structured presentation not only holds the attention of your audience but also ensures that your key points are communicated clearly and effectively.

In this section, let’s go through the key steps that’ll help you structure your case study presentation for maximum impact.

Let’s get into it. 

Open with an introductory overview 

Start by introducing the subject of your case study and its relevance. Explain why this case study is important and who would benefit from the insights gained. This is your opportunity to grab your audience’s attention.

Explain the problem in question

Dive into the problem or challenge that the case study focuses on. Provide enough background information for the audience to understand the issue. If possible, quantify the problem using data or metrics to show the magnitude or severity.

Detail the solutions to solve the problem

After outlining the problem, describe the steps taken to find a solution. This could include the methodology, any experiments or tests performed and the options that were considered. Make sure to elaborate on why the final solution was chosen over the others.

Key stakeholders Involved

Talk about the individuals, groups or organizations that were directly impacted by or involved in the problem and its solution. 

Stakeholders may experience a range of outcomes—some may benefit, while others could face setbacks.

For example, in a business transformation case study, employees could face job relocations or changes in work culture, while shareholders might be looking at potential gains or losses.

Discuss the key results & outcomes

Discuss the results of implementing the solution. Use data and metrics to back up your statements. Did the solution meet its objectives? What impact did it have on the stakeholders? Be honest about any setbacks or areas for improvement as well.

Include visuals to support your analysis

Visual aids can be incredibly effective in helping your audience grasp complex issues. Utilize charts, graphs, images or video clips to supplement your points. Make sure to explain each visual and how it contributes to your overall argument.

Pie charts illustrate the proportion of different components within a whole, useful for visualizing market share, budget allocation or user demographics.

This is particularly useful especially if you’re displaying survey results in your case study presentation.

Stacked charts on the other hand are perfect for visualizing composition and trends. This is great for analyzing things like customer demographics, product breakdowns or budget allocation in your case study.

Consider this example of a stacked bar chart template. It provides a straightforward summary of the top-selling cake flavors across various locations, offering a quick and comprehensive view of the data.

Recommendations and next steps

Wrap up by providing recommendations based on the case study findings. Outline the next steps that stakeholders should take to either expand on the success of the project or address any remaining challenges.

Acknowledgments and references

Thank the people who contributed to the case study and helped in the problem-solving process. Cite any external resources, reports or data sets that contributed to your analysis.

Feedback & Q&A session

Open the floor for questions and feedback from your audience. This allows for further discussion and can provide additional insights that may not have been considered previously.

Closing remarks

Conclude the presentation by summarizing the key points and emphasizing the takeaways. Thank your audience for their time and participation and express your willingness to engage in further discussions or collaborations on the subject.

Well, the length of a case study presentation can vary depending on the complexity of the topic and the needs of your audience. However, a typical business or academic presentation often lasts between 15 to 30 minutes. 

This time frame usually allows for a thorough explanation of the case while maintaining audience engagement. However, always consider leaving a few minutes at the end for a Q&A session to address any questions or clarify points made during the presentation.

When it comes to presenting a compelling case study, having a well-structured template can be a game-changer. 

It helps you organize your thoughts, data and findings in a coherent and visually pleasing manner. 

Not all case studies are created equal and different scenarios require distinct approaches for maximum impact. 

To save you time and effort, I have curated a list of 5 versatile case study presentation templates, each designed for specific needs and audiences. 

Here are some best case study presentation examples that showcase effective strategies for engaging your audience and conveying complex information clearly.

• Know your audience : Tailor your presentation to the knowledge level and interests of your audience. Remember to use language and examples that resonate with them.
• Rehearse : Rehearsing your case study presentation is the key to a smooth delivery and for ensuring that you stay within the allotted time. Practice helps you fine-tune your pacing, hone your speaking skills with good word pronunciations and become comfortable with the material, leading to a more confident, conversational and effective presentation.
• Start strong : Open with a compelling introduction that grabs your audience’s attention. You might want to use an interesting statistic, a provocative question or a brief story that sets the stage for your case study.
• Be clear and concise : Avoid jargon and overly complex sentences. Get to the point quickly and stay focused on your objectives.
• Use visual aids : Incorporate slides with graphics, charts or videos to supplement your verbal presentation. Make sure they are easy to read and understand.

Nailed your case study, but want to make your presentation even stronger? Avoid these common mistakes to ensure your audience gets the most out of it:

Overloading with information

A case study is not an encyclopedia. Overloading your presentation with excessive data, text or jargon can make it cumbersome and difficult for the audience to digest the key points. Stick to what’s essential and impactful. Need help making your data clear and impactful? Our data presentation templates can help! Find clear and engaging visuals to showcase your findings.

Lack of structure

Jumping haphazardly between points or topics can confuse your audience. A well-structured presentation, with a logical flow from introduction to conclusion, is crucial for effective communication.

Ignoring the audience

Different audiences have different needs and levels of understanding. Failing to adapt your presentation to your audience can result in a disconnect and a less impactful presentation.

Poor visual elements

While content is king, poor design or lack of visual elements can make your case study dull or hard to follow. Make sure you use high-quality images, graphs and other visual aids to support your narrative.

Not focusing on results

A case study aims to showcase a problem and its solution, but what most people care about are the results. Failing to highlight or adequately explain the outcomes can make your presentation fall flat.

How to start a case study presentation?

Starting a case study presentation effectively involves a few key steps:

• Grab attention : Open with a hook—an intriguing statistic, a provocative question or a compelling visual—to engage your audience from the get-go.
• Set the stage : Briefly introduce the subject, context and relevance of the case study to give your audience an idea of what to expect.
• Outline objectives : Clearly state what the case study aims to achieve. Are you solving a problem, proving a point or showcasing a success?
• Agenda : Give a quick outline of the key sections or topics you’ll cover to help the audience follow along.
• Set expectations : Let your audience know what you want them to take away from the presentation, whether it’s knowledge, inspiration or a call to action.

How to present a case study on PowerPoint and on Google Slides?

Presenting a case study on PowerPoint and Google Slides involves a structured approach for clarity and impact using presentation slides :

• Title slide : Start with a title slide that includes the name of the case study, your name and any relevant institutional affiliations.
• Introduction : Follow with a slide that outlines the problem or situation your case study addresses. Include a hook to engage the audience.
• Objectives : Clearly state the goals of the case study in a dedicated slide.
• Findings : Use charts, graphs and bullet points to present your findings succinctly.
• Analysis : Discuss what the findings mean, drawing on supporting data or secondary research as necessary.
• Conclusion : Summarize key takeaways and results.
• Q&A : End with a slide inviting questions from the audience.

What’s the role of analysis in a case study presentation?

The role of analysis in a case study presentation is to interpret the data and findings, providing context and meaning to them. 

It helps your audience understand the implications of the case study, connects the dots between the problem and the solution and may offer recommendations for future action.

Is it important to include real data and results in the presentation?

Yes, including real data and results in a case study presentation is crucial to show experience,  credibility and impact. Authentic data lends weight to your findings and conclusions, enabling the audience to trust your analysis and take your recommendations more seriously

How do I conclude a case study presentation effectively?

To conclude a case study presentation effectively, summarize the key findings, insights and recommendations in a clear and concise manner. 

End with a strong call-to-action or a thought-provoking question to leave a lasting impression on your audience.

What’s the best way to showcase data in a case study presentation ?

A Guide for Case Study Interview Presentations

You’ve been called for an interview at your dream firm and spent the entire night rote learning policies, laws, and theories to impress the panel of interviewers with your ability to retain knowledge. However, when the interview presentation begins, contrary to your expectations of being asked to recall the information you’ve memorized, you are handed a piece of paper, which entails details about a financial embezzlement scandal. You are instructed to analyze the document and provide solutions to the problems mentioned at the end of the document.

The above-mentioned hypothetical situation is an example of a case study interview, often used by professional services firms to assess and hire applicants.

Table of Contents

What is a case study interview?

Why a case study interview, format of a case study interview, non-profitability cases, startup and early stage ventures, market sizing framework, profitability framework, market study framework, merger & acquisition cases framework.

• Example Scenario 1

Example Scenario 2

A case study interview is one in which the candidate is interviewed about a scenario-based business organizational challenge that the company may have experienced. The case interview allows candidates interested in a career in consulting to exhibit their analytical, communication, and reasoning abilities. The case study interviews are constructed in such a way that they aid in identifying key issues in order to develop effective solutions. ( LSE )

To gauge a potential employee’s ability to apply theoretical knowledge to real-world situations and develop workable answers in a constrained amount of time, interviewers use the case study interview method. Big market players, like McKinsey, Deloitte, or Bain and company, use case studies in their job interviews . The interviewer may measure a candidate’s ability not just to grasp technical elements of a real-life problem, but also to come up with creative solutions, by asking case study questions.

Case study interviews are often carried out in one of two ways, depending on the goals and specifications of the company conducting the interview.

• Interviewer-led interview
• Candidate led Interview

Interviewer led

During a case study interview, the interviewer is the one who sets the tone, pace, and overall structure. It is a highly structured interview where the candidate should be prepared for a sudden change of style depending on the interviewer. The interviewer continues asking questions they’ve already prepared regardless of the candidate’s answers.

Candidate led

In contrast to an interviewer-led, a candidate-led is less regimented, and the candidate takes the wheel. They are expected to shape the Interview from start to finish. In this case, the candidate’s answers determine the line of questions. It is convenient for a firm to assess if an individual can handle situations independently by conducting a candidate-led interview.

In the final section, we’ve provided candidate- and interviewer-led interview cases in our examples.

Archetypes of Case Study Interviews

Not every case study interview is centered on profit or revenue-generating scenarios. The interviewer may begin with a case of Non-Profitability. The analyzed organization might face a challenge to reach an objective. It requires a situation analysis in order to provide a diagnosis. The candidate will run the analysis, provide a diagnosis, and based on it will define a strategy to overcome the challenge and reach the objective. 

During the case interview, the focus is on strategic issues and recommendations for developing an industry’s environment while dealing with challenges. Regulations, consumer preferences, and more might all fall under this umbrella. Here, a SWOT analysis is useful in identifying the competitive landscape.

Taking into account the emerging Industrial Revolution 4.0 startup boom. The interviewer will most likely use this as an example in your case study interview. Market entry cases are comparable to startup, and early venture case studies, except the company, is smaller and employs fewer people. One must have a strong product or service in order to have a foothold in the market with significant profit margins.

The case study discussion should focus on the following three areas: the right people, the right problem, and the right solution. A minimum viable product and a well-thought-out business strategy are necessary. Startups are more likely to be agile and successful when these three characteristics are present.

In a market sizing question, commonly known as ‘guesstimate,’ the candidate is asked to estimate the size of a market randomly selected by the interviewer with little or no data available. Market size questions should be approached by segmenting data and adapting the MECE technique. In a case study interview, you may also solve market sizing problems by using the issue decision tree .

 Case study interview questions can be the following:

• Estimate the market size of frozen foods in a suburban area of Melbourne.
• How many individuals are currently consuming vitamin water in China?

Every firm’s ultimate goal is to earn profits; therefore, the profitability framework seeks to identify whether the candidate can correctly assess the cause of decreased profitability or ways of increasing profitability. Candidates are usually provided with names, figures, and facts to answer questions pertaining to different aspects of profitability.

A market study framework generally aids in determining an individual’s ability to assess market factors like market entry potential, revenue growth, and market share.

In order to construct a framework for a market study in a case interview, the candidate must focus on five components. The market, rivals, customers, your firm, and your product/service are all included. This market analysis methodology necessitates the candidate to ask further clarifying questions on the financial and profitability impact on the company in discussion.

The merger and acquisition cases framework is considered one of the most accurate judges of the candidate’s potential as it deals with all major components of market analysis, including but not limited to market sizing, profitability, and market study factors. These case study interview questions usually deal with whether or not two or more companies should opt for a merger/acquisition.

When addressing an M&A case, three components should be taken into account: the synergies between the two organizations, the integration of talent, technology, and so on, and regulatory approvals.

Case Study Interview Example Scenario 1

Objective: Country X is situated in Asia and has a population of 20 million. It is developing a national action plan to transform its education system. It wants to improve the quality and quantity of children’s education. The objective is to advise the client on transforming their education system.

Description: Country X is a developing nation of 20 million residents and has emerged as a free market economy after spending decades under communism. The Country aspires to have an economic action plan for transforming education. The schooling system in Country X is completely public (state managed) and has government-run schools spread throughout the Country. Children are admitted from age 5 to 18. The objective is to evaluate the current state of the education system and how it can meet the aspirations of the Government. 

This type of scenario mostly follows an interviewer-led approach. This falls under the Non-Profitability case study example. The primary purpose is to examine the issue from the top-down approach to get a higher-level view. Initially, qualitative analysis is performed.

• The interviewer will first ask how you intend to analyze and evaluate the problem’s underlying issues.

An approach is to structure the response into three sections. A PowerPoint slide with a clear bifurcation of these three sections can be presented under a separate heading.

The initial section should emphasize some quantitative metrics of education. This encompasses observations such as how age, gender, and geography affect access to education. How many teachers are working in schools around the region? How much is spent on healthcare?

The second component is the quality of education, including the curriculum, teaching methods, etc. The second question is quantitative and requires analysis of a table containing distinct informational values relative to competitor nations.

A third element of the analysis could be to understand the effect of education in Country X’s economics objectives.

You will be provided with a table with figures for the number of pupils and teachers, health care expenditure, student-to-teacher ratio, etc. You will be expected to evaluate competitor values in comparison to Country X. Among the observations that can be made are how Country X compared to other nations regarding health care spending and the student-to-teacher ratio. The table values can be interpreted as, e.g., Country X has the highest education expenditure but has the lowest student-to-pupil ratios. All this information can be presented using SlideModel PowerPoint templates .

Comparing the observation to international standards is another way of acquiring a deeper understanding of the provided data. Because only 15 percent of Country X’s population is enrolled in school, the question is how many schools should be opened given that Country Y surpasses Country X in an international comparison. To solve such a puzzle, you will use comparable data to compute the number of schools utilizing population and school information from the provided data. This will assist you in determining a solid number to present in the Interview. The final number can be presented as a percentage or an absolute number in a much larger font on the ppt slide. SlideModel has a variety of case study templates you can choose from to showcase your result in a much more engaging manner.

These two approaches for the qualitative and quantitative aspects of the case Interview enable us to cover the fundamentals of a case study interview. 

Objective: Client Y is about to launch a new phone and desires to determine the size of the Apple product market. The objective is to determine how many iPhones Apple sells in the United States annually.

Description: Client X seeks an analysis of the current market size of the iPhone, its primary rival in the mobile phone industry. The current population of the United States is 320 million, and iPhone has a very large client base in the Country. The client requests that you calculate a number that provides a reliable estimate of the size of the iPhone market in the United States.

We will use a Three-step technique for a market size example to tackle this problem.

Step 1: Formulate the right question

To define market size, asking appropriate clarifying questions is a must. It is useful to define what the market size is and how to give a proper estimate for the market segment based on the given information.

For example:

Are we concentrating on a single iPhone model or the entire lineup?

Is it simply applicable to the United States, or do we also need to estimate worldwide iPhone sales through the US outlet?

After asking the appropriate clarifying questions, you can formulate a coherent strategy.

Step 2: Building a Framework

There are two sorts of problem-solving strategies for gauging the market questions. The top-down method and the bottom-up method.

The appropriate and easy way to solve this is to utilize top-down methodology and show it via an Issue tree. Using the MECE (Mutually conclusive and Collectively exhaustive) technique , an issue tree is a logical tree that may be depicted graphically to address difficult business challenges. It is quite common in market size questions. On the SlideModel website, you will discover a choice of templates for creating an excellent visual tool, i.e., The Issue/Logic tree.

You might convey it by beginning with the United States 320 million people.

Determine what proportion of phones are iPhones.

Identifying the frequency with which an individual purchases an iPhone each year.

And determine the number of iPhones sold based on the frequency and quantity of iPhone owners.

Step 3: Estimating and making assumptions

The estimated population of the United States is 320 million. Assuming that 75 percent of the United States population possesses a mobile phone and 30% are iPhone users because the number of smartphone users has multiplied in the digital era, we obtain: 

75 % x 320 million = 240 million Mobile Phone users.

30 % x 240 million = 72 million iPhone users.

Again, we suppose that each of these 72 million people buys an iPhone every two years. A single client will acquire one iPhone 0.5 times in a year.

Therefore, 0.5 times 72 million is 36 million iPhone sales.

To estimate the size of the iPhone market in the United States, we might assume the average iPhone price is $100.

By calculating the cost by the number of units sold a year, we get:

$100 x 36,000,000 = $3.6 billion USD.

Therefore, the annual market size for apple goods is $3.6 billion.

Calculations and estimations utilizing the said frameworks require practice and findings. SlideModel will assist you in organizing your framework and offer you visual tools to successfully convey your findings to the interviewer.

This is all about highlighting the benefits. Paint a vivid picture of the transformative results achieved using your solution.

Use compelling data and emotive testimonials to amplify the desire for similar outcomes, therefore boosting your audience's motivation.

This refers to making the desired action easy to perform. Show how straightforward it is to implement your solution.

Use clear language, break down complex ideas, and reinforce the message that success is not just possible, but also readily achievable with your offering.

This is your powerful call-to-action (CTA), the spark that nudges your audience to take the next step. Ensure your CTA is clear, direct, and tied into the compelling narrative you've built.

It should leave your audience with no doubt about what to do next and why they should do it.

Here’s how you can do it with Storydoc:

How to adapt your presentation for your specific audience?

Every audience is different, and a successful case study presentation speaks directly to its audience's needs, concerns, and desires.

Understanding your audience is crucial. This involves researching their pain points, their industry jargon, their ambitions, and their fears.

Then, tailor your presentation accordingly. Highlight how your solution addresses their specific problems. Use language and examples they're familiar with. Show them how your product or service can help them reach their goals.

A case study presentation that's tailor-made for its audience is not just a presentation—it's a conversation that resonates, engages, and convinces.

How to design a great case study presentation?

A powerful case study presentation is not only about the story you weave—it's about the visual journey you create.

Let's navigate through the design strategies that can transform your case study presentation into a gripping narrative.

Add interactive elements

Static design has long been the traditional route for case study presentations—linear, unchanging, a one-size-fits-all solution.

However, this has been a losing approach for a while now. Static content is killing engagement, but interactive design will bring it back to life.

It invites your audience into an evolving, immersive experience, transforming them from passive onlookers into active participants.

Which of these presentations would you prefer to read?

Use narrated content design (scrollytelling)

Scrollytelling combines the best of scrolling and storytelling. This innovative approach offers an interactive narrated journey controlled with a simple scroll.

It lets you break down complex content into manageable chunks and empowers your audience to control their reading pace.

To make this content experience available to everyone, our founder, Itai Amoza, collaborated with visualization scientist Prof. Steven Franconeri to incorporate scrollytelling into Storydoc.

This collaboration led to specialized storytelling slides that simplify content and enhance engagement (which you can find and use in Storydoc).

Here’s an example of Storydoc scrollytelling:

Bring your case study to life with multimedia

Multimedia brings a dynamic dimension to your presentation. Video testimonials lend authenticity and human connection. Podcast interviews add depth and diversity, while live graphs offer a visually captivating way to represent data.

Each media type contributes to a richer, more immersive narrative that keeps your audience engaged from beginning to end.

Prioritize mobile-friendly design

In an increasingly mobile world, design must adapt. Avoid traditional, non-responsive formats like PPT, PDF, and Word.

Opt for a mobile-optimized design that guarantees your presentation is always at its best, regardless of the device.

As a significant chunk of case studies are opened on mobile, this ensures wider accessibility and improved user experience , demonstrating respect for your audience's viewing preferences.

Here’s what a traditional static presentation looks like as opposed to a responsive deck:

Streamline the design process

Creating a case study presentation usually involves wrestling with an AI website builder .

It's a dance that often needs several partners - designers to make it look good, developers to make it work smoothly, and plenty of time to bring it all together.

Building, changing, and personalizing your case study can feel like you're climbing a mountain when all you need is to cross a hill.

By switching to Storydoc’s interactive case study creator , you won’t need a tech guru or a design whizz, just your own creativity.

You’ll be able to create a customized, interactive presentation for tailored use in sales prospecting or wherever you need it without the headache of mobilizing your entire team.

Storydoc will automatically adjust any change to your presentation layout, so you can’t break the design even if you tried.

A case study interview isn’t your average interview. While most interviews ask you to give examples of how you use your skills on the job, in a case study interview, you’ll use those skills in front of the interviewer to solve a real-life problem.

It’s like auditioning for the school play. But instead of showing you can sing and dance, you’re using a case interview to show how you provide innovative solutions to pressing business problems. Not sure how to get ready for this kind of interview? We’ve got you covered. This guide explains how to prep for a case study interview.

Case studies are used across a variety of industries — everything from business to medicine. They are an in-depth examination, analysis, and critique of a real-world scenario the company experienced. People discuss the situation and explore what they learned while forming new solutions to try when they face a similar situation in the future and hope to improve their performance.

For example, doctors and nurses use case studies to improve how they diagnose and treat patients. Using real patient information, the medical team analyzes the case to see what the team may have missed and why they missed it. Learning from these errors helps the team better prepare for similar cases in the future to improve patient care.

While many industries use case studies to iterate and improve their performance, not every company uses case study interviews. This type of interview is very common at consulting companies (no matter what kind of consulting it is). But it’s not unusual for companies outside of consulting to use case interviews for marketing or operations roles.

In a case study interview, you’re given a real-world situation the company has faced and are tasked with analyzing it and suggesting a course of action.

Avg. Time: 5-6 hours

Skills you’ll build: Prioritizing, planning, data analysis, error spotting, communication, strategic thinking

Businesses use case study interviews to assess your abilities in real-time. While you’ll probably draw on a variety of skills, most case study interviews assess:

• Strategic thinking
• Analytical skills
• Common sense

The advantage of a case study interview is that the interviewer can evaluate your ability in each of these areas and see how you’ll actually use them on the job.

What Is a Fit Interview?

Some people use “case study interview” and “fit interview” interchangeably. While a fit interview and a case study interview both ask behavioral interview questions , they are not the same thing.

A case study interview assesses your ability to do the job. It primarily evaluates how you approach business problems and use your skills to solve them. A fit interview is about company culture fit. The interviewer asks questions that assess how well you’ll fit into the company, like asking you questions about what motivates you or how you lead .

Fit and case interviews are important parts of the evaluation process. Getting the job done is just as critical as getting along with coworkers and supporting the company’s mission. Depending on where you interview, you may have one fit interview and one case study interview, or the fit interview may be a smaller part of the case study interview.

What You’ll Learn in a Case Study Interview

A case study interview allows the hiring manager to see your skills in action and how you approach business challenges. But it also teaches you a lot about the company (even if you’re doing most of the talking).

In a sense, you’re behaving as an employee during a case study interview. This gives you a peek behind the curtain, allowing you to see the company’s inner workings, like how they approach business problems and what they expect from you and your performance.

For example, you may offer a novel approach to solving a problem during a case interview. How does the interviewer react to it? Are they impressed? Surprised? Is there a scowl or frown on their face? Their reaction gives you insights into how the company will likely receive your solutions.

Skills you’ll build: Critical thinking, creativity, brainstorming

Depending on the specific company, you may have the case study interview questions in advance, but you may not. Whether you do or don’t, here’s how to prepare for a case study interview.

Conduct Deep Research

Good interview prep for any interview means researching the company. That includes things like learning more about the company’s mission and the challenges the industry faces. But when you’re preparing for a case study interview, your research needs to go deeper. 

When you answer a case study question, your answer has to be specific to the company’s clients or business objectives. For example, if you’re interviewing for a role in strategy consulting , your answer shouldn’t focus on aspects of human resources consulting (unless it’s particularly relevant).

Your research needs to include the kinds of clients the company works with and what types of problems the company solves. For example, the company may only consult for Fortune 100 companies that need accounting advice. Keep these facts in mind as you prepare for the interview.

Case Study Interview Formats

There are four types of case study interview formats:

• Candidate-led: The interviewer asks you a specific question (or gives you a prompt), and you walk the interviewer through a detailed answer.
• Employer-led: The interviewer leads you through a series of specific (and predetermined) prompts and questions, no matter your answers.
• Presentation: You’re given a problem in advance to create and present a detailed case study.
• Video: Similar to a presentation case study interview, you’ll create a video presentation of the case study.

Most companies will tell you in advance which style of case study interview you should prepare for. But if they don’t, reach out to your recruiter or check the company’s website. Many include the essential details you need to prepare for the case study interview.

Seek Out Company-Specific Tips

Speaking of companies and their websites, not only do many companies that use case study interviews tell you the format, they often include helpful tips and tricks to help candidates prepare. This includes what to expect, what the company is looking for skill-wise, and what kinds of responses they want. They may even have a few practice questions and videos you can use to help you prep.

Unlike other common interview questions , it’s not as easy to prepare an answer to case study interview questions. Even though you know it’s a case study interview, you don’t necessarily know the specifics of the case or what problems you’ll be asked to solve.

Cybersecurity

Work through a case experience in this free course from PwC Switzerland. Create a pitch, conduct a risk assessment, and explain your findings.

Skills you’ll build: Risk management frameworks, cause analysis, risk impact assessment, system security

That said, it’s likely your case study interview questions will cover one or several of these concepts:

• Entering new markets
• Increasing profits
• Cutting costs
• Turnarounds
• Mergers and acquisitions
• Pricing strategy
• Developing new products
• Industry analysis
• Competitive response

While there are many ways to answer case study interview questions, a few basic prep tips can help you get ready for every question.

In addition to what you usually bring to a job interview , make sure you bring a notepad and pen or pencil to a case study interview. Taking notes will help you better understand the questions and formulate your answers. It also gives you a place to calculate numbers and figures if you need to. Not every case study interview allows calculators, so you’ll need to be ready to do your calculations manually.

Ask Specific Questions

As you’re working through the case study, you can and should ask any clarifying questions you need. The interviewer wants to hear specific, detailed answers that solve the problem. So, whenever you’re unclear, ask a follow-up question to not only get what you need but to give the interviewer what they need. 

That said, your question(s) should be very specific. You need to verify exactly what the interview is asking so you can create an appropriate answer. Say the interviewer gives you a broad question: The client’s revenue is falling. How do you help them increase it? You can follow up with a very specific question or two to make sure you understand what the interviewer is asking:

You’re asking how I would help the client raise revenue, correct? Are you also asking how I would help them increase their profit and cut costs?

Talk Them Through It

A big part of the case study interview is seeing you in action. However, in this case, “see” really means “how you think.” Since the interviewer can’t hear your inner monologue, you’ll need to practice thinking out loud.

While the interviewer wants to hear your solution, they also want to hear how you got there. That means talking through your entire thought process. Instead of saying, “I’d do X,” you have to explain how you arrived at your decision while you’re getting there.

Because not everyone thinks out loud, it may feel unnatural to you, and you likely won’t be expected to do it on the job. But it’s crucial to practice this skill — and it is a skill — because the interviewer is expecting you to do it in a case study interview.

1. The key to landing your consulting job.

Case interviews - where you are asked to solve a business case study under scrutiny - are the core of the selection process right across McKinsey, Bain and BCG (the “MBB” firms). This interview format is also used pretty much universally across other high-end consultancies; including LEK, Kearney, Oliver Wyman and the consulting wings of the “Big Four”.

If you want to land a job at any of these firms, you will have to ace multiple case interviews.

It is increasingly likely that you will also have to solve online cases given by chatbots. You might need to pass these either before making it to interview or be asked to sit them alongside first round interviews.

Importantly, case studies aren’t something you can just wing . Firms explicitly expect you to have thoroughly prepared and many of your competitors on interview day will have been prepping for months.

Don’t worry though - MCC is here to help!

This article will take you through a full overview of everything you’ll need to know to do well, linking to more detailed articles and resources at each stage to let you really drill down into the details.

As well as traditional case interviews, we’ll also attend to the new formats in which cases are being delivered and otherwise make sure you’re up to speed with recent trends in this overall part of consulting recruitment.

Before we can figure out how to prepare for a case interview, though, we will first have to properly understand in detail what exactly you are up against. What format does a standard consulting case interview take? What is expected of you? How will you be assessed?

2. What is a case interview?

Before we can hope to tackle a case interview, we have to understand what one is.

In short, a case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer.

This case study will be a business problem where you have to advise a client - that is, an imaginary business or similar organisation in need of guidance.

You must help this client solve a problem and/or make a decision. This requires you to analyse the information you are given about that client organisation and figure out a final recommendation for what they should do next.

Business problems in general obviously vary in difficulty. Some are quite straightforward and can be addressed with fairly standard solutions. However, consulting firms exist precisely to solve the tough issues that businesses have failed to deal with internally - and so consultants will typically work on complex, idiosyncratic problems requiring novel solutions.

Some examples of case study questions might be:

• How much would you pay for a banking licence in Ghana?
• Estimate the potential value of the electric vehicle market in Germany
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms need the brightest minds they can find to put to work on these important, difficult projects. You can expect the case studies you have to solve in interview, then, to echo the unique, complicated problems consultancies deal with every day. As we’ll explain here, this means that you need to be ready to think outside the box to figure out genuinely novel solutions.

2.1. Where are case interviews in the consulting selection process?

Not everyone who applies to a consulting firm will have a case interview - far from it!

In fact, case interviews are pretty expensive and inconvenient for firms to host, requiring them to take consultants off active projects and even fly them back to the office from location for in-person interviews (although this happens less frequently now). Ideally, firms want to cut costs and save time by narrowing down the candidate pool as much as possible before any live interviews.

As such, there are some hoops to jump through before you make it to interview rounds.

Firms will typically eliminate as much as 80% of the applicant pool before interviews start . For most firms, 50%+ of applicants might be cut based on resumes, before a similar cut is made on those remaining based on aptitude tests. McKinsey currently gives their Solve assessment to most applicants, but will use their resulting test scores alongside resumes to cut 70%+ of the candidate pool before interviews.

You'll need to be on top of your game to get as far as a case interview with a top firm. Getting through the resume screen and any aptitude tests is an achievement in itself! Also we need to note that the general timeline of an application can differ depending on a series of factors, including which position you apply, your background, and the office you are applying to. For example, an undergraduate applying for a Business Analyst position (the entry level job at McKinsey) will most likely be part of a recruitment cycle and as such have pretty fixed dates when they need to sit the pre-screening test, and have the first and second round interviews (see more on those below). Conversely, an experienced hire will most likely have a much greater choice of test and interview dates as well as more time at their disposal to prepare.

For readers not yet embroiled in the selection process themselves, let’s put case interviews in context and take a quick look at each stage in turn. Importantly, note that you might also be asked to solve case studies outside interviews as well…

2.1.1. Application screen

It’s sometimes easy to forget that such a large cut is made at the application stage. At larger firms, this will mean your resume and cover letter is looked at by some combination of AI tools, recruitment staff and junior consulting staff (often someone from your own university).

Only the best applications will be passed to later stages, so make sure to check out our free resume and cover letter guides, and potentially get help with editing , to give yourself the best chance possible.

2.1.2. Aptitude tests and online cases

This part of the selection process has been changing quickly in recent years and is increasingly beginning to blur into the traditionally separate case interview rounds.

In the past, GMAT or PST style tests were the norm. Firms then used increasingly sophisticated and often gamified aptitude tests, like the Pymetrics test currently used by several firms, including BCG and Bain, and the original version of McKinsey’s Solve assessment (then branded as the Problem Solving Game).

Now, though, there is a move towards delivering relatively sophisticated case studies online. For example, McKinsey has replaced half the old Solve assessment with an online case. BCG’s Casey chatbot case now directly replaces a live first round case interview, and in the new era of AI chatbots, we expect these online cases to quickly become more realistic and increasingly start to relieve firms of some of the costs of live case interviews.

Our consultants collectively reckon that, over time, 50% of case interviews are likely to be replaced with these kinds of cases . We give some specific advice for online cases in section six. However, the important thing to note is that these are still just simulations of traditional case interviews - you still need to learn how to solve cases in precisely the same way, and your prep will largely remain the same.

2.1.3. Rounds of Interviews

Now, let’s not go overboard with talk of AI. Even in the long term, the client facing nature of consulting means that firms will have live case interviews for as long as they are hiring anyone. And in the immediate term, case interviews are still absolutely the core of consulting selection.

Before landing an offer at McKinsey, Bain, BCG or any similar firm, you won’t just have one case interview, but will have to complete four to six case interviews, usually divided into two rounds, with each interview lasting approximately 50-60 minutes .

Being invited to first round usually means two or three case interviews. As noted above, you might also be asked to complete an online case or similar alongside your first round interviews.

If you ace first round, you will be invited to second round to face the same again, but more gruelling. Only then - after up to six case interviews in total, can you hope to receive an offer.

2.2. Differences between first and second round interviews

Despite case interviews in the first and second round following the same format, second/final round interviews will be significantly more intense . The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.3. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

Being concise and to the point is key in many areas, networking being one for them. For more detail on all this, check out our full article on delivering recommendations .

Prep the right way

3. types of case interview.

While most case interviews share a similar structure, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

3.1. Different case objectives

A guiding thread throughout this article and our approach in general will be to treat each case as a self-contained problem and not try to pigeonhole it into a certain category. Having said that, there are of course similarities between cases and we can identify certain parameters and objectives.

Broadly speaking, cases can be divided into issue-based cases and strategic decision cases. In the former you will be asked to solve a certain issue, such as declining profits, or low productivity whereas in the latter you will be ask whether your client should or should not do something, such as enter a specific market or acquire another company. The chart below is a good breakdown of these different objectives:

3.2. How do interviewers craft cases

While interviewers will very likely be given a case bank to choose from by their company, a good number of them will also choose to adapt the cases they would currently be working on to a case interview setting. The difference is that the latter cases will be harder to pigeonhole and apply standard frameworks to, so a tailored approach will be paramount.

If you’ve applied for a specific practice or type of consulting - such as operational consulting, for example - it’s very likely that you will receive a case geared towards that particular area alongside a ‘generalist’ consulting case (however, if that’s the case, you will generally be notified). The other main distinction when it comes to case interviews is between interviewer-led and candidate-led.

3.3. Candidate-led cases

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms. From a structuring perspective, it’s easier to lose direction in a candidate-led case as there are no sign-posts along the way. As such, you need to come up with an approach that is both broad enough to cover all of the potential drivers in a case but also tailored enough to the problem you are asked to solve. It’s also up to you to figure out when you need to delve deeper into a certain branch of the case, brainstorm or ask for data. The following case from Bain is an excellent example on how to navigate a candidate-led case.

3.4. Interviewer-led cases

This type of case - employed most famously by McKinsey - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially. These cases are easier to follow as the interviewer will guide you in the right direction. However, this doesn’t mean you should pay less attention to structure and deliver a generic framework! Also, usually (but not always!) the first question will ask you to map your approach and is the equivalent of the structuring question in candidate-led cases. Sometimes, if you’re missing key elements, the interviewer might prompt you in the right direction - so make sure to take those prompts seriously as they are there to help you get back on track (ask for 30 seconds to think on the prompt and structure your approach). Other times - and this is a less fortunate scenario - the interviewer might say nothing and simply move on to the next question. This is why you should put just as much thought (if not more) into the framework you build for interviewer-led cases , as you may be penalized if you produce something too generic or that doesn’t encompass all the issues of the case.

3.5. Case and fit

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

3.5.1 Differences between firms

For the most part, a case interview is a case interview. However, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

3.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions , focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article . However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

3.6. What is different in 2023?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run . Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and case interview blurs. Online cases don’t just reduce the number of candidates to case interview, but start directly replacing them.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview.

Casey, at time of writing, is still a relatively “basic” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews.

Luckily, despite any changes in specific case interview format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI administered cases.

3.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated case interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

4. How to solve cases with the Problem-Driven Structure?

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your case interviews.

To address this problem, the MyConsultingCoach team has synthesized a new approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case interview, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same (see the method in action in the video below)

Let's zoom in to see how our method actually works in more detail:

4.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

4.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

4.2.1 Issue trees

Issue trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

4.2.2 Hypothesis trees

Hypothesis trees are similar, the only difference being that rather than just trying to break up the issue into smaller issues you are assuming that the problem can be solved and you are formulating solutions.

In the example above, you would assume revenues can be increased by either increasing the average ticket price or the number of customers . You can then hypothesize that you can increase the average occupancy rate in three ways: align the schedule of short and long haul flights, run a promotion to boost occupancy in off-peak times, or offer early bird discounts.

4.2.3 Other structures:structured lists

Structured lists are simply subcategories of a problem into which you can fit similar elements. This McKinsey case answer starts off by identifying several buckets such as retailer response, competitor response, current capabilities and brand image and then proceeds to consider what could fit into these categories.

Buckets can be a good way to start the structure of a complex case but when using them it can be very difficult to be MECE and consistent, so you should always aim to then re-organize them into either an issue or a hypothesis tree.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues. Ultimately all these lists are methods to set out a logical hierachy among elements.

4.2.4 Structures in practice

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

4.2. Lead the analysis

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level and considering the 80/20 rule(see below), solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

4.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In a case interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

4.5. What if I get stuck?

Naturally with case interviews being difficult problems there may be times where you’re unsure what to do or which direction to take. The most common scenario is that you will get stuck midway through the case and there are essentially two things that you should do:

• 1. Go back to your structure
• 2. Ask the interviewer for clarification

Your structure should always be your best friend - after all, this is why you put so much thought and effort into it: if it’s MECE it will point you in the right direction. This may seem abstract but let’s take the very simple example of a profitability case interview: if you’ve started your analysis by segmenting profit into revenue minus costs and you’ve seen that the cost side of the analysis is leading you nowhere, you can be certain that the declining profit is due to a decline in revenue.

Similarly, when you’re stuck on the quantitative section of the case interview, make sure that your framework for calculations is set up correctly (you can confirm this with the interviewer) and see what it is you’re trying to solve for: for example if you’re trying to find what price the client should sell their new t-shirt in order to break even on their investment, you should realize that what you’re trying to find is the break even point, so you can start by calculating either the costs or the revenues. You have all the data for the costs side and you know they’re trying to sell 10.000 pairs so you can simply set up the equation with x being the price.

As we’ve emphasised on several occasions, your case interview will be a dialogue. As such, if you don’t know what to do next or don’t understand something, make sure to ask the interviewer (and as a general rule always follow their prompts as they are trying to help, not trick you). This is especially true for the quantitative questions, where you should really understand what data you’re looking at before you jump into any calculations. Ideally you should ask your questions before you take time to formulate your approach but don’t be afraid to ask for further clarification if you really can’t make sense of what’s going on. It’s always good to walk your interviewer through your approach before you start doing the calculations and it’s no mistake to make sure that you both have the same understanding of the data. For example when confronted with the chart below, you might ask what GW (in this case gigawatt) means from the get-go and ask to confirm the different metrics (i.e. whether 1 GW = 1000 megawatts). You will never be penalised for asking a question like that.

5. What to remember in case interviews

If you’re new to case cracking you might feel a bit hopeless when you see a difficult case question, not having any idea where to start.

In fact though, cracking case interviews is much like playing chess. The rules you need to know to get started are actually pretty simple. What will make you really proficient is time and practice.

In this section, we’ll run through a high level overview of everything you need to know, linking to more detailed resources at every step.

5.1. An overall clear structure

You will probably hear this more than you care for but it is the most important thing to keep in mind as you start solving cases, as not only it is a key evaluation criterion but the greatest tool you will have at your disposal. The ability to build a clear structure in all aspects of the case inteview will be the difference between breezing through a complicated case and struggling at its every step. Let’s look a bit closer at the key areas where you should be structured!

5.1.1 Structured notes

Every case interview starts with a prompt, usually verbal, and as such you will have to take some notes. And here is where your foray into structure begins, as the notes you take should be clear, concise and structured in a way that will allow you to repeat the case back to the interviewer without writing down any unnecessary information.

This may sound very basic but you should absolutely not be dismissive about it: taking clear and organized notes will allow what we found helps is to have separate sections for:

• The case brief
• Follow-up questions and answers
• Numerical data
• Case structure (the most crucial part when solving the case)
• Any scrap work during the case (usually calculations)

When solving the case - or, as we call it here, in the Lead the analysis step, it is highly recommended to keep on feeding and integrating your structure, so that you never get lost. Maintaining a clear high level view is one of the most critical aspects in case interviews as it is a key skill in consulting: by constantly keeping track of where you are following your structure, you’ll never lose your focus on the end goal.

In the case of an interviewer-led case, you can also have separate sheets for each question (e.g. Question 1. What factors can we look at that drive profitability?). If you develop a system like this you’ll know exactly where to look for each point of data rather than rummage around in untidy notes. There are a couple more sections that you may have, depending on preference - we’ll get to these in the next sections.

5.1.2 Structured communication

There will be three main types of communication in cases:

• 1. Asking and answering questions
• 2. Walking the interviewer through your structure (either the case or calculation framework - we’ll get to that in a bit!)
• 3. Delivering your recommendation

Asking and answering questions will be the most common of these and the key thing to do before you speak is ask for some time to collect your thoughts and get organised. What you want to avoid is a ‘laundry list’ of questions or anything that sounds too much like a stream of consciousness.

Different systems work for different candidates but a sure-fire way of being organised is numbering your questions and answers. So rather than saying something like ‘I would like to ask about the business model, operational capacity and customer personas’ it’s much better to break it down and say something along the lines of ‘I’ve got three key questions. Firstly I would like to inquire into the business model of our client. Secondly I would like to ask about their operational capacity. Thirdly I would like to know more about the different customer personas they are serving’.

A similar principle should be applied when walking the interviewer through your structure, and this is especially true of online case interviews (more and more frequent now) when the interviewer can’t see your notes. Even if you have your branches or buckets clearly defined, you should still use a numbering system to make it obvious to the interviewer. So, for example, when asked to identify whether a company should make an acquisition, you might say ‘I would like to examine the following key areas. Firstly the financial aspects of this issue, secondly the synergies and thirdly the client’s expertise’

The recommendation should be delivered top-down (see section 4.4 for specifics) and should employ the same numbering principle. To do so in a speedy manner, you should circle or mark the key facts that you encounter throughout the case so you can easily pull them out at the end.

5.1.3 Structured framework

It’s very important that you have a systematic approach - or framework - for every case. Let’s get one thing straight: there is a difference between having a problem-solving framework for your case and trying to force a case into a predetermined framework. Doing the former is an absolute must , whilst doing the latter will most likely have you unceremoniously dismissed.

We have seen there are several ways of building a framework, from identifying several categories of issues (or ‘buckets’) to building an issue or hypothesis tree (which is the most efficient type of framework). For the purpose of organization, we recommend having a separate sheet for the framework of the case, or, if it’s too much to manage, you can have it on the same sheet as the initial case prompt. That way you’ll have all the details as well as your proposed solution in one place.

5.1.4 Structured calculations

Whether it’s interviewer or candidate-led, at some point in the case you will get a bunch of numerical data and you will have to perform some calculations (for the specifics of the math you’ll need on consulting interviews, have a look at our Consulting Math Guide ). Here’s where we urge you to take your time and not dive straight into calculating! And here’s why: while your numerical agility is sure to impress interviewers, what they’re actually looking for is your logic and the calculations you need to perform in order to solve the problem . So it’s ok if you make a small mistake, as long as you’re solving for the right thing.

As such, make it easy for them - and yourself. Before you start, write down in steps the calculations you need to perform. Here’s an example: let’s say you need to find out by how much profits will change if variable costs are reduced by 10%. Your approach should look something like:

• 1. Calculate current profits: Profits = Revenues - (Variable costs + Fixed costs)
• 2. Calculate the reduction in variable costs: Variable costs x 0.9
• 3. Calculate new profits: New profits = Revenues - (New variable costs + Fixed costs)

Of course, there may be more efficient ways to do that calculation, but what’s important - much like in the framework section - is to show your interviewer that you have a plan, in the form of a structured approach. You can write your plan on the sheet containing the data, then perform the calculations on a scrap sheet and fill in the results afterward.

5.2. Common business knowledge and formulas

Although some consulting firms claim they don’t evaluate candidates based on their business knowledge, familiarity with basic business concepts and formulae is very useful in terms of understanding the case studies you are given in the first instance and drawing inspiration for structuring and brainstorming.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already. For those coming from a different background, it may be useful to cover some.

Luckily, you don’t need a degree-level understanding of business to crack case interviews , and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy Course course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Below we include a few elementary concepts and formulae so you can hit the ground running in solving cases. We should note that you should not memorise these and indeed a good portion of them can be worked out logically, but you should have at least some idea of what to expect as this will make you faster and will free up much of your mental computing power. In what follows we’ll tackle concepts that you will encounter in the private business sector as well as some situations that come up in cases that feature clients from the NGO or governmental sector.

5.2.1 Business sector concepts

These concepts are the bread and butter of almost any business case so you need to make sure you have them down. Naturally, there will be specificities and differences between cases but for the most part here is a breakdown of each of them.

5.2.1.1. Revenue

The revenue is the money that the company brings in and is usually equal to the number of products they sell multiplied to the price per item and can be expressed with the following equation:

Revenue = Volume x Price

Companies may have various sources of revenue or indeed multiple types of products, all priced differently which is something you will need to account for in your case interview. Let’s consider some situations. A clothing company such as Nike will derive most of their revenue from the number of products they sell times the average price per item. Conversely, for a retail bank revenue is measured as the volume of loans multiplied by the interest rate at which the loans are given out. As we’ll see below, we might consider primary revenues and ancillary revenues: in the case of a football club, we might calculate primary revenues by multiplying the number of tickets sold by the average ticket price, and ancillary revenues those coming from sales of merchandise (similarly, let’s say average t-shirt price times the number of t-shirts sold), tv rights and sponsorships.

These are but a few examples and another reminder that you should always aim to ask questions and understand the precise revenue structure of the companies you encounter in cases.

5.2.1.2. Costs

The costs are the expenses that a company incurs during its operations. Generally, they can be broken down into fixed and variable costs :

Costs = Fixed Costs + Variable Costs

As their name implies, fixed costs do not change based on the number of units produced or sold. For example, if you produce shoes and are renting the space for your factory, you will have to pay the rent regardless of whether you produce one pair or 100. On the other hand, variable costs depend on the level of activity, so in our shoe factory example they would be equivalent to the materials used to produce each pair of shoes and would increase the more we produce.

These concepts are of course guidelines used in order to simplify the analysis in cases, and you should be aware that in reality often the situation can be more complicated. However, this should be enough for case interviews. Costs can also be quasi-fixed, in that they increase marginally with volume. Take the example of a restaurant which has a regular staff, incurring a fixed cost but during very busy hours or periods they also employ some part-time workers. This cost is not exactly variable (as it doesn’t increase with the quantity of food produced) but also not entirely fixed, as the number of extra hands will depend on how busy the restaurant is. Fixed costs can also be non-linear in nature. Let’s consider the rent in the same restaurant: we would normally pay a fixed amount every month, but if the restaurant becomes very popular we might need to rent out some extra space so the cost will increase. Again, this is not always relevant for case interviews.

5.2.1.3. Profit and profit margin

The profit is the amount of money a company is left with after it has paid all of its expenses and can be expressed as follows:

Profit = Revenue - Costs

It’s very likely that you will encounter a profitability issue in one of your case interviews, namely you will be asked to increase a company’s profit. There are two main ways of doing this: increasing revenues and reducing costs , so these will be the two main areas you will have to investigate. This may seem simple but what you will really need to understand in a case are the key drivers of a business (and this should be done through clarifying questions to the interviewer - just as a real consultant would question their client).

For example, if your client is an airline you can assume that the main source of revenue is sales of tickets, but you should inquire how many types of ticket the specific airline sells. You may naturally consider economy and business class tickets, but you may find out that there is a more premium option - such as first class - and several in-between options. Similarly to our football club example, there may be ancillary revenues from selling of food and beverage as well as advertising certain products or services on flights.

You may also come across the profit margin in case interviews. This is simply the percentage of profit compared to the revenue and can be expressed as follows:

Profit margin = Profit/Revenue x 100

5.2.1.4. Break-even point

An ancillary concept to profit, the break-even point is the moment where revenues equal costs making the profit zero and can be expressed as the following equation:

Revenues = Costs (Fixed costs + Variable costs)

This formula will be useful when you are asked questions such as ‘What is the minimum price I should sell product X?’ or ‘What quantity do I need to sell in order to recoup my investment?’. Let’s say in a case interview an owner of a sandwich store asks us to figure out how many salami and cheese salami sandwiches she needs to sell in order to break even. She’s spending $4 on salami and $2 for cheese and lettuce per sandwich, and believes she can sell the sandwiches at around $7. The cost of utilities and personnel is around $5000 per month. We could lay this all out in the break-even equation:

7 x Q ( quantity ) = (4+2) x Q + 5000 ( variable + fixed costs )

In a different scenario, we may be asked to calculate the break-even price . Let’s consider our sandwich example and say our owner knows she has enough ingredients for about 5000 sandwiches per month but is not sure how much to sell them for. In that case, if we know our break-even equation, we can simply make the following changes:

P ( price ) x 5000 = (4+2) x 5000 + 5000

By solving the equation we get to the price of $7 per sandwich.

5.2.1.5. Market share and market size

We can also consider the market closely with profit, as in fact the company’s performance in the market is what drives profits. The market size is the total number of potential customers for a certain business or product, whereas the market share is the percentage of that market that your business controls (or could control, depending on the case).

There is a good chance you will have to estimate the market size in one of your case interviews and we get into more details on how to do that below. You may be asked to estimate this in either number of potential customers or total value . The latter simply refers to the number of customers multiplied by the average value of the product or service.

To calculate the market share you will have to divide the company’s share by the total market size and multiply by 100:

Note, though, that learning the very basics of business is the beginning rather than the end of your journey. Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved. The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

5.3 Public sector and NGO concepts

As we mentioned, there will be some cases (see section 6.6 for a more detailed example) where the key performance indicators (or KPIs in short) will not be connected to profit. The most common ones will involve the government of a country or an NGO, but they can be way more diverse and require more thought and application of first principles. We have laid out a couple of the key concepts or KPIs that come up below

5.3.1 Quantifiability

In many such scenarios you will be asked to make an important strategic decision of some kind or to optimise a process. Of course these are not restricted to non-private sector cases but this is where they really come into their own as there can be great variation in the type of decision and the types of field.

While there may be no familiar business concepts to anchor yourself onto, a concept that is essential is quantifiability . This means, however qualitative the decision might seem, consultants rely on data so you should always aim to have aspects of a decision that can be quantified, even if the data doesn’t present itself in a straightforward manner.

Let’s take a practical example. Your younger sibling asks you to help them decide which university they should choose if they want to study engineering. One way to structure your approach would be to segment the problem into factors affecting your sibling’s experience at university and experience post-university. Within the ‘at uni’ category you might think about the following:

• Financials : How much are tuition costs and accommodation costs?
• Quality of teaching and research : How are possible universities ranked in the QS guide based on teaching and research?
• Quality of resources : How well stocked is their library, are the labs well equipped etc.?
• Subject ranking : How is engineering at different unis ranked?
• Life on campus and the city : What are the living costs in the city where the university is based? What are the extracurricular opportunities and would your sibling like to live in that specific city based on them?

Within the ‘out of uni’ category you might think about:

• Exit options : What are the fields in which your sibling could be employed and how long does it take the average student of that university to find a job?
• Alumni network : What percentage of alumni are employed by major companies?
• Signal : What percentage of applicants from the university get an interview in major engineering companies and related technical fields?

You will perhaps notice that all the buckets discussed pose quantifiable questions meant to provide us with data necessary to make a decision. It’s no point to ask ‘Which university has the nicest teaching staff?’ as that can be a very subjective metric.

5.3.1 Impact

Another key concept to consider when dealing with sectors other than the private one is how impactful a decision or a line of inquiry is on the overarching issue , or whether all our branches in our issue tree have a similar impact. This can often come in the form of impact on lives, such as in McKinsey’s conservation case discussed below, namely how many species can we save with our choice of habitat.

5.4 Common consulting concepts

Consultants use basic business concepts on an every day basis, as they help them articulate their frameworks to problems. However, they also use some consulting specific tools to quality check their analysis and perform in the most efficient way possible. These principles can be applied to all aspects of a consultant’s work, but for brevity we can say they mostly impact a consultant’s systematic approach and communication - two very important things that are also tested in case interviews. Therefore, it’s imperative that you not only get to know them, but learn how and when to use them as they are at the very core of good casing. They are MECE-ness, the Pareto Principle and the Pyramid principle and are explained briefly below - you should, however, go on to study them in-depth in their respective articles.

Perhaps the central pillar of all consulting work and an invaluable tool to solve cases, MECE stands for Mutually Exclusive and Collectively Exhaustive . It can refer to any and every aspect in a case but is most often used when talking about structure. We have a detailed article explaining the concept here , but the short version is that MECE-ness ensures that there is no overlap between elements of a structure (i.e. the Mutually Exclusive component) and that it covers all the drivers or areas of a problem (Collectively Exhaustive). It is a concept that can be applied to any segmentation when dividing a set into subsets that include it wholly but do not overlap.

Let’s take a simple example and then a case framework example. In simple terms, when we are asked to break down the set ‘cars’ into subsets, dividing cars into ‘red cars’ and ‘sports cars’ is neither mutually exclusive (as there are indeed red sports cars) nor exhaustive of the whole set (i.e. there are also yellow non-sports cars that are not covered by this segmentation). A MECE way to segment would be ‘cars produced before 2000’ and ‘cars produced after 2000’ as this segmentation allows for no overlap and covers all the cars in existence.

Dividing cars can be simple, but how can we ensure MECEness in a case-interview a.k.a. a business situation. While the same principles apply, a good tip to ensure that your structure is MECE is to think about all the stakeholders - i.e. those whom a specific venture involves.

Let’s consider that our client is a soda manufacturer who wants to move from a business-to-business strategy, i.e. selling to large chains of stores and supermarkets, to a business-to-consumer strategy where it sells directly to consumers. In doing so they would like to retrain part of their account managers as direct salespeople and need to know what factors to consider.

A stakeholder-driven approach would be to consider the workforce and customers and move further down the issue tree, thinking about individual issues that might affect them. In the case of the workforce, we might consider how the shift would affect their workload and whether it takes their skillset into account. As for the customers, we might wonder whether existing customers would be satisfied with this move: will the remaining B2B account managers be able to provide for the needs of all their clients and will the fact that the company is selling directly to consumers now not cannibalise their businesses? We see how by taking a stakeholder-centred approach we can ensure that every single perspective and potential issue arising from it is fully covered.

5.4.2 The Pareto Principle

Also known as the 80/20 rule, this principle is important when gauging the impact of a decision or a factor in your analysis. It simply states that in business (but not only) 80% of outcomes come from 20% of causes. What this means is you can make a few significant changes that will impact most of your business organisation, sales model, cost structure etc.

Let’s have a look at 3 quick examples to illustrate this:

• 80% of all accidents are caused by 20% of drivers
• 20% of a company’s products account for 80% of the sales
• 80% of all results in a company are driven by 20% of its employees

The 80/20 rule will be a very good guide line in real engagements as well as case interviews, as it will essentially point to the easiest and most straightforward way of doing things. Let’s say one of the questions in a case is asking you to come up with an approach to understand the appeal of a new beard trimmer. Obviously you can’t interview the whole male population so you might think about setting up a webpage and asking people to comment their thoughts. But what you would get would be a laundry list of difficult to sift through data.

Using an 80/20 approach you would segment the population based on critical factors (age groups, grooming habits etc.) and then approach a significant sample size of each (e.g. 20), analysing the data and reaching a conclusion.

5.4.3 The Pyramid Principle

This principle refers to organising your communication in a top-down , efficient manner. While this is generally applicable, the pyramid principle will most often be employed when delivering the final recommendation to your client. This means - as is implicit in the name - that you would organise your recommendation (and communication in general) as a pyramid, stating the conclusion or most important element at the top then go down the pyramid listing 3 supporting arguments and then further (ideally also 3) supporting arguments for those supporting arguments.

Let’s look at this in practice in a case interview context: your client is a German air-conditioning unit manufacturer who was looking to expand into the French market. However, after your analysis you’ve determined that the market share they were looking to capture would not be feasible. A final recommendation using the Pyramid Principle would sound something like this: ‘I recommend that we do not enter the German market for the following three reasons. Firstly, the market is too small for our ambitions of $50 million. Secondly the market is heavily concentrated, being controlled by three major players and our 5 year goal would amount to controlling 25% of the market, a share larger than that of any of the players. Thirdly, the alternative of going into the corporate market would not be feasible, as it has high barriers to entry.Then, if needed, we could delve deeper into each of our categories

6. Case examples or building blocks?

As we mentioned before, in your case interview preparation you will undoubtedly find preparation resources that claim that there are several standard types of cases and that there is a general framework that can be applied to each type of case. While there are indeed cases that are straightforward at least in appearance and seemingly invite the application of such frameworks, the reality is never that simple and cases often involve multiple or more complicated components that cannot be fitted into a simple framework.

At MCC we don’t want you to get into the habit of trying to identify which case type you’re dealing with and pull out a framework, but we do recognize that there are recurring elements in frameworks that are useful - such as the profitability of a venture (with its revenues and costs), the valuation of a business, estimating and segmenting a market and pricing a product.

We call these building blocks because they can be used to build case frameworks but are not a framework in and of themselves, and they can be shuffled around and rearranged in any way necessary to be tailored to our case. Hence, our approach is not to make you think in terms of case types but work from first principles and use these building blocks to build your own framework. Let’s take two case prompts to illustrate our point.

The first is from the Bain website, where the candidate is asked whether they think it’s a good idea for their friend to open a coffee shop in Cambridge UK (see the case here ). The answer framework provided here is a very straightforward profitability analysis framework, examining the potential revenues and potential costs of the venture:

While this is a good point to start for your case interview (especially taken together with the clarifying questions), we will notice that this approach will need more tailoring to the case - for example the quantity of coffee will be determined by the market for coffee drinkers in Cambridge, which we have to determine based on preference. We are in England so a lot of people will be drinking tea but we are in a university town so perhaps more people than average are drinking coffee as it provides a better boost when studying. All these are some much needed case-tailored hypotheses that we can make based on the initial approach.

Just by looking at this case we might be tempted to say that we can just take a profitability case and apply it without any issues. However, this generic framework is just a starting point and in reality we would need to tailor it much further in the way we had started to do in order to get to a satisfactory answer. For example, the framework for this specific case interview doesn’t cover aspects such as the customer’s expertise: does the friend have any knowledge of the coffee business, such as where to source coffee and how to prepare it? Also, we could argue there may be some legal factors to consider here, such as any approvals that they might need from the city council to run a coffee shop on site, or some specific trade licences that are not really covered in the basic profitability framework.

Let’s take a different case , however, from the McKinsey website. In this scenario, the candidate is being asked to identify some factors in order to choose where to focus the client’s conservation efforts. Immediately we can realise that this case doesn’t lend itself to any pre-packaged framework and we will need to come up with something from scratch - and take a look at McKinsey’s answer of the areas to focus on:

We notice immediately that this framework is 100% tailored to the case - of course there are elements which we encounter in other cases, such as costs and risks but again these are applied in an organic way. It’s pretty clear that while no standard framework would work in this case, the aforementioned concepts - costs and risks - and the way to approach them (a.k.a building blocks ) are fundamentally similar throughout cases (with the obvious specificities of each case).

In what follows, we’ll give a brief description of each building block starting from the Bain example discussed previously, in order to give you a general idea of what they are and their adaptability, but you should make sure to follow the link to the in-depth articles to learn all their ins and outs.

6.1 Estimates and segmentation

This building block will come into play mostly when you’re thinking about the market for a certain product (but make sure to read the full article for more details). Let’s take our Bain Cambridge coffee example. As we mentioned under the quantity bucket we need to understand what the market size for coffee in Cambridge would be - so we can make an estimation based on segmentation .

The key to a good estimation is the ability to logically break down the problem into more manageable pieces. This will generally mean segmenting a wider population to find a particular target group. We can start off with the population of Cambridge - which we estimate at 100.000. In reality the population is closer to 150.000 but that doesn’t matter - the estimation has to be reasonable and not accurate , so unless the interviewer gives you a reason to reconsider you can follow your instinct. We can divide that into people who do and don’t drink coffee. Given our arguments before, we can conclude that 80% of those, so 80.000 drink coffee. Then we can further segment into those who drink regularly - let’s say every day - and those who drink occasionally - let’s say once a week. Based on the assumptions before about the student population needing coffee to function, and with Cambridge having a high student population, we can assume that 80% of those drinking coffee are regular drinkers, so that would be 64.000 regular drinkers and 16.000 occasional drinkers. We can then decide whom we want to target what our strategy needs to be:

This type of estimation and segmentation can be applied to any case specifics - hence why it is a building block.

6.2 Profitability

We had several looks at this building block so far (see an in-depth look here ) as it will show up in most case interivew scenarios, since profit is a key element in any company’s strategy. As we have seen, the starting point to this analysis is to consider both the costs and revenues of a company, and try to determine whether revenues need to be improved or whether costs need to be lowered. In the coffee example, the revenues are dictated by the average price per coffe x the number of coffees sold , whereas costs can be split into fixed and variable .

Some examples of fixed costs would be the rent for the stores and the cost of the personnel and utilities, while the most obvious variable costs would be the coffee beans used and the takeaway containers (when needed). We may further split revenues in this case into Main revenues - i.e. the sales of coffee - and Ancillary revenues , which can be divided into Sales of food products (sales of pastries, sandwiches etc., each with the same price x quantity schema) and Revenues from events - i.e renting out the coffee shop to events and catering for the events themselves. Bear in mind that revenues will be heavily influenced by the penetration rate , i.e. the share of the market which we can capture.

6.3 Pricing

Helping a company determine how much they should charge for their goods or services is another theme that comes up frequently in cases. While it may seem less complicated than the other building blocks, we assure you it’s not - you will have to understand and consider several factors, such as the costs a company is incurring, their general strategic positioning, availability, market trends as well as the customers’ willingness to pay (or WTP in short) - so make sure to check out our in-depth guide here .

In our example, we may determine that the cost per cup (coffee beans, staff, rent) is £1. We want to be student friendly so we should consider how much students would want to pay for a coffee as well as how much are competitors are charging. Based on those factors, it would be reasonable to charge on average £2 per cup of coffee. It’s true that our competitors are charging £3 but they are targeting mostly the adult market, whose willingness to pay is higher, so their pricing model takes that into account as well as the lower volume of customers in that demographic.

6.4. Valuation

A variant of the pricing building block, a valuation problem generally asks the candidate to determine how much a client should pay for a specific company (the target of an acquisition) as well as what other factors to consider. The two most important factors (but not the only ones - for a comprehensive review see our Valuation article ) to consider are the net present value (in consulting interviews usually in perpetuity) and the synergies .

In short, the net present value of a company is how much profit it currently brings in, divided by how much that cash flow will depreciate in the future and can be represented with the equation below:

The synergies refer to what could be achieved should the companies operate as one, and can be divided into cost and revenue synergies .

Let’s expand our coffee example a bit to understand these. Imagine that our friend manages to open a chain of coffee shops in Cambridge and in the future considers acquiring a chain of take-out restaurants. The most straightforward example of revenue synergies would be cross-selling, in this case selling coffee in the restaurants as well as in the dedicated stores, and thus getting an immediate boost in market share by using the existing customers of the restaurant chain. A cost synergy would be merging the delivery services of the two businesses to deliver both food and coffee, thus avoiding redundancies and reducing costs associated with twice the number of drivers and vehicles.

6.5. Competitive interaction

This component of cases deals with situations where the market in which a company is operating changes and the company must decide what to do. These changes often have to do with a new player entering the market (again for more details make sure to dive into the Competitive Interaction article ).

Let’s assume that our Cambridge coffee shop has now become a chain and has flagged up to other competitors that Cambridge is a blooming market for coffee. As such, Starbucks has decided to open a few stores in Cambridge themselves, to test this market. The question which might be posed to a candidate is what should our coffee chain do. One way (and a MECE one) to approach the problem is to decide between doing something and doing nothing . We might consider merging with another coffee chain and pooling our resources or playing to our strengths and repositioning ourselves as ‘your student-friendly, shop around the corner’. Just as easily we may just wait the situation out and see whether indeed Starbucks is cutting into our market share - after all, the advantages of our product and services might speak for themselves and Starbucks might end up tanking. Both of these are viable options if argued right and depending on the further specifics of the case.

6.6. Special cases

Most cases deal with private sectors, where the overarching objective entails profit in some form. However, as hinted before, there are cases which deal with other sectors where there are other KPIs in place . The former will usually contain one or several of these building blocks whereas the latter will very likely have neither. This latter category is arguably the one that will stretch your analytical and organisational skills to the limit, since there will be very little familiarity that you can fall back on (McKinsey famously employs such cases in their interview process).

So how do we tackle the structure for such cases? The short answer would be starting from first principles and using the problem driven structure outlined above, but let’s look at a quick example in the form of a McKinsey case :

The first question addressed to the candidate is the following:

This is in fact asking us to build a structure for the case. So what should we have in mind here? Most importantly, we should start with a structure that is MECE and we should remember to do that by considering all the stakeholders . They are on the one hand the government and affiliated institutions and on the other the population. We might then consider which issues might arise for each shareholder and what the benefits for them would be, as well as the risks. This approach is illustrated in the answer McKinsey provides as well:

More than anything, this type of case shows us how important it is to practise and build different types of structures, and think about MECE ways of segmenting the problem.

7. How Do I prepare for case interviews

In consulting fashion, the overall preparation can be structured into theoretical preparation and practical preparation , with each category then being subdivided into individual prep and prep with a partner .

As a general rule, the level and intensity of the preparation will differ based on your background - naturally if you have a business background (and have been part of a consulting club or something similar) your preparation will be less intensive than if you’re starting from scratch. The way we suggest you go about it is to start with theoretical preparation , which means learning about case interviews, business and basic consulting concepts (you can do this using free resources - such as the ones we provide - or if you want a more through preparation you can consider joining our Case Academy as well).

You can then move on to the practical preparation which should start with doing solo cases and focusing on areas of improvement, and then move on to preparation with a partner , which should be another candidate or - ideally - an ex-consultant.

Let’s go into more details with respect to each type of preparation.

7.1. Solo practice

The two most important areas of focus in sole preparation are:

• Mental math

As we mentioned briefly, the best use of your time is to focus on solving cases. You can start with cases listed on MBB sites since they are clearly stated and have worked solutions as well (e.g. Bain is a good place to start) and then move to more complex cases (our Case Library also offers a range of cases of different complexities). To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

Another important area of practice is your mental mathematics as this skill will considerably increase your confidence and is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

7.2. Preparation with a partner

There are aspects of a case interview - such as asking clarifying questions - which you cannot do alone and this is why, after you feel comfortable, you should move on to practice with another person. There are two options here:

• Practicing with a peer
• Practicing with an ex-consultant

In theory they can be complementary - especially if you’re peer is also preparing for consulting interviews - and each have advantages and disadvantages. A peer is likely to practice with you for free for longer, however you may end up reinforcing some bad habits or unable to get actionable feedback. A consultant will be able to provide you the latter but having their help for the same number of hours as a peer will come at a higher cost. Let’s look at each option in more detail.

7.2.1. Peer preparation

Once you have worked through eight cases solo, you should be ready to simulate the case interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting. If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice. We recommend practicing around 10 to 15 ‘live’ cases to really get to a point where you feel comfortable.

7.2.2. Preparation with a consultant

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Practicing with an ex consultant is essentialy a simulation of a case interview. Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even just a few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering bespoke mentoring programmes , where you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

7.3. Practice for online interviews

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

7.4. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

8. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

8.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the case interview can then begin.

8.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important . If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

8.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

8.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

8.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

8.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

You might have other case interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

8.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote case interviews are, in effect, around making sure you come across as effectively as you would in person.

8.2.1. Connection

It sounds trivial, but a successful video case interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

8.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

8.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom case interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your case interview actually is. If your case interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

8.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom case interview, but more so.

9. How we can help

A Quick Guide to Preparing for a Case Study Interview

Recruiting & Careers Social Influencer

Reviewed by Chris Leitch

Invited to participate in a case study interview but not sure about the best ways to get ready for it?

As you always want to be at your very best when interviewing with a company, the case study interview requires a bit more preparation than recognising some of the common types of job interviews .

While you’ll still need to impress a prospective employer with strong research, confident interview responses and a professional appearance , the case study interview tests your knowledge and abilities through a spontaneous, analytical exercise. It examines how you approach problem-solving with the pressure of handling a situation without previous knowledge of any details or context.

Although the consulting industry utilises it as an essential part of the hiring process, the case study interview can be also found in many other environments, including startups, government and corporate organisations. It measures a candidate’s analytical, logic reasoning and communication abilities while under pressure.

In this guide, we will cover what you need to know to successfully prepare for a case study interview.

Case Study Interviews Explained

Even if you’ve never participated in one, it’s likely you’ve heard stories about the case study interview format. The case study puts you, the candidate, on the spot to solve a business problem posed by the interviewers.

Case study interview questions cover a wide range of topics and do not look for a single ‘right’ answer. Instead, the format gives the interviewers a look at how you respond spontaneously while applying problem-solving skills to create a solution to the business challenge presented.

For example, an exercise might ask what the potential market size is for a vegan food company within a prospective city and if setting up shop within the region would be worth it. The case study may not share all the details to help you reach an answer, but it should prompt you to ask questions that help you structure your thought process.

What to Expect in a Case Study Interview

The ways by which a case study interview is conducted will vary by company. However, this format bears unique characteristics:

• You’ll receive an introduction to the business problem, its relevant details and other information that lend to setting context. Some companies may choose to share a briefing document for you to read, while others may prefer to communicate the scenario in conversation.
• Information about the business problem will be, to some degree, vague. While the problem may cover complex business concepts, expect that the information will provide a high-level description of the scenario – not detailed reports with specific facts and figures. Case study interviews present such information in general terms for a reason. They’re meant to provide just enough information so that you can choose how to approach your line of questioning to solve the problem.
• The discussion about the business problem will be led by either the interviewer or the candidate. You need to be prepared for both situations. Who leads the conversation about the business problem is important, as it reveals the direction the discussion will take.

In interviewer-led sessions, the interviewer seeks to gauge the quality of your approach as it relates to a specific part of the business problem. They control the dialogue, focusing on a series of tough questions unlike those considered to be difficult in other interview formats . The interviewer sticks to a line of questioning that refers to details and themes relevant to the business problem, and evaluates how you comprehend, interpret and recommend actions within this specific domain.

On the hand, candidate-led conversations evaluate your ability to understand a business problem comprehensively, and from multiple points of view. Consultants play different roles on projects. Their actions cover various levels of activity, from analysing the business facts and data, creating the solutions and communicating directly with the clients on the overall strategy and approach. You’ll need to show strong methodology to guide others in your process.

Candidate-led sessions are challenging because they give you the freedom to explain your best approach to tackle the entire problem, but without receiving the input or comments of others to help guide a conversation along.

How to Prepare for a Case Study Interview

As you might find these interviews to be difficult, intense and downright nerve-wracking , you can succeed in a case study interview through thoughtful preparation. Here are five tips to help you ace the interview:

1. Demonstrate Your Analytical, Reasoning and Communication Skills

While recapping key details of the business problem is important, the case study interview measures much more than your ability to recall the facts. It showcases how you think on your feet as you seek out information to determine your course of action.

While you might be comfortable sketching out a framework or a mathematical formula that helps you identify the way you wish to solve the problem, this interview format also tests your ability to explain the reasoning in a clear and believable manner to others.

To be successful in a case study interview, you must demonstrate the skill to process information quantitatively, as well as speak about your rationale and decisions convincingly.

2. Get Ready to Play an Active Role in the Discussion

Case study interviews require a high level of engagement. While other interviews might have you responding to questions with rehearsed answers, the case study interview presents a situation that is dynamic and unpredictable.

You’ll want to approach the session with an active disposition. This typically includes taking notes, documenting your observations and ideas, sketching out diagrams and charts, and asking follow-up questions throughout the interview .

3. Identify the Type of Problem Posed to You

Jobseekers may find that there are common themes that appear when covering the type of business problems found in case study interviews. Eight of the most common exercises explore these questions:

• Maths – eg: ‘How many more units do we need to sell to double the profit?’
• Market size – eg: ‘How big is the market size within the US for smart wearable devices?’
• Framework/Issue tree - eg: ‘Identify the factors you would consider in addressing the problem.’
• Data-chart insights – eg: ‘What story do the numbers tell about the operations of this business?’
• Value proposition – eg: ‘What factors do customers look for in choosing a mobile phone carrier?’
• Business valuation – eg: ‘Just how much is this company worth today, and would it change if acquired by our competitor?’
• Hypothesis – eg: ‘What are some possible reasons that explain this trend?’
• Brain teaser – eg: ‘How many tennis balls can you fit in an area that is twice the size of a football field?’

There is not a single approach that solves all business problems. By identifying the type of problem you’re encountering, you’ll be able to quickly determine the most appropriate method to apply.

For example, you might discover that a maths problem will rely on the knowledge of specific formulas and expressions, while a hypothesis question calls for a closer look at the root causes behind an issue.

4. Organise a Framework that Helps You Solve the Problem

Having a good framework to apply to a problem is the key to doing well in a case study interview. You want to show that you understand a business issue well enough to formulate recommendations or insights that address the problem. As there isn’t one right answer to such a problem, your interviewer will be interested to hear about the thought process you applied to arrive at your decisions.

The process may involve a range of problem-solving skills and methods, including the use of mathematical formulas, first-hand knowledge about an industry and decision-tree flowcharts that guide through questions you’ve applied to the issue.

It’s helpful to write down your framework and refer to it as needed. By having the steps outlined, you’ll be able to explain your recommendations in a clear and confident manner so that the rationale used in your analysis appears sound.

5. Practise, Practise, Practise!

Prepare for the case study interview by engaging in mock practice sessions before the big day. While it’s important to spend time putting together the methods you’ll use to analyse a business problem, enlisting the help of a friend or two familiar with this interview format is essential.

You’ll want to find case study examples online and share your selections with those helping you practise. Your friends should read the materials before the practice sessions and play the role of the interviewer.

By conducting a practice session as if it were the real thing, your friends will help you work through the awkwardness and spontaneity of the case study interview and develop the confidence to perform successfully.

By following these tips, you’ll be ready to show off your analytical, communication and problem-solving skills, all important to the case study interview. However, don’t limit your preparation only to the guidance given for this specific style; rather, you’ll want to make sure you continue the things that served you well for other interview formats, including making a good first impression and avoiding interview faux pas .

By combining those behaviours with the preparation, mindset and practice needed to solve business problems on your feet, you’ll put yourself in a great position to succeed at a case study interview.

Secrets to a successful case-study interview

January 9, 2023

Prepping for (and maybe fretting) the case-study interview?

While this kind of interview may appear intimidating, consider this: The interviewer really wants you to do well.

So, shake off the nerves, relax and have fun.

Tips for standing out in the case-study interview: 

• Take your time; don't rush it.  Talk through the problem. If you can't make sense of it, take a moment and allow yourself some time to process what you've been missing. If you get stuck, get creative. Don't let yourself get bogged down; rely on your ingenuity. 
• Ask questions.  You can always ask your interviewer to define an acronym or to repeat or confirm details. If the interviewer asks, “How do we achieve success?”, don’t be afraid to ask, “What does ‘success’ mean to you? Is it turning a profit? Raising the company’s profile?” When you work on a client project, you need to ask questions to figure out what the problems might be, and the same applies here. The interviewer is your biggest asset in the room. They have the information you need to “solve the case” successfully. Use them wisely!
• Be flexible.  The focus of a case-study interview may vary. So, be prepared to participate in whatever discussion the interviewer has in mind. They may spend the first half of the interview asking about your previous experience, or they may dive right into the case study at the start. The bottom line: Be flexible, and be ready to discuss the work you do and how you do it.
• Use visual aids.  Don’t be afraid to use pen and paper, sketch out your thoughts, and talk through the problem at hand if it helps you get your ideas across. What matters most is demonstrating that you can solve problems.
• Focus on impact.  Inventory the information you have, and then dive in where you can have the most impact. Don’t forget to discuss your thought process and explain your assumptions.
• Tell a story.  Your experience has helped you progress in your career and education; use that experience. For example, in a business case study, you could bring your experience as a traveler to a case about a hypothetical airline. Your individuality is important. Your unique insights will serve you well when you’re interviewing.
• Pay attention to cues.  If the interviewer says something, it probably means something. Don’t dismiss seemingly extraneous details. For example, the interviewer might say, “The case is about a retailer who wants to increase the value of a company it purchased, and the owner loved the brand when growing up.” The purpose of that detail is to indicate that turning around and selling the asset is not an option for making it profitable, because the owner is attached to it.

Preparing for the job you want can take time, but it’s a worthwhile investment—especially when you receive an offer.

Your ideas, ingenuity and determination make a difference.

Case Interview: The Free Preparation Guide (2024)

The case interview is a challenging interview format that simulates the job of a management consultant , testing candidates across a wide range of problem-solving dimensions.

McKinsey, BCG and Bain – along with other top consulting firms – use the case interview because it’s a statistically proven predictor of how well a candidate will perform in the role. The format is not only used by management consulting firms. Other types of organizations – like tech companies, financial services institutions, and non-profits – often use case interviews to assess candidates who are interviewing for roles focused on shaping strategic initiatives.

If you’re preparing to face a case interview, you may be feeling a little apprehensive. The format is notoriously demanding and unlike any other type of recruitment assessment you may have experienced before. However, with the right preparation and investment of time and effort, it is possible to master.

In this guide, we break down everything you need to know about the case interview, outlining exactly what you need to do to prepare effectively and ace the case.

Key takeaways

• The classic case interview format follows the same steps that a management consultant would encounter on a client project. The interview is a little like a role-play where the interviewer plays the role of a client and the candidate plays the part of the consultant hired to solve the problem.
• Some firms occasionally deviate from the classic case interview format. Popular alternatives include written case studies – which require candidates to review paper documents and then prepare and deliver a presentation – and market sizing case interviews, which require candidates to estimate a number.
• Case interviews test candidates against a set of six problem-solving dimensions: structuring, math, judgment and insights, creativity, synthesis, and case leadership. The interviewer uses a scorecard to assess the candidate’s performance in each of these areas.
• Case interview questions can be about almost any type of challenge or opportunity. However, our research indicates that there are 10 types of questions that are asked most frequently at top consulting firms. These include questions on profit improvement, revenue growth, and market entry.
• To do well in a case interview, it’s vital to create custom interview structures that meet the conditions of the ‘AIM’ test. It helps to have a good working knowledge of key case interview frameworks, but this alone is not sufficient.
• A strong grasp of case math is also crucial when it comes to case interview performance. While only high-school level math skills are required, it’s an aspect of the case interview that many candidates find challenging.
• Successful candidates are able to summarize their findings effectively. They also demonstrate strong case leadership by progressing through the case proactively and remaining focused on its overarching objectives.
• To prepare for a case interview, it’s essential to learn every problem-solving skill that will be assessed. We teach all of these skills in our Interview Prep Course , which contains all the video lectures, sample interviews, case material, and practice tools you’ll need to ace any case interview.
• Most candidates who go on to receive an offer from a top consulting firm like McKinsey, BCG or Bain complete at least 25 live practice sessions with a partner before their interview. You’ll find over 100 high-quality cases in our Case Library and a diverse community of candidates available for practice in our Practice Room .
• Some candidates choose to supplement their preparation by working with a coach who has been an interviewer at a top consulting firm. Here at CaseCoach, our coaches have all been handpicked from the alumni of top firms such as McKinsey, BCG and Bain.
• Although the world’s top consulting firms all test candidates using similar methods, none of them approach the interview process in exactly the same way. If you’re preparing to interview at a top consulting firm, it’s important to do your research and find out what you can expect.

An introduction to the case interview

The case interview format, the classic case interview.

The vast majority of case interviews follow the same steps that management consultants encounter on real client projects.

• Brief: The interviewer gives the candidate a brief for the case. They explain the context in which the client is operating, and outline the challenge they’re facing.
• Clarification: The candidate then has the chance to ask clarifying questions. They might do this to ensure they’ve understood the context of the problem correctly or to confirm the client’s goals.
• Reflection: The candidate takes 60 to 90 seconds or so to reflect and lay out a structured approach to solving the case.
• Analysis: The candidate and interviewer then work through the case together, carrying out analyses and moving toward a recommendation. This is the part of the case where you’ll be handling numerical questions, reviewing exhibits, coming up with creative ideas, and so on. It comprises the vast majority of the time you’ll spend on the case.
• Synthesis: The case concludes with the candidate synthesizing their findings and making an overall recommendation to the client.

So what does this unique interview format look and feel like? In reality, a consulting case interview is a little like a role-play. The interviewer plays the role of a manager or client, and the candidate plays the part of the consultant hired to solve the problem. However, a case interview shouldn’t feel like a performance. The most successful candidates treat it as a natural conversation between two professional people.

In the video below you can see an example of exceptional case interview performance in action. The candidate and interviewer in the video are both former McKinsey interviewers.

Interviewer-led vs candidate-led cases

Although the classic case interview has an established format and assesses a specific set of skills, cases can be delivered in different ways. Some are more candidate-led, while others are more interviewer-led

In a candidate-led case, the candidate is in the driver’s seat and is free to explore different aspects of the problem. Interviewers don’t tell candidates what to focus on next. Instead, they provide additional information – like an exhibit or a new fact – when asked. The candidate then analyzes the information and suggests next steps to get to the answer.

In an interviewer-led case, the interviewer may interrupt the candidate and ask them to either perform a specific investigation or focus on a different aspect of the problem. This doesn’t mean the interview is going badly; the interviewer is simply following a script. As a result, in an interviewer-led case, candidates are less likely to take the wrong path.

It’s difficult to predict which style of case you’ll receive. Some firms are known for using one style of interview more frequently than another. However, in practice, most interviews fall somewhere between the two extremes, depending on the style of the interviewer and the case material they’re using. You should therefore always be ready to suggest next steps and have a view about how to get to the answer.

Other case interview formats

While the classic case interview is most common, there are a couple of other interview formats that top consulting firms use from time to time:

The written case study

Some management consulting firms use written case studies to simulate the experience of carrying out consulting work even more accurately than the classic, verbal case interview. In some locations, BCG and Bain have been known to adopt this approach for a small minority of candidates.

In written cases, candidates review a series of paper documents and then structure the problem, run some numbers, generate ideas and, finally, deliver a short presentation. You can learn more in our article on how to crack written case studies .

Market sizing case interviews

Management consulting firms and other employers sometimes use market sizing questions – also known as estimation questions – as a standalone interview format to assess candidates on a wide range of problem-solving dimensions.

In a market sizing interview, you’ll be asked to estimate a number. This might be something like the revenue of a sandwich store or how many ATMs there are in a certain city. The ability to size a market is also a skill required for solving many case interview questions. You can learn more in our article on how to nail market sizing case interviews .

Some key differences to expect

While case interviews are highly codified, it’s important to remember that every interview is unique.

In the final round of interviews, for example, cases may feel less scripted than they did in the first stage. Partners – who are part of the interviewing group in the final round – often use the same case for years at a time. This means they can deliver it without a script and, as a result, tend to give candidates more room to take the lead. You can learn more in our article on the differences between a first and final-round interview at McKinsey, BCG and Bain .

In addition, each firm or office might bring their own nuance or style to the classic case interview format. It’s important to do your research and find out what you can expect from the interview experience at your target firm or office. You can learn more in our article on how the interviews at McKinsey, BCG and Bain differ .

The skills assessed in case interviews

Case interviews are primarily about testing a set of problem-solving skills. The interviewer uses a scorecard to assess a candidate’s performance in the following dimensions:

• Structuring: This is the ability to break problems down into logical drivers. It’s most obviously required at the beginning of a case, where you can pause and take a moment to come up with an approach. But it’s also tested each time you have to consider a new aspect of the problem.
• Math: Most cases contain a quantitative component, such as estimation questions, break-even questions, or other calculations. To do well in this dimension, you need to lay out a clear and efficient approach, run calculations quickly and accurately, and then state their implications for the case.
• Judgment and insights: This dimension is about extracting insights from data, usually by interpreting information in a chart. Performing well in this area involves processing new information quickly, prioritizing what’s important, and connecting your findings to develop sound recommendations.
• Creativity: Cases often have a creative thinking component. Sharing numerous, varied and sound ideas – ideally in a structured way – can help you succeed here.
• Synthesis: This is all about wrapping up the case with a clear and practical recommendation, and delivering it convincingly.
• Case leadership: This dimension is about progressing through the case efficiently and staying focused on its objectives. Case leadership involves gathering facts effectively and building on new findings to develop a recommendation. It’s a particularly important dimension in candidate-led cases.

Questions to expect

If you’re preparing to interview at a top management consulting firm like McKinsey, BCG or Bain, you’re probably curious about the kind of case interview questions you can expect to receive.

To identify the most common case interview questions , we surveyed CaseCoach users who interviewed at either McKinsey, BCG or Bain for a generalist role in 2023. We found that of the 260+ case interviews reported by respondents:

• 20% focused on profit improvement
• 15% focused on revenue growth
• 12% focused on market entry
• 10% focused on cost cutting
• 9% focused on process optimization

These topics align with the typical challenges and opportunities faced by CEOs. Because the job of a management consultant is to help CEOs find solutions to these problems, it’s vital for candidates to demonstrate that they understand the issues behind these questions.

However, while there are some recurring topics, the context and nuances of each individual case mean that no two case questions are the same. Increasingly, firms are testing candidates on questions that fall outside of these recurring topics. One way they’re doing this is by focusing on non-traditional areas, like the public sector. If you’re interviewing for a generalist management consulting role, it’s therefore important to be ready for almost any type of case question.

If you’re interviewing for a role that’s focused on a specific industry or function, like financial services , you’ll likely be given a case focused on that particular area.

How to ace the case

Case interviews require you to think on your feet to solve a complex problem that you’ve never seen before, while being assessed against a number of problem-solving dimensions. Here’s what you need to do to rise to the challenge and ace the case:

1. Create case interview structures that meet the AIM test

Of all the case interview assessment dimensions, structuring is perhaps the most challenging, particularly for those who are just starting out. It requires candidates to propose a prioritized and insightful approach to the case that’s composed of a comprehensive set of independent drivers. Structuring plays a foundational role in the interview, setting the course for the entire conversation.

So, what does good case structuring look like? An effective structure should meet the conditions of the ‘AIM’ test. ‘AIM’ stands for:

• Answer-focused: The structure should identify the client’s goal and the question to solve. It should also provide an approach to answering that question.
• Insightful: The structure should be tailored to the specifics of the client or to the problem in question. You shouldn’t be able to apply it to another case of the same type.
• MECE: This is a well-known acronym among consultants. It stands for ‘mutually exclusive and collectively exhaustive’. In plain English, if a structure is ‘MECE’ it has been broken down into an exhaustive set of independent drivers.

2. Know key case interview frameworks

In a case interview, you’ll be asked to structure a variety of problems. There are a number of frameworks that can help you do this, whether the problem you’re structuring corresponds to a common case question or a different topic entirely:

Business frameworks

You can use established business frameworks to craft custom structures for the most common types of case questions. These include frameworks for mastering profitability questions , answering revenue growth questions and nailing market sizing questions .

Academic frameworks

For unusual case questions that don’t relate to an obvious business framework, it can be helpful to draw on an academic framework like supply and demand, ‘the three Cs’, or Porter’s Five Forces. You can learn more about all of these in our ultimate guide to case interview frameworks . The article includes other business and academic frameworks that you can use to craft custom structures for case questions.

Logical frameworks

Finally, logical frameworks can help you look at the big picture in order to structure your approach. These options can be particularly useful when you’re faced with an unusual case question that doesn’t lend itself to a business or academic framework. Some examples of logical frameworks include:

• Structuring with equations: This approach is most helpful for quantitative case questions. Listen out for introductions that focus on a number. These cases can often be broken down into an equation and then structured along its variables.
• Structuring based on hypotheses: This approach is most helpful for structuring qualitative cases. It involves laying out what you most need to believe in order to validate a specific recommendation. These beliefs form your set of key hypotheses, which you then test as you progress through the case.
• Structuring with root causes: This approach works well for structuring cases that require identifying the reasons for a problem. It involves laying out its potential causes in a way that is mutually exclusive and collectively exhaustive (i.e. MECE).

How to apply these frameworks

While business, academic, and logical frameworks can be helpful when it comes to structuring a problem, learning how to use them correctly is a skill in itself. Simply applying a framework to a case interview question in a ‘cookie-cutter’ fashion is not enough. To impress your interviewer and pass the AIM test, your structure will need to be heavily tailored to the situation at hand. In fact, many case questions can be best answered by combining different frameworks.

Ultimately, interviewers want to understand how your mind works and see you think on your feet. You’ll therefore need to demonstrate that you can propose a custom case interview structure to any question.

3. Be comfortable with simple math

Management consulting firms expect you to navigate mathematical problems confidently and reliably in case interviews. Regardless of your academic background or past experience, you’ll need to be able to set an approach to solve the problem, perform calculations quickly and accurately, and state the implications of your solution.

The good news is that you’ll only be required to demonstrate a high-school level of math skills in case interviews. However, with no calculators allowed and an interviewer looking over your shoulder, it’s natural to find this aspect of the experience a little intimidating.

So, what can you expect from case math? The problems you’ll be asked to solve may take the form of straight calculations, exhibits that require calculations, word problems, and estimation questions.

To do well in this part of the case interview, you’ll need to have a strong understanding of:

• The four operations: addition, subtraction, multiplication, and division
• Key math concepts such as fractions, percentages, and weighted averages
• Business math concepts such as income statements, investments, and valuations

To stand out to your interviewer, you’ll also need to work through math problems confidently and efficiently. Here are our top tips for doing this:

• Keep track of zeros: Case questions often involve large numbers, sometimes in the millions or even billions. Keeping close track of your zeros is therefore crucial. We recommend either counting the zeros in your calculation, using scientific notation, or assigning letter units to zeros.
• Simplify your calculations: This will help you work through problems quickly and efficiently while reducing the potential for mistakes. One way of simplifying calculations is by rounding numbers up or down to make them more ‘friendly’.
• Memorize frequently-used fractions: Some fraction values are used so frequently in case math that knowing them – along with their percentage value and decimal conversions – can save you significant time. We recommend memorizing the fraction and corresponding percentage and decimal values of 1/2, 1/3, all the way through to 1/10.

You can learn more in our guide to mastering case interview math .

4. Summarize your findings

Synthesis is a key skill assessed by interviewers, predominantly at the end of a case interview. You need to provide a clear and sound recommendation that answers the overall question convincingly. You must also describe the key supporting points that informed your recommendation and then outline any further steps you would advise the client to take.

When it comes to concluding cases effectively, this four-step framework can be extremely helpful:

• Quickly play the case question back to your interviewer.
• Answer the question directly and briefly by distilling your response into a single sentence, if possible.
• List the points that support your conclusion.
• Outline the next steps that you recommend to the client.

You can learn more in our article on how to conclude a case study interview .

5. Bring it all together with strong case leadership

Case leadership, more than any other dimension, will give your interviewer an indication of how independently you could handle your workstream as a consultant. It’s a particularly important skill in candidate-led cases, where you’ll set the course of the discussion without the interviewer steering you in a particular direction.

Demonstrating strong case leadership means progressing the case efficiently and staying focused on its overarching objectives. Using a ‘tracker page’ to capture your structure and organize your notes throughout the case will help you in this regard.

Another aspect of case leadership is gathering facts effectively. This includes making reasonable assumptions, requesting missing information, and asking probing questions.

Finally, you’ll be expected to build on new findings to develop your recommendation, adapt your approach, and suggest next steps.

Effective case leadership is all about showing your interviewer that you have a strong command of the problem-solving process. After investigating each key driver in your structure, you need to be able to articulate where you are in your overall approach to solving the problem, and what the next steps should be.

To do this, we recommend using a five-step process to handle every kind of analysis you conduct during the case, whether you’re responding to a numerical question, the data in an exhibit, or something else.

Here’s what that five-step process looks like:

• Set your approach. Define what you’re going to do upfront. It’s particularly important to be explicit here, especially if the analysis is in any way complex or ambiguous.
• Conduct your analysis. Your approach here will vary according to the kind of question you’re working through.
• State your findings. You may also want to make a note of your findings on your tracker page.
• State the implications of your findings. Explain how they impact both your answer to the question and the client’s broader goal.
• Suggest next steps. Your findings will sometimes change how you want to approach the rest of the case. This may mean altering your initial structure and editing it on your tracker page.

6. Be your best on the day

When the day of your interview comes around, you’ll want to be at your very best. But what exactly does this mean?

First, you should present yourself in a professional manner. It goes without saying that you should arrive on time but, ideally, you should plan to arrive early. You should also come equipped with the right material: a pen, squared A4 or letter-size paper pad, and copies of your resume. It’s also vital to dress appropriately for the occasion. Usually, this means wearing formal business dress, but this means different attires in different locations. We recommend doing some research to find out what consultants wear at your target firm and office.

To be at your best on the day of your interview, you must be well rested. Sadly, tiredness is one of the most common reasons for underperformance in consulting interviews. The day before is not the time to cram in further preparation. Instead, aim to have a quiet day and to get plenty of sleep at night.

Ultimately, consulting firms want to hire people who can represent the firm and interact with clients at every level, from the shop floor to the C-suite. Successful candidates treat the case interview as an opportunity to play the role of a management consultant advising a client (i.e. the interviewer). This means exhibiting a great deal of confidence and credibility, together with effective communication and an engaging attitude. It’s vital to stay focused on the overall problem and to drive the resolution of the case while being receptive to the interviewer’s input.

There are a lot of balls to juggle in a case interview, with the added pressure of a potentially life-changing outcome, but successful candidates don’t let their nerves get the better of them. We’ve provided some helpful hints and tips in our article on handling the stress of consulting interviews .

Being your best on the day of your interview requires extensive preparation. It means mastering each dimension of the case interview scorecard to the extent that the skills become second nature to you. It also means completing sufficient case practice to be able to focus on the big picture of the case you’re solving, rather than on simply demonstrating a set of skills.

How to prepare for case interview success

Delivering a standard of performance worthy of an offer from a top firm requires extensive case interview prep. In our experience, most successful candidates invest around 60 hours – or 10 hours each week over a six-week period – in their preparation. Failing to put this effort in is among the most common reasons why many candidates are unsuccessful.

Here’s what effective case interview preparation involves:

Learning the skills

In a case interview, your performance is assessed against a set of common problem-solving dimensions. To recap, these are structuring, math, judgment and insights, creativity, synthesis, and case leadership. It’s important to:

• gain a precise understanding of the expectations on each of these skills
• learn the techniques that will allow you to meet these expectations
• practice until your performance meets the required standard

We teach all these skills in our Interview Prep Course . In our bite-sized video lectures, we map out each of the key skills assessed in a case, and explain what you need to know to demonstrate each skill. We also share our tips on how to improve in each dimension, going above and beyond the advice we’ve included in this article.

In addition, our Interview Prep Course includes many more sample interviews that show real candidates – who went on to join top consulting firms – solving cases. Former consulting interviewers explain what the candidates did well on each dimension and where they could have improved.

Math is a critical prerequisite to handling cases and is something you should be comfortable with before you begin practicing. Our Case Math Course – provided as part of the Interview Prep Course – will help you brush up your skills. It contains 21 video lectures that cover everything you need to know, including the four operations, key math concepts, our pro tips, and business math.

After watching all our Interview Prep and Case Math video lectures, we recommend heading to the ‘Drills’ area of CaseCoach, where you can start practicing specific skills. Drills are interactive exercises that pose rapid-fire questions and provide instant feedback. They help you build your skills and confidence in specific case dimensions quickly, allowing you to make the most of your live case practice with partners. Our Interview Prep Course includes a comprehensive set of drills in four key areas: structuring, calculation, case math and chart interpretation.

When it comes to succeeding in a case interview, nothing beats live practice with a partner. Most candidates who go on to receive an offer from a top consulting firm like McKinsey, BCG or Bain complete at least 25 live practice sessions before their interview.

To practice live cases with a partner, you’ll need access to both case material and practice partners. In our Case Library , you’ll find over 100 cases – complete with solutions – developed by former management consultants. You can download eight of these cases right away by creating a free CaseCoach account. You’ll find a diverse community of fellow candidates who are all available for case interview practice in our Practice Room , where we facilitate over 3,000 practice sessions a week.

You can learn more in our article on how to practice case interviews .

Working with a coach

Some candidates choose to supplement their preparations by working with a consulting interview coach who has been an interviewer at a top firm.

These coaches have the skills and experience to gauge your level of performance and help you identify your areas of strength and weakness. They can also provide you with accurate and helpful feedback on your case-solving skills. This insight can help you accelerate your preparation and improve your performance. Getting used to interviewing with a professional should also help to reduce the stress of the consulting interview experience.

Here at CaseCoach, our coaches are all former consultants and interviewers who have been handpicked from the alumni of top firms such as McKinsey, BCG and Bain.

Do your research

Although employers who use case interviews all test candidates using similar methods, none of them approach the interview process in exactly the same way.

For instance, if you expect to interview with McKinsey, Bain or BCG, it’s helpful to know that these firms all give cases of similar complexity. However, there are some key differences. For example:

• Bain has been known to use estimation questions, such as market sizing, in interviews for its most junior (i.e. Associate Consultant level) roles.
• BCG and Bain occasionally use written cases.
• When it comes to the ‘fit’ interview, McKinsey uses its Personal Experience Interview format, while most Bain offices now use a ‘behavioral interview’ . Only BCG consistently uses the classic fit interview format .

Other differences include the number of rounds of interviews each firm conducts, and their preference for using interviewer-led or candidate-led cases. Wherever you interview, it’s vital to do your research and find out what you might be able to expect.

When it comes to getting ready for the case interview, knowing what you will be assessed on, learning how to succeed, and having access to the best practice resources can all go a long way. Now, you need to put in the hard work and prepare! Good luck.

What is a case interview?

Case interviews are a special type of interview that every single consulting firm uses. They are almost exclusively used by consulting firms, although some companies with ex- consultants may also use them.

A case interview, also known as a “case” for short, is a 30 to 60-minute exercise in which you and the interviewer work together to develop a recommendation or answer to a business problem.

These business problems can be anything that real companies face:

• How can Amazon increase its profitability?
• What can Apple do to increase customer retention?
• How should Tesla price its new electric vehicle?
• Where should Disney open another Disneyland theme park?

Case interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that consulting firms solve for their clients. Many case interviews are based on actual projects that interviewers have worked on.

While consulting projects typically last between 3 to 9 months, case interviews condense solving the business problem into just 30 to 45 minutes.

Case interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.

They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.

Although case interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed.

Unless you are interviewing for a consulting firm that specializes in a particular industry or function, cases are designed to be solved by someone that has general business knowledge.

Nailing your case interviews is critical to getting  into consulting . There is no way to get a consulting job offer without passing your case interviews.

What are examples of a case interview?

Here is an example of what a perfectly solved case interview looks like:

Here is another example of what a case interview looks like. This case interview is one where the interviewer leads most of the interview.

Here is a third example of a case interview. In this case interview, the candidate leads most of the interview. We’ll cover the difference between interviewer-led and candidate-led case interviews later in the article.

Finally, here is a fourth example of what a case interview looks like. This case is primarily focused on market sizing. We’ll cover what market sizing is and how to solve it later in the article.

Why are case interviews used?

Case interviews are the best way for consulting firms to predict which candidates will make the best consultants. Case interviews do not predict this perfectly, but they come quite close.

Since case interviews simulate the consulting job by placing you in a hypothetical business situation, interviewers use case interviews to see how you would perform as a hypothetical consultant.

Many of the skills and qualities needed to successfully complete a case interview are the same skills and qualities needed to successfully finish a consulting case project.

Case interviews also give you a sense of whether you would like the consulting job. If you find case interviews interesting and exciting, you’ll likely enjoy consulting. If you find case interviews dull and boring, consulting may not be the best profession for you.

What do case interviews assess?

Case interviews assess five different qualities or characteristics: logical and structured thinking, analytical problem solving, business acumen, communication skills, and personality and cultural fit.

1. Logical and structured thinking : Consultants need to be organized and methodical in order to work efficiently.

• Can you structure complex problems in a clear, simple way?
• Can you take tremendous amounts of information and data and identify the most important points?
• Can you use logic and reason to make appropriate conclusions?

2. Analytical problem solving : Consultants work with a tremendous amount of data and information in order to develop recommendations to complex problems.

• Can you read and interpret data well?
• Can you perform math computations smoothly and accurately?
• Can you conduct the right analyses to draw the right conclusions?

3. Business acumen : A strong business instinct helps consultants make the right decisions and develop the right recommendations.

• Do you have a basic understanding of fundamental business concepts?
• Do your conclusions and recommendations make sense from a business perspective?

4. Communication skills : Consultants need strong communication skills to collaborate with teammates and clients effectively.

• Can you communicate in a clear, concise way?
• Are you articulate in what you are saying?

5. Personality and cultural fit : Consultants spend a lot of time working closely in small teams. Having a personality and attitude that fits with the team makes the whole team work better together.

• Are you coachable and easy to work with?
• Are you pleasant to be around?

All of these five qualities can be assessed in just a 30 to 60-minute case interview. This is what makes case interviews so effective in assessing consulting candidates.

What companies give case interviews?

Case interviews are primarily used by management consulting firms (e.g., McKinsey, BCG, and Bain), but they are also used by some technology companies (e.g., Meta, Google) and private equity firms (e.g., KKR, Blackstone) that have a lot of ex-consultants.

Management consulting firms that give case interviews

• EY-Parthenon
• PwC and Strategy&
• Roland Berger
• Oliver Wyman

Technology companies that give case interviews

• Microsoft (including LinkedIn)
• Capital One

Private equity firms that give case interviews

• The Blackstone Group
• Bain Capital

When are case interviews given?

Case interviews are given in nearly every single round of interviews. During first round consulting interviews expect 1-2 case interviews. During final round consulting interviews , expect another 2-4 case interviews.

The only round of interviews that will not have a case interview is the initial phone screen with a recruiter. They will ask primarily resume and behavioral interview questions.

First round interviews are heavily focused on case interviews. There will typically be few behavioral or fit interview questions asked. Each case interview is typically 30 to 40 minutes each. Behavioral or fit interview questions may take up less than 10 minutes.

Final round interviews have a bit more focus on behavioral and fit interview questions, but the vast majority of time is still spent on case interviews. Each case interview is typically 40 to 60 minutes each. Behavioral or fit interview questions may take up to 40 minutes.

As you can see, case interviews are the primary way that management consulting firms assess and select candidates.

There are seven key components or steps of a case interview: understanding the case background, asking clarifying questions, structuring a framework, kicking off the case, solving quantitative problems, answering qualitative questions, and delivering a recommendation.

1. Understanding the case background

The case interview will begin with the interviewer giving you the case background information. Let’s say that the interviewer reads you the following:

Interviewer: Our client, Coca-Cola, is a large manufacturer and retailer of non-alcoholic beverages, such as sodas, juices, sports drinks, and teas. They have annual revenues of roughly $30 billion and an operating margin of roughly 30%. Coca-Cola is looking to grow and is considering entering the beer market in the United States. Should they enter?

As the interviewer reads this, take notes. It is important to understand what the objective of the case is and keep track of information.

One strategy for taking notes effectively is to turn your paper landscape and draw a vertical line to divide your paper into two sections. The first section should be roughly two-thirds of the page while the second section will be one-third of the page.

Take notes in the second section of your page:

After the interviewer finishes giving the case background information, confirm that you understand the situation and objective. Provide a concise synthesis like the following:

You: To make sure I understand correctly, our client, Coca-Cola, is a large manufacturer and retailer of non-alcoholic beverages. They are looking to grow and our objective is to determine whether or not they should enter the U.S. beer market.

Interviewer: That sounds right.

Make sure your synthesis is concise. You do not want to regurgitate verbatim everything that the interviewer has said. Only mention the most important pieces of information.

You should also make sure you verify the objective of the case. Answering or solving the wrong case objective is the quickest way to fail a case interview.

2. Asking clarifying questions

Next in the case interview, you’ll have the opportunity to ask questions before you begin thinking about how to solve the case.

At this point, only ask questions that are critical for you to fully understand the case background and objective. You’ll be able to ask more questions later.

Types of questions you should ask:

• Asking for a definition of a term you’re unfamiliar with
• Asking for information that strengthens your understanding of the company or situation
• Asking questions that clarify the objective of the case
• Asking to repeat information you may have missed

You might ask a few questions like the following:

You: Is Coca-Cola looking to specifically grow revenues or profits?

Interviewer: Coca-Cola wants to grow profits.

You: Is there a particular financial goal or metric Coca-Cola is trying to reach within a certain time frame?

Interviewer: They are looking to grow annual profits by $2 billion within 5 years.

You: Great. Those are all the immediate questions I have for now.

3. Structuring a framework

After you understand the case background and objective of the case interview, lay out a framework of what areas you want to look into in order to answer or solve the case.

A case interview framework is simply a tool that helps you structure and break down complex problems into simpler, smaller components. Think of a framework as brainstorming different ideas and organizing them into different categories.

When creating a framework, it is completely acceptable to ask the interviewer for a few minutes of silence to write out a framework.

You: Would you mind if I take a few minutes to structure my thoughts and develop a framework to tackle this case?

Interviewer: Of course, go ahead.

For this case example, what do you need to know in order to help Coca-Cola decide whether or not they should enter the beer market?

You might brainstorm the following questions:

• Does Coca-Cola know how to produce beer?
• Would people buy beer made by Coca-Cola?
• Where would Coca Cola sell its beer?
• How much would it cost to enter the beer market?
• Will Coca-Cola be profitable from doing this?
• How can Coca-Cola outcompete competitors?
• What is the market size of the beer market?

This is not a very structured way of tackling the case, so organize these ideas into a framework that has 3 – 4 broad areas, also called “buckets”, that you want to investigate.

An easy way to develop these buckets is to ask yourself, what 3 – 4 things must be true for you to 100% recommend that Coca-Cola should enter the beer market.

In an ideal world. These four things would need to be true:

• The beer market is an attractive market with high profit margins
• Competitors are weak and Coca-Cola will be able to capture significant market share
• Coca-Cola has the capabilities to produce an outstanding beer product
• Coca-Cola will be extremely profitable

You can rephrase these points to be the broad categories in your framework. You can write your framework in the first section of your paper:

Next, let’s add a few bullets under each category to give more detail on exactly what information we need to know to decide whether Coca-Cola should enter the beer market.

This entire process of brainstorming ideas and developing a structured framework should only take a few minutes.

How do you come up with a framework so quickly?

Most candidates make the mistake of either using a single memorized framework for every case or memorizing multiple different frameworks for different cases.

The issue with memorized frameworks is that they aren’t tailored to the specific case you are solving for. When given an atypical business problem, your framework elements will not be entirely relevant.

Interviewers can easily tell that you are regurgitating memorized information and not thinking critically.

Instead of memorizing frameworks, I recommend memorizing a list of 8 - 10 broad business elements, such as the following:

When given a case, mentally run through this list and pick the 3-4 elements that are most relevant to the case. This will be your framework. If the list does not give you enough elements, brainstorm and add your own elements to your framework.

This strategy guarantees that your framework elements are relevant to the case. It also demonstrates that you can create unique, tailored frameworks for every business problem.

Using this strategy for this case, you would run through your list of memorized business elements and select the following:

This strategy is a shortcut for creating unique tailored frameworks for every business problem. You do not need to develop a framework entirely from scratch every time.

Now that you have your framework, turn your paper to face the interviewer and walk them through it.

You: To decide whether or not Coca-Cola should enter the market, I want to look into four main areas.

One, I want to look into the beer market attractiveness. Is this an attractive market to enter? I’d want to look into areas such as the market size, growth rate, and profit margins.

Two, I want to look into the beer competitive landscape. Is this market competitive, and will Coca-Cola be able to capture meaningful market share? I want to look into questions such as the number of competitors, how much market share each competitor has, and whether competitors have any competitive advantages.

Three, I want to look into Coca-Cola’s capabilities. Do they have the capabilities to succeed in the beer market? I want to look into things such as whether they have the expertise to produce beer, whether they have the distribution channels to sell beer, and whether there are any existing synergies they can leverage.

Four, I want to look into expected profitability. Will Coca-Cola be profitable from entering the beer market? I want to look into areas such as expected revenues, expected costs, and how long it would take to break even.

The interviewer might ask a few questions on your framework, but will otherwise indicate whether they agree or disagree with your approach.

For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .

4. Kicking off the case

If this is an interviewer-led case, the interviewer will propose which area of your framework they would like to dive deeper into. They might say something like the following:

Interviewer: Your framework makes sense to me. Why don’t we start by estimating the size of the U.S. beer market.

If this is a candidate-led case, you will be expected to propose an area to look into. There is no right or wrong area to start first. Propose any area of your framework as long as you have a reason for it.

You could say something like:

You: To start, I’d like to look into the beer market attractiveness. I’d like to first understand the market size to determine if the beer market is an attractive market.

If you end up picking an area that the interviewer does not want you to explore, they will redirect you to an area that they do want you to explore.

The two styles of case interviews are nearly identical. The only difference is whether or not you have to proactively propose what area to explore first and what area you want to explore next.

5. Solving quantitative problems

Expect to perform calculations and analyze charts and graphs during your case interview.

Market sizing questions are one type of quantitative question you may get asked.

Let’s say the interviewer asks you:

Interviewer: What is the market size of beer in the U.S.?

Most candidates jump right into the math, stating the U.S. population and then performing various calculations. Doing math without laying out a structure often leads to making unnecessary calculations or reaching a dead-end.

Laying out an upfront approach helps avoid these mistakes and demonstrates that you are a logical, structured thinker.

For this market sizing problem, you could structure your approach in the following way:

• Start with the U.S. population
• Estimate the percentage that are legally allowed to drink alcohol
• Estimate the percentage that drink beer
• Estimate the frequency in which people drink beer
• Estimate the average price per can or bottle of beer

Multiplying these steps together gives you the answer. By laying out an approach up front, the interviewer can easily understand how you are thinking about the problem. With the right structure, the rest of the problem is simple arithmetic.

Sometimes the interviewer will give you numbers to use for these calculations. Other times, you’ll be expected to make assumptions or estimates.

When performing your calculations, make sure to do them on a separate sheet of paper. Calculations often get messy and you want to keep your original paper clean and organized.

A sample answer to this question could look like this:

You: To estimate the market size of beer in the U.S., I’m going to start with the U.S. population. Then, I’ll estimate the percentage that are eligible to drink alcohol. I’ll then estimate the percentage of the remaining population that drinks beer.

If we take this and multiply it by the frequency in which people drink beer and the average price per can or bottle of beer, we will find an estimate for the market size. 

Does this approach make sense to you?

Interviewer: Makes sense to me.

You: Great. I’ll assume the U.S. population is 320M people. Assuming the average life expectancy is 80 years old and an even distribution of ages, roughly 75% of the population can legally drink alcohol.

This gives us 240M people. Of these, let’s assume 75% of people drink beer. That gives us 180M beer drinkers.

Let’s say on average, a person drinks five beers a week, or roughly 250 beers per year, assuming roughly 50 weeks per year.

This gives us 180M * 250 = 45B cans or bottles of beer.

Assuming the average can or bottle of beer costs $2, this gives a market size of $90B.

You should not only answer the question, but tie the answer to the case objective.

In other words, how does knowing the U.S. market size of beer help you decide whether or not Coca-Cola should enter the market?

You could say something like the following:

You: Given that Coca-Cola has annual revenues of $30B, a $90B beer market represents a massive opportunity. The market size makes the beer market look attractive, but I’d like to understand if beer margins are typically high and determine how much market share Coca-Cola could realistically capture.

A second type of quantitative question you could be asked is to calculate profit or profitability. The interviewer may ask you:

Interviewer: Assume that a 12-ounce can of beer sells for $2 on average. To produce a keg of beer, it costs $100 for raw materials, $95 for labor, and $75 for storage. If a keg of beer holds 1,800 oz. of beer, what is the profit margin for beer?

Make sure you structure your approach and connect your answer to the case objective.

A sample answer could look like:

You: To calculate the profit margin for beer, I will first calculate the total costs to produce a keg of beer. Next, I will divide the volume of a keg by the volume of a can to determine how many cans a keg of beer produces.

Afterwards, I will divide the total cost of producing a keg of beer by the number of cans in a keg of beer to determine the cost per can.

Finally, I can use the price and cost per can of beer to calculate the margin of beer. Does this approach make sense to you?

You: Great. The total cost of a keg of beer is $100 plus $95 plus $75, or $270. The number of cans of beer in a keg is 1,800 oz. divided by 12 oz., or 150 cans.

Therefore, the cost per can of beer is $270 divided by 150 cans, or $1.80. Since the average price of beer is $2 per can, the profit is $0.20 per can. This makes the margin $0.20 divided by $2 or 10%.

Compared to Coca-Cola’s overall operating margin of 30%, the beer market profit margin of 10% is significantly lower. Although the market size for beer is large, the low margin makes the beer market less attractive.

A third type of quantitative question you could get asked is interpreting charts and graphs. The interviewer may show you the following:

A helpful strategy is to start your analysis by explaining what the axes of the chart show. This will help you understand the chart better.

Next, don’t just read what numbers the chart shows, but interpret what those numbers mean for the case objective.

A sample answer might look like the following:

You: For this chart, we have market share on the y-axis and different categories of beer on the x-axis. For each category, we see that market share is concentrated among a few large players. This implies a highly competitive market with high barriers to entry. Because of this, the beer market does not look attractive because it is so competitive.

6. Answering qualitative questions

In addition to asking quantitative questions during the case interview, the interviewer will also ask qualitative questions.

One type of qualitative question you could get asked are brainstorming questions. For example, the interviewer might ask:

Interviewer: What are the barriers to entry in the beer market?

Most candidates answer by listing ideas that immediately come to mind:

• Brewing equipment
• Beer production expertise
• Distribution channels

This is a highly unstructured way of answering the question. Make sure to use a simple structure to organize your thoughts.

A simple structure, such as thinking about barriers to entry as either economic barriers or non-economic barriers, helps facilitate brainstorming and demonstrates logic and structure.

With this structure, you might come up with the following answer:

Have a simple structure when answering qualitative questions. Examples of other simple structures to use include the following:

Additionally, take your answer and connect it to the case objective. In this example, are these barriers to entry high or low? Do you think Coca-Cola can overcome these obstacles to enter the beer market?

You might answer this question in the following way:

You: I’m thinking of barriers to entry as economic barriers and non-economic barriers. Economic barriers include things such as equipment, raw material, and other capital. Non-economic barriers include: beer brewing expertise, brand name, and distribution channels.

Looking at these barriers, I think it will take Coca-Cola a lot of work to overcome these barriers. While Coca-Cola does have a brand name and distribution channels, they lack beer brewing expertise and would have to buy a lot of expensive equipment and machinery. These barriers make entering the beer market difficult.

Another type of question you could get asked are business opinion questions, such as the following:

Interviewer: Do you think there are significant production synergies in producing non-alcoholic beverages and producing beer?

As always, structure your answer and connect your answer to the case objective.

Here is a sample answer:

You: Production involves equipment, raw materials, and labor. There is likely some overlap in equipment, such as using the same bottling machines, but Coca-Cola will likely need new equipment for brewing beer.

Raw materials, on the other hand, are completely different. Coca-Cola will need to source barley, hops, and yeast, which it currently does not use in its existing beverages.

Finally, the same labor can be used, but employees will need new training since producing beer is fairly different from producing a non-alcoholic drink.

Overall, I think there are only a few production synergies that Coca-Cola can leverage, which makes entering the market a bit more difficult.

7. Delivering a recommendation

You’ve done a ton of work so far in the case interview and now it is time to put everything together into a recommendation.

Throughout the interview, you should have been making notes of key takeaways after each question you answer.

Take a look at the key takeaways you’ve accumulated so far and decide whether you want to recommend entering the beer market or not entering the beer market:

• The U.S. beer market size is $90B compared to Coca-Cola’s annual revenue of $30B
• The beer market profit margins are 10% compared to Coca-Cola’s average margin of 30%
• The beer market is highly concentrated across all categories
• Barriers to entry are moderate
• There are some synergies with existing production

There is no right or wrong recommendation, as long as you support your recommendation with reasons and evidence.

Regardless of what stance you take, make sure you have a firm recommendation. You do not want to be flimsy and switch back and forth between recommending entering the market and not entering the market.

Secondly, make sure your recommendation is clear and concise. Use the following structure:

• Clearly state what your recommendation is
• Follow that with the 2 - 3 reasons that support your recommendation
• State what potential next steps would be to further validate your recommendation

The conclusion of the case might look like the following:

Interviewer: Let’s say that you bump into the CEO of Coca-Cola in the elevator. He asks you what your preliminary recommendation is. What do you say?

You: I recommend that Coca-Cola should not enter the U.S. beer market for the following three reasons.

One, although the market size is fairly large at $90B, the margins for beer are just 10%, significantly less than Coca-Cola’s overall operating margin of 30%.

Two, the beer market is very competitive. In all beer segments, market share is concentrated among a few players, which implies high barriers to entry. Coca-Cola lacks beer brewing expertise to produce a great product that existing incumbents have.

Three, there are not that many production synergies that Coca-Cola can leverage with its existing products. Coca-Cola would need to buy new equipment, source new raw materials, and provide new training to employees, which will be time-consuming and costly.

For next steps, I want to look into Coca-Cola’s annual expected profits if they were to enter the U.S. beer market. I hypothesize that they will be unable to achieve an increase in annual profits of $2B within five years, but I’d like to confirm this through further analysis.

What are the different types of case interviews?

Case interviews cover a wide variety of functions and business situations. However, there are six common case interview business situations that account for the majority of all case interviews: profitability, market entry, growth, pricing, merger and acquisition, and new product.

There is a very high chance that you’ll see these types of case interviews in your first-round and final-round consulting interviews.

1. Profitability case interviews

Profitability cases ask you to identify why a company is experiencing a decline in profitability and what they should do to address it. This is the most common business situation for case interviews.

To solve these types of cases, you’ll need to understand quantitatively, what is the driver causing the decline in profits? You will need to determine whether revenues have gone down, costs have gone up, or both have occurred.

Afterwards, you’ll need to understand why this is happening. Once you understand this, you can brainstorm potential ideas and prioritize the solutions that are the most impactful and feasible to implement.

2. Market entry case interviews

Market entry cases ask you to determine whether a company should enter a new market. This is the second most common business situation for case interviews.

To make this decision, you’ll need to assess whether the market is attractive, how strong competitors are, whether your company has the capabilities to enter, and what the expected profitability is.

3. Growth case interviews

Growth cases ask you to determine how a company can best increase its revenues.

To solve this case, you’ll need to identify all of the major ways the company can grow.

Should the company grow organically by targeting new geographies or customer segments?

Should they grow by launching new products and services?

Instead, should the company grow inorganically by acquiring or forming a partnership with another company?

Once you have identified all of the major opportunities for growth, you can prioritize the opportunities that are the most impactful and feasible.

4. Pricing case interviews

Pricing cases ask you to determine how to set the optimal price on a product or service. To do this, you’ll need to consider different factors.

How much does the product cost to produce? You don’t want to price the product too low such that you have a loss on each sale.

How much are customers willing to pay for the product? You don’t want to price the product too high such that no customer is willing to purchase your product.

How much are competitors setting prices for similar products? You don’t want to price the product too high such that customers choose to purchase competitor products.

Considering each of these points will help you determine the right price to set.

5. Merger and acquisition case interviews

Merger and acquisition cases ask you to determine whether a particular company should be acquired.

To solve this case, you’ll first need to understand what the reason is for the acquisition. In most cases, the company will be looking to grow its revenues and profits.

Then, you’ll need to assess whether the market that the acquisition target plays in is attractive, whether the acquisition target itself is attractive, whether there will be any meaningful synergies, and whether the financials of the acquisition make sense.

These considerations will help you determine whether the acquisition should be made.

6. New product case interviews

New product cases ask you to determine whether a company should create and launch a particular new product.

To solve this case, you’ll need to assess whether the product’s market is attractive, whether the product meets customer needs, whether the product is superior to competitor products, whether the company has the capabilities to create and launch the product, and what the expected profitability is.

These considerations will help you make a smart and informed decision.

W hat are the different formats of case interviews?

There are three major formats of case interviews: traditional case interviews, written case interviews which assess presentation and communication skills more heavily and group case interviews which assess teamwork and collaboration more heavily.

1. Traditional Case Interview

The traditional case interview is the format that accounts for 80 to 90 percent of all case interviews. It is the format we have covered so far in which you and the interviewer work together to develop a recommendation or answer to a business problem.

The traditional case interview starts with the interviewer explaining the case background information to you. The case interview ends after you have delivered your recommendation to the interviewer.

There are two styles of traditional case interviews, candidate-led case interviews and interviewer-led case interviews.

• Candidate-led case interviews : You will be driving the direction of the case. You will propose what area of your framework to start in, what questions you would want to answer, what analyses you would want to do, and what the next step is to solve the case. If you go down the wrong direction, the interviewer will steer you back on course, but you ultimately decide what to do next.
• Interviewer-led case interviews : The interviewer will be steering and controlling the direction of the case. The interviewer will point you to which questions to answer, what analyses to do, and what the next step is to solve the case.

2. Written Case Interview

Written case interviews are much less common than traditional case interviews.

For written case interviews, you will be given a packet of information at the beginning of the interview. This packet usually has between 20 to 40 pages of graphs, charts, tables, and notes. You’ll be given information on the case background and the objective of the case.

In some written case interviews, you may also be given a list of important questions to answer. In other written case interviews, you’ll only be given the primary business problem you are asked to answer.

You’ll then have 1 to 2 hours to analyze the information packet and then make 3 to 5 slides to present your analysis and recommendation to the interviewer.

In some written case interviews, you’ll have to create these slides completely from scratch. In other written case interviews, you’ll have pre-filled slide templates that you will fill out with your analysis and work.

For written case interviews, you’ll be working by yourself. The interviewer will leave the room to let you work and then return when time is up to hear your presentation. During the presentation, the interviewer may ask follow-up questions on your work and findings.

3. Group Case Interview

Group case interviews are also much less common than traditional case interviews.

For group case interviews, you’ll be put into a group of 3 to 6 people with other candidates that are also interviewing for the same consulting job you are interviewing for. The group will be given materials which contain the case background, objective, and all of the information needed to solve the case.

You’ll then have 1 to 2 hours to work together as a group to create a slide presentation that summarizes your work and recommendation.

During this time, the interviewer will be listening in on the discussions and conversations that the group will have, but they will not interfere or answer any questions.

Once the time is up, your group will deliver your presentation to the interviewer, who may also ask follow-up questions on the work and findings.

For group case interviews, there is a heavy emphasis on assessing how well you work in a team. Consultants spend almost all of their time working closely in small teams, so teamwork and collaboration are essential.

Interviewers will assess you on criteria such as the following:

• Can you make meaningful contributions while working in a group?
• Are you easy to work with?
• Can you handle conflict and disagreement with teammates?
• Do you bring out the best ideas and qualities in other people?

How long does it take to prepare for case interviews?

Candidates typically spend 60 to 80 hours preparing for case interviews, equivalent to 6 to 8 weeks of preparation. However, exceptional candidates with strong business and communication skills might need as little as 4 weeks. Those lacking a business background could require as long as 12 weeks.

We have seen exceptional candidates pass their consulting interviews and receive offers from McKinsey, BCG, or Bain in just one or two weeks. We have also heard of candidates spending more than 100 hours preparing for case interviews, but receiving no consulting offers.

There are four factors that impact how much time you’ll need to dedicate to preparing for case interviews. Assessing these factors will help you set expectations for the amount of time you should expect to spend.

1. Natural intuition and ability

Case interviews require a strong business intuition and excellent communication skills. Some people will have a higher baseline on these skills than others.

If you have studied business in school or have worked a job that does similar work to consulting, you’ll likely already have a good business intuition. If you give speeches, presentations, or participate in debates frequently, you’ll likely already have good communication skills.

Although these abilities can be learned by anyone, some people will naturally have strong abilities to start with. For these people, they will likely need to spend less time preparing for case interviews than the average person.

2. Learning speed

Some people are faster learners than others. There are many skills you’ll need to learn and develop to be proficient in case interviews, such as structuring a framework, developing a hypothesis, solving math problems , and delivering a recommendation.

These skills require no specialized knowledge or expertise. Anyone can learn and master these skills with enough practice. However, some people will pick up these skills faster than others.

3. Quality of practice

The quality of your practice determines how quickly you can learn and master case interviews.

If you practice with case interview partners that don’t know how to properly deliver a case interview and provide feedback, you’ll learn much more slowly than someone practicing with a consultant who has given interviews before.

Similarly, if the practice cases you use are not representative of an actual case interview or don’t have outstanding model answers, you’ll learn much more slowly than someone using high-quality practice cases.

4. Consulting firm requirements

The amount of time needed to prepare for case interviews also depends on the consulting firms that you are applying for.

The top three consulting firms, McKinsey, BCG, and Bain, have the highest standards and requirements when assessing a candidate’s case interview capabilities. Less prestigious consulting firms may have a lower bar that you need to pass.

If you are recruiting for McKinsey, BCG, and Bain, you’ll likely need to spend more time preparing for case interviews than someone recruiting for Deloitte or Accenture.

When should I begin preparing for case interviews?

Given that it takes candidates on average 60 to 80 hours to prepare for case interviews, you should begin preparing for case interviews at least 6 to 8 weeks in advance. To give yourself adequate time, you should ideally start preparing 16 to 24 weeks in advance.

Preparing 16 to 24 weeks in advance provides sufficient buffer time. You may find yourself too busy to prepare for case interviews during some weeks. You may also realize that you have significant skill or capability gaps as you start preparing, requiring more time to improve.

Preparing for case interviews more than 24 weeks in advance should not be necessary. 

Often times, candidates that start preparing too early will burn themselves out from having done too many practice cases. This often happens right before interviews begin, which leads to poor outcomes.

To avoid burning yourself out, start preparing for interviews ideally 16 to 24 weeks in advance and a minimum of 6 to 8 weeks in advance.

How do I prepare for case interviews?

There are seven steps to preparing for case interviews.

1. Understand what a case interview is

The first step in preparing for consulting case interviews is to understand exactly what case interviews are.

Case interviews are a special type of interview that every single consulting firm uses. They typically take 30 – 60 minutes and involve you working with the interviewer to solve a business problem and provide a recommendation.

When you are familiar with what case interviews are, it is important to know what a great case interview performance looks like.

Knowing what a great case interview performance looks like will facilitate how quickly you learn case interview strategies in the next step.

Before continuing onto the next step, you should be familiar with:

• The overall objective of a case interview
• The structure and flow of a case interview
• The types of questions you could get asked
• What a great case interview performance looks like

2. Learn the right strategies

Now that you have sufficient background knowledge, the next step in preparing for case interviews is to learn the right strategies to build good case interview habits.

It is much more effective to learn the right case strategies the first time than to learn poor strategies and try to correct them later.

The quickest, most efficient way to learn these strategies is to go through our Comprehensive Case Interview Course .

If you prefer reading case interview prep books instead, the three I recommend are:

• The Ultimate Case Interview Workbook
• Case Interview Secrets

Hacking the Case Interview provides strategies on exactly what to do and what to say in every step of the case interview. It is a concise and straight to the point guide. I recommend this book as the first book to read for beginners.

Case Interview Secrets teaches core concepts such as the issue tree , drill-down analysis, and a hypothesis driven approach. It illustrates these concepts through stories and anecdotes. If you have read Hacking the Case Interview, I recommend also reading this book to get perspectives from a second author. Check out our full review of Case Interview Secrets .

Case in Point provides a ton of specific and complex frameworks. However, you likely won’t be using many of these in an actual case interview because many of them are overly complex and specific. If you have time, it may be useful to skim through this book. Check out our full review of Case in Point .

At the bare minimum, read either the first or second book. If you have the time, read the first two books so that you can get strategies from two different authors.

Make sure to spend sufficient time learning the right strategies before starting to practice cases. It is ineffective to practice cases if you have no idea what strategies to practice and refine.

Before moving onto the next step, you should at least have strategies for the following parts of a case interview:

• Developing unique and tailored frameworks
• Solving quantitative problems
• Answering qualitative questions
• Delivering a recommendation

3. Practice 3-5 cases by yourself

Once you have learned the right strategies, the next step in case interview prep is to practice.

When practicing case interviews, it is usually better to practice with a case interview partner than to practice by yourself . Casing with a partner better simulates the real case interview experience.

However, when you are just starting to practice, I recommend doing the first 3 – 5 cases by yourself.

There are three reasons for this:

• You can get the hang of the case interview structure and format much more quickly working by yourself rather than having to wait to schedule a time with a partner
• There are many aspects of case interviews that you can practice without a partner, such as structuring a framework and solving quantitative problems. You can get much more practice working through these parts by yourself
• You may have difficulty finding a case interview partner if you are a complete beginner. Without having done any cases, you likely won’t know how to properly give a case or provide good feedback

4. Practice 5-10 cases with a partner

The next step in preparing for case interviews is to case with a partner.

Casing with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner.

When practicing cases with a partner, ensure you are spending enough time after cases to deliver feedback.

For a case that takes around 30 – 40 minutes, spend at least 15 – 20 minutes for feedback. Much of your learning and improvement will come from these feedback sessions.

Do not move onto the next step until you have done at least 5 – 10 cases and are beginning to feel comfortable with case interviews.

5. Practice with a former or current consultant

At this point, I highly recommend asking former or current consultants to give you a practice case. This will significantly help you prepare for case interviews.

Doing a mock case with a former or current consultant is highly advantageous because they know exactly how to run cases and give feedback. You’ll receive incredibly helpful feedback that your previous case partners likely missed.

If you feel that you are plateauing with your case partner, that is a sign you should do a mock case interview with a former or current consultant.

You can find former or current consultants among:

• People you met during the consulting recruiting process
• Your broader LinkedIn network

I would not ask a consultant that is involved with the consulting recruiting process for a case too prematurely. Although these practice cases are not evaluative, some firms will actually make note of how well you perform during the practice case.

At this point, you will have accumulated a long list of improvement areas from all of the different people you have cased with.

6. Work on your improvement areas

In this step of preparing for case interviews, you will work on strengthening and fine-tuning your improvement areas. Examples of common improvement areas include:

• Creating a more complete and mutually exclusive framework
• Performing math calculations quicker or more smoothly
• Providing more structure to your qualitative answers
• Leading the case more proactively
• Delivering a more succinct recommendation

Try to focus on improving one thing at a time. This is much more effective than trying to improve everything at once.

For some areas, such as math, it will be better to work independently. For other areas, such as learning to proactively lead the case, it will be better to work with a case partner.

If you are looking for more cases, look at the resources listed in step four. If you are looking for specific drills or practice problems for a particular part of a case interview, check out The Ultimate Case Interview Workbook .

Do not move onto the next step until you have finished working on all of your improvement areas.

7. Stay sharp

If you have progressed this far, congratulations! You have almost finished preparing for case interviews.

Once you feel that you have no more improvement areas to work on, the key is to not burn yourself out by doing too many unnecessary cases.

While each case that you do makes you slightly better, there is a point when doing too many cases can create case fatigue right before your interview. Case fatigue can negatively impact your interview performance.

On the other hand, you also don’t want to go weeks without having done a case. You may end up forgetting strategies or become rusty and slow.

Once you have achieved case mastery, I recommend doing no more than 2 cases per week in the weeks leading up to your interview. This ensures that you remain sharp for case interviews, but don’t have case fatigue.

What resources should I use to prepare for case interviews?

Here are our three resources that we recommend for case interview prep.

These resources teach the best case interview strategies that you only need to learn once. These strategies are robust, effective, and will help you stand out from the hundreds or thousands of other candidates competing for a consulting job offer.

• Comprehensive Case Interview Course (our #1 recommendation): The only resource you need. Whether you have no business background, rusty math skills, or are short on time, this step-by-step course will transform you into a top 1% caser that lands multiple consulting offers.
• Hacking the Case Interview Book   (available on Amazon): Perfect for beginners that are short on time. Transform yourself from a stressed-out case interview newbie to a confident intermediate in under a week. Some readers finish this book in a day and can already tackle tough cases.
• The Ultimate Case Interview Workbook (available on Amazon): Perfect for intermediates struggling with frameworks, case math, or generating business insights. No need to find a case partner – these drills, practice problems, and full-length cases can all be done by yourself.

Case Interview Beginner Mistake #1: Lack of Structure

Failing to establish a clear framework for approaching the problem can lead to a scattered and unorganized response. It's important to outline a structured approach to solving the case.

Case Interview Beginner Mistake #2: Making Assumptions Without Clarification

Assuming information without seeking clarification can lead to incorrect conclusions. It's crucial to ask thoughtful questions to gather all necessary details.

Case Interview Beginner Mistake #3: Ignoring the Importance of Communication

Effective communication is key. Failing to articulate your thought process clearly or not actively engaging with the interviewer can hinder your performance.

Case Interview Beginner Mistake #4: Overlooking the Objective

Some candidates get so engrossed in solving the problem that they lose sight of the ultimate goal - providing actionable recommendations. Make sure your analysis leads to a clear conclusion.

Case Interview Beginner Mistake #5: Rushing Through the Case

Time management is crucial. Rushing through the case without taking the time to think critically about the problem can result in incomplete or inaccurate solutions.

Case Interview Beginner Mistake #6: Neglecting Quantitative Analysis

Many cases involve numerical data. Failing to perform thorough quantitative analysis or making calculation errors can be a significant setback.

Case Interview Beginner Mistake #7: Ignoring Alternative Perspectives

Tunnel vision can be detrimental. Failing to consider alternative viewpoints or approaches to the problem may lead to overlooking valuable insights.

Case Interview Beginner Mistake #8: Focusing Too Much on Memorized Frameworks

While frameworks are useful, relying too heavily on memorized approaches can lead to a superficial understanding of the case. It's important to adapt your framework to the specific context.

Case Interview Beginner Mistake #9: Neglecting to Check Assumptions

Sometimes, candidates make assumptions that are later proven to be incorrect. It's important to periodically revisit and validate your assumptions as you gather more information.

Case Interview Beginner Mistake #10: Lack of Practice and Preparation

Insufficient practice and preparation can lead to nervousness and poor performance during the actual interview. It's important to simulate case interview scenarios to build confidence and proficiency.

Case Interview Beginner Tip #1: Understand the Business Objective

The quickest way to fail a case interview is to answer or address the wrong business problem. Therefore, when the interviewer starts the case by reading the case background information, it is imperative that you identify what is the business problem and what is the primary question you are trying to answer. You should always verify the objective of the case with the interviewer.

Case Interview Beginner Tip #2: Ask Clarifying Questions 

Don’t be afraid to ask clarifying questions. You will not be penalized for this. If there is a term that you are unfamiliar with, ask for the definition. If you don’t understand the objective of the case, ask questions to clarify this. If there is important information that you were not able to write down, ask the interviewer to repeat specific pieces of information.

All of these questions will help strengthen your understanding of the case situation and make it easier for you to solve the case.

Case Interview Beginner Tip #3: Don’t Use Memorized Frameworks

The issue with using memorized frameworks is that they aren’t tailored to the specific case that you are solving for. Many times, some of the elements of your memorized framework will not be relevant or important to the case. Additionally, interviewers can easily tell when you are regurgitating memorized information and not thinking critically.

Instead of memorizing frameworks, memorize a list of 8 – 10 broad business areas, such as the following:

• Competition
• Profitability
• Alternatives

When given a case, mentally run through this list and pick the 3 to 4 areas that are the most relevant to the case. If the list does not give you enough framework areas, brainstorm and add your own areas to your framework.

Case Interview Beginner Tip #4: Structure Your Math Approach 

Before doing any math calculations, lay out an upfront approach or structure to walk the interviewer through what you are about to do. Developing a structure will help you avoid making unnecessary calculations or reaching a dead-end. If the interviewer approves of your approach, then the rest of the math problem is simple arithmetic.

Case Interview Beginner Tip #5: Use Abbreviations for Large Numbers

If you are working with large numbers in the thousands, millions, billions, or trillions, use abbreviations rather than writing out all of the zeroes.

For example, 10,000 can be expressed as 10K, 200,000,000 can be expressed as 200M, and 300,000,000,000 can be expressed as 300B. This reduces the chances that you’ll accidentally add or drop a zero in your numbers.

Case Interview Beginner Tip #6: Talk Through Calculations Out Loud

Talking through your calculations out loud provides two benefits. One, it decreases the likelihood that you’ll make a mistake. Two, it makes it easier for the interviewer to follow what you are doing. If you happen to get stuck or make a mistake, the interviewer can jump in to offer suggestions or guidance. The interviewer cannot do this if you are not communicating exactly what you are doing.

Case Interview Beginner Tip #7: Sense Check Your Numbers

Accidentally missing zeroes or adding extra zeroes during your case interview calculations is the most common math mistake. To avoid this, you can do a quick sense check after each calculation to confirm that your answer is the right order of magnitude.

For example, if you are multiplying 115 million by 22, you should expect your answer to be in the billions because 100 million * 20 = 2 billion.

Case Interview Beginner Tip #8: Talk Through The Axes of Charts and Graphs

When given charts or graphs to interpret, the very first thing you should do is to look at the axes. This is the most effective way to understand what the chart or graph is showing. When you are given multiple charts or graphs, this will also help you understand how each chart or graph relates to each other.

Case Interview Beginner Tip #9: Answer “So What?” After Every Question

When the interviewer asks you a quantitative or qualitative question during a case interview, don’t just answer it and stop there. After answering the question, ask yourself: “so what?” How does your answer help you solve the overall business problem? What implications does your answer have for your potential recommendation? You should be tying each answer that you give back to the case objective.  

Case Interview Beginner Tip #10: Have a Firm Recommendation

You do not want to have a flimsy recommendation in which you switch back and forth between two different recommendations. Instead, have a recommendation that takes a firm stance. Remember that there is no right or wrong recommendation. As long as your recommendation is supported with data and evidence, your recommendation will be accepted.

9 Tips For Delivering A Stellar Case Presentation Interview

A Case study interview is a staple in the recruitment process for firms in the professional services industry, particularly management consulting firms. But recently, many companies use what is called a “case presentation interview” to test more than just the candidate’s ability to crack a case. 

In the past, case presentation interviews (usually the second or third in the interview series) were commonly used in the hiring process of associate-level employees, mostly for working directly with business clients and offering billable services.  

Recently, case presentation interviews are used for analyst-level employees in many healthcare, tech, and e-commerce consulting firms. 

In this article, you will learn what skills a case presentation interviewer is looking for, the biggest challenge of a case presentation interview, the major tips you can use to ace your case presentation interview and land your dream job! + a bonus Insightful video with tons of examples for consulting case interviews.

What is a case presentation interview?

Case Presentation Interviews usually follow this process:

What skills are the interviewer looking for during a case presentation interview?

The ultimate goal of the interview is not necessarily to see if the person being interviewed can solve the business problem (although, very important), but to see if they can think on their feet, reason like a consultant, communicate their insights effectively before clients and/or the CEOs. 

A case presentation interview is an interviewee’s opportunity to prove to their interviewer that their soft skills and analytical skills are relevant within a realistic business context. 

In many firms, the case presentation interview is often carried out as a group assessment exercise. When this happens, the candidates are handed briefing materials about a business issue, then asked to collaborate, discuss and proffer a solution to the issue. While this goes on, the interviewer(s) sit silently and watch as silent observers.

What is the biggest difficulty in case presentation interviews?

Time management tops the list of difficulties that would be faced during a case presentation interview. The firm often provides the interview candidate with a large set of data and extrinsic information. 

It would be a complete waste of time if the candidate tries to read through the details. It is much wiser for the candidate to form an opinion first and fast, and then find the data that is needed to support their thought.

9 Tips on how to deliver an excellent Case Presentation Interview

You have to prepare extensively for your case presentation interview, and one of the ways you can do this is by brushing up on your mental maths skills. 

You can do this by randomly giving yourself a short but budgeted time to solve semi-difficult maths problems without using a calculator.

You can use information from case books as practice just so that can get ahead of the curve. It would also be wise for you to extract just the prompt and data as many case books already come with answer keys. 

There are three things you can do to help yourself:

The amount of knowledge you have acquired about the company will help you discover their style and know their archetypes. You would be able to solve the business issue in a way that they normally would recommend. 

You can use these four easy steps to create structure:

Regardless of the choice of framework or data, ensure all your steps are logical and that your thought process flows unhindered. 

Most traditional case interviews pose as difficult because the relevant data has to be mined; this is not the case for case presentation interviews, the limited information supplied to the interviewee contains everything they need. Once you form your hypothesis, you can cut right to the chase and start testing instantly to see what direction you should head towards. 

As mentioned above, the interviewers are not solely looking to see if you proffered a solution to the business problem, they’re also assessing and judging your confidence, they want to see how you would perform in a real consulting scenario. Practice public speaking often to prepare for the presentation stage of the case presentation interview. 

Just so you know, whether the allotted time is 30 minutes or 2 hours, it would go by very quickly, hence the need for a time budget. Interviewers often understand the limited time constraints, but you must move on from spending your time analyzing the information and draw out their presentation quickly.

Transparency is an impressive quality to many firms, and they would be impressed by your honesty.

With this, chances are very high that both you and the firm reach a mutual realization and an agreement if the firm and the role are great for you.

What Is a Case Interview and How Do You Ace It? (+Examples)

6 min read · Updated on June 16, 2022

With case interviews being used more frequently for general consulting roles, it is essential to know how they work.

Unless you've interviewed for a management consultant or investment banking job, chances are you haven't experienced a case interview. However, this rather unique interview process is slowly becoming the norm for a wider variety of management consulting roles.

That's why you should know what to expect and how to handle it professionally.

What is a case interview?

A case interview is defined as “a hypothetical business situation that is presented during the job interview process to determine how a candidate thinks about a particular problem and how they would solve it.”

Usually, this specific business problem or situation is one that a candidate would face if hired for the job in that specific company. For example, a candidate's prompt might be determining whether there's a market for home-use ultraviolet sterilizers. They could begin by asking about the target market, the cost of each unit, and how they'll be sold. As they get into it, they may offer ideas on how to create more markets, like making the units in different sizes or for specific items like phones.

The overall goal is to assess how the candidate as a consultant thinks about and arrives at particular solutions or answers for a specific business problem scenario. 

How is a case interview structure different from other interview formats?

As with a regular or competency-based interview format, the traditional case interview seeks to assess a candidate's skills coupled with how they operate in a specific hypothetical business situation. However, that is where most of the similarities end.

Rather than talking about how you handled something in a past or present job, a case interview presents a particular situation and asks you to work with it right there in the job interview.

Answers for case interview questions can be verbal or written and often include the creation of charts, graphs, or illustrations to make your point. What's more, case interview questions may also feature brain teasers or other analytical tasks that are not related to the company or the job. Also, unlike a regular interview, it's acceptable and expected that the candidate interacts with and asks questions of the interviewer as part of the problem-solving process.

But, perhaps the biggest difference is that there's no one “right” or correct answer to the questions or scenarios because there is often more than one acceptable way to handle the hypothetical situation. In fact, interviewers are looking for ingenuity and that “out-of-the-box” thinking strategy.

To sum up, it's just as much about the process as the solution.

Which businesses benefit from case interviews?

In general, case interviews work best for consulting firms, but most companies can benefit from determining whether or not a candidate can effectively size up and handle real-life business situations. Not only does it demonstrate a person's problem-solving skills and analytical abilities, but it also shows their willingness to get more information by asking questions.

Essentially, interviewers are watching as candidates figure out what they're looking for, what analysis they want to use, and what insights and theories they develop as they move toward a data-driven, quantifiable solution. These interviewers are also looking for strong interpersonal abilities and communication skills — management consultants must deal with people as well as data after all.

Are there specific case interview formats?

There are a few basic formats used in case interviews.

Candidate-led scenarios

In candidate led case interviews, the candidate is required to lead the discussion and development of the case. You'll be evaluated on developing and evaluating your theory while simultaneously formulating and answering the relevant questions needed.

You don't have to work from beginning to end but are able to move among and focus on different aspects of the case as you solve it.

Interviewer-led scenarios

In interviewer-led case interviews, these interviews have a preset format where the interviewer directs the focus, tempo, and sequence of the problem-solving process, with candidates solving the case from beginning to end. Each problem has predetermined questions, and you may or may not be given data to work with.

The approach and evaluation parameters are the same as the candidate-led interview.

Group scenarios

In a group case interview, here you work with a team of other candidates to analyze the case, collaborating to come up with solutions.

Presentation-only scenario

You have two hours by yourself to review data, create a premise, build an issue tree, and analyze your results. You then present this to the interviewer, who will question and challenge your data just like a client would to see how you defend your results.

Case interview sample questions

There really are no “typical” case interview questions; rather, you're presented with a situation or business problem and asked to handle it.

Here's a case interview question example.

“Our client is a five-million-dollar manufacturer of eye-glass frames whose sales have dropped markedly in the past 3 years. What should they do?”

If your interviewer utters the words “Our client…”, you know you're in a case interview.

How to prepare for a case interview

Case interview prep is the key to success. Luckily, there are only a few case interview “types” that are regularly used, and your job is to know and study them. They are:

New product development

Pricing strategies

Entering a new market space

Growth strategies

Starting a new business

Improving profitability/increasing sales/reducing costs

Acquiring a company

Create your own situations around these case interview examples, practicing your answers alone or with a buddy. You can also look up actual examples of these cases, review the analysis, and come up with your own unique solutions.

Preparation and practice will make the actual case interview much less daunting and allow you to feel more confident. The more you can actually relax and have fun in a case interview, the more likely you are to enjoy the actual work — and get hired to do it.

State prepares to give argument in correspondence school case

ANCHORAGE, Alaska (KTUU) -The State of Alaska is preparing to present its argument to the Alaska Supreme Court to reverse an April ruling by the Alaska Superior Court that found the correspondence study program unconstitutional.

Two lawmakers who are also homeschool parents responded Wednesday about the state’s upcoming case; both had different perspectives.

Anchorage Rep. Alyse Galvin has four children who have gone through correspondence programs, and she agrees with Superior Court Judge Adolf Zeman that public reimbursement for correspondence students’ individual learning plans can not be used for education expenses at religious or private institutions.

“There have been some families who have been taking their allotment, their money, their checks, and putting that into private school tuition,” Galvin said.

However, Homer Rep. Sarah Vance says she has a couple of issues with the judge’s ruling, which she calls “sweeping”.

Vance is the mother of four homeschooled children through the Connections Homeschool program in the Kenai Peninsula Borough School District. She agrees with the state that the Superior Court ruling fails to properly apply the standard for holding that a statute is facially unconstitutional.

”For decades, State money has been spent on correspondence schools using private vendors to ensure students who don’t (or can’t) attend a traditional neighborhood school still have access to a top-quality public education. The lower court’s decision upended that decades-long precedent, ignoring the vast majority of constitutional spending on educational materials and services purchased by parents to support their child’s public education.,” said Alaska Deputy Attorney General Cori Mills.

Saying the judge’s decision is an overreach and supporting the state’s argument that the judge is putting a broad definition around the word private. Vance said the judge’s and Planitff’s attempt to prevent public funds from being used for tuition at private schools could have untended consequences.

“Does this mean that we can’t pay for the art class, here at the local gallery by leading artist? Does this mean that the educational books that are from a private institution can no longer be paid for,” Vance said.

Galvin says she doesn’t believe the judge’s ruling is that broad and specifically pertains to the use of public money at private institutions.

“We know what we should be doing. I think we got on a track that was benefiting a few families in a way that wasn’t fair. And someone called it out. And now we’re gonna get our act together and do it right and do it better,” Galvin said.

However, Vance feels the state is in a strong position to make its case before the Alaska Supreme Court.

“I feel that we should not discriminate on that, education that should be left to the parents and have the parent‘s choice and the quality of education that they provide. And it seemed like this judge was making a political decision rather than a lawful one, " Vance said.

The state and the plaintiffs in the case are due to make their cases in front of the Alaska Supreme Court in Anchorage at 10 a.m. on June 27.

Sky political editor Beth Rigby  has been speaking to Housing Secretary Michael Gove.

Just before their interview began, the BBC reported that Tony Lee, the director of campaigns for the Conservative Party, was also facing a Gambling Commission investigation.

In response, Mr Gove said he was "almost lost for words".

While we have to wait for the investigations to conclude, he added, "You shouldn't be using inside information to try to make a few hundred quid on the side".

"That is just not acceptable."

It's "terrible", he said - adding that he was "disappointed" as the "future of this election really matters to me and my children".

It's been a blistering few hours in political news after more allegations of betting by a Conservative candidate surfaced.

So here is a quick summary of what we know.

Craig Williams, a close parliamentary aide of Rishi Sunak, admitted to placing a "flutter" on the date of the election "weeks ago".

This is reported to have happened just before the prime minister surprised many by calling a vote for 4 July, with Mr Williams said to have staked a £100.

The Conservative Party said it was a personal matter.

Mr Williams is the party's candidate for Montgomeryshire and Glyndwr.

It emerged that one of Mr Sunak's close protection police officers had been arrested over alleged bets on the timing of the election.

Sky News understands several bets were placed, with at least one of them being a three-figure sum.

Read more on this story here:

It emerged overnight that Laura Saunders, the Tory candidate for Bristol North West, is facing an investigation by the Gambling Commission.

Ms Saunders is married to Tony Lee, who is the party's director of campaigns.

The Gambling Commission has not commented on individual cases.

But it said today that "currently the commission is investigating the possibility of offences concerning the date of the election".

It added: "This is an ongoing investigation, and the commission cannot provide any further details at this time."

The Conservative Party said they had been contacted by the commission about a "small number" of individuals.

As expected, the Bank of England has held interest rates at 5.25% for the seventh time in a row.

The Monetary Policy Committee's vote in favour of maintaining the 16-year high in rates had been widely expected by economists and financial markets.

You can follow dedicated updates in our Money blog here:

In the past few minutes, the Conservative Party X account has deleted an advert uploaded yesterday.

The video, which features scenes from a roulette wheel, bears the slogan: "If you bet on Labour, you can never win."

It was posted before the revelations about one of Rishi Sunak's protection officers being arrested over alleged political bets.

It also predated claims about Laura Saunders and her husband Tony Lee.

Housing Secretary Michael Gove has been speaking to broadcasters this morning, after more allegations surfaced that Tory candidates bet on the date of the election.

Mr Gove says what has been claimed is "very, very, far from satisfactory behaviour".

He acknowledges that the world will think the look of what's transpired "is not great".

But the allegations are being "investigated" now - and the party will be doing "much more than just raising an eyebrow".

Asked if he had seen a similar situation before, Mr Gove says that in campaigns there can be "human lapses by individuals".

He adds: "My view is let the process take its course, be properly critical of people who've made mistakes, and then in the fullness of time, hope that they can find forgiveness."

Starmer calls for suspensions

At the same time as Mr Gove was speaking, Labour leader Sir Keir Starmer was also talking to journalists.

He called for the suspension of candidates who were being investigated.

Sir Keir said: "This candidate should be suspended and it's very telling that Rishi Sunak has not already done that. 

"If it was one of my candidates, they'd be gone and their feet would have not touched the floor."

By Rob Powell , political correspondent

Politics, as with comedy, is so often about timing.

And you'd have thought the Conservative official in charge of social media may have sensed danger before putting out an advert on party channels featuring a roulette wheel and the accompanying caption: "If you bet on Labour, you can never win."

That's because within hours of the button being pushed on that post, it was confirmed that a second Tory candidate was being investigated for allegedly placing a bet on the timing of the general election shortly before it was publicly announced.

Now, we also know that Laura Saunders - who is standing in Bristol North West - is married to the party's director of campaigning, someone who you'd assume would have access to private information potentially about the election.

This matters legally because it is an offence to use inside information not available to others to gain an unfair advantage when placing a bet.

But it also matters politically for two reasons.

Read Rob's full analysis here:

Pat McFadden, Labour's national campaign coordinator, has written to Rishi Sunak about the betting "scandal" currently unfolding in the Conservative Party.

It comes after one of the prime minister's aides - who is also an election candidate - admitted betting on the date of the election, a member of his protection detail was arrested over allegations of similar bets, and another Conservative candidate faces an investigation over similar claims.

Mr McFadden said: "Dear prime minister, I am writing to you regarding the scandal that is unfolding around your announcement of the general election on 22 May, and the growing number of individuals accused of making bets to try to profit from their inside knowledge of that announcement."

He added: "Can I ask you very simply why you think that a serving police officer should be suspended from his role, because of allegations that he made a bet based on inside information, while the two colleagues of yours who so far stand accused of the same offence - Craig Williams, your PPS, and Laura Saunders, a member of your CCHQ staff and partner of your campaigns director - are still being allowed to stand as Tory candidates in the election on 4 July?

"Surely you can understand that - yet again - this looks as though there is one rule for members of the Tory party, and another rule for everyone else, specifically on this occasion a serving police officer. 

"If you can see how wrong that is, will you now at the very least remove your support for Mr Williams and Ms Saunders as Conservative election candidates?"

The Labour frontbencher adds: "I urge you to gain a sense of urgency and decency about this matter, and do what is necessary both to establish how wide this scandal goes, and take immediate action against all those implicated. 

"It will speak volumes if you choose to stay silent and do nothing instead."

Tony Lee, the Conservative Party's head of campaigns, took a leave of absence last night, Sky News has been told.

This was around the same time the story first broke that his Conservative candidate wife - Laura Saunders - was facing being investigated by the Gambling Commission.

Mr Lee appears to have made his social media accounts private, but was announced as the party's campaign chief role back in 2022 at the Conservative Party conference.

He has also worked for Andy Street, who until recently was the Conservative mayor of the West Midlands.

Mr Lee described himself as "an experienced political campaigner with over 20 years experience in running election".

His past includes "successfully leading Andy Street's re-election campaign as mayor of the West Midlands in 2021 and numerous local election campaigns".

Sky deputy political editor Sam Coates has been analysing the developments around the potential investigations into bets placed on the date of the general election by Conservatives.

He says it is a "big, big, big problem" for the government.

"This is one of those stories that everybody can understand," Sam adds.

"First, it was his top parliamentary aide - called Craig Williams - who has admitted and apologised for putting a bet on the date of the election, three days before Rishi Sunak called that election.

"He's being investigated by the Gambling Commission. 

"Now a second candidate who just so happens to be married to somebody in Conservative headquarters who deals with campaigning, they are also under investigation.

"And, a member of the prime minister's police protection squad, they were arrested earlier in the week. 

"And it does look as if people immediately around the prime minister may have been looking to eke out some personal advantage, by having this bit of super secret information that the rest of us weren't privy to about the election date.

"An election date which I have to say is a gamble that, for everybody else in the Conservative Party, looks like it's gone wrong. 

"But for those three people, it looked like they tried to get an upside, but they look like they might have been found out."

Our live poll tracker collates the results of opinion surveys carried out by all the main polling organisations - and allows you to see how the political parties are performing in the run-up to the general election.

It currently shows a drop in support in recent days for Labour and the Tories - with a jump for Reform and the Liberal Democrats.

EXCLUSIVE – Toward a New Global Approach to Safeguard Planet Earth: An Interview With Johan Rockström

In an exclusive interview with Earth.Org, Professor Johan Rockström, the lead scientist behind the planetary boundaries framework, discusses how recent climate trends are worrying the scientific community and the importance of adopting a new global governance approach that protects and preserves the regulating functions of the Earth system, critical for life on our planet.

For more than a century, scientists have monitored climate trends and provided governments, businesses, and stakeholders with the understanding necessary to shape modern human lifestyles in a way that benefits both economic development and human well-being.

During the 1970s, scientific understanding of Earth systems increased tremendously and in the decade that followed, evidence of climate change began spreading. Since the establishment of the Intergovernmental Panel on Climate Change (IPCC) in 1988, the scientific community began looking at the planet with different eyes – as a complex, self-regulating bio-geophysical system characterized by interconnected spheres – lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).

At the same time, scientists began developing an understanding of tipping points , multiple stable states of an Earth system that, if pushed too far, could result in unstoppable, permanent, and irreversible changes in the state of that system. For instance, continuous external pressure on a system like the Amazon rainforest , the world’s largest and richest biological reservoir and one of the most important natural carbon storage systems , can turn the forest into a savannah and a source of carbon dioxide.

More on the topic: The Tipping Points of Climate Change: How Will Our World Change?

A turning point in climate science came in 2001, when the IPCC featured in its Third Assessment Report the popular “hockey stick” graph, an illustration of the changes in global temperatures of the past millennium that revealed an unprecedented, sharp upward trajectory towards the end of the 1990s and into the new century – the “blade” of the hockey stick. While the graph does not specifically attribute this increase to fossil fuel emissions, it aligns with the broader scientific consensus that human activities, including the burning of fossil fuels, have been a primary driver of the observed global warming trend.

All the evidence gathered in the course of four decades left scientists with two key questions: What are the biophysical processes that regulate the state and health of the planet? Once identified, could we quantify safe boundaries that give us a good chance to keep the planet in a liveable state – but beyond which we risk causing a drift away from that state?

“Answering these questions was the next inevitable step in climate research at that point,” said Professor Johan Rockström, who sat down to speak with Earth.Org while on a visit to Hong Kong to attend the One Earth Summit in March 2024. 

Rockström is the director of Germany’s Potsdam Institute for Climate Impact Research and lead author of the planetary boundaries framework, an important body of climate research that has generated enormous interest within the fields of sustainability and environmental policy. The framework has served, and continues to serve, as a valuable guide for policymakers, urging them to consider the long-term consequences of human actions and adopt strategies that prioritize the sustainable use of Earth’s resources.

‘Danger Zone’: The Consequences of Transgressing Planetary Boundaries

First published in 2009, the planetary boundaries framework defines and quantifies the limits within which human activities can safely operate without causing irreversible environmental changes. It does so by identifying several critical Earth system processes and defining thresholds – or boundaries – that should not be exceeded to maintain a stable and sustainable planet.

The framework consists of nine interrelated planetary boundaries: climate change, biodiversity loss, land use change, freshwater use, ocean acidification, ozone depletion, atmospheric aerosol loading, chemical pollution, and the introduction of novel entities. Each boundary represents a specific aspect of the complex biophysical Earth system that is essential for maintaining a stable and habitable planet.

“Boundaries are set to avoid tipping points, to have a high chance to keep the planet in state as close as possible to the Holocene, that allows it to maintain its resilience, stability, and life support capabilities. Go beyond and we enter a danger zone… the uncertainty range of science,” Rockström explained. In 2023, he and other scientists at the Stockholm Resilience Center in Sweden published an update of the framework. The study found that six of the nine planetary boundaries are already transgressed , placing the Earth “well outside of the safe operating space for humanity.”

“Unfortunately for climate, six of the nine planetary boundaries are operating outside the green space… with a high risk of triggering irreversible changes,” Rockström said.

To better understand the “danger zone” scenario, it is worth looking at an example.  

Both ocean- and land-based ecosystems are dominated by what scientists call “negative feedbacks,” any processes or changes that act as buffering systems, regulating the planet’s functions and keeping it in a healthy state by limiting or reducing the impacts and severity of an initial change.

“Feedback processes are what we measure with planetary boundaries. Keep them in the green to remain at the right side of the fence, go into the danger zone and they start wobbling.” 

Concretely, these processes are found, among others, in forests and oceans, both of which have the extraordinary capacity to absorb and store about 25% of the carbon dioxide (CO2) present in the atmosphere, respectively. Oceans also capture about 90% of the excess heat generated by these emissions.

“These absorption rates combined are the biggest subsidy to the world’s economy. It means that half of our climate debt is hidden under the carpet of a forgiving planet,” Rockström explained. “We enter a danger zone, and these systems start to misbehave.” 

This is the case for some parts of the Amazon biome – the world’s single-largest carbon stock – which, according to a 2021 study , is now releasing more carbon than it is absorbing. “It is no longer helping us, it’s becoming a negative force,” he said. 

Similarly, the Greenland ice sheet, capable of reflecting around 89% of incoming heat from the sun back to space, has experienced unprecedented melting for decades due to the relentless rise in global temperatures, and it is now melting at double the rate at the beginning of the century . This affects the reflectivity power of the ice sheet: as melted water becomes darker, it begins absorbing heat instead of reflecting it, a process known as ice-albedo feedback. 

“The moment a system absorbs more than it releases, it has crossed a tipping point and you cannot stop it. It goes from a cooling to a self-warming system,” explained Rockström.

So far, human activities – primarily the burning of fossil fuels – have increased global average temperature by 1.48C; this, however, represents a mere 2% of our heat contribution. The remaining excess heat is absorbed by and stored in the world’s oceans (89%), stored in land masses (5-6%), and about 4% is available for the energy-intensive melting process of ice and glaciers. 

“It’s a huge paradox,” said Rockström. “One of the biggest threats to humanity [melting ice] hides more warming than the fossil fuel emissions we’ve caused so far. Imagine what would happen if ice disappeared.”

“This alone is enough to explain the significance of the planetary boundaries.”

‘Shocking’ Trends

Early understanding of the anthropogenic impacts of human activities on the planet did not lead to the fundamental changes our society needed at the time to prevent the situation from worsening further. Thanks to our inaction in recent decades, we now find ourselves in completely uncharted territory. 

“Humanity has opened the gates to hell,” United Nations Secretary-General António Guterres told the UN General Assembly in 2023, warning that “humanity’s fate is hanging in the balance.”

The past nine years have been the hottest on record , with 2023 topping the ranking . Last year’s record-breaking temperatures can be partly attributed to the return of El Niño , a weather pattern associated with the unusual warming of surface waters in the eastern equatorial Pacific Ocean. However, despite scientists confirming the gradual weakening of the pattern in recent weeks, the trend has continued well into the new year, with this past winter as a whole setting new high-temperature marks and March 2024 marking the 10th consecutive hottest month on record , both in terms of air and sea surface temperature. 

What’s even more worrisome is that climate scientists are struggling to understand or explain these trends, which climate scientist Zeke Hausfather last year famously described as “absolutely gobsmackingly bananas.” 

“We had seen El Niño conditions before, so we expected higher surface temperatures [last year] because the Pacific ocean releases heat. But what happened in 2023 was nothing close to 2016, the second-warmest year on record. It was beyond anything we expected and no climate models can reproduce what happened. And then 2024 starts, and it gets even warmer,” said Rockström. “We cannot explain these [trends] yet and it makes scientists that work on Earth resilience like myself very nervous.”

Recent data also show a relentless rise in global sea temperatures, which have doubled since the 1960s .

“There has always been the assumption that the ocean can cope with this, that the ocean is able to absorb this heat in a predictable, linear way, without causing surprise or any sudden abrupt changes. Up until 2023. Because suddenly, temperatures [went] off the charts, and that’s what is so shocking,” said the Swedish scientist.

Ocean warming has potentially huge implications for marine ecosystems such as coral reefs and coastal communities. What we are witnessing in our oceans, Rockström explained, has never been observed before and could be “a sign of collapse.”

“Has the ocean tipped over? We simply do not know. We don’t know if we are causing permanent changes. One thing we do know, unfortunately, irrespective of whether it’s a permanent change or not, is that it is virtually certain that this will knock over all the tropical coral reefs systems.”

Coral reefs are extremely important ecosystems that exist in more than 100 countries and territories and support at least 25% of marine species; they are integral to sustaining Earth’s vast and interconnected web of marine biodiversity and provide ecosystem services valued up to $9.9 trillion annually. They are sometimes referred to as “rainforests of the sea” for their ability to act as carbon sinks by absorbing the excess carbon dioxide in the water. 

Unfortunately, reefs are disappearing at an alarming pace . According to the most recent report by the Global Coral Reef Monitoring Network (GCRMN), the world has lost approximately 14% of corals since 2009 . 

In April 2024, scientists confirmed that the world is undergoing its fourth global coral bleaching event and already the second in the past ten years. “As the world’s oceans continue to warm, coral bleaching is becoming more frequent and severe,” said  Derek Manzello, coordinator of the US National Oceanic and Atmospheric Administration’s Coral Reef Watch (NOAA CRW). “When these events are sufficiently severe or prolonged, they can cause coral mortality, which can negatively impact the goods and services coral reefs provide and that people depend on for their livelihoods.”

Toward a New Global Approach to Safeguard Planet Earth

The planetary boundary framework was designed not only to define the environmental limits within which humanity can safely operate but also to guide global sustainability policy development and inspire meaningful action on a national and international level to ensure that these boundaries are not transgressed.

At the core of this is a newly established paradigm that Rockström and other scientists worked on for years and presented to the world in a paper published in January 2024. 

In light of recent climate trends, the team revisited the long-standing “global commons” concept, a framework that regulates the governance of four planetary systems: the atmosphere, the high oceans, outer space, and Antarctica. These systems are non-rival, meaning they are not owned by anyone and do not fall into a national jurisdiction, and non-excludable, meaning no one can prevent anyone from accessing them.

But as Rockström put it, the global commons system “is no longer enough” and it is time the international community adopts a more effective and comprehensive approach that safeguards critical regulating functions of the Earth system.

For this reason, the new approach suggests complementing the existing framework, which only takes globally shared geographic regions into account, with an additional legal entity: the planetary commons. The new paradigm incorporates all “critical biophysical systems that regulate the resilience and state, and therefore livability, on Earth” and that we collectively depend on for life support, irrespective of where we live or where they are located. These systems include tipping elements such as the Amazon rainforest, the Greenland ice sheet, and the Atlantic Meridional Overturning Circulation ( AMOC ).

“It is quite a revolutionary paradigm, but entirely consistent with planetary boundaries science. It changes the game entirely.”

The main argument in favor of the new approach is establishing a regulatory framework to govern planetary commons on an international scale, given that their benefits and contributions are far-reaching and extend well beyond national borders. 

A great example of this is the Amazon rainforest, which spans across nine nations and 3,344 formally acknowledged indigenous territories. While being an important national asset, the rainforest also supports a myriad of ecosystem services, acting as a huge repository for Amazon countries and humankind. 

This sentiment was echoed in Brazil’s Minister of Environment and Climate Change Marina Silva’s speech at last year’s UN climate summit in Egypt: “Protecting forests means protecting the balance of the planet and the oceans… Commitment to the forest is not just from the government. It’s about business, society and science.  And we work with all these pillars – because protecting the forest is not just a government action, it is an action by all of humanity.”

“[President] Lula and Marina da Silva understood this very clearly before our paper was even published. Planetary commons have to be governed and protected by the international community. I’m as keen to keep the Amazon rainforest intact as an indigenous Brazilian community,” said Rockström.

Future Outlook

Despite all the science available, climate progress on a global level has been remarkably slow, putting the world off track on its climate targets. All three main greenhouse gases reached historic highs in 2023 and according to the most recent data, the world has now just around six years left before it runs out of the carbon budget required for a 50-50 chance to keep the global temperature rise below 1.5C. 

“The reason why [scientists] are using stronger and stronger language… is that we’re running out of time, not that the evidence is changing so much,” Rockström argued. He said no credible study shows us that we can achieve the 9% yearly emissions reduction needed between now and 2030 and the only chance we have at achieving that is by “doing everything right on nature, phase out fossil fuels, and get serious on carbon dioxide removal.” 

But by far the most effective way to do this, he argued, is carbon pricing , a policy approach aimed at reducing greenhouse gas emissions by putting a price on CO2 and other greenhouse gas emissions. So far, the European Union’s price is among the highest in the world and the nearest one to the social cost of carbon (SCC), an estimate of the economic damages that would result from emitting one additional ton of carbon dioxide into the atmosphere, which a 2022 study put at around US$185 per tonne of CO2.

“Every economist hates subsidies and [carbon pricing] is the biggest subsidy in the world. But that would be the fastest way [to reduce emissions]. Put a $200 price tag on carbon dioxide, give all that money to a Loss and Damage fund, and off we go.”

How Retailers Became Ad Platforms

• Sebastian Gabel,
• Duncan Simester,
• Artem Timoshenko

It’s a major growth opportunity — if companies can navigate the strategic challenges.

Major retailers are today, most notably Amazon, are creating and operating their own advertising platforms — and they’re making millions doing it. McKinsey estimates that by 2026, retail media will add $1.3 trillion to enterprise values in the U.S. alone, with profit margins between 50% and 70%. In this article, the authors introduce readers to the main kinds of retail media, discuss three strategic challenges that they present, and provide guidance for effectively managing those challenges.

A rapidly growing number of major retailers are today creating and operating their own advertising platforms — a phenomenon widely referred to as retail media.  Nobody has had more success in the space than Amazon, which in 2023 earned $46.9 billion from advertising, comprised primarily of sponsored ads on its site. This figure exceeds the annual global revenue of Coca-Cola and makes Amazon the third-largest advertising platform in the United States, behind only Google and Facebook.
