What is a Consulting Group Case Interview?

Consulting group case interviews are a special variant of the traditional case interview. Before preparing for group case interviews, you should first become familiar with how to solve a traditional case interview .

Like a case interview, you’ll still be placed in a hypothetical business situation and asked to develop a recommendation or answer to a business problem. However, for consulting group case interviews, you’ll be put in a group of 3 to 6 people with other candidates that are also interviewing for the same consulting job.

The group will be given materials which contain the case background, objective, and other information needed to solve the case. You’ll initially have some time to read the information independently, but will spend most of the time discussing the case and working together as a group.

During these discussions, the interviewer will be observing and taking notes on each candidate.

For some group case interviews, you will also create a group presentation. As a group, you’ll present your recommendation to the interviewer who will ask follow-up questions on the work and findings.

Consulting group case interviews are much less commonly used than traditional case interviews, but they are as equally as important. They are typically given in second or final round interviews .

For firms and offices that use group case interviews, you will not receive a consulting job offer unless you can pass them.

Different Formats of Consulting Group Case Interviews

There are two different formats of consulting group case interviews:  

Discussion only group case interviews

Presentation group case interviews.

A discussion only group case interview has the following structure:

This format of group case interview has no presentation component. The group will be given materials with the case background information and objective.

You’ll have some time to read the information independently, but then the interviewer will bring the group together and ask the group to discuss different questions related to solving the case.

The interviewer will be heavily involved in the discussion by asking questions for the group to answer and steering the direction of the discussion.

The discussion only group case interview is focused on assessing the answers that candidates contribute to the group and how well candidates communicate with each other.

A presentation group case interview has the following structure:

The group will be given materials that not only contain the case background and objective, but contain other information needed to solve the case. There is typically more material given in this format because you will be given more time to prepare and discuss.

The group will be given about an hour to discuss the case and create a group presentation. During this time, the interviewer will be listening in on the conversations that the group will have, but they will not interfere or answer any questions.

It is up to the group how they want to allocate their time, what topics they want to discuss, and how they want to handle creating and giving the group presentation.

Once time is up, the group will present their work and findings to the interviewer, who will ask follow-up questions.

The presentation group case interview is focused on assessing how well each candidate contributes to the group, how well candidates work with each other, and the quality of the final presentation.

Why are Consulting Group Case Interviews Used?

Consulting group case interviews are used because they are another way for consulting firms to predict which candidates would make the best consultants.

Group case interviews simulate the consulting job by placing you in a hypothetical business situation. You will need to work as a team to analyze and discuss information and then give a presentation on your recommendation. This is what consultants do every day .

These types of case interviews are used in addition to traditional case interviews because they assess a set of skills that traditional case interviews cannot assess.

Group case interviews focus on teamwork and collaboration. By putting candidates into groups, interviewers can assess how candidates work with other people and how open candidates are to other people’s ideas.

They can see how effectively candidates communicate and persuade teammates and how candidates can balance listening and leading.

What do Consulting Group Case Interviews Assess?

There are four major qualities that group case interviews assess.

Logical, structured thinking : Consultants need to be organized and methodical to work efficiently.

• Can you structure complex problems in a clear, simple way?
• Can you use logic and reason to make appropriate conclusions?

Interpersonal skills : Relationships are important in consulting. You’ll be working with teammates and clients every day, so fostering strong relationships is imperative.

• Are you easy to work with?
• Can you handle conflict or disagreement with teammates?

Teamwork skills : Consultants work closely in small teams. To be successful, consultants need to know how to work effectively in groups.

• Can you make meaningful contributions while working in a group?
• Do you bring out the best ideas and qualities in other people?

Presentation skills : Consultants need strong communication skills to present their work in a clear, concise, and persuasive way.

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

How to Solve Consulting Group Case Interviews

Solving consulting group case interviews follows the same steps as solving traditional case interviews. There are four main steps:

• Understand the problem
• Create a framework
• Answer quantitative and qualitative questions
• Develop a recommendation

1. Understand the problem

The first step to solving a consulting group case interview is to fully understand the problem or objective. What is the overall business question that the group is trying to answer?

Answering or solving the wrong business problem is the quickest way to fail a group case interview.

2. Create a framework

Next, as a group, you’ll want to create some kind of framework to help you solve the case. A framework is a tool that helps you structure and break down complex problems into simpler, smaller components.

For group case interviews, your framework will help guide the group discussion. The framework collects and organizes all of the topics that the group needs to discuss and all of the questions the group needs to answer.

3. Discuss and answer quantitative and qualitative questions

Once your group has aligned on a framework to use, you can move onto the discussion. During the discussion, you will answer many of the questions that were raised in the framework that was created.

Some of these questions will be qualitative, requiring only business knowledge and judgment to answer. Other questions may be more quantitative, requiring some calculations or estimations from the case information provided.

It is up to the group what order they want to answer and discuss the questions. It is also up to the group whether they want to tackle these questions as an entire group or if they want to split up into smaller groups.

Discussion will continue until the group has reached an answer or conclusion that is accepted by everyone.

4. Develop a recommendation

Once you have finished discussing and answering all of the important questions, you will need to align on an overall recommendation.

To do this, review all of the answers and conclusions that the group has drawn. Identify which recommendation they collectively support.

If the group case interview has a presentation component, you will also need to decide how to split up the presentation across the different members of the group.

How to Stand Out in Consulting Group Case Interviews

The best way to stand out and distinguish yourself in a group case interview is to focus on adding as much value as you can to the group.

There are six different ways you can add value to the group.

Lead or facilitate the discussion

If the interviewer is not leading the discussion and just observing the group, one way to add value is to lead or facilitate the discussion.

You can propose what topics to discuss, the order they should be discussed in, and how much time should be allocated to each topic. When the group gets off track or goes on a tangent, you can bring the group’s focus back together.

Leading or facilitating the discussion establishes you as a group leader, which will leave a positive impression on the interviewer. However, because this role has so much responsibility and visibility, many people will try to take on this role.

Therefore, a group may have multiple leaders or facilitators. When trying to lead the group, make sure you remain respectful and do not interrupt other people when they are speaking.

Expand upon other people’s ideas

Another way to add value is to expand upon other people’s ideas. If a group member suggests a great idea or raises a good point, you can build upon it.

Wait until the group member has finished speaking and then jump in and compliment that person’s idea. Add more details or give more examples to make the idea more concrete.

Synthesize information

Another easy way to add value to the group is to synthesize information that other people have said. A synthesis is simply a reconciliation of different viewpoints and ideas together. This requires minimal effort, but adds tremendous value to the group.

What is the best way to synthesize information?

First, concisely summarize the major ideas that group members have made. Then, state what you like about each idea. Finally, propose an idea that consolidates the best points of each idea.

Synthesizing information does not require much thinking because you are simply repurposing the ideas of other people. This makes it an easy way to contribute to the group.

Keep track of time

Time goes by very quickly in a consulting group case interview. Therefore, a simple way to add value is to be a time keeper and make sure that the team is on track.

In the beginning of the discussion, you can propose a schedule or plan to make the most of the limited time that the group has. You can then volunteer to keep track of the time so that the group can finish discussing and deciding on everything that it needs to.

Play devil’s advocate

Another way to add value to the group is by playing devil’s advocate. You can help the team develop strong points and ideas by testing the team’s thinking and considering potential risks or downsides.

When the team has decided on an idea, bring up potential risks or downsides that the team should consider. This helps the team develop a more fully thought out answer or recommendation.

Be careful when playing devil’s advocate. You do not want to be attacking ideas or bringing them down. Instead, you want to be offering constructive feedback to test the idea and make it stronger.

The final way to add value to the group is to take notes for the team. By taking notes and keeping track of what other people are saying, you’ll be able to recall what has been discussed if any group members have questions.

This way of adding value to the group is not as recommended as the other strategies to add value.

Taking notes deprives you of opportunities to speak. Therefore, it is better to focus on understanding what other people are saying to identify opportunities to speak up rather than to focus on taking the best notes.

Consulting Group Case Interview Tips

Below are the seven biggest group case interview tips. Follow these tips to give yourself an edge over other candidates.

1. Treat your group members as teammates, not competition

While you may feel like you are competing against members of your group for a job offer, this is not the case. Multiple people or even all people in your group can receive job offers.

Rather than treating your group members like competition and trying to make yourself look better than them, treat your group members as teammates. You should think about the group case interview as your team versus the case, not you versus your teammates.

If you work well as a group and deliver an outstanding discussion or presentation, that increases the likelihood that members of the group will receive offers. If the group spends all of their time attacking each other’s comments and fighting for speaking time, the group will likely deliver a poor discussion or presentation, which makes everyone in the group look bad.

The key is to focus on delivering an outstanding result and not to focus on competing with other teammates.

2. Don’t speak too much and don’t speak too little

How much should you speak in a group case interview?

The problem with speaking too little during a group case interview is that you won’t have many opportunities to demonstrate your interpersonal, teamwork, and presentation skills. Interviewers may also think that you are shy and afraid of speaking in a group, qualities that are not ideal for a consultant.

The problem with speaking too much during a group case interview is that you may be seen as too aggressive and controlling. Speaking too much reflects poorly on you because you are taking away opportunities from other teammates to speak and contribute. You may come off as rude and disruptive if you interrupt people and talk over them.

If you were to rank order all of the members in your group by how much each person spoke, you would want to fall right in the middle. That is the perfect balance of speaking and listening.

3. Speak only if you are adding value to the group

Just because you speak a lot during a group case interview does not mean that you are doing well. The quality of what you are saying is much more important than the quantity.

If you are speaking a lot, but not adding that much value to the group, you will be seen as a poor teammate. A great teammate knows when to speak and when to listen.

Therefore, you should only speak if you are adding value to the group. Do not speak just to reach your participation quota.

4. Don’t interrupt or talk over people

The most common way to fail a group case interview is to come off as a jerk. Consultants work closely in small teams and no one wants to work with someone that is a jerk.

How do you avoid this?

First, don’t interrupt or talk over people. If someone is speaking, allow them to finish what they are saying before jumping in with your own thoughts. Second, don’t attack other people’s ideas. You may bring up your concerns and disagreements, but you should never blatantly tell someone that their idea is bad.

As long as you are a nice and respectful teammate, you will be miles ahead of anyone that is overly aggressive, pushy, or rude.

5. Involve other people

An easy way to demonstrate that you are a great teammate is to involve other people.

If you notice that someone has not spoken in a long time, ask them what their thoughts are on the discussion. If you notice that someone was cut off when speaking, ask them to finish their thoughts after the person interrupting them finishes what they are saying.

All of these actions require minimal effort, but add tremendous value to the group while making you look like a great teammate.

6. Don’t spend too much time reading independently

In the beginning of the group case interview, your group will be given materials on the case background, objective, and other information needed to solve the case. Your group members will likely spend the beginning of the group case interview reading the materials by themselves.

Do not spend too much time reading the material independently.

The purpose of the group case interview is to have discussions and work together as a group. The more time your group spends reading the material independently, the less time the group has to demonstrate interpersonal and teamwork skills.

7. You don’t need to have your idea or recommendation chosen

Remember that multiple or even all people in your group can receive job offers. Therefore, you do not need to have your own ideas or recommendations chosen in order to receive an offer.

Fighting or pushing too hard for your own ideas and recommendations may actually harm you. It may suggest that you are not open to other people’s ideas and not willing to support your teammates.

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 an 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 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 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 an 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 interview blurs. Online cases don’t just reduce the number of candidates to interview, but start directly replacing interviews.

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 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 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 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, 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 an 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 issue: 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, 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 consulting 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 cases 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 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 you to navigate a case just like you would a powerpoint! While you should obviously adopt a system that you are comfortable with, 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 skills 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 interview through your structure, and this is especially true of online 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 interview cases , 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. 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. 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.

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 cases, 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 cases. 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 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: 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 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 (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 itself 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 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 an 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 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 an 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 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 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 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 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 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 interview actually is. If your 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 interview, but more so.

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.

The Ultimate Guide to the Consulting Case Interview – With Examples

This guide, written by a former McKinsey consultant and Wharton MBA, breaks down the management consulting case interview into comprehensible parts with relevant, realistic examples at every turn.

While the consulting case study interview may seem daunting at first, most cases follow a typical song-and-dance. Once you get a hang of it, prepping feels much more manageable. The first part of this guide will give a broad overview of the case interview. The second part will break out the typical structure of an interviewee-led case. The last part will dive into each component, with tips and suggestions for preparing. Note that some firms may have their own specific case interview style. Be sure to familiarize yourself with your target firms’ interview processes before the time comes to recruit.

Case interviews involve tackling a business issue or problem faced by a company (the client). These interviews allow consulting firms to gauge candidates’ ability to perform the job. Specifically, firms are testing whether candidates can:

• Think in a structured and creative way
• Analyze and interpret new information
• Communicate persuasively and succinctly

Most firms conduct interviewee-led cases, as outlined in the guide below. In these cases, the candidate is expected to drive the case forward by asking the interviewer for data or information relevant to forming the recommendation. A few firms, most notably McKinsey, are interviewer-led, meaning that the interviewer will be the one guiding the discussion.

Below are a few common types of cases that you can expect to receive. Some cases can be several types all in one (lucky you!):

• Profitability - Determine cause for profit decline and / or ideas for increasing profit; you will rarely get a standalone profitability case – It will usually be rolled up in another case type
• Growth - consider strategies for company growth; could be through sales or market share
• Market Entry / New Business - Assess attractiveness of entering new geography / business / sector and method for entering
• Due Diligence / M&A - Assess attractiveness of purchasing / acquiring a company or business; client can be another company or a financial sponsor
• Competitive Response - Address a competitor’s recent action (e.g., new acquisition, change in pricing strategy)
• Non-Traditional - Similar to the other cases but the client (non-profit, NGO, education-focused entity) has different objectives than a typical corporate company

Case Interview Components

• Prompt: Interviewer reads aloud the case while the interviewee takes notes
• Recap: Interviewee provides a high-level summary of the case and confirms accuracy of information written
• Clarifying Questions: Interviewee asks 2-3 high-level questions
• Structuring (<2 minutes): Interviewee takes a few minutes create a roadmap for approaching the case
• Framework Presentation (2-3 minutes): Interviewee reviews the structure with the interviewer, who may have follow-up questions. Interviewee then moves the case forward by asking for additional information
• Brainstorming: Interviewee is expected to list out several solutions or ideas (e.g., cost drivers for an industry, ways to increase sales)
• Exhibits: Interviewee will be given data in forms such as graphs or charts and expected to provide high-level insights
• Math: Interviewee will be asked to perform a calculation with the new information or using data from the exhibits. Oftentimes, interviewee is not given enough information and must ask for the relevant data
• Synthesis and Recommendation (2-3 minutes) : Interviewee provides the answer first, then supporting facts from the case, and finally risks and next steps

Setup (2-3 minutes)

Prompt : The interviewer may be giving you A LOT of information - don’t write down everything verbatim. Jot down facts and figures, the client name, and the objective(s). If you miss something or don’t remember what a number means, you can ask after your recap.

• Prep: Have a friend read you several different case interview prompts and practice taking down notes. Create your own shorthand and learn how to recognize extraneous pieces of information

Recap : I always reference the client by name and start my recap with the objective(s) first, since this is the most important part of the case. The recap should be summarized, not verbatim, and you should be checking that the figures you wrote down are correct.

• Prep: Practice summarizing your notes out loud instead of repeating the case verbatim. Time yourself to make sure it’s <1 minute.

Clarifying Questions : Very detailed questions should be saved for the case. Clarifying questions are meant to help you with your structure or alleviate any confusion. Keep these at 2-3 questions. I usually ask questions pertaining to:

• Language/terminology - The interviewer won’t expect you to know the nuances of every industry or practice area. It is better you start off the case on the right footing by asking for clarifying definitions
• Goals/objectives - I always ask if there are other goals the company has in mind and, if relevant, specific financial targets or timeframe. Sometimes, the objective given is vague, so I will ask the interviewer to be more specific.
• Business model or geography - Very helpful for cases in niche industries; understanding geography can also prompt you to think about factors like labor cost or global competition
• Scope - To save you time from considering every possibility, you can ask whether the company is leaning towards one option or excluding a set of options completely
• Prep: Have a friend read you case prompts and then practice asking 2-3 clarifying questions on the fly. Try to think of them as you’re taking down notes and giving the recap. Are they helping you with your structuring or are you asking the first thing that pops into your head? Are they broad enough or overly detailed? Are there types of questions you should be asking but keep forgetting?

Framework (4-5 minutes)

Structuring (<2 minutes) : Do not use the word “framework” during the interview. I ask if I could have time to “gather my thoughts” when I am structuring. In your structure, you should have at least three but no more than five “buckets.” These are areas that you want to explore in order to solve the case. In each bucket, there should be at least three sub-bullets. Make sure there is no overlap between the buckets.

• Prep: Time yourself structuring your roadmaps. Be comfortable with recalling the different buckets you should be considering for each type of case and brainstorming sub-bullets for those buckets. It’s okay to go over two minutes when you first start, but as you get comfortable, make sure you are becoming more efficient. For example, as you become more familiar with the buckets, you don’t need to write down every example for the sub-bullets, they will become muscle memory as you recite them out loud. Review the suggested frameworks for the case and take note of whether there are vital topics you keep forgetting or whether there are unnecessary buckets you keep adding. There is no one “right” answer, but your roadmap should enable you to uncover the necessary information to make your recommendation.

Presenting: Introduce the high-level buckets first before diving into each one. You will want to “customize” your framework to the specific case you’re working on. This does not mean creating a custom framework for every single case. You can use the same topics for similar types of cases (but ensure that those topics are relevant - some cases sneakily rule out an entire topic to see if you are paying attention), but you need to make sure that you are using case-specific language and examples when you present. This shows that you are thinking about the specific problem, not just recycling a generic framework. After going through the structure, pause and ask if the interviewer has any questions. Then, give your hypothesis and state which bucket you want to start with by asking for data pertaining to that bucket and why you want it.

• Prep: Present your structures out loud and note whether you are rambling or being case-specific in your language. If you find that your presentation is too long, consider cutting down on the examples or explanations. Be succinct and say enough to get your point across. Don’t just move on to the next case if your presentation falls short. Keep practicing until you feel satisfied and make mental notes for the next case.

Interview “Questions” (10-20 minutes)

For each type of question, you are going to be doing the same things: answering the question, providing insights, conveying how it impacts your recommendation, and driving the case forward. Every time you have “answered” a question, you want to be thinking, “ What else do I need? What’s the logical path forward ?” The only way you can prepare for this is to run through entire cases! Remember, your framework is your friend. Refer back to it often if you don’t know where to go next.

Brainstorming : You will want to structure your ideas into MECE buckets. They can be fairly simple (financials vs. non-financials, external vs. internal, etc.). Similar to your framework, you will give a preview of the buckets first before going into the details of each and you will need to ensure that it is “custom” for your case. If a structure doesn’t naturally come to you, you can create a pseudo-structure by organizing how you will present your brainstorm. For example, you can state how many ideas you have from the onset or say that you will first go through the ideas first and then the associated risks.

This is a highly debated practice, but I always ask for a few seconds so I can think of a structure (they may say no). Don’t take more than 30 seconds because you can add to your buckets as you are presenting.

For non-technical brainstorms, be creative! For example, when interviewers asked about how to increase sales for a consumer-facing retail company, I would bring up TikTok campaigns and celebrity endorsements as a few ideas. Have fun with it!

Occasionally, interviewers will prod you with, “What else?” This does not always mean you didn’t give enough ideas. Sometimes it’s the opposite – they are looking to challenge you or see how you will react. Just roll with it - if you don’t have anything else, say so.

• Prep: Practice brainstorming for different types of prompts. Collect a bank of general ideas and solutions that can be customized for use across industries. Try to think of as many ideas as you can (four to six at the very least) and exercise that creative muscle. To help you with structuring, have a list of “easy” MECE buckets that you can pull out on the fly.

Exhibits : First, give an overview of the exhibit. As an example, for graphs say what the axes represent, tie it back to the case, and give your interpretation of those axes. This gives the interviewer a chance to course-correct if you misinterpreted the exhibit. Give some insight, even if it is low-hanging fruit, and tie it back to the case. There are three levels of insights for both exhibits and math:

• What the numbers say, patterns/trends (X is smaller than anticipated, Y is the largest driver)
• What the client should do (enter the market, cancel plans, plan for launch)
• What we should do next (reconsider something specific, research more data on X, move on to Y)

Oftentimes, exhibits will tie into a calculation. If you are given an exhibit with data that can be used to calculate more insightful information, tell the interviewer that you would like to make those calculations. The interviewer will lead you down that path regardless but it is more impressive if you call it out.

• Prep: Run through different types of exhibits and see how many insights from each level you can pull out. Practice anticipating what type of data you need next in order to move ahead in the case or whether you can/should calculate anything from the data given. Don’t be too insightful though – you only have a limited amount of time to run through the case.

Math : Before you start calculating anything, it is critical for you to confirm what you are solving for and that the information you wrote down is correct. SUPER IMPORTANT – answer the question that is being asked !!  If the interviewer is asking for the incremental profit from a certain strategy, you don’t want to calculate the total profit from the strategy. Active listening is so important!

As you know by now, structure is everything. Again, I always ask for a few seconds to organize my thoughts (the worst thing they can say is no). Set up the problem before you start calculating. This allows you to identify whether there is data missing. Walk the interviewer through your method and ask for missing data. You may need to make your own assumptions or estimates – be sure you can justify them.

If your method is off, the interviewer will usually guide you back to the right path. This saves you from wasting time calculating the incorrect answer. Be sure to pay attention when the interviewer is trying to coach you.

As you are solving the problem, walk the interviewer through each calculation and use math shortcuts as much as possible. Again, if you make a math error, the interviewer can stop you before you go down the entire path. Save time by only calculating what is important for the case and understanding what you can skip.

• Prep: Practice setting up the problem, walking the interviewer through your proposed method, and verbalizing the calculations out loud. On paper, make sure your calculations are being done neatly and not all over the place. Look for different math shortcuts and try them out. Not all of them will fit your style, but you might find new tricks. Track whether you are answering the right questions. Once again, active listening is critical to your candidacy. Once you have correctly solved the problem, make sure you are thinking about the, “So what?” Determine how that number impacts your recommendation and where you should go next.

Synthesis and Recommendation (2-3 minutes)

Again, I always ask for a few seconds to collect your thoughts (<30 secs). If the “CEO is already in the elevator,” they may say no. Have a definitive stance – start with your recommendation and then provide two to three supporting facts using data from the case.

Address risks and next steps (i.e., what is the required analysis/gameplan – this is like real life where the firm is trying to sell additional projects). Your recommendation should be <2 minutes. Frankly, the interviewer has most likely made a decision on your candidacy. Don’t ramble and try to finish strong.

The hardest part of this is pulling out the supporting data in a succinct way. Throughout the case, you should be jotting down notes. I tend to circle what I believe to be relevant supporting data. When you present it, don’t be too specific or granular. You want your recommendation to be punchy.

• Prep: Run through whole cases where you are tracking the relevant supporting data along the way. Time your recommendation and practice verbalizing the information concisely. Don’t forget the risks and next steps. I usually have a list of generic risks (e.g., competitor response, regulation, inaccurate projections) that I can “customize” on the off-chance I’m scrambling to think of some. Your next steps can be collecting additional data to support your recommendation or ways to address those risks.

Final Thoughts

• Your approach is more important than the solution – The interviewer is trying to understand how you think. Some cases have data that support recommendations in either direction. The key piece is that you are able to back your stance using the facts and data uncovered during the interview.
• Deadends are okay – There will be times when you make multiple requests for data and the interviewer does not have it. That’s perfectly fine! You can’t read the interviewer’s mind and the case could go in so many directions. Just look back at your framework to see where else you can proceed.
• Be coachable – It’s not the end of the world if your method is wrong or if you misinterpreted an exhibit. The interviewer wants to see that you are actively listening and can take feedback and improve. Don’t freak out! Stay calm! Listen to what the interviewer is trying to tell you.

This guide only scratches the surface of case interviews. The best way to prepare for case interviews is to get your reps in with entire cases. That way, you can identify your areas of weakness and be more precise with the drills. I can give you feedback and additional tips and tricks so that you are performing at your best on interview day.

It is an exercise that requires a logical approach to finding the problem and an appropriate solution.

A  case interview  is part of the job interview process in which you as the candidate have to analyze and solve a problematic business scenario while interacting with the interviewer. The case study is often based on a problem the interviewer has worked on in real life. This part of the interview is intended to be more of a dialogue. You will need to be proactive and ask questions when attempting to close in on the correct conclusion. Oftentimes, the consultant will attempt to guide you in the correct direction by asking questions himself.

An example question might be :​ The CEO of Deutsche Bank has become increasingly concerned about their declining profitability over the last 36 months and has asked you to determine the factors causing the decline as well as recommend a strategy to reverse this trend.

During the entire application process, you will partake in  up to six case interviews  in two rounds or more. This is dependent on the position you are applying for. Most case interviews have the same underlying structure. An individual case interview may take up to an hour and usually consists of four parts:

Case interviews have always been a part of management consulting interviews. Nowadays, also marketing, strategy, operations, or retail positions tend to use similar formats because they are a great tool to probe the quantitative and qualitative skills of an applicant . It allows interviewers to get a deeper insight into how you present yourself as a candidate and apply the limited amount of information given to you.

The reason for the prevalence of the case interview format in management consulting is that the topics and themes handled in most cases reflect conditions close to the reality of the day-to-day activities of a consultancy. It requires the applicant to  ask the right questions , apply  structured frameworks,  and think outside the box . As a consultant, you will spend a lot of time client-facing, and so soft skills are just as important as hard skills to the interviewer. The case interview allows hiring companies to ask the question "Would I be happy to put this candidate in front of a client?".​

Due to the scenario set up in a case interview, it is also a test of general business acumen. Many consultant projects will be in industries where the consultants aren't experts, especially junior consultants. This is normal, but to be effective as a consultant business acumen is an important foundation for consultants to maintain effective strategy recommendations. Companies pay consultants for their minds rather than their industry expertise.

A case interview has no “correct” or “standard” answer. There are often many solutions to a single case and in the end, what counts is your train of thought and how you got to your solution. The interviewer will evaluate you across five main areas:

1)  Problem-Solving Skills 

The interviewer will analyze your ability to identify problems , isolate causes, and prioritize issues. During a case interview, you will be presented with a wide range of relevant and irrelevant data pieces. You must know how to use this data to make your recommendations and you have to prove that you are able to construct a logical argumentation without rushing to conclusions based on insufficient evidence.

2)  Creativity and Business Sense Skills 

As a consulting candidate, you should know the basic business concepts as well as show a certain amount of business sense and creativity. If the interviewer asks you to find innovative ideas to increase the profitability of a hotel chain, you will have to come up with a range of ideas that make business sense. You are not expected to have deep knowledge of the hospitality industry, but to be able to ask relevant and insightful questions on the aspects important for you to solve the client’s issue at hand.

3)  Structure 

Maintaining a structure means that you solve the question with a clear step-by-step approach that you communicate actively with your interviewer. A good structure is the most important part of a case interview, as it is the underlying base of your whole approach and argumentation. It is also the main reason why candidates fail their case interviews. A common mistake that candidates make is that they try to apply standardized frameworks to any case they are given. Instead, you should solve each case by creating a framework specifically tailored to its needs – as you would do as a consultant on the job. Practice your structure with our Structuring Drills .

4)  Math Skills 

As a consultant, part of your job is number-crunching and interpreting data. Therefore, it is important that you have a good feeling for numbers and have great mental math skills. You should be able to perform simple calculations in your sleep. You can practice your math skills with our Mental Math Tool .

5)  Communication Skills 

In times of digitalization, soft skills become more and more important for management consultants. On the job, you will be in contact with high-level CEOs, clients, partners, and colleagues. Strong communication is crucial for you to get your work done efficiently. Thus, your interviewer will pay close attention to the way you communicate and present yourself during your conversation. Always be professional, answer concisely, and communicate the key message first (see Pyramid Principle ).

First and Second-Round Interviews 

While the format of the first and second-round interviews stays the same, the seniority level of the interviewer differs . The person interviewing you in the first round is usually more junior, having up to four years of consulting experience (Associates or Engagement Managers). The second round is led by Partners who have more than ten years of experience and tend to drill you to understand how you cope with challenges. Therefore, second rounds are perceived as more difficult by candidates. Since partners have a stronger voice when discussing an applicant, your performance during the second round of case interviews carries also more weight. For more information on the different positions, please read McKinsey Hierarchy: The Different Position Levels .

Candidate- and Interviewer-Led Case Interviews

In candidate-led cases, the interviewer expects the candidate to lead him/her through the case. As a candidate, you can do so by asking relevant questions, and by developing and testing your hypotheses. Candidate-led cases are the most common  types of cases . You will encounter them at the majority of the big consulting firms such as BCG, Bain, and occasionally at McKinsey.

Interviewer-led cases are most frequently used at McKinsey. As the title suggests, the interviewer’s guidance through the case interview is firmer.

You can find more information on the two different interview styles in our BootCamp article: Interviewer-Led vs. Candidate-Led .

In the following, you can find some examples of initial case interview questions :

Bain Case: Old Winery You inherit an old winery, the Old Winery, from your grandfather. Since you have little knowledge about wine cultivation, you don't want to run the winery operationally, but you find the idea of owning a winery exciting. However, your plan is to breathe new life into the winery. Read the entire case .

Deloitte Case: Footloose Duraflex is a German shoe manufacturer with an annual turnover of approximately €1 billion. Your largest sales market has always been the boot market. In this market, you compete with three other main competitors. Management is asking you for advice. Read the entire case .

Roland Berger Case: Onlinestar Onlinestar, an online retailer specializing in furniture and garden products (core business), has experienced significant growth in recent years due to an expansion of its product portfolio.

Case interview frameworks are the perfect tool to structure your thoughts during the interview. They help you break down a problem into its components so that you can systematically and methodically navigate through the case and the business problem. This approach will convince your interviewer that you can apply your skills from the case interview to the job as well.

A framework can help you solve a business problem in a case interview in a structured and organized manner. To determine which framework is most suitable for the given case, you should be familiar with the most common case types. Our coaches Guennael and Vlad explain their approaches:

What does a framework really need to accomplish? Essentially, three things:

First , it must be MECE (Mutually Exclusive, Collectively Exhaustive); second , it must help you systematically and methodically approach the case so that you not only find the best answer; third , it must convince your interlocutor that your success is repeatable and that you will solve this case and the next and the one after that.

When preparing for my BCG interview, I ultimately relied on just two framework concepts, which I then adapted to the respective case: First, a version of the profitability case (Profit = Revenue - Costs and Revenue = Price x Quantity) ; second, a basic version of: Product, Price, Customer, Competition, Company).

Are these two framework models optimal in every case? No, they are not. Did they serve their purpose? I used them in more than 10 practice cases with former BCG employees as well as in my 5 BCG cases... and I succeeded, that's for sure :) I would even argue that every case can be solved using one or both of these methods . Learn them, keep them in your pocket, and be ready to use them. If you find something better, great! But I'd prefer you start with an "okay" framework and focus on solving the problem , rather than spending the first 30 seconds of the case trying to find the "perfect" framework, failing, and feeling forced to think on the fly at the beginning of the solution process.

There is no universally applicable structure . You should have some patterns in mind for specific types of cases, but you should adjust them depending on the case:

Additional details of the case

Below you'll find a list of the most common case types and some general recommendations for structuring :

Market Sizing - Structuring from the supply or demand side. Structuring based on a formula or a issue tree .

Profitability - Basic profitability framework. Consider different revenue streams and the product mix.

Market Context (market entry, new product, acquisition, etc.). Always start with the big picture "market". Conclude with a specific strategy to achieve the case objective (e.g., "market entry strategy" - for market entry. "Exit strategy" for the PE case. "Go-to-market strategy" for a new product). Structure it as if you were defining the workflows for the real project.

Operational Mathematical Problem (e.g., Should we increase the speed of an elevator or simply buy a second one? How should we reduce queues? Etc.) - Structuring as a process/value chain, with inputs, processes, and outputs.

Cost Reduction - here are some recommendations for structuring:

Structuring:

How do the costs break down and what are the largest costs?

Benchmarking the largest costs to identify improvement potential

Process improvements to achieve the benchmarks

Costs and benefits of the proposed initiatives

The key concepts you must learn:

Internal/external benchmarking

Core processes (usually optimized) and supporting processes (usually trimmed)

Mathematical structures (frequency of operations * time per operation)

Other useful structures (e.g., People - Process - Technology)

Evaluation - Pure financial structure with cash flows, growth rate, WACC / Hurdle Rate, etc.

Synergies - Revenue synergies (price, quantity, mix) and cost synergies (value chain).

Social/economic cases (e.g., How can the quality of life in the city be improved? How can museum revenue be increased?) - significant variability.

Practice 3-5 social cases before the interview. Additionally, there are s everal useful framework concepts that you can apply in the middle of the case to find the cause of a problem. For example:

People - Processes - Technologies

Capacity - Utilization - Production rate

Product - Distribution - Marketing - Price

Value-based pricing - competition-based pricing - cost-based pricing

You will learn these frameworks while solving cases. It is useful to have a set of them in mind to quickly identify the root cause .

To be able to address specific questions in case interviews, it is important to develop your own frameworks . Our expert Benjamin has valuable tips on this.

(Almost) Never use a standard framework from the books . In strategy consulting, the goal is to assist clients facing unique problems with a customized solution. It's unlikely that you can force your approach into a standard framework.

Put yourself in your client's shoes and show empathy for the issues. This way, it becomes much easier for you to understand what the key issues are that you need to consider when formulating a recommendation, and you can ensure that you don't forget anything. I always ask myself, "What would I do if this were my company and my own problem? What do I need to know/understand to make a decision?"

Ensure that every topic you want to address is relevant to the final recommendation. A simple check is to ask yourself, "If I spend time on this specific topic and get some answers to my questions (e.g., market size, competition, etc.), will this provide useful elements for the final recommendation given my client's issues ?" If the answer is no, then you should skip this subtopic.

Practice a lot! The above tips come from my own experience with building MECE structures , but keep in mind that it takes a lot of practice to achieve satisfactory performance here.

1. Learn the Theory By reading this article, you've already taken the first step to understanding what case interviews are all about. Well done! You can now take it a step further by learning the theory you need to solve the cases. In general, you should learn how to :

Identify your case type (e.g., market sizing , market entry , profitability , growth )

Structure your thoughts (e.g., issue tree , MECE , pyramid principle )

Use business analysis tools (e.g., ABC analysis , break-even analysis , benchmarking )

Define common business terms (e.g., NPV , CAGR , fixed and variable costs )

In our Case Interview Basics, you'll find all the necessary fundamentals.

2. Develop Your Business Intuition Step by Step

Since you need to have a good business sense to successfully complete your case interview, you should invest some time beforehand to gradually build up your business intuition. The earlier you start, the easier it will become. Make it a habit to regularly read business publications and magazines. You can read new releases from McKinsey, Bain, and BCG, or find other sources that appeal to you. Try to acquire a basic understanding of economics, strategy, and industries, such as retail, airlines, telecommunications, banking, natural resources, and technology.

3. Update Your Math Skills

For all case interviews, you must calculate without a calculator. Therefore, refreshing your mental math skills should be a regular part of your daily preparation plan. Practice until you feel one hundred percent comfortable with the basic skills of addition, subtraction, division, multiplication, and growth rate calculations in your head. Read our article on Fast Math and use our mental math tool to train your performance. When confronted with a math problem in your case interview, this will significantly reduce the pressure.

Knowing shortcuts for a variety of calculations can simplify mathematical problems. For example, break down complex mathematical problems into several small operations:

97 x 53 = (100 - 3) x (50 + 3) = 5000 + 300 - 150 - 9 = 5141

4. Practice Makes Perfect

Take a look at our extensive case library , which prepares you for all possible case types. Our case library includes cases that have been used in past case interviews. Solving cases on your own can give you a first sense of what to expect in the case interview. However, the only way to improve your skills to successfully pass the interview is to put yourself in a case interview situation. Find candidates to practice with and practice regularly. The more feedback you can get, the better. This will help you improve.

PrepLounge offers the world's largest case interview community. Simply schedule or accept a practice interview with other candidates on our meeting board .

Here's how it works:

Schedule: Once you and your case partner confirm the practice interview on the meeting board, the meeting is set and will be visible on your dashboard.

Communication: We recommend contacting your case partner directly to discuss communication methods and case preferences during the interview.

Interview: During the back-to-back meeting, you and your case partner take turns playing the roles of both interviewer and interviewee. Don't neglect the part of the session where you play the role of the interviewer. This allows you to identify important points and adjust your approach accordingly.

Case: By default, two PrepLounge cases are randomly selected. However, you can exchange them and choose one of our over 180 cases or use your own case.

Feedback: This is the most important part of your practice interview as it helps improve your case performance. Please provide your interview partner with constructive feedback, just as you would expect from them.

5. Seek Support from Coaches

To make your case interview preparation as effective as possible, we also recommend investing in coaching sessions with experienced top consultants. Our experience shows that this investment pays off, as it significantly increases your chances of receiving an offer for your dream job (by four times, to be exact). Our coachesknow exactly what interviewers want and can work with you on every aspect of your case performance, whether it's structuring, personal suitability, confidence, or communication. Furthermore, they can provide you with valuable networking tips and help you get a referral.

We provide you with a transparent list of all case interview coaches , including their professional and educational background, top skills, individual approaches, ratings, and recommendation rates. This way, you can individually select the perfect expert for your coaching sessions . Additionally, you can benefit from CoachingPlus , which includes a premium membership and a generous discount (compared to individual coaching sessions).

6. Learn and Track Your Progress

You can do as many cases as you want. If you don't learn from them, you won't improve your case performance. That's why you should do the following: At the end of each case you complete, whether on your own, with a case partner, or with an expert, write down in your own words what mistakes you made and what you learned. Repeat the case after a few days and apply what you've learned to ensure you're making progress. Tracking your progress motivates you and ensures you don't repeat the same mistakes.

7. Don't Forget the Personal Fit

No matter how well you master the case, if you don't personally fit into the company, you won't get the job offer. Ultimately, consulting is a "people's business" that involves teamwork and a lot of time with your colleagues. To master the part of the interview that focuses on personal suitability, it's important to understand what an interviewer is looking for in a candidate to decide if they fit into the company personally. Typically, the interviewer has three primary questions in mind.

Next, you should learn how to convey to your interviewer that you fit what they're looking for. Practice your answers to the personal fit with other candidates or experts:

Why consulting?

Why company X?

Why should we hire you?

Tell me about yourself!

Give me an example of when you led a group to achieve a difficult goal!

Find more frequently asked questions in stress question mode.

8. Train Confidence

The more you practice, the more confident you will feel. However, feeling confident isn't the same as appearing confident. Sometimes you can come across as insecure without realizing it. This can be due to small habits in your communication style. Therefore, ask your PrepLounge case partner or expert to consider your verbal and non-verbal communication and provide feedback on your confidence or insecurity . Focus on the following aspects during practice:

• The tone of your voice. A monotone voice or speaking too quickly gives an impression of insecurity and poor communication style. To avoid this, it's helpful to listen to podcasts of great speakers for 30-60 minutes a day. After a few days, you'll start speaking in a similar manner as you adopt their communication style.
• Smile. A smile can be a powerful way to show that you're enjoying the conversation and not afraid. You can also force a smile (naturally, not too much) if you get feedback that you appear too serious.
• Eye contact. You don't need to continuously stare into the interviewer's eyes during the conversation, but you shouldn't look away when they ask you something.
• Ability to break the ice. Confident people aren't afraid to engage in small talk with interviewers. Silence creates less connection and can be seen as a sign of lack of confidence.
• Posture. You should try to sit upright most of the time on your chair. Leaning too much towards your interviewer can be interpreted as lack of confidence.

9. Take Breaks

Overall, based on our experience with other case partners, you should prepare for an average of 50 hours over a period of up to 6 weeks and practice daily. This can be exhausting, and we know that many candidates struggle with motivation and concentration, especially after an intense case preparation period. This is usually because they forget to incorporate regular breaks into their preparation plan. Professional athletes, for example, always take time to rest and allow their muscles to regenerate. You should treat your brain muscles the same way. A good strategy is to develop an evening and morning routine that allows you to relax and increase your energy level for the preparation period during the day. Here are some examples of what you can do:

15-20 minutes of exercise in the evening or morning

A cold shower in the morning

Meditation or journal writing

Define three important things for the next day and allocate time for all activities, prioritizing the most important ones first

No social media for an hour after waking up and before going to bed

Get enough sleep (at least 7 hours)

Take breaks between each case or intensive case practice and do something completely different (e.g., workout, play video games)

Step 1: Listen actively and take notes. Write down every piece of information, especially numerical data .

Step 2: Restate the question. Pause, paraphrase, and make sure you understand the problem statement by confirming with the interviewer.

Step 3: Clarify the objectives and identify the problem. Ask specific questions and double-check on objectives. Make sure you completely understand the problem.

Step 4: Write out your structure. Ask your interviewer for a minute to prepare your structure and organize your notes. Identify your case type and use an issue tree to customize your structure. The branches of your issue tree should be MECE.

Step 5: State your hypothesis. Now that you have set up the issue tree, your task is to test each branch to see if it is the root cause of the problem. Where to begin? A hypothesis based on an educated guess helps here.  (e.g. "Since you have mentioned that revenues are more or less flat, my hypothesis is that the problem is mostly driven by the cost side of the business. If it is okay with you, I will start by […]")

Step 6: Think out loud. Sharing your thoughts allows the interviewer to interact. Refine or rebuild your hypothesis as you find out more.

Step 7: Gather more data in order to test your hypothesis. Proactively ask for relevant data and always segment it (e.g. using the ABC analysis ). Try to evaluate whether trends have been company-specific or industry-wide.

Step 8: Dig deeper while staying structured (MECE!) throughout the case. Always refer to the structure you have set up at the beginning of the case, but be flexible as the case evolves. If you conclude that your hypothesis is false, eliminate that branch and go to the next one. Summarize findings when switching major branches. If your test confirms your hypothesis, go deeper into that branch, and drill down to the lower levels until you identify all proven root-causes.

Step 9: Choose a recommendation and use the Pyramid Principle to structure your conclusion. Ask for a minute to gather your thoughts and then state your recommendation. You need to deliver a one minute, top-down, concise, structured, clear, and fact-based summary of your findings.

Step 10: Stand by your conclusion. Your interviewer will likely challenge your recommendation (either to see if you can handle pressure or to assess if you really believe in what you are saying).

1. Focus on the task at hand 

Don’t think too much about the approach your interviewer is taking. It should not matter much if the conversation is interviewer- or candidate-led. If you go into your interview with a profound understanding of how to handle even a difficult case, the format of the interview should not be an issue. Keep a cool head and structure your thoughts.

2. Ask the right questions 

At the beginning of the case, your interviewer will present you with the situation of the client. Don’t rush into the analysis without developing a deep understanding of the problem first. Ask your interviewer questions to clarify the case. This is expected behavior that also takes place later with the client. Make sure you understand what the  business model  and your  objective  in the respective case are (regarding both money and the timeline). If there are any other possible limitations you are unsure about, ask your interviewer in a concise way. Asking unnecessary questions will raise doubts about your ability to work efficiently under pressure.

3. Buy time with repetitions 

A common trick consultants use is the  repeating of facts or overall goals . By doing this, you are showing a fundamental comprehension of the case and are emitting an aura of control, gradually heading towards a solution. This technique can give you more time to think. Articulating the facts of the case can also be a source of clarity and allow you to form solutions more quickly.

4. Only form a hypothesis with sufficient information 

Do not state a hypothesis at the beginning, a stage in which you may still have incomplete information. Get a good sense of the case’s environment and ask sensible follow-up questions . Only then frame a structure and formulate a hypothesis.

5. Utilize data for your analysis 

Taking wild guesses is a death sentence for your case interview. Make sure your claims are backed up by the facts, and remain calm when presented with new information. Consultancies will closely observe how you  make use of new data and incorporate it into your hypothesis .

6. Take clear notes 

Taking  structured notes  is a highly underrated skill when dealing with a case. Making sure your notes are coherent and clear will make your thoughts easy to navigate and ensure you do not lose your footing during the interview.

• Place your sheet horizontally to maximize your space, and jot down the case’s  key question on the left side of the page. This way you will never lose sight of the main objective . The remaining portion will be dedicated to the issue tree, with your hypothesis included above the issue tree.
• Make sure that you highlight key pieces of information that add substance to your hypothesis.
• When it comes to calculations , use a separate page, but practice having it organized in case you need to go back through your assumptions or calculations.
• Try to limit the number of pages you use to a  maximum of three sheets . Otherwise, you will stress yourself out while trying to find what you are looking for.

7. Structure is key 

The most important aspect of a case interview is having a good structure. You can structure your case by following these four steps:

• Craft an issue tree as the overall foundation for your structure. This is a customizable framework used to analyze the root causes of problems in a case. It helps you to break a complex problem down into its components.
• Make sure that your issue tree is MECE to avoid inefficient dependencies between branches that will slow down your analysis. MECE is a way of segmenting information into sub-elements that are mutually exclusive and collectively exhaustive. 
• Prioritize and concentrate on high impact issues of your issue tree that will create value for your client. Always make sure you explain the reasons behind your choices to the interviewer.
• Use the Pyramid Principle to structure your conclusion , a three-step structure to present your synthesis in an effective and convincing manner. First, state the recommendation (What?). Second, provide three reasons supported by data (Why?). Third, provide information on how to implement the recommendation (How?). 

To practice your structure, you can use our Structuring Drills.

8. Don't force-fit frameworks

Standard frameworks can be a source of inspiration, but should never be force-fitted to a case. They are very stiff and do not allow room for customization . If you use pre-defined frameworks, you run the risk of missing important elements of the specific problem you are trying to solve. A consultant would not just force-fit frameworks to their specific client’s problem, so you should not do this in your case interview, either. Each case is unique and requires an individually customized framework that is MECE as well as adapted to the problem you are trying to solve, the company, and the industry.

9. Don’t panic if you get stuck 

If you ever get stuck, don’t freak out – it happens. What counts is how you deal with the situation. Here is what you can do:

• Take a deep breath  or a sip of water if you have a glass of water nearby.
• Take a moment to grasp the big picture , to recap what you have learned so far and what you still need to find out to address the main question at hand.
• Outline how these sub-questions can be answered , and what kind of data or information you will need to do that.
• Double-check whether data or information provided by the interviewer at an earlier stage is now getting new relevance.
• Think out loud and take the interviewer along with your thinking process. If you are puzzled by some obvious contradiction, actively discuss this with your interviewer. Oftentimes, an interviewer will wait for you to explicitly verbalize your confusion before gently guiding you.

10. Sometimes there is no clear answer 

Oftentimes, a case interview has no “correct” or “standard” answer. The case may encompass you  exploring the issues and walking down several paths . There are often many solutions to a single case that may differ from the interviewer’s expectations. In the end, what counts is your  train of thought and how you got to your solution . You are not expected to know everything about business, but demonstrate a logical judgment and a good approach to solve problems.

Nevertheless, you should always give a clear recommendation at the end of the interview, when the interviewer will ask for your conclusion. The trick is to use supporting arguments based on what you have learned during the analysis, to point out limitations, and to also highlight additional areas to explore to confirm that your current understanding is the right one.

11. Engage the interviewer 

The interview should be a dialogue, so make sure to engage the interviewer and demonstrate not only your business judgment, but also your communication and people skills . This gives the first insight into how you might interact with future clients and colleagues. How can you do that?

• Explain. Share your thought process with the interviewer, and always let them know what your next steps are.
• Listen. During your case interview, the interviewer will usually give you hints and steer you in a direction. Notice that! If they ask a specific question, e.g. “Name three points about…”, answering in two or five points will mean that you didn’t pay attention.
• Ask questions. Create a discussion, initiate small talk, and use your chance to make a positive connection with the interviewer, especially at the end of every interview when you get to ask final questions. Find a point in common and try to stand out. Here is a list of the best questions to ask at the end of an interview .  

12. Be confident 

You don’t necessarily need to be extroverted to be a top management consultant, but you need to be confident. Consulting is a people job as much as it is an analytical job. It is important for the client to feel that you know what you are doing. Thus, this is something the interviewer will take into consideration. Here are five things you can do during the interview to come across as more confident:

• Try to enjoy the interview by focusing on the challenge, the satisfaction it brings you when you solve the case, and the joy of sharing your life experiences with someone else. If you have fun, chances are high that the interviewer has fun, as well.
• Find your own style and don’t try to pretend to be someone that you are not. It is fine if you are not the most outgoing person. Just be genuine!
• Sit up straight , but don’t be too stiff. Push your back against the back of the seat and don’t just sit on the edge of the chair.
• Make eye contact , but don’t stare, either.
• Speak in a clear , calm, and unrushed manner. Don't mumble or whisper, but equally don't shout. Think before you speak!

13. When in doubt, reschedule 

If you’re not feeling confident about your chances, don’t hesitate to reschedule. If you take this course of action, take a few things into consideration. Make sure to suggest an alternative day and avoid rescheduling multiple times at all costs. The consultancy will be grateful for you to suggest an immediate alternative. Try to be transparent as to why you are rescheduling without going too deeply into details. However, rescheduling should only be used as a last resort.

Consulting group case interview: what to expect and how to prepare.

As you probably know, the leading consulting firms use case interviews to evaluate job applicants before extending offers. Some consulting firms use a group case interview as part of the evaluation process. If you have a group case interview coming up you are probably thinking, “How can I set myself up to do well?” In this article, we provide some advice on how to succeed in a group case interview.

What is a group case interview?

A group case interview includes a few candidates being interviewed simultaneously within the same room, with the same interview and with the same case problem. Candidates are usually given copies of the case to read. A group case interview usually takes place after initial 1-on-1 evaluations are completed, like resume screening and the PST. So only the best candidates would generally be attending a group case interview.

For example, if you are going through consulting case interview recruitment process during an MBA , consulting firms will usually do first-round interviews on campus. This will allow firms to select the best few candidates to invite for second-round interviews, which may include a group case interview. Some firms may do the opposite and some regions within firms may do things differently. For example, in the US the group interview usually is the first interview.

The case usually includes a business scenario where a client is facing a problem. Reading of the case may be followed by a group discussion or by group discussion and a solution presentation.

Why do consulting firms use group case interviews?

So, why do consulting firms use group case interviews. The same as 1-on-1 case interviews, a group case interview helps consulting firms assess critical thinking, analytic skill, and communication skills. However, in addition, a group case interview also helps firms assess team work and leadership skills.

Firms also tend to be believe some degree paths de-emphasize teamwork and communication. They use the group case interview to test for these skills. The group case interview is testing to see how a case would be solved while managing conflicting opinions and strong personalities.

The most important advice: treat candidates like teammates

Now, the most important advice we can give you for a group case interview is to treat the other candidates like your teammates. In other words, interact with other candidates as you would with your colleagues on a real consulting engagement.

One of the key things to understand is that a group case interview is not a zero-sum game. You should not be competing against other candidates. During a group case interview, the interviewer will be evaluating how you will work with your colleagues and clients, so keep this in mind as you interact with other candidates during a group discussion.

This is one of the most common mistakes we see candidates make during a group case interview. Candidates often view it as a competition and, as a result, interviewers view such candidates as a bad fit and someone who can’t be a good team player. Your goal should be to help the team solve the case, help include opinions from all members, build on what has been said and find ways to help the team. If you solve the case and the whole team fails and ends up looking poorly, it is not a good reflection on you.

If someone says something incorrect or something you think is stupid respond in a way you would respond if you already joined the firm and were working on a real project with other consultants at the firm. Be professional, respectful and watch out for the best interests of the firm and the client. On the other hand, if someone says something spot-on, be the first to point group’s attention to it and build on it. If you say something that turns out to be wrong, acknowledge your mistake and move on.

Case Interview: Complete Prep Guide

Welcome to our preparation tips for case interviews!  Whether you are just curious about case interviews or are planning to apply for consulting internships or full-time jobs, these tips and resources will help you feel more prepared and confident.

A case interview is a role playing exercise in which an employer assesses how logically and persuasively you can present a case. Rather than seeing if you get the “correct” answer, the objective is to evaluate your thought process. ( Adapted with permission from Case In Point: Complete Case Interview Preparation by Marc Cosentino). 

Case interviews are very commonly used in the interview process for consulting firms and companies in similar industries. In the case interview, you will typically be given a business problem and then asked to solve it in a structured way. Learning this structure takes preparation and practice. You can learn more and practice using the resources listed below.  

Why are Case Interviews Used?

Case interviews allow employers to test and evaluate the following skills:

• Analytical skills and logical ability to solve problems
• Structure and thought process
• Ability to ask for relevant data/information
• Tolerance for ambiguity and data overload
• Poise and communication skills under pressure and in front of a client

How can I prepare for Case Interviews?

How to Prepare for the Group Interview

April 19, 2017 

If you are interested in applying to Counseling@Northwestern, there are many important application items to complete, including your statement of purpose, letters of recommendation, and supplemental essays. However, there is one aspect of the process that is sometimes forgotten: To be admitted into the program, applicants must participate in and complete a group interview. This unique aspect of the application process can cause confusion or even anxiety for some applicants. Here, we will go through why we conduct the group interview, what to expect, and tips for excelling during this important part of the admissions process.

Why does Counseling@Northwestern conduct the group interview?

The group interview is an integral part of the review process to determine if you are a fit for the program and whether the program is a good fit for your professional goals. Faculty members and selected supervisors will be able to evaluate your observable traits, such as your ability to cultivate relationships, while you are challenged to behave as if you were already enrolled in the program and participating in a live class session. CACREP—the Council for Accreditation of Counseling and Related Educational Programs—also requires that students demonstrate group interactions before receiving an admissions decision. Counseling@Northwestern’s group interview is central to its accreditation and admissions requirements.

What should I expect during the group interview?

The group interview consists of four sections:

• Questions for applicants:  A faculty member or supervisor will ask each applicant five to six questions, which may be fill-in-the-blank, hypothetical, or open-ended. For example, a faculty member may ask, “What is the greatest adversity you have overcome in your life?” You will then be challenged to respond in a way that represents your unique characteristics that demonstrate your counselor candidacy.
• Case studies:  All applicants in the group interview will be given a brief case study or two, depending on time, illustrating complex client problems or situations. You will then work with each other to discuss how to best handle the situation and come to a solution. Sometimes you will be asked to discuss your reaction to the case. There are many questions that can be asked during a case study.
• Final Reflections:  During this portion of the interview, you will be asked to discuss something that had an impact on you during the interview. This could be something a fellow interviewee said or did, or something you realized about yourself. This will assess if you have the proper reflection skills needed to be an effective counselor.
• Questions for the interviewer:  At the end of the process, you will have the opportunity to ask the interviewers questions about the interview, the Counseling@Northwestern program, or about counseling-related issues and ideas. This section gives faculty an idea of your analytical and introspective skills.

What can I do to excel during the group interview?

The interview will take place in the online classroom, so a stable internet connection is a necessity. Make sure to conduct the interview in a quiet environment, free of distractions and outside noise. It is important that you choose a location that is conducive to concentration and allows you to feel focused and comfortable. Faculty members are looking for candidates who have superior listening and communication skills. They will also be focused on looking at each candidate’s self-awareness, empathy, and appropriate self-reflection. Lastly, be  you . Faculty interviewers value authenticity. All of these traits are essential to being a quality counselor.

Once the group interview is complete, you will receive a decision on your application within one to two weeks.  

The group interview can sometimes be a point of stress for applicants. However, the most important thing to remember is that the interview is a time for you to shine, not to hold back because of nerves. Faculty members are excited to get to know you. Take advantage of this opportunity to present yourself in the best light possible.

If you have questions about the group interview, please follow up with your admissions counselor.

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

The PwC Case Interview (Including Strategy&) – A Complete Guide

• Last Updated January, 2024

PwC is an accounting firm with a huge consulting arm. Its consulting business is as large as those of Bain, BCG, and McKinsey combined. If you’re interested in landing a job in the consulting industry, it’s a great firm to apply to because its business combines strategy consulting (Strategy&) as well as business transformation/implementation (PwC).

If you want to know more about PwC consulting and Strategy&, you’re in the right place! In this article, we’ll discuss:

• An overview of PwC Consulting and Strategy&.
• The PwC recruitment process.
• The PwC case interview.
• The behavioral/fit interview.
• The PwC group case.
• The PwC individual presentation.
• Our 5 tips for preparing for PwC and Strategy& interviews.

PwC Consulting and Strategy & - An Overview

5 Tips for Preparing for PwC and Strategy & Interview

PwC employs over a quarter of a million people in 155 countries worldwide. Its operations are divided into two parts: Trust Solutions and Consulting Solutions. Trust Solutions focuses on its accounting and tax services. PwC Consulting Solutions help a broad spectrum of clients navigate complex business issues by leveraging PwC’s significant experience and range of capabilities.

Client case studies include:

• helping TransRe adopt an enterprise resource planning system to collect and manage data, offering insight and improved decision-making.
• supporting Chipotle to implement a loyalty program to improve customer relationships, build loyalty, and drive business growth.
• providing pro bono consulting to charity The Trevor Project to strengthen its technological capabilities and optimize its volunteer recruitment process.

How does PwC Consulting differ from Strategy&?

In 2014, PwC acquired Booz & Co., the commercial arm of consulting firm Booz Allen Hamilton, and renamed it Strategy&. While PwC Consulting focuses on typical management consulting cases and implementation projects, Strategy& specializes in strategy consulting.

Set up by PwC to attempt to compete with McKinsey, Bain, and BCG, Strategy& has over 3,000 consultants helping businesses shape their future strategies. Strategy& focuses on creating competitive advantage by “developing corporate and business unit strategies and building differentiating capabilities that outperform the competition.” ( Source: PwC )

Implementation of those strategies is handed over to PwC consulting teams. If you join PwC’s management consulting team you will, “help clients translate strategy into execution, closing the gap between ideas and outcomes, to transform the organization and achieve tangible business results.” (Source: PwC)

Like most other Big 4 firms (EY, Deloitte, and KPMG), the PwC recruitment process has multiple stages:

Stage 1: The PwC Application

For entry-level recruitment, the first stage of the PwC process is to submit an application form for the particular roles you’re interested in. You can search for your school’s application deadline on PwC’s interactive campus map. If you can’t find your school or have recently graduated, you should submit by their September deadline. You’ll be asked to pick your top 2 preferred office locations and you’ll need to submit a resume.

To learn more about how to write a stellar consulting resume, read Consulting Resume: Everything You Need to Know .

Stage 2: The PwC Online Test

A few hours after you’ve submitted your application, PwC will send you an assessment to complete via email. You have to complete the online test within 3 calendar days so it’s worth thinking about that when applying. The PwC online test is a series of games-based assessments to measure cognitive ability, behavioral preferences, and verbal and numerical reasoning.

Learn more by reading PwC Online Test .

Stage 3: The PwC Interview

If you successfully pass the online test, PwC will invite you to a series of interviews. These will include a case interview and behavioral interview and may include a group case and an individual presentation. The first of these interviews is sometimes conducted as a video interview where you’ll record your answers to a range of questions and case studies. Group interviews have traditionally been part of the recruiting process for sophomore consulting internship candidates and select other groups. It’s a good idea to clarify with your recruiting contact what types of interviews you’ll have.

In the past, the bulk of the remaining interviews, group, or individual activities took place during an assessment day. However, for 2021-22 recruitment, PwC US is moving to virtual interviewing. For Consulting Services, you’ll face two virtual, live interviews back-to-back. If you move forward in the process, there may be a final additional  interview.

Nail the case & fit interview with strategies from former MBB Interviewers that have helped 89.6% of our clients pass the case interview.

The case interview process is similar for both PwC Consulting Services and Strategy&. The case interviews are both candidate-led, which means you’ll be responsible for deciding what analysis you want to do and what the approach should be.

The PwC case interviews for Consulting Services applicants typically focus on profit optimization, cost optimization, and market sizing. For example, a recent candidate was asked to “Run me through a market sizing estimate of the iPhone market in Asia.”

For a breakdown of precisely what each of these types is, read Case Interview Types: Master Common Ones Before Your Interview .

The PwC Strategy& case interview includes more strategy-focused cases (such as make-vs-buy decisions, new product introduction, M&A, etc.), but how you tackle a case interview is the same no matter which area you’re applying for.

Following this 4-step model gives you the best chance for success:

• Understand the question . Make sure you understand what it is you’re being asked to do. Repeat back to the interviewing team what exactly you think the task is so they can correct you if necessary.
• Create a structured approach to the problem . Analyze what data you’ve been given and identify areas where you need more information about the client’s problem. Use a business framework to explore the case further or, better yet, create one of your own that’s specific to the issues in your case.
• Ask relevant questions and analyze the problem . Begin to share the assumptions you’re making about the case and ask the interviewing team questions about areas where you’re uncertain or need more data to inform your judgments.
• Effectively communicate your recommendation . Walk the interviewing team through your recommendation(s), explaining how you used the data provided to back up your recommendations. Make sure you call out any assumptions made or any risks associated with the action you’re proposing.

The fit or behavioral interview is a way for interviewers to figure out how well candidates would work within the firm’s culture and how they’d be in front of clients. Interviewers want to feel that they could work well with you if you were part of their team and that you’d represent the firm effectively on client projects.

While the exact questions will differ between firms, here are ten common questions asked in behavioral interviews:

PwC's Core Values

PwC has 5 core values that define its culture and approach:     

• Act with integrity
• Make a difference
• Work together
• Reimagine the possible

It’s important to ensure that when answering interview questions, you keep these values in mind. For example, if the interviewer asks you to tell them more about yourself or what you do for fun, pick stories that show where you’ve made a difference, challenged the status quo, or tried something new.

If you’re interviewing for several different firms, it’s important to tailor your responses to each individual firm. Try not to rely on stock answers about why management consulting is the role for you. Many other candidates will also be waxing lyrical about working with the best people, on the most interesting projects, for the most exciting clients.

Try researching cases the firm has recently been involved in and explain why they’re interesting to you. Or look into work the firm does regarding corporate social responsibility and talk about how it aligns with your values.

The Best Answers to PwC Behavioral Interview Questions Are Stories

Frame your examples as stories. Stories engage interviewers even after a long day interviewing dozens of candidates. While you want to remain professional, it’s ok to talk with emotion as you share your stories. Interviewers want to see humans, not robots! One of PwC’s core values is ‘Care’ so interviewers want to know what’s important to you and more about the things that make you you.

Make sure you also reflect on your own learning from the examples you want to share in your interview. You’ll likely be asked about how you work in a team, how you handle conflict, and how you overcome failure. Using a model like the ASTAR(E) framework helps you remember to share the effect that going through that experience had on you and how it’s changed how you would approach things in the future.

For the Strategy& interview specifically, it’s worth noting that you may face more behavioral questions than you expect. PwC is keen to check that you’re not just using Strategy& as an MBB backup and wants to make sure you’re a great fit for the firm.

To learn more about acing the behavioral interview, read The Consulting Fit Interview: What to Say, What NOT to Say .

PwC has traditionally used a group case as part of its recruiting process during the assessment day for some applicants (most frequently, undergraduate sophomores applying for internships). A typical group case experience involves you working within a small group to solve a business case.

Interviewers assess both analytical and behavioral competencies as you work in your team to solve the case. This means you have 2 roles during a group case. First, you need to contribute to solving the case — providing analysis, making logical assumptions and judgments, and offering insight to shape the overall recommendation you present to the client.

Secondly, you need to showcase how well you can work within a team — offering an opinion, demonstrating active listening, summarizing and building on others’ points of view, and leading the team towards consensus.

Recent interviewees have not had a group case as part of their PwC interview process. This is likely due to Covid restrictions, so make sure you are ready for a group case in the event PwC reintroduces them. If you want more help on preparing for a group case interview, read This Is What You Need to Know to Pass Your Group Case Interview .

As part of the recruitment process, you may be asked to prepare an individual presentation. This comes in the form of a written case presentation. Unlike other firms, PwC releases the information you’ll need to prepare your recommendation 48 hours in advance of the interview.

Using the information provided, you’ll have to prepare a PowerPoint presentation showing your analysis of the data, explaining any assumptions you’ve made, and detailing your client recommendations.

On the day of the interview, you’ll spend 15–30 minutes presenting your findings and then 15–30 minutes taking questions on them from the interviewing team.

Bain and BCG commonly request a written case, so this may feel familiar if you’ve interviewed for them. For more information on preparing for a written case interview, check out Written Case Interviews – Everything You Need To Know .

5 Tips for Preparing for PwC and Strategy& Interviews

Now you’re clear on the different elements that make up the PwC interviews, here are our top 5 tips for acing them:

1. Research

Make sure you do your research before your PwC or Strategy& interview. Understand what it is about the firm that appeals to you, what type of case work they’re involved in, and how else they get involved in the community.

It can sometimes be helpful to figure out what a company isn’t as much as what it is. So compare PwC to other firms and note the differences and why PwC still appeals. Learn their core values and what a typical day would involve as an analyst, or the specific role you’re applying for.

Ensure you also know as much as possible about the format for the interview. Are you expected to complete several tasks or just one? How much time will you have? Will you have a single interviewer or multiple? Company websites often describe the people they’re looking for to join their team — those will be the attributes you’ll be assessed against, so make sure you’re clear on what they are.

2. Prepare and Practice

Once you’ve done all your research, start your preparation. Use case interview examples to practice your casing skills. The linked page includes several PwC case examples as well as ones from other consulting firms. Make sure you feel confident in your case interview math skills too.

For your behavioral interview, make sure you’ve prepared answers to typical questions such as “Tell me about yourself” and “How would you manage a challenging team member?” Make sure your answers follow the ASTAR(E) framework and that you’ve tailored them to show off how you meet the PwC core values. You can practice answering these questions with a friend or coach until you feel confident in your responses.

3. Follow a Structure

Consulting firms are looking for structured thinkers who can solve a wide variety of business problems. Show your structured problem-solving skills by creating a framework that identifies the key issues you want to address in the case and use this framework to keep your progress in the case on track. Building your answers around a framework can help ensure you cover all the important points succinctly and confidently.

4. Explain Your Approach and Any Assumptions

Remember your math teacher always used to tell you to show your work? Well, it’s the same during consulting interviews. If you’re using data or solving math problems during your PwC case interview and you end up with an incorrect answer, it’s important to gain as much credit as possible.

Maybe you just made a small error in your calculation but your assumptions and approach were sound. The interviewer will never know that unless you walk them through the steps you take as you’re solving the case. Make sure you talk aloud as you’re putting together the pieces of the case and ensure you clearly state any assumptions you’ve made as you present your final recommendation. By making your assumptions clear, you‘ll allow your interviewer to guide you if you get off-track.

5. Communicate Confidently

In the PwC case interview, once you’ve decided on a recommendation, make sure you communicate your thoughts confidently. While interviewers are obviously interested in your analytical skills, business acumen, and logical approach, they also care about how you’re going to appear in front of clients. They need you to be able to effectively communicate your thoughts and respond appropriately to questions and feedback.

This is also true of the behavioral interview, where your interviewers also care about how you’ll fit within their team and what it’d be like to work long hours on a project with you. They’ll expect you to talk with passion about things you care about, offer thoughtful or interesting stories in response to questions, and seem friendly, competent, and approachable.

Preparing for Your Centerview Partners Interview: Key Questions and How to Tackle Them

Every investment bank will try to tell you that theyre unique. Theyll say that they run lean deal teams, swing for large mandates, and really emphasize culture and fit. Most of the time – as you no doubt already know – this isnt really true.

Sure, Evercore is known for having a less intense culture than Moelis. But the truth is that the differences are usually pretty small and depend on a lot of things, like which MDs you work with most of the time. So some analysts and associates will have a better experience at Moelis than Evercore and vice versa.

Among the investment banks, Centerview Partners is probably the singular one that really is quite differentiated. At the end of the day, banking is banking, but Centerview has its own way of doing things.

The truth is that not everyone can join Centerview, especially at the analyst level, as we talked about in the first question. But if youre interested in restructuring, dont shy away from Centerview.

Compared to HL, Centerview doesn’t do a lot of RX deals, but they do have a knack for getting some of the biggest and toughest ones. If you end up joining Centerview, and want to get RX exposure, youll get more than enough. There will also be interviews if you want to work for a top distressed or special situations shop.

Note: While Centerview used to offer a generalist program across M&A and RX, theyve recently changed this. Now Centerview brings on a few “Restructuring Majors” each summer to work within the dedicated RX group. While they’ll be busy with RX deals, they will still get some M deals in. These few people are the only ones who really know a lot about both RX and M.

Below are some of the top Centerview Partners questions you should prepare for. The format of the interview is the same as any other banking interview, but sometimes you will be asked more general questions, like question six.

When I write up the most common interview questions for other high-end boutiques, I don’t usually include the “Why this bank?” question. This is because the answer is usually just a general one like “they have a lot of flow” or “they seem to have a great culture.”

When it comes to Centerview, though, you should really think about why you want to work there and be ready with a good answer.

Of course you already know this, but Centerview has a three-year analyst program, and they expect you to stay for the whole thing. Also, there are great ways to leave after the analyst program, but most people stay and become associates, which is very uncommon at top EBs. It doesnt hurt when they offer you $200,000 to stick around, I suppose.

If you’re in an interview, you should never say that you don’t want to be a career banker. But no one at Moelis or PJT thinks you’re going to stay after your time as an analyst. But thats just not the case at Centerview. They want people who are leaning towards being career bankers and want to grow up within the bank.

In the first part of your answer, you should make it clear that you know the analyst program is a little different from other banks’ programs, but that you see that as a good thing because you want to stay on as an associate and beyond.

Note: You won’t have to follow up on the answer you give in an interview (especially if it’s for a summer analyst job!) But if youre looking to exit to the buy-side in 12-16 months, then you really should look elsewhere.

After this, you can give any additional generic reasons you have (e. g. , great culture, lean deal teams, large mandates, etc. ). All of those other reasons are good, but you should focus on the first two because they are the most important ones.

Landing an interview at Centerview Partners is a major accomplishment As one of the most prestigious investment banks, known for its work on complex, high-stakes deals, the competition for spots is fierce

So if you’ve got an interview lined up, congratulations! But the hard work doesn’t stop there. With Centerview’s notoriously rigorous recruiting process, you’ll need to arrive fully prepared to showcase your skills.

In this comprehensive guide, I’ll walk you through the key questions to expect and proven strategies to master them With the right preparation, you’ll be ready to ace your Centerview interview

Overview of Centerview’s Interview Process

The interview process at Centerview typically involves:

Initial Screening: Behavioral and technical questions to assess basic qualifications.

Second Round More in-depth technical and fit questions

Superday: A full day of 4-6 back-to-back interviews, testing technical, strategic thinking, and communication skills under pressure.

Throughout, you can expect a mix of technical, behavioral, brainteaser, and case-style questions. Interviews range from informal chats to highly technical quantitative sessions. The overall experience is challenging, so thorough preparation is key.

The Most Common Centerview Interview Questions

Let’s dive into the specific questions you’re likely to encounter and proven strategies to master them:

1. Walk me through a detailed DCF analysis.

This is one of the most common technical questions, assessing your financial modeling skills and valuation capabilities.

Structure your answer in a logical step-by-step manner:

Explain how you’d calculate unlevered free cash flows, starting with revenue projections based on historical performance, market data, and management guidance.

Discuss your approach to estimating expenses, taxes, capex, and working capital needs to arrive at projected EBITDA and unlevered free cash flows.

Outline how you’d determine the appropriate discount rate using WACC based on cost of debt, cost of equity, and optimal capital structure.

Walk through discounting projected free cash flows and calculating terminal value to determine enterprise value. Discuss sensible exit multiple assumptions.

Describe how you’d check your valuation output using relative valuation methods like comparable companies or precedent transactions.

Demonstrate your versatility: Highlight your experience building DCF models across diverse industries and situations like M&A, restructuring, capital raising, etc.

2. How would you go about analyzing whether a company is undervalued or overvalued?

This aims to assess your financial analysis skills and strategic thinking.

First, emphasize using a variety of quantitative and qualitative methods to develop an informed perspective on valuation, rather than relying on any single metric.

Discuss analyzing valuation multiples of comparable companies and precedent transactions to benchmark the company’s current trading levels. Compare on metrics like P/E, EV/EBITDA, P/B across several years to identify trends.

Explain reviewing DCF analysis to assess upside/downside based on projected performance. Outline assessing key value drivers and risks in projections.

Highlight importance of understanding reasons behind valuation disconnects. Analyze factors like market sentiment, competitive dynamics, new product launches, systemic macroeconomic trends that could impact the company’s performance versus market expectations.

Conclude by describing how you’d synthesize insights from quantitative and qualitative analyses into a recommendation on whether the company is significantly under/overvalued. Discuss how this would inform your investment recommendation.

3. How do you go about building 3-statement projection models?

This tests your grasp of accounting and modeling best practices.

Walk through starting with historical financial statements and normalizing for any one-time items to establish a baseline.

Discuss building integrated projections for key value drivers – revenue, margins, expenses, taxes, capex, depreciation, working capital – based on historical performance, management guidance, and competitive dynamics.

Describe linking 3-statement projections, ensuring balance sheet accounts flow from the income statement and cash flow statement.

Highlight incorporating sensitivities and scenario analysis based on risks and upside drivers.

Emphasize basics like maintaining clean formatting, labeling assumptions, cell linking, and checks for errors. Conclude by discussing how you’d analyze model outputs to derive insights and recommendations.

4. How would you value a distressed company?

This aims to assess your restructuring valuation skills.

Explain starting with Liquidation Value Analysis to determine recovery values for each stakeholder class under a liquidation scenario.

Discuss Comparable Transactions Analysis to assess value multiples of similar distressed asset sales as reference points.

Describe using a Discounted Cash Flow approach adjusted for distress – factoring in impacts of business decline on projections before assessing enterprise value.

Outline appropriate valuation considerations like limited buyer universe, discounted multiples, higher discount rates, and realistic exit scenarios.

Emphasize the importance of valuations supporting an actionable and achievable restructuring plan that creditors can endorse. Discuss assessing viability of the business continuing as a going concern.

Conclude by describing how you’d synthesize analysis into valuation ranges, recovery estimates for each stakeholder class, and strategic restructuring recommendations.

5. How would you approach a case study or business situation presented in an interview?

This assesses your problem-solving process under time pressure.

First, seek clarifying information from the interviewer if the scenario is ambiguous – you can’t demonstrate your skills if you make inaccurate assumptions.

Methodically structure your approach into distinct stages – initial hypothesis, data gathering and analysis, developing recommendations.

For data analysis, outline using frameworks like SWOT analysis or Porter’s 5 Forces to synthesize information into strategic insights.

Maintain an interactive dialogue – think aloud and welcome feedback or nudges from the interviewer.

Drive towards well-supported, actionable recommendations , weighing pros and cons of alternatives. Quantify impacts where possible.

If you get stuck, acknowledge challenges but demonstrate perseverance and creative problem-solving to work through them.

Ask clarifying questions before wrapping up to validate your logic . Concisely summarize key takeaways and next steps.

6. Pitch me a stock as if I were a client.

This tests communication skills and investing acumen.

Introduce the investment thesis upfront in a compelling, easy-to-grasp manner focused on upside potential, not just facts.

Provide historical context on business performance and trading levels to baseline the current opportunity. Use visual aids if possible.

Analyze fundamentals driving growth, risks, and market sentiment. Tie to financial performance using metrics like revenue, earnings, valuation multiples.

Support recommendations with credible data – market projections, management guidance, competitive intelligence. Provide perspectives from reputable analysts.

Acknowledge risks and counterarguments – address why they are surmountable or not dealbreakers.

Quantify expected returns under target scenarios. Demonstrate conviction on achievability.

Customize the level of complexity appropriately for the hypothetical audience. Offer to elaborate on details when asked.

Invite questions throughout to validate understanding and have an engaging discussion.

7. Walk me through your resume.

This assesses communication skills, interests, and career motivations.

Organize chronologically but focus on highlights relevant to the role, not comprehensive details.

Provide brief overviews of key experiences, companies, and responsibilities.

Emphasize transferable skills gained from past experiences and how they equip you for the role.

Align to Centerview’s strengths – e.g. if you highlight involvement in complex analysis, relate it to Centerview’s reputation for high-profile mandates.

Share interests and activities to come across as well-rounded. Relate them to strengths like teamwork, leadership, determination.

Conclude by explaining why you’re motivated for the role and planning to stay long-term. Demonstrate enthusiasm.

General Tips for Acing Your Centerview Interview

Beyond preparing for specific questions, here are some key strategies to shine:

Thoroughly research Centerview – their core strengths, specialties, culture, deal teams, past transactions, and thought leadership.

Practice aloud extensively – verbalize your thinking process to tackle nerves and reduce ums/ahs.

Strengthen financial/accounting fundamentals – ensure concepts like DCF, LBO models, 3-statement modeling are second nature.

Prepare an inventory of stories – experiences, deals, projects that exemplify desired skills. Study your resume and craft concise stories.

Review current affairs and markets – inject relevant facts and perspectives to demonstrate commercial awareness.

Plan illustrative visuals – charts, graphs, analysis summaries that vividly convey key points.

Prioritize interactive dialogue – welcome feedback an

Let’s say you want to buy 10% of a company for $50m. The company has $300m in debt, $100m in cash, $50m in capital leases, and $25m in operating leases. What’s the enterprise value of the company?

This is a relatively straight forward EV question, but with a bit of a trick thrown in.

First, we can find the equity value by taking $50m / 0. 1, which gives us $500m. Then we can add back the debt and subtract the cash to get $700m. After this, we just need to deal with our capital leases and operating leases.

Capital leases were used in the EV calculation because they were similar to debt, while operating leases were thought of as off-balance sheet items. You may have read about this difference in older IB guides. Therefore, we would just say that our final EV is $750m after including the capital leases.

However, with the introduction of IFRS 16 almost all operating leases are now considered debt-like for accounting purposes. This would mean the EV in our example here would be $775m after rolling in the operating leases (instead of just ignoring them for EV calculation purposes as you would before).

Practically, in most situations folks like to calculate EV as it was done previously (without operating leases). However, if youre just drawing an enterprise value figure out of somewhere like CapIQ theyll bundle operating leases into the EV calculation now (so you need to back out operating leases, which is annoying).

If you’re including operating leases in your enterprise value calculation, what does that do to your EV / EBITDA multiple?

As mentioned, in practice youll likely strip your EV of operating leases. But if you include operating leases in your EV calculation, your EBITDA will not be comparable, and your multiple will be too high because the numerator will be bigger than the denominator.

If you want to keep operating leases in the numerator, you’ll need to change EBITDA to include lease costs, which will give you EBITDAR.

Note: If you can’t find the operating leases anywhere on the balance sheet, you can multiply the annual lease cost by Moody’s industry multiple grid. However, if operating leases arent to be found on the balance sheet its probably because theyre incredibly small.

This is all a bit in the weeds for interview purposes. But EV calculations come up in every interview in some way, so it’s helpful to know how to do them.

Ukraine war latest: Ukraine sacks commander amid fierce battles with Russian forces; Putin reshuffle 'may hint he is preparing for future confrontation with NATO'

Fierce fighting is taking place in Ukraine's Kharkiv region, with Moscow claiming to have seized nine border villages in the area. And in Moscow, Vladimir Putin has replaced a long-time ally. Submit your question on the war for our experts below.

The Ukrainian military says Russia has had a "partial success" near a village in northern Kharkiv.

But Ukrainian soldiers stopped Russian forces from moving further near Lukyantsi, the general staff said.

It said Russian troops have continued offensive actions, and Ukraine will build up its forces in the area depending on the situation.

Russia launched an incursion from the Belgorod region in Russia across the border into northern Kharkiv on Friday.

Analysts have warned it could stretch Ukrainian forces between two fronts, creating opportunities on the main frontline that Russia may exploit.

Echoing the analysis we featured earlier from the Insitute for the Study of War (see our 11.18am post), a senior Ukrainian official has said Vladimir Putin's reshuffle shows he wants to scale up the war effort.

Ukrainian presidential adviser Mykhailo Podolyak said: "Russia is finally isolating itself and will try to scale up the war, expand its formats while reconfiguring the economy."

In a surprise move, Vladimir Putin sacked his defence minister of 12 years Sergei Shoigu and named economist Adrei Belousov as Mr Shoigu's successor.

The Institute for the Study of War said Mr Belousov, who has no military experience, will be charged with integrating the defence industrial base into wider domestic policy, further placing Russia on a war footing.

It suggests the Kremlin is preparing for a protracted conflict with Ukraine - or even possibly a future confrontation with NATO, the ISW said.

Approximately 40 miles from the fighting in northeastern Kharkiv, children in the region's namesake city are undertaking their first lessons at an underground school.

The classrooms - the first of their kind - are heavily fortified in an effort to allow some pupils to return to in-person teaching out of reach of Russia's bombs.

Kharkiv's schools have been forced to teach online throughout the war as some Russian missiles can reach the city in under a minute.

Metro stations are playing host to dozens of classrooms, while others have been welded together from layers of steel reinforcing wire and poured cement.

Russia has been increasingly carrying out off-road motorbike attacks under the cover darkness, according to British intelligence.

Lighter, faster, all-terrain vehicles have highly likely been used since the start of this year to hit Ukrainian positions, transport personnel to the frontlines and conduct reconnaissance, the UK defence ministry has said.

It said Russia reportedly purchased 2,100 Chinese off-road vehicles named Desertcross 1000-3, some of which were personally inspected by Vladimir Putin in November.

"Since the start of 2024, Russia has highly likely increased its use of light vehicles, such as all-terrain vehicles and off-road motorbikes, to transport personnel to the frontlines and conduct attacks on Ukrainian positions, particularly at night."

But the army has sacrificed armour and firepower for mobility, with light vehicles "far more vulnerable than their armoured counterparts", the UK MoD said.

Ukrainian drones have "already demonstrated their ability to effectively target" the vehicles, it added.

As we covered in some detail here earlier this year, Sweden dropped more than two centuries of historic neutrality by joining NATO.

The Baltic Sea, which includes maritime access to the Russian city of St Petersburg and the Kaliningrad enclave, is now almost surrounded by members of the alliance.

Today, Swedish prime minister Ulf Kristersson said Nordic and Baltic cooperation was "deeper than at any time in modern times", underpinned by increasing security threats from Russia.

He is hosting German chancellor Olaf Scholtz and the prime ministers of Denmark, Norway, Finland and Iceland in Stockholm, with security policy and NATO's July summit in Washington topping the agenda.

"We have long appreciated our neighbours, but at the same time underestimated the importance of concrete, operational cooperation," Mr Kristersson wrote in an op-ed in Swedish business paper Dagens Industri.

Meanwhile, the three Baltic prime ministers have been meeting in Lithuania to reaffirm that Moscow's intimidation is not going to dissuade them from supporting Ukraine.

Estonia's prime minister Kaja Kallas said that "Russia has also intensified the shadow war against all of European countries. It wants to really scare and intimidate the free world to scare us away from helping Ukraine".

"We shouldn't be scared," she added.

With a second front opening in the war and a surprise reshuffle in Vladimir Putin's cabinet, it's been an important week for the war in Ukraine.

Readers have been sending in their questions to our senior correspondents and military experts for their take on the changing battlefield environment.

Today, Jeanie asked:

Is Russia taking advantage and conducting an offensive in the border region due to the fact that several Western countries don't allow their weapons to be used on Russian soil?

Military analyst Sean Bell had this to say...

Thanks, Jeanie, for this very topical question.

Russia claims to have seized nine border settlements as part of a major offensive in the Kharkiv region. Although Ukraine has known for months that Russia was amassing military forces in the region - between 30,000 to 50 000 troops - the scale and ferocity of the attack appears to have caught Ukraine by surprise.

Although only Vladimir Putin and his senior military leadership will know the details of Russia's military strategy, most military analysts believe that Russia does not have the military resources to mount a significant and enduring second front without compromising the offensive in the Donbas - widely believed to be Russia's main effort.

However, Putin is well aware that Russia has a window of opportunity to capitalise on Ukraine's shortage of weapons, and by opening a second front, it forces Ukraine to spread its resources even more thinly, leaving Ukraine more vulnerable on the frontline in the Donbas.

Russia's military objectives for this new offensive appear to be to create a "buffer zone" to protect the Russian border town of Belgorod. This logistics hub for the Russian military effort is just within artillery range of Ukraine, and Putin has long promised to push the Ukrainian forces outside artillery range - around 30km. 

In addition, Russia wants to threaten Kharkiv, so it's pushing forward to enable its own artillery to be within range of this major Ukrainian city.

Moving large quantities of military personnel and equipment from the frontline cannot easily be done discreetly - which under normal circumstances would leave Russian forces vulnerable to Ukrainian attack. 

However, in an effort to limit the potential for escalation, the West has precluded the use of Western-provided weapons to target Russian forces on Russian territory. This significantly limits Ukraine's ability to target Russia's forces as they prepare for a fresh offensive.

However, although we can speculate on Putin's objectives, a battlefield is a dynamic environment, and Russia has considerable forces in reserve to capitalise on any momentum achieved during its current offensive.

Vladimir Putin's surprise choice of new defence minister Andrei Belousov has been speaking to a parliamentary committee as part of his confirmation process.

In his first public comments since being appointed to the post, he called for greater care for soldiers, including better access to housing, hospitals and welfare benefits. 

State media quoted him as saying there was too much bureaucracy surrounding the payment of benefits to military personnel. 

"I think it's a mess when participants in the special military operation who come back on holiday are driven from civilian medical institutions to hospitals which are often simply overcrowded. This issue needs to be resolved," Mr Belousov said.

The comments appeared to be aimed at demonstrating to members of the armed forces that he understands their concerns and will work to improve their conditions. 

In recent days, some German politicians have been calling for a no-fly zone over Ukraine enforced by NATO.

A German government spokesperson has rejected the notion, saying its stance has not changed since the alliance last denied the request.

"We rejected that at the time and I think the same applies to the different requests that are now being made," the spokesperson said.

NATO rejected a Ukrainian request for the no-fly zone in March 2022, days after Russia's invasion began.

At the time, secretary general Jens Stoltenberg justified the decision on the basis that "we are not part of this conflict".

"We have a responsibility as NATO allies to prevent this war from escalating beyond Ukraine," he said.

Vladimir Putin's cabinet reshuffle could indicate he is preparing for any future confrontation with NATO, according to a US thinktank.

The replacement of defence minister Sergei Shoigu strongly suggests he is preparing the economy and military-industrial complex for a protracted war with Ukraine, the Institute for the Study of War says.

The ISW's analysis is based on the appointment of Adrei Belousov to the post - an economist with no military experience.

He has a reputation for being an effective technocrat who has been charged with integrating Russia's defence industrial base into wider domestic policy, the ISW says.

"These high-level reshuffles following the Russian presidential election strongly suggest that Putin is taking significant steps towards mobilising the Russian economy and defence industrial base to support a protracted war in Ukraine and possibly prepare for a future confrontation with NATO."

Mr Belousov has been focused on technological innovation and drone output, which is "likely to be extremely valuable to the Kremlin".

"The Kremlin has recently had to reckon with a gap between Russian drone production and contemporary battlefield realities," the ISW says.

Ukraine has sacked the commander responsible for Kharkiv, military command has said.

Nazar Voloshyn told RBC-Ukraine media a decision was made on Saturday to appoint Brigadier General Mykhailo Drapatyi to the position.

The day before, Russia launched an incursion across Ukraine's northeastern border into the Kharkiv region.

One soldier blamed poor fortifications at the border, telling Sky News the Russian army walked "freely" across it.

Fighting continues in villages nearby, with the region's governor warning earlier this morning that it could spread to new areas.
