On Case Study Preparation , we described what a case interview question is and how you should approach answering one. You can think about that page as your Consulting Case Interview 101 course.

But if we could tell you how to ace your consulting case interview in just one page, Bain, BCG, McKinsey, and other top consulting firms would give out a lot more offers than they do every year.

On this page, we discuss the most common types of case study interview questions . We’ll take your understanding of how to answer these to the next level by outlining the key issues to consider when structuring your answer.

Let’s get started!

Here are the types of cases you might come across during your case interview :

  • Profitability Cases 1.1 Profit Optimization 1.2 Revenue Growth 1.3 Pricing Optimization 1.4 Market Entry 1.5 M&A 1.6 Cost Optimization 1.7 Startup / Early-Stage Venture
  • Non-Profitability Cases 2.1   Lives Affected 2.2 Retention 2.3 Industry Landscape and Competitive Dynamics
  • Market Sizing Questions (also called dinner conversation cases)
  • Case Interview Math (also known as consulting math) 4.1 Consulting Math Example 4.2 Summary of Key Things to Remember on Consulting Math Questions

Profitability Cases

On this page , we discussed case interview  frameworks   that can help you structure your answers to case study interview questions, we introduced the profitability equation. It’s 1 of 2 basic business frameworks you can use to answer any type of case question. 

This formula can help ensure you address all the key aspects of straightforward profitability cases like the following:

A sports apparel retailer has experienced declining sales in its stores over the past year and declining profits. How would you recommend they address their profitability problem?

A cell phone manufacturer is experiencing declining profitability despite strong sales. What should they do to improve their bottom line?

For more detail on the components in this formula and an example of how to use it to solve a case interview question, see our  Case Interview Frameworks  page . Below, we’ll discuss types of profitability problems that go beyond the basics.

Profit Optimization

Perhaps a company is profitable… just not profitable enough . 

Maybe its margins are lower than those of an industry rival. 

Maybe they’ve dipped below its own prior-year performance. 

Perhaps management sees an opportunity to launch a new product, leapfrogging the competition, but needs to generate more cash to invest in development. 

Any of these can be reasons to improve the performance of an already profitable company. 

Sample questions:

A nationwide fast-food chain failed to meet Wall Street expectations on its latest investor call and as a result, its stock price fell significantly. Management wants help identifying opportunities to improve the bottom line.

The CEO of a regional hospital chain is concerned that his company’s profitability is half that of the market leader. How can the company grow its net income?

Use the Profitability Equation

In structuring your analysis of a profit optimization case, you should touch on all 4 components of the profitability equation to understand what the company is doing well and where things have taken a turn for the worse. 

But the underlying problem in this type of case may be more subtle than in a basic profitability question. 

Instead of a big jump in costs or the loss of a large customer wiping out a significant chunk of revenue, the company may be experiencing a couple of small problems that add up to bad news for the bottom line. 

Benchmark Relative to Competition of Past Performance

For example, if our client is a TV manufacturer and we find out that our cost of producing a TV has increased overtime while our prices have remained the same, we can see that rising costs is the reason for our profits declining. 

To turn around the situation, we could look into what the competition is doing to reduce costs. For example, if a competitor is sourcing the same materials as us but from a cheaper supplier, we want to see if we can lower our cost by sourcing from the same supplier.

Benchmark One Business Segment to Another

Another way consultants benchmark performance on revenue and cost levers is by comparing the performance in one business segment or type of end-customer to another . 

Continuing with our TV manufacturing example, we might find that the client has seen costs rise on components in its high-end models but remain constant for its low-end models. 

We can look into what is being done differently in the low-end product group: low-cost sourcing, process improvement, etc. to find opportunities to improve the cost position in the high-end segment.

Use Key Performance Indicators (KPIs)

The company may also need more disciplined business processes and a system for measuring key performance indicators . 

Our TV manufacturer might institute a system for measuring cost per unit on a weekly or monthly basis in order to ensure they have an early warning system to monitor if costs are getting out of line.

To go with these KPIs, a regular process for reviewing the costs and taking necessary action could be instituted. Disciplined processes and performance indicators will help to fine-tune operations over time, taking them from good to best-in-class.

Key concepts to consider when addressing a profit optimization case:

The profitability equation including all its components,

  • Benchmarks of cost and/or revenue relative to best-in-class competition and prior year performance.  
  • Benchmark the company’s performance segmented by product or type of customer .
  • Opportunities for business process improvement and key performance indicators that will allow management to monitor profitability more closely. 

Revenue Growth

Revenue growth case questions focus on companies that, while already profitable, still want to grow. 

They can do this by increasing market share, by selling their existing products to new markets, by selling new products to their existing customers, or by pursuing a combination of these opportunities. 

They can also capture more revenue by increasing prices.

A national chain of fitness centers wants to leverage its brand equity by selling additional products and services to its client base. What incremental products and services can profitably grow revenue?

The president of a printer and ink manufacturer thinks there is an opportunity to provide after-sale service to its customer base. What might be the impact on revenue from entering this market?

Capture Additional Market Share

As its name suggests, this type of case study focuses on the first half of the profitability equation — revenue = price x quantity of units sold. in examining units sold, you should consider the company’s ability to capture additional market share for existing products in the markets it already serves. , what is the company’s current share of the market that of its largest competitor what would it take to capture additional share product improvements a shift in marketing and promotion.

If a chain of fitness centers was our client, for example, we’d look at whether the primary competition was 1 or 2 large chains or a number of small, single-location gyms and tailor our strategy to increase market share accordingly. 

If the competition was single-location gyms, we could promote flexibility for members to use our facilities in multiple locations to bring in new customers. We could also leverage the client’s greater size to outspend the small gyms on advertising.

Branch into New Products or Markets

Also, consider the new products and/or markets the company could branch into . What products do competitors sell that the company doesn’t? Does the company have capabilities that would help them  succeed in other markets?

Our fitness center client could consider selling new products like fitness apparel or vitamins. They could expand into new markets, such as towns and cities adjacent to ones currently served.

Offer Services to Existing Customers

In addition, consider  services that can be sold to existing customers . Post-sales support for equipment, for example. Or consumables used with their products, like ink for a printer manufacturer. Our fitness center client could look into providing personal fitness coaching services to members.

Review Pricing

Lastly, consider the company’s  flexibility to raise prices . Where do their prices stand relative to competitive products or services? Do their products or services have higher quality or value-added capabilities that would command a higher price?

For more examples of revenue growth case interviews, see our  Revenue Growth Case article. 

Pricing Optimization

A company must have a solid product or service offering to be able to take a price increase without seeing a significant loss of sales to competitors. 

If their products or services are strong, then optimizing price can be an important lever to grow revenue.

A manufacturer of kitchen knives sells a range of products, from low-end to professional, to customers at different price points. They’ve developed a new line of knives in collaboration with a celebrity chef and would like help setting the prices for these products.

The airline industry has experienced significant changes in its pricing model over the past few years, with some airlines charging separately for checked baggage, meals, and beverages. A global carrier has asked us to help optimize the pricing of the additional services it provides to customers who fly with them.

Elasticity of Demand

When prices rise, demand for a product goes down and when prices fall, demand rises. You’ll remember this from Economics 101, or perhaps just from common sense. Pricing optimization is all about how much . 

If you can raise prices with demand going down just a little, you can improve a company’s revenues by raising price. If a change in price has a big impact on demand, then raising price could be a big mistake.

The term for this is Price Elasticity of Demand . If demand for a product or service changes a lot in response to a change in price, it’s said to have price elasticity. Products with many substitutes or ones that consumers can easily do without are the most sensitive to price changes. 

For example, if McDonald’s raised the price of the Big Mac, more customers might go to Burger King, Taco Bell, or just eat lunch at home. McDonald’s hamburger sales would fall dramatically.

Substitutes

For some products, demand is relatively insensitive to changes in price. This can be the case for luxury goods, for products that have few substitutes , or for when there are large switching costs. When the cost of home heating oil rises, some customers consider switching to natural gas to heat their homes. But if doing so will require buying a new furnace to run on gas or paying for pipes from their house to the gas distribution network, they won’t make the change unless the change in price is dramatic and/or expected to persist for a number of years. 

3 Methods for Setting Prices

Competitive-based pricing — Setting prices based on the prices of other similar products in the market. This is the simplest method for setting prices. Companies who use competitive-based pricing are price takers.

Cost-based pricing —Setting prices as a function of the cost to provide a good or service plus a profit margin. Cost alone can’t be used to set pricing because if a company’s costs are out of line with its competitors, it may price itself out of the market.

Value-based pricing — Setting prices based on the value provided to customers. Luxury goods are priced well above the cost of their production because customers of these products value association with the prestigious image the product conveys. Products that provide significant value to customers in terms of saving time or providing features not found in other products can be priced higher because they are worth more to customers.

Value-based pricing the best pricing method but it can only be used for products and services that are sufficiently differentiated in the eyes of the customer that they will not change their buying behavior in response to higher prices.

Market Entry

Significant start-up costs will be incurred to develop and manufacture a new product, to launch the marketing campaign, or to build the sales force needed to find customers. 

To ensure that spending money on start-up costs are worthwhile, due diligence needs to be done to estimate the size of the market being considered and the cost of successfully entering it.

A teen fashion retailer has seen its sales boom in the North American market for the past 5 years. They’re considering expansion into international markets. They’d like help identifying which markets provide the best opportunities for their line of clothing.

A not-for-profit organization has been successful at hiring the long-term unemployed to manufacturer furniture made from pallets and other recycled items. They’ve not only designed and created beautiful pieces of indoor and outdoor furniture, but also helped to improve the lives of individuals in one city. They’d like to expand to other products and potentially to other cities and have asked for our help in assessing their options.

There are  4 parts to any market entry case : market size, market attractiveness, costs of entry and capabilities required. Let’s look at each.

Market size

Market sizing is sometimes used as a case interview question on its own. See below for more details . It’s also usually the first part of a market entry case. It addresses how large a market is in terms of annual revenue, number of units sold, or both. The underlying issue is whether there is enough opportunity in a market to make it worth the up-front cost.

To determine whether the amount of sales revenue or unit volume is “enough,” estimate the size of the market based on the information provided by your interviewer or by using factors you can reasonably estimate about the market. You can then consider profit margins and what portion of the market the company must capture to break even.

Market attractiveness

The market a company is thinking about entering may be huge, but it can still be unattractive. Key questions include: What is the profit margin for companies already in the market?  What does the competition in the market look like? Large firms with huge marketing budgets or small companies? 

Costs of entry

Will new technology, equipment, sales staff, or something else be required to succeed in the new market? If so, what will it cost? The greater the investment required to enter a market, the more difficult it will be to recoup the initial investment.

Capabilities

Does the firm being discussed have what it takes to succeed in the new market? In some markets, the key to success is marketing expertise and distribution. In others, it’s low costs and disciplined business processes. Identify the key attributes of success in the market and whether the company possesses those attributes.

To learn how you can structure and break down a case such as these, visit the  Case Interview Frameworks  page can help you think through important factors in this type of consulting case interview question.

Above, we looked at how to analyze a market entry case. 

If a market is attractive but the client does not have all the capabilities required to succeed in it, it may decide to buy the right capabilities through a merger or acquisition (M&A). 

They could also consider M&A opportunities if they need to enter the market fast rather than build capabilities over time.

The number 3 competitor in the cellular phone services market is at a disadvantage relative to its larger competitors. Providing cellular phone service has high fixed costs—for the equipment that transmits calls, the retail stores that sell phones and provide in-person customer support, and the marketing spend that is key to customer attraction and retention. The CEO is considering acquiring a smaller competitor in order to gain market share. He would like our help thinking through this decision.

The president of a national drug-store chain is considering acquiring a large, national health insurance provider. The merger would combine one company’s network of pharmacies and pharmacy management business with the health insurance operations of the other, vertically integrating the companies. He would like our help analyzing the potential benefits to customers and shareholders.

When you get this type of case, ask your interviewer why the company is considering the merger or acquisition. They may provide key information on the size and attractiveness of the market the target company is in. Assuming the target company is in a large, attractive market and has the critical capabilities required to succeed in that market, then you should consider whether it is better to build the new business internally or undertake a merger or acquisition. 

If two companies are considering a merger, they still have to persuade their shareholders that the 2 companies would be more valuable working together than on their own. The value the companies can create by working together is called  synergy .

Synergies from a merger or acquisition can be on the cost side, the revenue side, or both. Cost synergies include leveraging fixed costs across more business or cutting costs duplicated in both firms’ operations. Revenue side synergies include selling a broader range of products through the existing sales force or distribution channel. 

The synergies created by the merger or acquisition must be greater than the premium that must be paid to secure the deal in order for the transaction to make sense.

Integration

Mergers and acquisitions are large and complicated transactions. They require  integrating  the talent, systems, policies, and processes of the 2 organizations. Synergies that look good on PowerPoint slides do not always accrue in real life. In addition, key employees may quit during the disruption and uncertainty the M&A activity causes. Even if substantial synergies are identified, a company should consider whether it can successfully undertake the integration.

Regulatory Approval

Lastly, mergers of large companies in regulated markets (financial services, telecommunications) and concentrated markets (ones with only a few large competitors) can require government approval . The possibility of the government blocking the merger or acquisition should be considered in this type of case.

Cost Optimization

A top-3 home improvement retailer has seen price increases from several of its vendors, squeezing its bottom line. The company wants to know how it can cut costs to restore its margins to their previous levels.

The head of an automobile manufacturer has seen its production costs rise over the last several years. She wants your help in turning around this trend.

The most important thing to understand when addressing this type of case is what is going on with fixed costs and variable costs . The costs can be broken down and compared to competitors’ costs or costs in prior years to identify opportunities for improvement.

As a reminder, here are the definitions of fixed and variable costs:

Fixed Costs

Costs that you incur just because you are in business regardless of how many units you sell. Examples: factory rent, equipment depreciation, compensation for salaried employees, and property taxes. A way to think about fixed costs is that a cost that does not change over the short-term, even if a business experiences increases or decreases in its sales volume.

Variable Costs

Costs that only incur when you begin to produce units (if you sell nothing you have no variable costs). Examples: sales commissions, credit card transaction costs, and sales taxes. A way to think about variable costs is that a cost that does change over the short-term. More sales volume will mean more variable costs.

Startup / Early-Stage Venture

Startup and early-stage venture cases have some similarities to market entry cases. 

Ensuring that the market the company is going after is big enough and has high enough margins to be attractive is important, as is understanding their competition. 

Startups are small, nimble companies with only a handful of key employees and limited access to cash. These factors need to be taken into account.

A student from Iceland studying in the U.S. has determined there’s a big opportunity to bring Icelandic-style yogurt to this market. How would you recommend he proceed?

A software company has developed video technology that can be used to quickly and easily create short videos that can be sent to a colleague in place of typing a long email. This disruptive technology will take advantage of the cameras built into cell phones and laptops as well as consumers’ preference for watching a video rather than reading text. The company has a small number of beta customers and is looking for advice on how to ramp up their product to attract a wider audience.

When answering this type of case, focus on the key things that help these small, fast-growth ventures move with agility as they search for the product and business model that will attract customers and investors. 

The Right People

They need the right people —ones with product savvy, marketing savvy and investor savvy to make it. 

A Minimum Viable Product

They need a minimum viable product . This is an initial version of their product offering that will attract paying customers, allowing them earn money and to collect feedback that can be used to improve the product. It will also serve as a proof-of-concept to investors. 

A Business Plan

Start-up and early stage venture also need an initial business plan addressing how they will bring their product to market.

Non-Profitability Cases

Some might focus on charitable organization. Others might focus on businesses issues that don’t relate directly to profits, such as employee retention or understanding the competitive dynamics in an industry. 

An overview of how to approach non-profitability cases is found on this page .

This section focuses on key concepts to address in a few common types of non-profitability cases.

Lives Affected

Government agencies and charitable organizations don’t aim to maximize profits. Nonetheless, they do important work that affects many lives. 

They might hire a consulting company to help them improve their effectiveness, or a consulting firm might take on an important project for a charitable organization on a pro-bono basis. 

The state agency that administers the free summer lunch program for children of families under a certain income threshold wants to increase the reach of its program. How would you advise they approach this? 

Malaria is a devastating disease, affecting hundreds of millions of individuals each year. It’s transferred to humans by mosquitoes, with most of the cases occurring in South Asia and Sub-Saharan Africa. Though drugs to treat the disease exist, many in the affected regions don’t have access to or can’t afford these drugs. The disease is a strain on the economies of several nations, perpetuating the cycle of poverty. What can be done to alleviate this disease and its adverse economic effects?

Key Performance Indicators (KPIs)

A detailed example of how to approach a lives affected case is provided  here .  As discussed in that case, the key to answering this type of question is to find the key performance indicator (KPI) the organization is trying to improve. In the case of the first sample question above, this is the number of free lunches served to needy children. 

Benchmarking

Once you’ve established the KPI, the case can be answered in the same way you’d answer any case question on business improvement. You can benchmark the organization’s performance by looking at trends in the KPI over time or comparing the growth of the organization’s KPI to that of other organizations serving the same target population to assess whether the agency is doing a good job meeting their mandate or falling behind. If they are falling behind, drill down into the factors that might be causing them to do so.

Cases focused on employee retention are not directly about profits, though the loss of key skills when employees depart and the cost of training new hires require hurts the profitability of organizations with high turnover. 

A fast-food chain is experiencing an increase in the already-high rate of employee turnover typical in its industry. It’s also experiencing trouble attracting qualified new employees. What would you suggest?

The school system in a middle-class suburban town is experiencing higher-than-normal rates of teacher attrition. With a tight budget, they are unable to simply raise salaries to hold onto experienced teachers. What options does the school system have for increasing teacher retention?

Conducting retention interviews —interviews with departing employees to find out why they’re leaving the organization—is a standard practice in most organizations. Because of this, there should be data available on what employees like about their jobs, don’t like about their jobs, why they looked for new opportunities and what new job they’re taking. Ask your interviewer for this information, as well as survey data on the job satisfaction of all employees. It can be used to develop a multi-pronged approach to improving employee retention.

  • Look for opportunities to enhance aspects of the job that appeal to employees and change the negative aspects of working for the organization. For instance: What about the job is appealing? 
  • Do employees see the work of the organization positively impacting the broader community? 
  • Do employees like their colleagues, recognition they receive from management, the financial package provided? 

Industry Landscape and Competitive Dynamics

Cases focused on the landscape of an industry and its competitive dynamics are about the big-picture strategic issues that must be taken into account to compete effectively in that industry.

The traditional newspaper industry is facing heavy pressure from free online news organizations that don’t face the cost of printing a traditional newspaper and are able to leverage Internet ads as a source of revenue. The publisher of an award-winning regional paper would like your help in assessing and responding to this new threat.

The food and beverage industry faces disruption to their traditional brands as organic and small-batch products gain favor with consumers. How should companies in this industry respond to this new of competitive threat?

When analyzing this kind of case, first look for what is changing in the industry —consumer preferences, brand loyalty, barriers to entering the market, regulation, the industry’s cost structure, etc. Ensure you know what the source of change is before you begin to look for a strategy to help the client succeed in the new marketplace. 

For tips on structuring a case like these, visit the  Business Frameworks page . SWOT analysis and other frameworks include some factors to consider in this type of consulting case interview question.

Market Sizing Questions (Also Called Dinner Conversation Cases)

Market sizing cases are focused on establishing the size of a market in terms of annual revenue or the number of units sold rather than determining how to compete successfully in the market. 

Consulting firms often ask market sizing questions early in the consulting interview process or in interviews of undergraduate students who may not have a deep business background. 

They can also be one component of complicated, multi-step cases in later-round interviews. Market sizing questions focus on making logical estimates, showing creativity, and doing basic math.  

What is the size of the market for organic toothpaste in the United States?

How many golf balls would fit inside the Empire State building?

What Are Consulting Interviewers Looking for on Market Sizing Cases?

With case interview questions of this type, you’re not expected to know the answer, but instead to show a logical way of deducing it. Committing a few key facts to memory would serve you well. For example, knowing the population of the United States (or the country you live in) would give you a good place to start as you think through the size of the market for various retail goods. Gross domestic product can help with sizing industrial markets.

Key Statistics to Know for Market Sizing Case Questions:

The Population of the United States 2019 – 329 million according to the US Census Bureau .

World population in 2015 – 7.4 billion according to the United Nations DESA / Populations Division .

2018 Gross Domestic Product of the United States – $20.5 trillion according to the Bureau of Economic Analysis of the U.S. Department of Commerce .

Statistics like these give you a good foundation to start your market size analysis. For instance, you could begin estimating the size of the U.S. market for organic toothpaste with the US population. From there, make logical assumptions:

  • How many times a day does the average American brushes their teeth?
  • How many toothpaste applications are in the average tube of toothpaste?
  • How much does the average tube of toothpaste cost?

These assumptions will allow you to calculate the size of the overall toothpaste market in terms of annual revenue. To get to the annual revenue of organic toothpaste you’ll also need to estimate:

  • What portion of toothpaste consumers prefers organic toothpaste?

You can (and should) bring paper and a pen into consulting interviews. Use these to keep track of your assumptions as you work through them and to do the basic math required to come to a conclusion.

 Our Market Sizing Questions article has a list of the 7 steps to answering this type of question.

Key Things to Remember When Answering a Market Sizing Question:

  • Ask clarifying questions. Does the interviewer want the market size in terms of dollars or units? For the United States, North America, the world?
  • Use round numbers for simplicity. For instance, using $20 trillion for U.S. GDP rather than $20.5 would be fine.
  • Creativity in your approach to approximating the market is important, but so is good sense. Don’t be so creative that your answer lacks credibility.
  • Practice case math so you can do it quickly and correctly even under the stress of an interview.
  • Give your answer a sniff-test at the end. Does it make sense? This will both show that you are careful in your analysis and give you the chance to fix an arithmetic mistake if you find you’re way off. 

Case Interview Math (also known as consulting math)

Management consulting interviewers screen candidates to ensure that they can do basic math. 

Don’t worry if you didn’t ace multivariate calculus, the math is usually basic arithmetic—addition, subtraction, multiplication, division and fractions/percentages. You may also be asked to extract data from charts and convert from one unit of measure to another.

As mentioned in the discussion of market-sizing case questions above, you can and should bring a paper and pen into the interview. It’s fine to write out your calculations.

Consulting Math Example

In each step, we’ll provide a sense of how we are making the estimate so that the interviewer knows we’re not just grabbing a number out of the air. We want our answer to be as grounded in fact as possible. 

The population of the United States: 329 million. We’ll round to 330 million for simplicity.

The number of times the average American brushes their teeth – 2 times per day. Some people brush at lunchtime too, but that’s probably offset by people who only brush once a day.

330 million people brushing 2x’s per day gives us 660 million toothpaste applications/day.

To get to an annual number of toothpaste applications, we need to multiply by 365. That’s 241 billion toothpaste applications. We’ll round to 240 billion for simplicity.

A tube of toothpaste usually lasts me about 2 months. That means we need to divide by 120 toothpaste applications per tube to come up with the number of tubes sold annually (2 months x 30 days/month x 2 applications/day). 240 billion toothpaste applications / 120 applications per tube = 2 billion tubes of toothpaste sold in the U.S. every year.

The cost of toothpaste ranges from $1 for inexpensive brands to $4 for expensive brands, but the average cost is probably about $2. This means the total revenue for toothpaste sold in the U.S. is 2 billion tubes x $2 or $4 billion.

The percent of the toothpaste market that’s organic is a little tricky to estimate. In the grocery store I shop in, there’s 1 aisle of organic goods in a store that has 20 aisles – that means organic products make up 5% of shelf space (and presumably also of sales). 

I think that people would be less likely to buy organic toothpaste than organic food, because you eat organic food, but you spit organic toothpaste out into the sink. Organic products always cost more and organic toothpaste doesn’t seem quite as important to your health. 

Conclusion: Based on that, I’ll say that 1% of the market for toothpaste is organic, so if $4 billion in toothpaste is sold in the U.S. every year, $40 million of it is organic toothpaste.

Is our answer right? 

Probably not exactly. There are different sizes of toothpaste tubes, a complication that we did not consider in this analysis. There might be some people who don’t brush their teeth every day. That would mean that we overestimated consumption. 

But our estimate of the market size for organic toothpaste is reasonable and grounded in logical assumptions. We could sniff-test our answer by comparing it to a market size we know, or to GDP, one of the facts we suggested having in your back pocket for market sizing case questions. 

U.S. GDP was about $20 trillion in 2018. Our estimations suggest that the overall toothpaste market is $4 billion. That means toothpaste is 1/5,000 of the U.S. economy, and the market for organic toothpaste is 1% of that. 

That sounds plausible. If your answer showed that the market for organic toothpaste was larger than U.S. GDP, it would be a clear indication that you made a mistake somewhere along the way.

For the 4 types of math problems you’ll be asked to compute as part of case studies, read Case Interview Math.

Above, we’ve provided you with 11 different types of case interview questions you might be asked during your consulting interviews. We’ve also told you that you need to get great at doing case math. 

Overwhelming? It can be.

But it doesn’t have to be.

The best way to prepare for your consulting case interviews is NOT to spend hundreds of hours reading every case study question and answer you can get your hands on. Instead, see our page on Case Interview Practice  to find out how to make the most of your interview prep time. In addition, check out this video where Davis Nguyen, Founder of My Consulting Offer, talks about how mastering the case interview is made easier when you focus on the most common types of cases.

How to Write a Case Study and Increase YOY Revenue by 25%

Illustration Of Case Study Guide

Voices.com saw a 25% increase in year-over-year revenue after publishing its case study.

If you want to replicate its revenue growth in your company, you’re in the right place.

This guide outlines how to write a case study in seven high-level steps, along with three very different real-world case study examples.

How to Write a Case Study in 7 High-Level Steps

A powerful story convinces prospective customers that you’re the real deal. This section outlines the seven core steps of writing an effective case study that attracts your ideal customers on autopilot.

Step 1. Gather marketers and sales in the same room

Too often, we hear stories of marketing and sales playing the blame game—and it’s a shame as alignment between these two opposing departments breaks down silos and unlocks revenue acceleration in the long run.

How To Write A Case Study: Gather Marketers And Sales In The Same Room

Consider the following statistics from LinkedIn :

  • 60% of members believed that marketing-and-sales misalignment could damage financial performance
  • LinkedIn members exposed to a company’s marketing messages on the platform are 25% more likely to respond to a message from said company’s salesperson
  • Sales folks who often share quality content are 45% more likely to exceed their sales quota

CEOs (or other C-suite roles like CROs ) should gather marketing and sales in a room and get them on the same page. Rather than creating a marketing case study on the fly, let the sales team lead you .

Use the following questions to narrow down on the type of content you should create: 

Questions #1-#3 shape the elements of your customer success story, such as the product features, angle, and headline.  

Whereas, questions #4 and #5 identify your most profitable clients (a.k.a. your case study candidate) and the common attributes to focus on to attract more of them. 

Your sales team’s response provides one side of the story. To gain a better understanding of your best customers today, use a tool like Breadcrumbs Reveal .

It analyzes your marketing, sales, and product data and tells you what attributes and actions are the best predictors of revenue. To get started:

  • Connect your data sources with Reveal
  • Define your criteria for success (e.g., enterprise plan)

Breadcrumbs Reveal will return a detailed view of your best customers today. It will also reveal your data health and the data that can be trusted. 

Alt=&Quot;How-To-Write-A-Case-Study-Breadcrumbs-Reveal&Quot;

Use the data provided to pin down the candidates for your client case studies—and update your ideal customer profile (ICP) while you’re at it.

Step 2. Pick the best candidate 

Not all customers are equal. For example, a company that recently moved upmarket will focus on enterprise clients. 

Now that you’ve identified your best customers today and the customer objections you need to overcome, it’s time to find the right candidate.

Ideally, the right candidate for your before-and-after story ticks these two boxes:

  • Belongs in your best customer segments 
  • Achieves stellar results from your product or service 

GrowSurf, a referral software company, focused on newsletter publishers.

How To Write A Case Study: Pick The Best Candidate

Co-founder Kevin Yun explains his choice with Breadcrumbs, “They were running a great referral program and getting great results. The top five referrers had around 500 referrals collectively.” 

Step 3. Request a case study interview 

Writing case studies involves more than a compelling story, persuasive writing style, and authentic, real-world images that show the collaboration in action.

For all this to happen, you need to convince the client for an interview at the right time . 

There are two options, according to David Ciccarelli, CEO and founder of Voices.com. Either you ask after delivering the work or when you’re starting to see significant results.

He explains to Breadcrumbs, “Asking before you finish the work will get you a quick ‘no.’ However, when you wait until the client has experienced success, you’re far more likely to get a ‘yes.’”

This brings us to the next question: who should ask the client for an interview?  

Our take: the salesperson, as they’ve already established rapport and have the closest contact with the client.

At Voices.com, the account manager invites the customer for an interview. If it’s a yes, the account manager makes a nomination. 

How To Write A Case Study: Request A Case Study Interview 

This process involves filling a form in the CRM , indicating the company name, point of contact, project details, and a link to the deliverables. 

Next, these nominations are handed off to the communications manager, who acts as the case study’s creator and brand steward and determines if there’s a fit. 

If there is, the Voices.com team proceeds with the case study interview .

Run a contest to gain momentum in your case study initiative . At Voices.com, the sales rep who submits the most number of nominations wins a prize. 

Not only do you get the sought-after case study, but you also encourage the sales team to participate in a friendly game, boosting employee engagement by tenfold.

Step 4. Overcome concerns and objections

Sales reps who overcome objections enjoy a close rate as high as 64% —all the more reason you shouldn’t let the initial objections stop you from closing. 

Yes, this applies to case studies. 

There are various ways to bypass these initial nos.

If the client is sensitive about sharing results, instead of explicitly listing the exact figures in the case study, opt for a percentage format (e.g., “115% increase of revenue” rather than “…revenue increased to $593,938”).

Other ways to overcome objections include: 

(i) Anonymizing names, roles, or even the name of their companies 

(ii) Sharing process without diving into the strategy’s specifics

Describe the general approach to achieving results. Avoid the nitty-gritty that gives away your top strategies.

It’s a mouthful, but you get the idea.  

Sometimes, clients need more context before agreeing to a case study interview. Share how you plan to use and distribute it.

What you want to do here is sweeten the pot. 

Talk about how the case study improves their SEO or boosts visibility to potential customers .

Voices.com always tells its clients how it plans to share the case study via social media posts and its newsletter. Since the latter channel has hundreds of thousands of subscribers, it’s “sufficient enough to demonstrate the quality of the case study,” says David. 

“For many clients, the added brand visibility is a huge incentive.”

A word of caution, if the objection centers around legal restrictions or if the client just isn’t interested, move on to the next client.  

“Rather than jeopardizing our business relationship, we work at improving their experience,” adds David.

Step 5. Interview the client and gather intel

It’s D-Day.

Prepare a list of open-ended questions that outlines the client’s before-and-after transformation. 

“When you frame your questions,” shares Kevin Yun, co-founder of GrowSurf, “You can synthesize the story from the transcript and craft a case study that resonates with prospects.”

Here are eight questions to get you started:

These answers are not only helpful in your case study, but also your customer research and content marketing strategy .

For example, #3 unearths insights about your competitors and shapes the backbone of your content strategy . This is also valuable if you’re wondering what to write for your product comparison posts.

Pro Tip : Keep the data at the back of your mind as you start planning for the case study content. While the customer quote adds the human element and the emotional ‘oomph’, it’s the data that proves your expertise.

“Consolidating all the data allows you to leverage key takeaways and highlights when building your first-ever business case study, “ shares Gabrielle Carreiro, founder of Binge Digital , with Breadcrumbs.

“This is important because not only do you want to back up your work with quantifiable results, but you also want to draw attention to the success you’ve driven and position yourself as a thought leader in your industry.”

Step 6. Create the case study and bring it to life

By now, you should have a lot of information at your fingertips. Review the interview transcript and edit the client’s answers into the following format:

  • Overview : Introduce the client and the current state of the company, along with a compelling headline
  • Problem : Describe the ‘trigger’ that led the client to look for your solution. Agitate the pain point and share what’s not working
  • Solution : Explain what you did to solve the problem. This is the perfect chance to spotlight your process and value proposition (or better yet, your unique selling proposition) 
  • Results : Share the results you delivered in exact figures. If it’s not possible, anonymize the data

Design follows copy. 

After writing the case study content, work with the design team to explore how you can bring the elements (e.g., case study headline, background colors) to life.

Step 7. Distribute the case study and repurpose in other formats

Your new case study is finally completed. 

Now all that’s left to do is to promote it and show everyone what you have accomplished in your space.

Consider the following distribution ideas to boost visibility:

  • Upload it on a digital asset management platform (DAM) where every stakeholder can easily access the case studies
  • Promote it in all employees’ email signatures
  • Share it on social media and encourage your team to do the same
  • Cross-post on channels like LinkedIn and Medium. Don’t forget to link it back to the original source.
  • Guest post on relevant publications and non-competing blogs to add a backlink to your case study
  • Print your case study and distribute it to prospects at networking events and large conferences. This beats handing out business cards that are bound to go missing amid the chaos!
  • Pitch your case study to podcasts . Tell the podcast host about your unique process and offer your unique take to their listeners.
  • Repurpose or expand your case study into a webinar , infographic, checklist, blog post, or ebook
  • Subscribe to sourcing services like Help a Reporter (HARO) and Help a B2B Writer. Pitch your case studies when you come across a relevant opportunity

Content distribution is never a one-off task. Promote your case studies and repurpose them as needed to attract new clients .

Now That You’ve Learned How To Write A Case Study, What’s Next?

Case studies highlight your unique expertise and convince a skeptical lead. If you haven’t been dedicating time and resources to create them, you’re missing out on many revenue opportunities .

Generally, leads who read case studies sit further down the funnel and are ready for sales . If you want to pitch these leads (what salesperson doesn’t?), use a contact scoring tool like Breadcrumbs .

Here’s how it works:

  • Connect your CRM with Breadcrumbs
  • Determine your ideal customer’s attributes in the Fit model (e.g., CMO from a $10ARR company with 50 employees) 
  • Determine the actions that show a buying intent in the Activity model 

For example, if you want to target prospects who read case studies on your site, select Page Visits under Matching Event and include the URL accordingly. 

How To Write A Case Study: Breadcrumbs

Each action and attribute is assigned a score. The more actions a lead completes and the more attributes they “fit,” the higher their score will be.

Once they hit a threshold—a score predefined by you—Breadcrumbs will send all scoring information back to the CRM of your choice and alert you of the sales opportunity.

This helps you focus on sales-ready leads, gaining back hours of your time, closing more profitable deals, and crushing your quota. 

Pro tip : Connect your product analytics and email marketing platforms with Breadcrumbs to gain a holistic view of the customer’s journey .

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?

Let's dive right in and find out!

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:

Case Focus

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:

Case interview breakdown

  • 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:

Four Steps to Identify the Problem

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:

Frame the Airline Case Study

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.

Frame the Airline Case Study Hypothesis

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:

Lead the analysis for the Airline Case Study

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:

The Pyramid principle often used in consulting

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.

Getting stuck

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:

Profitability framework

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:

Conservation case

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:

Coffee segmentation

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 .

Pricing Basics

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:

Net Present Value

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.

Competitive Interaction Structure

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 :

McKinsey Diconsa Case

The first question addressed to the candidate is the following:

McKinsey Diconsa Case

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:

McKinsey Framework

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.

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!

What's the best way to structure a revenue growth case.

I'm tempted to start with p * q, but it sometimes feels unnatural to shoehorn the necessary questions (distribution channels, marketing, customer, market characteristics, competition, product, company,etc. depending on the case) under either "price" or "quantity". At the same time, it feels odd to ignore the p * q structure altogether. How should I approach this?

Overview of answers

  • Date ascending
  • Date descending

It depends very much on the industry. In some cases (Growth strategy) I will use a broad structure, in others (e.g. “how to increase the excessive luggage revenues for an Airline”) I will use P, Q and the Process. Here is the broad structure that you can adapt to your industry:

Analyze the market:

  • Size and growth rates
  • Segments (geographical, customer, product)
  • Distributors / Suppliers
  • Key market trends

Analyze the competitors:

  • Market shares, growth rates, profits
  • Product / customer / geographical mix
  • Products (Value proposition)
  • Unit economics (Value proposition vs. price vs. costs)
  • Key capabilities (Distribution, supply, assets, knowledge, etc)

Analyze our company:

  • Market share, growth rates, profit

How to increase revenues:

  • How to increase the scope: Product / customer scope, geographical scope
  • How to improve value proposition (How to fix your weaknesses and improve your strengths; Potential increase in price and volumes)
  • How to answer the competitors (Unique or hard to build property and contracts; Customers / suppliers / complements with lock-in; Reputation and relationships; Organizational capabilities; Product features and know-how)
  • Other benefits of scale (Spreading Fixed costs, Change in technology, Bragaining power)

Structure revenue growth case with multiple products

First of all, In the clarifying questions, I ask proactively how many products / revenue streams we have

  • If I have just two products or two revenue streams I would split the products on the revenue level (e.g. revenue from product 1, revenue from product 2)
  • If I have 2+ products I usually go with revenues, split them into price and quantity. Under price, I use a vertical numbered list of products . e.g. 1) x 2) y 3) z. Same with the quantity
  • In the last case, I will end up with a table under my structure since both price and qty (and maybe variable costs per unit as well) will have a numbered vertical list

Thanks a lot, this was really helpful

This is the structure I would suggest for a growth strategy case:

  • Clarify goal. How much do we want to grow, in which period of time and constraints (eg specific budget). If needed, clarify business model.
  • Analyse growth and size for segment covered by client and competitors. Compare the client to competitors performance to spot potential areas where to grow further
  • For segments that could potentially allow to meet the goal, analyse further competitors, customer segments and barriers to entry
  • Ways to increase price
  • Ways to increase volume
  • Product variety
  • Diversification
  • Select grow strategy providing the maximum result with the minimum amount of resources required, and meeting constraints identified at step 1
  • Consider risks/next steps following grow strategy. Eg increasing the price may lead to higher decrease in volume than expected – could be better then to test on specific areas.

Hope this helps,

Hi Anonymous,

I would suggest to use the first method, but with a switch; you won’t need indeed to know price and volume for all the segments . More specifically:

  • I would start dividing in revenue streams (not necessarily by product – it could also be by customer or distribution channel)
  • I would then ask how revenues changed for each stream
  • I would start from the one that had the biggest decline in revenues. For that only, I would then move to divide in price and volume to identify the issue. In case we are not able to fix the issue, I would then move to the second-worst stream

The reason I believe this method is superior to an initial division of revenues in price * volume is that will allow to understand immediately the real reason for the problem, and for which segment . With an initial division in price*volume, that may not always be the case.

Assuming for example that the problem of the company is a decline in volume of the more expensive product A by 10 units and at the same time the cheaper product B increased by 20 units, dividing in price*volume will show an increase of volume and a decrease of the average price – thus apparently a price issue. Although you may eventually identify the issue is volume for product A, and thus not price related, this would take longer than following the previous steps.

There's several different ways of approaching the same case (and they can all be right!), that said, below you can find the one I often prefer :

1. Analyze the external factors/market (I do like to know what's going on in the market before even understanding what's going on with the company; as you can imagine it's different if a company wants to grow revenues by 10% in a market growing 20% vs. a market that is even declining!)

- Evolution of market (previous and future)

- Competitive landscape

- Consumer tastes and trends

- Regulation

2. Analyze the internal factors

- revenue tree (try to avoid simply stating Price * Quantity, try to give some tailoring to the industry you're talking about; e.g., for gyms you can say the number of clients who have a monthly pass * the monthly fee.. it will positively impress your interviewer!); if company is multi-product you should take that into consideration here and open multiple revenue streams in the branches!

- sometimes I also include company capabilities as a separe point , depending on the specifics of the case and goal

Hope this can be helpful, any query on it just let me know :)

You've already received excellent responses. What I will build on is the higher level structure when approaching problem solving (i.e. after asking clarification questions and understanding the objectives).

You should start with thinking about how revenue growth is achieved: organically or inorganically (or both). Under organic growth, you can achieve that through

1. Increasing the price, as you've mentioned

2. Increasing the quantity - either by increasing your market share with existing customers or by targeting new customers

3. Launching new products/services - could be complementary produts, or entirely new ones

4. Entering new markets

Out of the box answers:

5. Increase the utilization of your existing products - the toothpaste example is great. DM me for more details.

6. Target non-customers and make them customers - increase the entire market size

You can achieve inorganic growth through:

1. An Acquisitions - of companies or products

2. A Merger

Now that you've defined the high level structure, you cover all grounds to grow revenue and will not make the mistake of forgetting any points as you go along with the case, especially when the interviewer asks you how else could you grow revenue (under each category you could expand. Ex: licensing deals, contract manufacturing, commercial agreements etc...).

After defining the high level structure, you could then figure out where to start based on the case and your clarification questions to the interviewer and begin with the points mentioned by the other experts that have responded to you (analyze market, competitors etc...).

Hope this helps.

Agreed with above. As stated by Bruno, the correct way to think about market expansion is to think about:

-demand evolution (external)

-supply evolution (external AND internal)

-effect on price (it's a market after all)

Now, two things that should never be forgotten, even if it's a revenue growth case

-how much does it cost and does it increase profits?

-what is impact to profit margins (a lot of times you don't go for market expansions that are margin dilutive, due to impact on stock price)

ask to your interviewer if there are any objectives for the two points above or any thresholds or you can ignore for the case.

hope it helps,

So my approach is as follows:

1) New business areas

1a: New Products

1b: New Customer Segments

1c: New Geographical markets

2) Existing business areas

2a: Increase price

2b: Increase volume from existing customers

2bi) Selling more frequently of the same products

2bii) Cross sell different products to existing customers

All the best!

No please do not structure it like that in MBB, 95% chance you will fail. Rather group it in buckets relevant to the case. Warm regards, Frederic

You can also discuss how you use data-driven decision making and financial modeling to evaluate potential revenue opportunities. Finally, be sure to mention any specific tools or techniques that you are familiar with and have used in your previous roles.

Example: “I have a strong background in revenue management and use several strategies to identify and analyze potential revenue opportunities. I typically start by doing market research and analysis, then move on to competitor analysis, customer segmentation, pricing optimization, and product bundling. I also rely heavily on data-driven decision making and financial modeling when evaluating potential revenue sources. Additionally, I am familiar with various tools such as Tableau, Excel, and SQL that help me visualize the data and make more informed decisions.”

2. Describe your experience with developing pricing models for products or services.

Pricing models are often a major component of a revenue manager’s job. They’re responsible for determining the most effective and profitable way to price products and services, and must use analytics and data to make their decisions. Interviewers will want to know that you have the experience necessary to make effective pricing decisions and can communicate your process effectively.

Your answer should focus on your process for identifying and analyzing revenue opportunities. Talk about the strategies you use to collect data and analyze it in order to make pricing decisions.

Finally, be sure to emphasize any successes you’ve had with pricing initiatives—this will show the interviewer that you have the experience needed to succeed in this role.

Example: “I have extensive experience in developing pricing models for products and services. I start by analyzing the current market conditions to determine what competitors are charging and how our product or service compares. From there, I use data from customer surveys and feedback to understand their needs and expectations. I also collaborate with marketing to ensure that any promotional campaigns align with our pricing strategy. Finally, I develop a model that takes into account all of these factors and present it to the team for approval. My process has been successful in driving revenue growth while still keeping prices competitive.”

3. How do you ensure that the company’s pricing strategy is competitive in the market?

Revenue managers are responsible for driving revenue and profitability for a company. This means they need to understand the market and the competition, and be able to come up with a pricing strategy that meets the company’s goals. Interviewers want to know that you can identify and analyze the relevant data and come up with a pricing strategy that is effective and competitive.

To answer this question, you should talk about the steps you would take to ensure that the company’s pricing strategy is competitive in the market. Start by discussing how you would research and analyze competitors’ pricing strategies and identify any trends or opportunities for improvement. Then explain how you would use this data to come up with a pricing strategy that meets the company’s goals while remaining competitive. Finally, discuss how you would track and adjust the pricing strategy as needed.

Example: “When creating a pricing strategy for the company, I would start by researching our competitors and analyzing their pricing strategies. I would look at factors such as market trends, customer preferences, and industry best practices to identify any potential opportunities or areas of improvement. With this data in hand, I would then create a pricing strategy that meets the company’s goals while still remaining competitive in the market. Additionally, I would track and adjust the pricing strategy on an ongoing basis based on feedback from customers and changes in the market.”

4. Explain how you would go about creating a customer segmentation model.

The ability to create customer segmentation models is a key part of a revenue manager’s job. By understanding customer behavior, the revenue manager can develop strategies to better target customers and grow revenue. This question allows the interviewer to evaluate the candidate’s knowledge of customer segmentation and their analytical skills.

Start by explaining the basics of customer segmentation and how it can be used to identify customer needs. Then, discuss the process you would use to create a customer segmentation model. This includes analyzing customer data, such as demographics, purchasing behavior, and preferences; creating segments based on this data; and validating these segments with additional research. Finally, explain how you would use the insights gained from the model to develop targeted strategies that will help grow revenue.

Example: “Creating a customer segmentation model starts with analyzing customer data, such as demographics, purchasing behavior, and preferences. This helps to identify customer needs and develop segments based on this information. Once the segments have been created, I would validate these segments with additional research, such as surveys or interviews. From there, I can use the insights gained from the model to develop targeted strategies that will help grow revenue. For example, if one of the segments is identified as being price-sensitive, then I could create special offers for that segment in order to drive more sales.”

5. Are you familiar with any revenue management software programs?

Revenue managers are expected to be comfortable with technology and software programs that help them manage data and track revenue. This question allows the interviewer to gauge your knowledge of the software used in the job and whether you have the skills to quickly learn and use them.

You should be prepared to answer this question by talking about the specific software programs you have used in the past and any experience you have with revenue management. If you don’t have any direct experience, talk about your ability to quickly learn new software programs and how you would go about doing so. You can also mention any certifications or courses that you have taken related to the software.

Example: “I have experience using major revenue management software programs such as Oracle Revenue Management and IBM Cognos. I’m also familiar with less popular programs, like RevGenius and RMXpert. I’m confident that I can quickly learn any new software program needed for this role since I am comfortable with technology and have a good understanding of how these systems work. Additionally, I recently completed a certification course on data analysis and visualization in Excel which has helped me understand the importance of accurate data tracking.”

6. What methods do you use to track and measure revenue performance?

Revenue managers are required to have a keen understanding of the numbers that drive the company’s success. Knowing what methods you use to track and measure revenue performance will give the interviewer an idea of your analytical skills and ability to understand the complexities of the job. Additionally, it will give them an understanding of how you think about budgeting, forecasting, and other important financial tasks.

In your answer, be sure to highlight any experience you have with tracking and measuring revenue performance. You should also talk about the methods you use or have used in the past, such as budgeting, forecasting, financial modeling, etc. Additionally, it’s important to explain how you interpret the data and what actionable steps you take based on your findings.

I use a variety of methods, such as budgeting, forecasting, financial modeling, and data analysis to track our revenue streams. Additionally, I review the data regularly and look for any trends or changes that could affect our revenues. Based on my findings, I provide actionable insights to help us make better decisions and maximize profitability. I’m also experienced in creating reports and presentations to present these findings to stakeholders.”

7. How do you handle forecasting future revenue trends?

Revenue managers are expected to be able to accurately predict future revenue trends and make adjustments accordingly. The interviewer wants to know that you have the necessary experience and skills to do this. They also want to know that you are able to take into account all the external factors that may affect revenue, such as market conditions, customer satisfaction, and competition.

To prepare to answer this question, you should be familiar with the forecasting process and strategies that are used in your industry. You can then explain how you use these strategies to make predictions about future revenue trends. Be sure to emphasize any experience you have with using data or analytics to inform your decisions. Finally, it’s important to show that you understand the external factors that affect revenue and how you take them into account when making forecasts.

Example: “I use a combination of market research, customer feedback, and analytics to forecast future revenue trends. I’m very familiar with the industry’s forecasting process and strategies and understand how external factors such as competition, consumer sentiment, and economic conditions can affect revenue. I also use data analysis tools like Excel or Tableau to help me track past trends and make more accurate predictions about future performance. Ultimately, my goal is always to be able to identify potential risks and opportunities for growth in order to maximize profits.”

8. What strategies do you use to maximize revenue from existing customers?

Maximizing revenue from existing customers is a key responsibility of a revenue manager. The interviewer wants to know if you have ideas and strategies for achieving this goal. They want to know if you can think strategically and come up with creative solutions to increase revenue without necessarily increasing customer acquisition costs. They also want to know if you have a good understanding of customer behavior and how to use data to drive decisions.

Finally, emphasize your ability to think strategically and come up with creative solutions to maximize revenue from existing customers.

Example: “I have a few strategies that I use to maximize revenue from existing customers. First, I use data to segment customers based on their usage, so I can target them with tailored offers and discounts that are more likely to be accepted. Second, I use analytics to track the performance of campaigns and optimize for maximum ROI. Third, I leverage customer feedback to inform product development and identify new revenue opportunities. Finally, I’m always thinking of creative solutions to increase revenue without necessarily increasing customer acquisition costs. All of these strategies have helped me to successfully maximize revenue from existing customers in my past roles.”

9. Describe your experience with managing sales teams and setting goals.

Revenue managers are responsible for leading sales teams, setting goals, and ensuring that the team meets those goals. This question gives the interviewer an insight into your ability to manage sales teams, set goals, and track performance. It also allows the interviewer to understand how you motivate and engage with sales teams to ensure that they hit the goals that you set.

Start by talking about your experience managing sales teams and setting goals. Describe any successes that you’ve had in the past, such as hitting targets or exceeding expectations. Talk about how you motivate and engage with sales teams to ensure that they hit their targets. Finally, explain how you track performance and use data to adjust goals if needed.

I use a combination of data-driven and hands-on techniques to ensure that the team is motivated and on track with their goals. I also use data to track performance, adjust goals if needed, and provide feedback to the team. I have a proven ability to successfully lead sales teams and achieve their goals.”

10. How do you approach identifying new markets and expanding into them?

I have a proven track record of implementing successful customer loyalty and retention strategies that have resulted in increased customer loyalty and revenue growth.”

12. How do you stay informed about industry trends and developments?

Revenue managers need to be up-to-date on the latest news and trends in the industry to ensure their strategies are always at the cutting edge. This means staying in the loop on the latest technology, regulations, and customer preferences, among other topics. If a potential hire can’t demonstrate that they’re well-versed in the current climate, they may not be the right fit for the job.

To answer this question, you should provide examples of how you stay informed. This could include reading industry publications and blogs, attending conferences and webinars, or simply staying in touch with your network to hear about the latest news. You can also mention any specific tools or resources that you use to keep up-to-date, such as subscription services or newsletters.

This question is a great opportunity to show off your knowledge of international regulations and customs, as well as any language skills you possess.

Talk about any international clients you’ve worked with in the past, and why you were successful in managing those relationships.

I’m also fluent in French and have a basic understanding of German, so I’m able to communicate with clients in their native language. I’m confident I could bring this same level of expertise to your team.”

15. How do you handle difficult conversations with customers regarding pricing changes?

Revenue managers are responsible for ensuring a company’s revenue goals are met, which often means having difficult conversations with customers. The interviewer will want to know that you can handle these conversations professionally and diplomatically, while still being able to explain the reasoning behind the pricing changes and why they are necessary. The interviewer will also want to know how you handle customer objections and how you can turn a difficult conversation into a positive outcome.

Example: “I was recently faced with a difficult decision when a major customer asked for a significant discount on a large order. I had to decide whether to offer the discount or risk losing the customer. After carefully considering the situation, I decided that the potential long-term benefits of keeping the customer exceeded the short-term cost of the discount. I offered a discount that was less than what the customer asked for and was able to retain the customer, resulting in a $200,000 annual increase in revenue.”

The Future of Solar Energy in the USA

Solar energy global capacity has been growing almost exponentially for the last three decades. Now this technology is facing an inflection point. According to the International Energy Agency (EIA), solar PV can become the main source of power generation, surpassing coal by 2027. In the U.S., during the second quarter this year, the solar industry installed 6.1 GW of new capacity making this the best quarter in history, in part owing to a surge in demand from the Inflation Reduction Act (IRA). But still, Wood Mackenzie expects the US solar market to triple in size over the next five years, bringing the total installed solar capacity to 378 GW by 2028. But is this technology mature enough to drive this growth? Can we rely so intensively on solar energy? In this episode of Glennmont Insights, we talk to Jon Burke about the future of the solar energy in the USA. Jon Burke is President of GreenGo US, a renewable energy developer. Jon has over 20 years’ experience in the energy sector, especially solar PV in the USA. Jon also held senior leadership positions at Apex Clean Energy, Shell, and National Renewable Energy Corporation.

The Supply Chain in US Renewables and impact of the IRA

The Biden Administration has set very ambitious targets for decarbonization in the US, a target of 100% carbon pollution free electricity by 2035 and a net zero US economy no later than 2050. The IRA is a critical driver of these goals and will enable renewables capacity to increase to over 900 GW across US markets, representing $420bn of capital expenditure. The big question is whether the supply chain will be able to support these lofty goals, given the heavy focus on US domestic content in the IRA. In this episode of Glennmont Insights, we talk to Oliver Kerr to discuss the status of the renewables supply chain in the US and the impact of the IRA. Oliver Kerr is the Head of North America of Aurora Energy Research, an energy research company, providing market leading forecasts & data-driven intelligence for the global energy transition.

Synergies between Hydrogen and Renewable Energy: two real case studies - Part 2

In the first part of this episode we explored two real case studies of H2 projects with Helena Anderson and Sandra Leece. In this second part we have an interesting debate on how they would respond to the question: are H2 projects better set large or small?

  • Yale (2013)

Consulting casebooks are documents that MBA consulting clubs put together to help their members prepare for consulting case interviews. Consulting casebooks provide some case interview strategies and tips, but they mostly contain case interview practice cases.

While consulting casebooks contain tons of practice cases, there is quite a bit of variety in the sources and formats of these cases.

Some practice cases are taken from actual consulting interviews given by consulting firms. These are the best types of cases to practice with because they closely simulate the length and difficulty of an actual case interview. Other practice cases may be written by the consulting club’s officers. These cases are less realistic, but can still offer great practice.

The formats of the practice cases in consulting casebooks also vary significantly.

Some practice cases are written in a question and answer format. This type of format makes it easy to practice the case by yourself, without a case partner. Other practices cases are written in a dialogue format. These cases are better for practicing with a case interview partner.

MBA consulting casebooks can be a great resource because they are free and provide tons of practice cases to hone your case interview skills. However, there are several caveats that you should be aware of.

  • Similarity to real case interviews : Some cases in MBA consulting casebooks are not representative of actual case interviews because they are written by consulting club officers instead of interviewers from consulting firms
  • Quality of sample answers : While consulting casebooks provide sample solutions, these answers are often not the best or highest quality answers
  • Ease of use : Consulting casebooks are all written in different formats and by different people. Therefore, it can be challenging to find cases that you can consistently use to practice cases by yourself or with a partner

Therefore, we recommend that you first use the case interview examples listed in this article and wait until you’ve exhausted all of them before using MBA consulting casebooks.

How to Use Case Interview Examples to Practice Case Interviews

To get the most out of these case interview examples and maximize your time spent on case interview practice, follow these three steps.

1. Understand the case interview structure beforehand

If case interviews are something new to you, we recommend watching the following video to learn the basics of case interviews in under 30 minutes.

Know that there are seven major steps of a case interview.

  • Understanding the case background : Take note while the interviewer gives you the case background information. Afterwards, provide a concise synthesis to confirm your understanding of the situation and objective
  • Asking clarifying questions : Ask questions to better understand the case background and objective
  • Structuring a framework : Lay out a framework of what areas you want to look into in order to answer or solve the case
  • Kicking off the case : Propose an area of your framework that you would like to dive deeper into 
  • Solving quantitative problems : Solve a variety of different quantitative problems, such as market sizing questions and profitability questions. You may also be given charts and graphs to analyze or interpret
  • Answering qualitative questions : You may be asked to brainstorm ideas or be asked to give your business opinion on a particular issue or topic
  • Delivering a recommendation : Summarize the key takeaways from the case to deliver a firm and concise recommendation

2. Learn how to practice case interviews by yourself 

There are 6 steps to practice case interviews by yourself. The goal of these steps is to simulate a real case interview as closely as you can so that you practice the same skills and techniques that you are going to use in a real case interview.

  • Synthesize the case background information out loud : Start the practice case interview by reading the case background information. Then, just as you would do in a live case interview, summarize the case background information out loud
  • Ask clarifying questions out loud : Just as you would do in a live case interview, ask clarifying questions out loud. Although you do not have a case partner that can answer your questions, it is important to practice identifying the critical questions that need to be asked to fully understand the case
  • Structure a framework and present it out loud : Pretend that you are in an actual interview in which you’ll only have a few minutes to put together a comprehensive and coherent framework. Replicate the stress that you will feel in an interview when you are practicing case interviews on your own by giving yourself time pressure.

When you have finished creating your framework, turn your paper around to face an imaginary interviewer and walk through the framework out loud. You will need to get good at presenting your framework concisely and in an easy to understand way.

  • Propose an area to start the case : Propose an area of your framework to start the case. Make sure to say out loud the reasons why you want to start with that particular area
  • Answer each case question out loud : If the question is a quantitative problem, create a structure and walk the interviewer through how you would solve the problem. When doing math, do your calculations out loud and explain the steps that you are taking.

If the question is qualitative, structure your thinking and then brainstorm your ideas out loud. Walk the interviewer through your ideas and opinions.

  • Deliver a recommendation out loud : Just as you would do in a real case interview, ask for a brief moment to collect your thoughts and review your notes. Once you have decided on a recommendation, present your recommendation to the interviewer.

3. Follow best practices while practicing case interviews :    

You’ll most likely be watching, reading, or working through these case interview examples by yourself. To get the most practice and learnings out of each case interview example, follow these tips: 

  • Don’t have notes or a calculator out when you are practicing since you won’t have these in your actual interview
  • Don’t take breaks in the middle of a mock case interview
  • Don’t read the case answer until you completely finish answering each question
  • Talk through everything out loud as if there were an interviewer in the room
  • Occasionally record yourself to understand what you look like and sound like when you speak

4. Identify improvement areas to work on

When the case is completed, review your framework and answers and compare them to the model answers that the case provides. Reflect on how you could have made your framework or answers stronger.

Also, take the time to reflect on what parts of the case you could have done better. Could your case synthesis be more concise? Was your framework mutually exclusive and collectively exhaustive? Could your math calculations be done more smoothly? Was your recommendation structured enough?

This is the most important part of practicing case interviews by yourself. Since you have no partner to provide you feedback, you will need to be introspective and identify your own improvement areas.

At the end of each practice case interview, you should have a list of new things that you have learned and a list of improvement areas to work on in future practice cases. You’ll continue to work on your improvement areas in future practice cases either by yourself or with a partner.

5. Eventually find a case partner to practice with

You can only do so many practice case interviews by yourself before your learning will start to plateau. Eventually, you should be practicing case interviews with a case partner.

Practicing with a case partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner:

  • Driving the direction of the case
  • Asking for more information
  • Collaborating to get the right approach or structure
  • Answering follow-up questions

If you are practicing with a case partner, decide who is going to be giving the case and who is going to be receiving the case.

If you are giving the case, read the entire case information carefully. It may be helpful to read through everything twice so that you are familiar with all of the information and can answer any question that your partner asks you to clarify.

As the person giving the case, you need to be the case expert.

You should become familiar with the overall direction of the case. In other words, you should know what the major questions of the case are and what the major areas of investigation are. This will help you run the mock case interview more smoothly.  

Depending on whether you want the case interview to be interviewer-led or candidate-led, you will need to decide how much you want to steer the direction of the case.

If your partner gets stuck and is taking a long time, you may need to step in and provide suggestions or hints. If your partner is proceeding down a wrong direction, you will need to direct them towards the right direction.

Where to Find More Case Interview Examples

To find more case interview examples, you can use a variety of different case interview prep books, online courses, and coaching. We'll cover each of these different categories of resources for more case interview practice in more detail.

Case Interview Prep Books

Case interview prep books are great resources to use because they are fairly inexpensive, only costing $20 to $30. They contain a tremendous amount of information that you can read, digest, and re-read at your own pace.

Based on our comprehensive review of the 12 popular case interview prep books , we ranked nearly all of the case prep books in the market.

The three case interview prep books we recommend using are:

  • Hacking the Case Interview : In this book, learn exactly what to do and what to say in every step of the case interview. This is the perfect book for beginners that are looking to learn the basics of case interviews quickly.
  • The Ultimate Case Interview Workbook : In this book, hone your case interview skills through 65+ problems tailored towards each type of question asked in case interviews and 15 full-length practice cases. This book is great for intermediates looking to get quality practice.
  • Case Interview Secrets : This book provides great explanations of essential case interview concepts and fundamentals. The stories and anecdotes that the author provides are entertaining and help paint a clear picture of what to expect in a case interview, what interviewers are looking for, and how to solve a case interview.

Case Interview Courses

Case interview courses are more expensive to use than case interview prep books, but offer more efficient and effective learning. You’ll learn much more quickly from watching someone teach you the material, provide examples, and then walk through practice problems than from reading a book by yourself.

Courses typically cost anywhere between $200 to $400.

If you are looking for a single resource to learn the best case interview strategies in the most efficient way possible, enroll in our comprehensive case interview course .

Through 70+ concise video lessons and 20 full-length practice cases based on real interviews from top-tier consulting firms, you’ll learn step-by-step how to crush your case interview.

We’ve had students pass their consulting first round interview with just a week of preparation, but know that your success depends on the amount of effort you put in and your starting capabilities.

Case Interview Coaching

With case interview coaching, you’ll pay anywhere between $100 to $300 for a 40- to 60-minute mock case interview session with a case coach. Typically, case coaches are former consultants or interviewers that have worked at top-tier consulting firms.

Although very expensive, case interview coaching can provide you with high quality feedback that can significantly improve your case interview performance. By working with a case coach, you will be practicing high quality cases with an expert. You’ll get detailed feedback that ordinary case interview partners are not able to provide.

Know that you do not need to purchase case interview coaching to receive a consulting job offer. The vast majority of candidates that receive offers from top firms did not purchase case interview coaching. By purchasing case interview coaching, you are essentially purchasing convenience and learning efficiency.

Case interview coaching is best for those that have already learned as much as they can about case interviews on their own and feel that they have reached a plateau in their learning. For case interview beginners and intermediates, it may be a better use of their money to first purchase a case interview course or case interview prep book before purchasing expensive coaching sessions.

If you do decide to eventually use a case interview coach, consider using our case coaching service .

There is a wide range of quality among coaches, so ensure that you are working with someone that is invested in your development and success. If possible, ask for reviews from previous candidates that your coach has worked with.
