The case interview is the ultimate challenge for most consulting candidates. Whether you’re just starting your preparation or you are 30 practice cases in, it’s always helpful to familiarize yourself with the most popular case interview frameworks. However, the goal is not to memorize the case study interview frameworks. You must understand each well enough to know when they apply and how to blend them to create your own frameworks.
It's always a red flag for an interviewer if a candidate tries to improperly cram a business situation into a framework. Instead, you need to know how to mix and match across the framework categories to create your own custom approach to solve the problem at hand. Enjoy this breakdown of case study interview frameworks - and apply wisely!
Again, always remember that the best candidates create unique frameworks for each of their cases. When you are structuring your thoughts during a case interview, pick and choose the relevant parts of these frameworks that you think will help solve your client’s problem. The best case interview frameworks are the ones that will help you solve your client's problem.
Use Of Case Interview Frameworks
In this and the following articles (links at the end), we will give an overview of the frameworks we use both for interviews and on-the-job at MC. We'll cover what they are and how you can get to know them well enough to use them. In the subsequent articles, we’ll explore each one in more detail.
For each framework, we will give you:
- Knowledge of the underlying business concepts
- The questions they are supposed to address
- How to identify when to use them in a case
- How to best deliver them
- How to apply them creatively
Why Case Interview Frameworks Matter
If you've heard about different frameworks from different places, why should you care about these?
- Our frameworks enable you to solve absolutely every case, so make sure you understand them in depth.
- The frameworks are useful for real-life consulting projects, not just sterile academic case-prepping.
- You could memorize 12 or 15 or 20 frameworks, but you will not gain expertise in any if you try to use all.
- The frameworks can be mixed and matched; a combo may in fact be the only way to solve the case.
- Remember, these are not comprehensive tools. If you understand how to properly use the concepts in these cases, you will be able to solve any case that is put in front of you.
How To Use Case Interview Frameworks (And How Not To)
Before we give you the intro to case frameworks, here are some guidelines for how best to use them:
- Don’t expect to be given a question that only draws from one of the frameworks. It may well be that you have to borrow from all 4 to break the case down effectively.
- Listen to the question carefully so you can know which framework(s) to use.
- If you don't know for sure, pick one (profitability is a classic go-to) and just get started.
- Be ready for a change of direction! You may be using one framework after the opening, only to have the interviewer ask you a question part way through that allows you to change to another one.
- Do not use the word “framework” in your interview. The moment you use that word, you’re telling the interviewer that you’re going to fit the case into a previously memorized set of rules. Strict rigidity is not your friend.
Frameworks are only a starting point. Remember, this is an intro to case frameworks. These frameworks are really good at helping you come to grips with the concepts being presented. Once you understand what is being asked, adjust them to the case at hand.

Common Case Interview Frameworks:
-
The Profitability Framework
Ultimately, a corporation’s goal is to increase profits. Profits may also be important goals for governments and institutions as well. As a result, profitability remains one of the most common objectives in consulting case study interviews. Knowing how to analyze the major components of profitability is imperative for any aspiring consultant.
The profitability framework is mainly broken into two components: revenue and costs. A profitability view requires looking into both components. Within each of these components, you can structure your framework to analyze the drivers within (price, quantity, variable costs and fixed costs) or the overall situation (big picture and potential solutions).
Additionally, there will be times when your case interviewer states that your client is focused (specifically) on increasing revenue or decreasing costs. You may be tempted to always look at both revenue and costs, but there are many instances when the case is built around only one of those categories. Pay close attention when your interviewer gives you a nudge in the prompt or when answering clarifying questions, and stay laser focused on what the client needs.

The Pricing Framework
Another common case study interview framework revolves around pricing strategy. Generally, prices greatly impact volume and ultimately profits, so this case study objective comes up frequently.
Pricing products and services is a great challenge for companies because prices greatly influence customer decisions. Consulting firms with rich histories and long track records can utilize their work with similar previous clients to provide the guidance needed to get the most out of current clients' pricing strategies.

The 3 C's + Business Situation Framework
The 3C's and business situation framework overlap in categories, so they will be combined in this section. Both case interview frameworks are focused on broad business categories that could be the source of a client’s problem.
The 3Cs focus on the Company, Customers, and Competition. The business situation framework, coined by Victor Cheng, adds Products as an additional category. This combination of categories makes sense with a case involving a focus on understanding both the core elements of the client as well as the competitive landscape.

M&A (Mergers and Acquisitions) Framework
Because they aren’t as common, mergers and acquisitions (M&A) problems often can catch candidates off guard in case interviews. Though you aren’t recruiting for a finance position, it’s still important to have a decent understanding of what M&A case interview frameworks should focus on.
Additionally, a potential merger or acquisition may be a small part of a larger case. For instance, if the company wants to grow, an option the client could be considering is acquiring a smaller competitor. In this case, it will be important for you to be able to structure an M&A framework to systematically discover if this is a good idea for your client.
The first key to nailing an M&A framework question is to understand who the acquirer is. All different types of firms will want to increase cash flow. But the type of acquirer will determine how long of an investment they want to make. Look at the types of acquirers that would influence the term of the investment:
Download the M&A Framework Example here.
Types of M&A Acquirers:
Financial Acquirer- e.g., PE Firm
100% ownership. Typically, the goal would be to sell the company for a quick return. They’ll usually do this by rapidly decreasing costs and increase top-line revenues and profits with cash injections. They’re not looking for a long-term investment.
Financial Investor- e.g., Hedge Fund
Non-majority owner. The goal is that their involvement would positively affect the share value. Once that takes place, they would look to sell the shares for a profit.
Corporate Acquirer- e.g., Multinational Firm
100% ownership. Typically, these types of acquirers will operate the purchased company for a period of time. Additionally, they may have bought the company for a specific purpose and integrate it into their overall company operations.
How To Use The M&A Framework:
With M&A frameworks, remember this key concept. Most of the time, interviews are going to be focused on due diligence strategy. They are looking to understand if one company should buy or invest in another. Look at these 4 key areas:
-
The Target Market
What is the market like? Is it saturated with competitors? Is the market growing, stagnant, or contracting- and why? Obviously, investors are looking for attractive markets. Typically, one of the biggest questions to answer is whether the overall market is big enough for your client’s end goals.
-
The Target Company
This is all about helping your client understand not only if the market is right, but if the company they are looking at buying is the best target company within that market. So you must understand everything about the target company. What are their finances like? Do they have strong profits? What do their forecasts look like? What is their competitive positioning? Are they a top performer, generating strong revenues, or do they have room for improvement with the potential to gain significant market share?
-
Post-Acquisition Strategy
This is really about understanding your clients goals and objectives for the investment, plus how much your client could make over time. The market and the company valuations help you understand how much your client should pay for the target company. So the post-acquisition strategy ties the first two sections together, and also send the message that things will change post purchase..
Is there potential to decrease costs in the target company and increase revenues? Is the culture of the target company conducive to integrating into the purchasing company? Questions like these need to be answered to better understand if the target company would be a beneficial acquisition.
-
Risks and Benefits
Risks and benefits can be a bit more difficult to determine. For example, does the target company have intangible assets, like Intellectual Property? How do you determine the value of their IP? Or what about their management team? Does their management have the capacity to take the company where it needs to go? Are there government restrictions or litigation that they’re experiencing? These types of questions have to be quantified in order for your client to understand if the target company is actually a good value and something that they want to take on.
One bright spot in M&A frameworks is that the recommendations are typically one of the easiest to create because it’s ultimately a yes or no question. And if your answer is yes, your recommendation should be strong and direct! Take a look at our article on the Pyramid Principle to see how to present your recommendation like executives would want it. If you are against the investment then have your details ready as to why not… again, in the Pyramid Principle format. Have your compelling supporting data ready to share, if asked for.
