How to Prepare for an Interview Case Interviews

The case interview is a unique and challenging process that enables the recruiter to assess the candidate’s analytical and creative skills. Typically, consulting and investment banking firms utilize the case interview at some point in the interview process, although more and more marketing and finance companies are adopting this strategy in their own recruitment efforts.

Preparing for the Interview

There is only one good way to prepare for a case interview, and that is PRACTICE!

When interviewing with a firm, try to keep in mind the type of work that they do since the interview cases will reflect the particular company’s area of expertise. Also, talk to students or alumni who have interviewed with the firm before and ask what type of questions they were asked. Here are additional tips and steps you can follow to continue to prepare:

Estimation Cases

In estimation cases you are asked to come up with an “educated guess” of some number, such as the classic, “How much does a Boeing 747 weigh?” While the questions may sometimes seem “off the wall,” estimation is an important skill to possess in consulting work. As a consultant, you will often have to make decisions based on incomplete or unavailable data, in which case it becomes important to generate reasonable estimates. In these types of exercises it is not important whether your assumptions are right or wrong, but to make sure that your estimates are at least reasonable based on common sense. For example, if one of the assumptions you make is about the U.S. population, do not say that you assume it is 10 million. Estimation problems are based on logical reasoning applied to a number of known data points (your assumptions) to arrive at the desired answer. Since your logic is what is tested, lay it out clearly for the interviewer. Before you start making assumptions, tell the interviewer what your logic is going to be to figure out the answer.

Mini Cases

Mini cases are typically short and focus on a single problem. Often, the goal is to come to a solution rather than uncover the underlying causes of a problem. To solve these problems, it is recommended that you first define what the characteristics of the desired outcome would be. Then, brainstorm the ways that the company could deal with their problem; use this as an opportunity to be creative. Finally, tackle each idea in turn, drawing out the possible issues involved and setting them against the criteria for the desired outcome (i.e., to avoid high expenditures). After evaluating each of the ideas you have generated, choose a solution from among those that meet all of the desired criteria

Business Cases

Business cases are generally longer than mini cases (20 to 30 minutes typically) and test your business skills in addition to your logical reasoning skills. Much of your core course work is applicable in these cases. Consulting firms rely heavily on general business knowledge and expect you to be able to integrate the concepts from your courses in analyzing a business situation. A case interview is typically an interactive process and most likely the interviewer will volunteer additional information as the interview progresses or when you ask questions. It is important to gather as much information as you need. The amount of information you receive up front can differ greatly depending on the style of the interviewer and the type of case you get. It may make sense to jot down some quick notes to help you remember the pertinent facts. Other interviewers start out with a simple two sentence summary and expect you to probe for more information by asking thoughtful questions. Remember, it is acceptable to ask questions. One of the most valuable skills of a successful consultant is the ability to ask the right questions. On the other hand, be careful not to spend too much time asking a lot of factual questions. It may become difficult for the interviewer to follow your logic and you may seem to be taking a shotgun approach to solving the problem. Keeping that in mind, always make sure that you think out loud so the interviewer understands how you are formulating your questions. The critical skill being evaluated in the business case interview is whether you can solve a business problem in a logical and coherent fashion. It is important not to ramble and jump from one hypothesis to the next, but rather to use a logical framework to attack the problem. Think logically about a good way to approach the problem. You can take some time on this. It is no problem to be silent for a moment while you consider your approach. This makes you look thoughtful and is much better than starting to ramble and run around in circles.

Some examples of frameworks and possible problems to which they apply are given below.

Income Statement: A simple income statement is often a very valuable framework to use. By analyzing profitability through its component factors such as revenues, cost of goods sold, and operating expenses, you can quickly pinpoint the direction in which to focus your analysis.

Four Cs: To analyze a company’s strategy in terms of its chosen market position, you have to evaluate the different factors that will determine its success.
