Case interviews 101

Interviewing is usually a nerve wracking, anxiety inducing experience. Case interviews bring a whole new level of stress and uncertainty. Here are some tips and tricks for tackling the case interview and making the process more manageable.

First things first –what is a case interview?

A case interview is when the employer presents you with a business problem, likely something that the company has to deal with regularly. Your job is to analyze the problem and give some solutions. There is usually no clear right or wrong answer. The interviewer is assessing your problem solving ability, how you approach different situations, and your ability to talk your way through it.

So when I be expected to do a case interview?

If you are interested in consulting or similar fields, you will most likely have to do some variation of a case interview. Sometimes it’ll be one-on-one with an interviewer, other times you will be expected to present your ideas in front of a panel.

Yikes this sounds scary. How do I prepare?

The good news is summer is a great time to prepare for case interviews. Recruiting starts the minute you get back on campus, so you won’t have a lot of time to prepare in the fall. Start by reading some case books and watching videos online to get an idea of what the case interview looks like. Then, find peers to practice with. You can also make an appointment with a career advisor to do a mock case interview. It’s hard to practice for this on your own, so the best strategy is to connect with as many people as possible to practice with each other. There isn’t a magic number for how many to practice, just try to fit as many in.

Okay fine, but what can I do on my own?

There are many things you can do on your own to prepare as well. Brush up on your mental math. I’m not talking calculus here, I’m talking long division and percentages. Keep updated on current business trends, read The Wall Street Journal and The Economist. This will help you come up with unique strategies and solutions. You can also do “case starts.” Read yourself the case prompt, and set up your initial framework to practice how you would start a case.
