What is a Case Interview?
A case interview is the analysis of a business question. Unlike most other interview questions, it is an interactive process. Your interviewer will present you with a business problem and ask for your opinion. Your job is to ask the interviewer logical questions that enable you to make detailed recommendations. In this context, the interviewer is attempting to assess your ability to synthesize the elements of the problem into a coherent and cohesive solution.
Case interviews evaluate your skills in several areas:
How you approach a problem
- Structured, logical thinking
- Organization and detail orientation
- Comfort with numbers (Math major not required)
- Ease of communication
- Conﬁdence and poise
Enthusiasm for problem-solving
What do you know about business
- Business intuition
- A few, fundamental business concepts and frameworks
Students and Alumni may only schedule one mock case interview with the Center for Career Education per semester.
What happens during a Case Interview?
During the interview, you will likely be asked to answer at least one of three types of questions:
- Brain Teaser: such as, “Why are manhole covers round?”
- Market Sizing: such as, “How many dry cleaners are there in New York City?”
- Business Case: such as, “Your client is one of the leading manufacturers of bathroom taps and ﬁxtures. Recently, it has noticed a decline in proﬁts. Why are the proﬁts declining? What can the client do?”
How should I approach the Case Interview?
Use RASCALS — Repeat, Ask, Stop, Construct, Answer, Loosen Up and Summarize Repeat
- Listen to the question
- Rephrase what you hear
- Make sure you and the interviewer are on the same page about the question
- Ask as many clarifying questions as you can about the problem
- Use this time to show enthusiasm. If the product you are discussing is tires, think about tires. Get interested in tires. Show this through your questions.
- Ask your interviewer “Do you mind if I take 30 seconds to step back and collect my thoughts?”
- PAUSE. BE SILENT. THINK. (It may feel awkward, but your interviewer will see this as a sign of maturity and conﬁdence)
Structure your response. Write it down
Think of each point you want to make as the topic sentence in a paragraph. Give an overview of what you will say, and then say it
Use headlines to describe what you are thinking (e.g. talk in topic sentences)
Converse with the interviewer about the approach you have devised
Let your answer feel like a conversation — as if you are making a recommendation to a client
Show conﬁdence in your answer
Show enthusiasm in the topic
Show interest in asking for feedback from the interviewer on your approach
Articulate your conclusion
Reiterate your main points
Highlight the most important parts of the conversation (so the interviewer remembers!)
