How to tackle a case study

First round interviews (for investment banking and global markets) will involve a case study.
Case study interviews are designed to show us your problem-solving skills and analytical thinking. We'll also be looking at how you present yourself and how good your communication skills are under pressure.

Why use case studies?

We use case study interviews because they provide us with insights into your thought processes. Problem solving is often independent of any particular subject expertise you may have and we want to see how you would tackle any of a very wide range of potential case study questions. We're interested in your expertise in general business, your ability to apply your formal education and work experience in an analytical and creative way, and your raw intelligence.

What kind of questions should I expect?

Often a case study is business-related, but it could touch on anything - the question is not designed to test any previously acquired knowledge or experience. You'll be asked to prepare an exercise from information given to you when you arrive at the interview. You'll have between 45 and 60 minutes to read the data and compile your notes. You'll then be asked to make recommendations. Remember, there are no right answers. You should consider all lines of argument and then present one as your chosen opinion, mentioning why you discarded the other possibilities.

How to do well

• Practice extensively beforehand. Research case study examples on the internet and use them to build your experience.
• Ensure that you are able to present your pitch concisely and articulately. You will have a very limited time to get the main points across before the interviewer starts asking you questions on your rationale.
• Listen carefully to the question. If you like, repeat it back to your interviewer to make sure you have understood fully.
• Don't jump into your answer immediately. Take a moment to collect your thoughts, and get ready.
• Remember that we are not looking for a ‘correct' answer. It is the route you have taken to reach your answer that is important to us.
• Ask questions. Asking the right questions will be key to proving that you have the analytical skills we expect. The interview is meant to be interactive.
• Construct a logical framework with which to explore the critical issues of the case.
  Prioritize the issues and objectives. Don't get bogged down trying to deal with every aspect.
• Don't be afraid to think outside the box. Creativity is seen as a major asset at Nomura.
