It’s a simple and easy way to see whether you understand the realities of the industry, the role you’re applying for and to what extent you are committed to the work.

It’s the same with investment banking. Your interviewer wants to know that you fully understand what will be required of you if you're hired, and what investment bankers do.

Investment banking is known for its high-pressure environments, long working hours and established hierarchy. Graduates and juniors can expect to have a working week significantly longer than average, extensive workloads and last-minute requests from senior staff.

There’s also a steep learning curve for new employees, as they learn to scrutinise data and rapidly develop soft skills so they can communicate effectively and concisely.

This means the question “Why investment banking?” is a good way for an interviewer to work out whether you’re aware of the structure and style of this work.

They can also use it to understand whether you are committed to the role and the industry, or if you aren’t aware of the full range of challenges involved.
