Investment Banking Interview Questions: How to Prepare

Investment banking interviews are notoriously demanding — not because the questions are obscure, but because they test technical precision, commercial awareness and composure all at once. The good news is that they are highly predictable, so disciplined preparation pays off enormously. Here is what to expect and how to prepare.

The three types of questions

Almost every investment banking interview draws from three buckets: technical questions (accounting, valuation and finance), behavioural and "fit" questions (why banking, why this firm, teamwork and resilience), and commercial or "market" questions (a recent deal, a stock you would pitch, what is happening in markets). Strong candidates prepare deliberately for all three rather than over-indexing on technicals alone.

Technical questions to master

The technical core is well defined. Expect to walk through the three financial statements and how they link, explain a discounted cash flow (DCF) from start to finish, discuss valuation multiples and comparable company analysis, and handle enterprise value versus equity value. Accounting questions — such as how a change in one statement flows through the others — are common, as are questions on weighted average cost of capital and how different events affect a valuation. If you are still building these foundations, our guides to what investment banking is and how to become an investment banker are good starting points.

Behavioural and fit questions

Banks want to know you understand the job, will stick at it, and work well in a team under pressure. Prepare crisp, honest answers to "why investment banking", "why our firm", "tell me about a time you worked in a team" and "how do you handle pressure". Use structured, specific examples rather than generalities, and make sure your motivation sounds genuine rather than rehearsed. Fit matters more than candidates expect — interviewers are imagining long hours working alongside you.

Commercial awareness

You should be able to discuss a recent deal or market development intelligently, and many interviews ask for a stock pitch — a company you would invest in and why. This tests whether you actually follow markets rather than just want the salary. Reading the financial press consistently in the weeks before interviews is the simplest way to prepare.

How to prepare effectively

Three habits separate strong candidates: drilling the technical questions until your answers are automatic, preparing and rehearsing your behavioural stories, and staying current on markets. Mock interviews — ideally with someone in the industry — are invaluable for building composure. Underpinning all of it is solid technical knowledge, which structured study like our finance CPD courses can help you build before you face the room.

A realistic preparation timeline

Most successful candidates start preparing several weeks ahead rather than cramming. A sensible rhythm is to spend the early weeks mastering the technical core until your answers are fluent, the middle period rehearsing behavioural stories and building a stock pitch, and the final stretch on mock interviews and staying current with market news. Spreading it out matters because interviews test recall under pressure, and fluency only comes from repetition. Treat every mock as the real thing, ask for blunt feedback, and keep a running list of the questions that caught you out so you can close those gaps before the real interview.

Frequently asked questions

What technical questions are most common in IB interviews?

Walking through a DCF, explaining how the three financial statements link, valuation multiples and comparable company analysis, and enterprise versus equity value are among the most common.

How important are behavioural questions?

Very. Banks assess fit and resilience as seriously as technical skill, because the work involves long hours in close-knit teams. Prepare specific, structured examples.

Should I prepare a stock pitch?

Yes. Many interviews ask for one to test genuine commercial interest. Have a company you can discuss with conviction and clear reasoning.

In short: investment banking interviews are demanding but predictable — master the technicals, rehearse your fit stories, follow the markets, and practise under pressure.
