Why Most Candidates Fail Their Investment Banking Interviews (and How to Avoid It)

Why Most Candidates Fail Their Investment Banking Interviews (and How to Avoid It)

Breaking into investment banking isn’t easy. Every year, thousands of ambitious students prepare for interviews with bulge brackets and elite boutiques. They spend months memorizing technical guides, grinding through accounting flashcards, and practicing DCFs until they can do them in their sleep.

And yet — most still fail.

So why does this happen? And more importantly, how can you avoid being one of them?

1. Over-focusing on Technicals

Yes, you need to know your accounting, valuation, and financial modeling. But technicals are only one piece of the puzzle. Banks are hiring people, not spreadsheets. If you can’t explain why you want the job, or if your story doesn’t connect, you won’t get the offer — no matter how perfect your LBO math is.

2. Weak Personal Storytelling

Your “walk me through your resume” answer is the single most important response of your entire interview. It sets the tone, frames your strengths, and shows if you actually fit. Too many candidates sound robotic, like they’re reading off a script. You need clarity, flow, and a touch of authenticity.

3. Lack of Behavioral Prep

Interviewers want to know how you think, not just what you know. “Tell me about a time you worked in a team” isn’t a filler question — it’s your chance to show you have the grit and emotional intelligence to survive 90-hour weeks.

4. Not Practicing Out Loud

It’s one thing to know the answers. It’s another to say them smoothly under pressure. The best candidates simulate the real interview environment — speaking out loud, timing their responses, and getting feedback.
