What is a Technical Interview for Investment Banking?

A technical interview in Investment Banking assesses your quantitative skills and understanding of financial concepts. This goes beyond theoretical knowledge to evaluate how you apply those concepts in real-world scenarios, such as valuing a company or analyzing a potential merger.

For example, expect questions on discounted cash flow (DCF) analysis, leveraged buyouts (LBOs), and merger & acquisition (M&A) transactions. The interviewer wants to see how you think under pressure, not just recite formulas.

You can build proof through academic projects, internships, and self-directed learning.

What if I don’t know the answer to a question?

This demonstrates your problem-solving skills and intellectual honesty. You can also ask clarifying questions to gain a better understanding of the question.

Be prepared to answer questions about your experience working in teams, handling difficult situations, and managing your time effectively.

What is the best way to follow up after the interview?

Send a thank-you note to the interviewer within 24 hours of the interview. Express your gratitude for their time and reiterate your interest in the position.
