IB interview practice with AI. Walk through deal experience, pitch stocks, explain valuations — timed pressure and instant feedback.
Investment banking interviews are notoriously rigorous, combining technical finance questions with behavioral assessment. The process often includes multiple rounds testing accounting knowledge, valuation methods, deal experience, and cultural fit. Preparation is non-negotiable—underprepared candidates are eliminated quickly.
Technical questions test accounting fundamentals (three financial statements, how they connect), valuation methods (DCF, comparable companies, precedent transactions), and M&A mechanics. You should be able to walk through a DCF model, explain purchase price allocation, and discuss recent deal activity in your target sector.
Behavioral questions in banking focus on "why banking," commitment to the demanding lifestyle, teamwork under pressure, and attention to detail. Banks want candidates who understand what they're signing up for—100-hour weeks during deals—and are genuinely motivated, not just attracted to compensation.
Investment banking interviews evaluate technical competence, motivation, and "fit"—whether you'll thrive in the demanding culture.
Technical competence is table stakes. You must know accounting, valuation, and M&A fundamentals. Stumbling on basic questions signals you haven't prepared seriously—and banking rewards preparation above almost everything else.
Motivation assessment determines whether you'll persist through difficult periods. "Why banking?" requires a thoughtful answer about learning, transaction exposure, and career goals. Generic answers about "finance interest" fall flat. Know why you specifically want this bank and group.
Fit evaluation happens constantly. Are you someone seniors want on their deal team at 2 AM? Do you communicate clearly under pressure? Are you coachable? Banks reject technically strong candidates who seem difficult to work with or likely to burn out.
Attention to detail shows through your interview performance. Typos in your resume, imprecise language, or sloppy case study work signals you'll produce sloppy work on actual deals—a non-starter in a business where errors can cost millions.
What technical questions are asked in investment banking interviews?
Core technical questions: "Walk me through the three financial statements and how they connect," "Walk me through a DCF," "How do you value a company?", "What happens to each statement when depreciation increases by $10?", "Walk me through an LBO," and deal-specific questions about recent transactions.
How do I answer "Why investment banking?"
Connect three elements: (1) What specifically attracts you to transaction work (deal exposure, variety, learning pace), (2) Why this bank and group specifically (culture, deal flow, people you met), (3) How this fits your longer-term goals. Avoid mentioning compensation as primary motivation—it signals you'll leave when better offers come.
How much technical preparation do I need?
Significant. Know the "400 Questions" guides thoroughly. Be able to walk through valuation methods, explain accounting relationships, and discuss M&A mechanics. Practice until answers are automatic—hesitation on basic technicals is disqualifying. Plan for 50-100 hours of preparation.
How important is fit in banking interviews?
Critical. Banks reject technically competent candidates who seem difficult to work with, likely to burn out, or culturally misaligned. Show you understand the lifestyle demands, can work collaboratively under pressure, and have genuine enthusiasm for the work. Arrogance is a red flag despite the industry's reputation.
