How to Answer the IB Interview Questions Interview Question
Prepare bucket by bucket:
- Fit. "Why IB" = the work itself: live transactions, steep learning, client exposure. "Why us" = specific deals, people, or culture — never generic.
- Accounting. Walk a transaction through all three statements. Know working capital, depreciation's three effects, and how $10 of depreciation flows everywhere.
- Valuation. DCF steps with intuition; trading comps and precedent transactions; EV vs. equity value; key multiples (EV/EBITDA, P/E) and when each applies.
- Deals. Accretion/dilution intuition; LBO basics (leverage amplifies returns); one recent deal you can discuss with a real opinion.
The bar: every technical answer under 90 seconds, every fit answer specific, every claim backed by intuition — that is what 'banker-ready' sounds like.
Common Mistakes With the Ib Interview Questions Interview Interview Question
- Memorizing formulas without intuition: 'WACC is...' with no sense of what drives it.
- Generic 'why IB' answers about prestige or money — bankers hear it daily and discount it.
- No deal to discuss: always have one recent transaction prepared, with a view on why it made sense.
