What is IB Offer?
IB Offer is an AI interview coach built specifically for investment banking candidates. Instead of reading through a static question guide and hoping your answer lands, you answer real technical questions out loud or in writing and get an AI-graded response with specific feedback and a model answer to compare against.
The platform covers the technical ground that IB interviews actually test: accounting, EV and equity value, valuation and comps, DCF, LBO, M&A and accretion, markets and brainteasers, restructuring, and behavioral questions. It also spans adjacent tracks like private equity and corporate finance, so the same engine works whether you're targeting an M&A advisory seat or a PE role.
With 1,100+ drills, 35 sourced firm guides, and nine domains, IB Offer is designed around repetition rather than passive review. The loop is simple: answer the question, read the grade, fix the gap, do the next rep.
Who it's for
- IB recruiting candidates — anyone prepping for technical interviews at investment banks who needs scored reps rather than another PDF.
- PE and corporate finance hopefuls — candidates whose interviews lean on the same accounting, valuation, and LBO fundamentals.
- Self-directed studiers — people who want structured practice at any hour, without booking a paid coach per session.
Key features
AI-graded technical drills
Every graded drill returns specific feedback on your technicals and structure, not just a generic score. It pinpoints what to fix before your next round, and each rep comes with a model answer you can compare against.
Ask IB coaching
Ask IB handles follow-up questions when a concept is unclear, so you can clear up a gap in the moment instead of moving on with a half-understood answer.
35 sourced firm guides
Firm-specific preparation covers recruiting at particular banks, letting you tailor your practice to the employers you're actually targeting.
Free tools
Mental math drills and a DCF checker are available as free tools, alongside unlimited Mental Math on free accounts.
What stands out
A PDF tells you the answer. IB Offer grades yours.
That distinction is the whole product. Most prep material gives you the correct response and leaves you to judge your own attempt, which is exactly where candidates misjudge themselves. IB Offer closes that loop by scoring your answer and naming what's missing, then handing you a model answer as the benchmark. It sits in the gap between a question guide and a paid coach — the reps in between, available whenever you have fifteen minutes.
