Callback AI

Callback is finance interview prep for investment banking, private equity and venture capital — built the way a desk actually tests you. Free to start, and the free tier is a real one: you get questions in every one of the fourteen technical areas, not three areas and a wall. Every question carries a key takeaway, a full explanation, and a note on what the interviewer is really testing. Nothing is locked behind grinding through the basics — if you already know accounting, you can start on LBO on day one. WHAT MAKES IT DIFFERENT Numeric drills, not just flashcards. A purpose-built keypad, because in a real interview you are asked to compute, not to recognise. Frequency first. Every question is tagged with how often it actually comes up, and the ones you cannot avoid come first. A plan keyed to your interview date. Four phases from first pass to final polish, adapting as your mastery moves. Mock interviews you answer out loud. Pick one interviewer or sit a full superday — junior to senior, no break. Each seat has its own areas, pace and difficulty. Spoken answers are transcribed on your iPhone, and on an Apple Intelligence iPhone they are marked there too. Feedback is held to the end, like the real thing. Level calibration. Tell us where you stand and we believe you — then quietly verify with easier probes mixed into your day. Nothing is ever locked behind progress. An AI tutor that knows the syllabus. Ask a follow-up on any card and have it worked through rather than looked up. The tutor is answered by Callback, so every iPhone gets the same one — it is part of Pro, and the single part of the app that needs a sign-in and a connection. Live markets. The rates you get asked to quote, straight from the ECB, the Bundesbank, the US Treasury and the New York Fed — cached, so they still show on a plane. THE FOURTEEN AREAS Accounting · EV & Equity Value · Valuation · DCF · M&A · LBO · Fit & Story · Brainteasers · Markets & Products · Debt Capital Markets · Equity Capital Markets · Restructuring · Private Equity · Venture Capital FREE AND PRO Free gives you a genuine sample of every area, aptitude practice, and a daily plan built from it. Callback Pro opens the rest: every question in every area, the AI tutor, timed aptitude tests with a scored report, mock interview rounds, and the full plan through to your interview date. The split is by depth, never by grinding. WHO IT IS FOR Students and analysts preparing for summer analyst, off-cycle and full-time recruiting at investment banks, private equity funds and venture funds — and anyone sitting a technical finance interview who would rather be asked to compute than to recite. PRIVACY What you study stays on your iPhone. Your questions, answers, scores, plan and mock transcripts are never uploaded, and audio from a spoken answer is never stored — what survives an answer is text, on your device. The one exception is the AI tutor. What you ask it and what it answers are handled on Callback's server, and kept so a conversation has a history, which is why that feature — and only that feature — asks you to sign in. SUBSCRIPTION Callback Pro is an optional subscription, offered weekly, monthly or quarterly. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple Account settings.
