Learn Excel and Business Finance, and practice investment banking interviews, by doing, not watching. Interactive lessons, drills, spoken practice, and AI mock interviews. Start for free. No account required.
INTERVIEW PREP (INVESTMENT BANKING)
An AI interviewer that never warms up asks the standard IB questions and you record your answer. Every answer gets an honest read on your composure, measured from the pauses, restarts, and recoveries in your audio: did you hold, recover, or freeze. Clearly wrong finance gets flagged.
• Mock interviews: a realistic session with follow-ups, up to 3 a day.
• Technical reps: say a classic walkthrough and get graded against the key points.
• Behavioral reps: rehearse your stories and build a story bank that covers the standard fit questions.
• Lessons and drills across 7 IB topics, from accounting to LBOs, 486 questions in all.
• Set your interview date and the daily plan paces what to learn, drill, and rehearse until then.
You can type any answer instead of speaking. Feedback is AI-generated practice, not career advice, and no app can promise you an offer.
