IB Reps is a flashcard trainer for investment banking interviews. It covers technical and behavioral questions, and has you practice answering them out loud.

408 cards, 12 topics

From Accounting and Valuation & DCF to M&A, LBOs, Restructuring and Your Story.

“Say this” answers

Every card has a spoken model answer, so you rehearse saying it, not just reading it.

Spaced repetition

Cards come back when they’re due, and your weak spots get extra review.

Paced to your interview

Set your interview date and a daily goal, and the Today screen paces you to it.

Approach

How we build

A few rules every Elpis Labs app follows.

One job per app

Each app does one thing well. IB Reps is for interview prep and nothing else, so there’s nothing to wade through.

Built around practice

Reading an answer isn’t the same as giving it. Our apps get you answering, saying it out loud, and repeating what you missed.

Small on purpose

We’re a small studio. The people who build the apps are the same people who answer your email.
