Challenging cases you can work through on your own.
Practice on your own, then check your thinking against a sample answer.
Inspired by real consulting insights
Cases draw on McKinsey, BCG, and Bain insight articles. Read the real article after each case.
Three levels of difficulty
Beginner, Intermediate, and Final round readiness. Start where you are today.
Exhibits that challenge you
Complex charts like the ones that catch candidates off guard in real interviews.
For a good cause
ChocolaCase is free. In return, we kindly invite you to give $5 to a nonprofit you care about, so the help you get here reaches someone else too.
Built for self practice. It does not replace live mocks with another person, so keep doing those too.
One small ask before you begin.
There is no fee to use this tool. If you are able, we invite you to give $5 to a nonprofit you care about, so the help you find here can reach someone else too. Choose one of our suggestions or any cause close to your heart.
We can't check, and we won't. But the universe keeps its own books.
What are we drilling today?
Short podcast style episodes on what to know about each industry before a case: how companies make money, what drives their costs, and what is changing right now.
Episodes are created with the help of AI. Double check key facts before relying on them in an interview.
The interviewer reads the case background and each question aloud. The written version appears with the sample answer.
Designed for self practice. It does not replace live mock interviews with another person.
