- 75+ simulations
- 1,300+ practice questions
- 60+ free cases
- Free demos, no card
Why DrillCase exists
The online test comes before any interview, and it is a different test at each firm
Candidates prepare for case interviews for months, then meet an unfamiliar screen first. We built DrillCase for that step.
Each firm sends a different test
McKinsey sends Solve, a set of ecology-themed games. BCG usually sends Casey, a chatbot-led case. Bain sends a Sova or TestGorilla reasoning test. Practicing for one does not cover the others.
The clock is the hard part
The math is rarely advanced. What costs candidates is reading exhibits and deciding under a timer, often with no way back to an earlier question.
Most prep material is not in the format
A PDF case or a textbook drill does not look or behave like a chatbot, a game or a timed aptitude screen. The first time you see the real interface should not be test day.
What we built
Practice that looks and behaves like the test
Each simulator copies the shape of the real screen: the chat, the exhibits, the timer and the one-way answers. Then it scores you, answer by answer.
Attempt, score, review, repeat
Practice only helps if you learn from the miss. Every attempt ends with a score you can review answer by answer, and Casey-style cases add a downloadable answer key. Then you take the next timed set with the gaps in mind.
Proof you can check
