Check the AI
Each case gives you a written example of an AI assistant's draft analysis with planted mistakes. Find them, fix the numbers, and name what it missed.
Practice in a similar format, not the real test. No firm's test is copied or reproduced. What the real formats look like, official and reported: AI-assisted case interviews.
Follow each firm's rules on AI
Bain's official assessment page says AI tools are strictly prohibited during its online test, including recording, screenshots, and any software that transcribes or gives feedback. Meanwhile, some firms now pilot interviews where you are asked to use an AI tool the firm provides. Read every invitation closely, and use outside AI help only when the firm clearly allows it.
