BCG Case Interview: What to Expect and How to Prepare

BCG's case interviews tend to feel more conversational than McKinsey's — closer to a working discussion with a colleague than a scripted Q&A — but the underlying skill being tested is the same: can you structure an ambiguous business problem clearly.

Format

BCG cases lean candidate-led: after an initial prompt, you're expected to drive the structure, propose next steps, and steer the conversation, with the interviewer pushing back, adding information, or challenging your logic as you go. Many candidates also complete an online assessment (often referred to as BCG Casey) earlier in the process.

What's evaluated

  • Structuring under a conversational format — can you build and communicate a MECE structure while also responding naturally to follow-up questions and new information?
  • Business intuition — BCG interviewers often reward candidates who bring real business judgment to a case, not just a mechanically correct framework.
  • Comfort with ambiguity — BCG cases are frequently built to be less templated than a typical textbook case, testing whether you can adapt on the fly.
  • Communication as a two-way conversation — since the format is less scripted, clearly narrating your thinking matters even more than in a strictly interviewer-led case.

How to prepare

  1. Practice driving a case, not just answering prompts. Since BCG leans candidate-led, get comfortable proposing your own next step rather than waiting to be asked — see How to Structure a Case Interview.
  2. Practice adapting frameworks live, since BCG cases are often deliberately not a clean match for a standard template — see Why Memorizing Case Interview Frameworks Doesn't Work.
  3. Cover the core case types. Profitability, market entry, and M&A all come up regularly at BCG.
  4. Practice narrating your structure out loud, since the conversational format rewards clear communication as much as the structure itself.

Practice the candidate-led format

Because BCG expects you to drive the case, practicing on prompts where you build the structure from scratch — not just fill in a template — matters more than usual. Practice case structuring on Meceify →

FAQ

Does BCG use candidate-led or interviewer-led cases?

BCG generally favors a more candidate-led, conversational style compared to McKinsey's interviewer-led format. You're expected to drive the structure and the conversation, with the interviewer probing and pushing back along the way.

Does BCG require a written test before interviews?

BCG typically uses its own online case-style assessment (the BCG Casey chatbot-style test in many markets) earlier in the process, in addition to live case interviews.
