Interview prep · BCG

Practise BCG case interview questions.

AI-graded guesstimate practice for BCG candidate-led case interviews. Build the structuring + estimation muscle BCG grades on.

What the BCG loop actually looks like.

BCG cases are typically candidate-led: you drive, they evaluate. Expect a market-entry / profitability / pricing / market-sizing prompt; you propose a structure; they steer where you go from there. Online assessments (OAs) include video and timed PSGs depending on office.

What separates offers from rejections at BCG.

  1. 1

    Drive — but stay flexible. If the interviewer steers, follow gracefully.

  2. 2

    Practise structuring out loud. Recording yourself helps.

  3. 3

    For estimation, top-down + bottom-up cross-check is a high-signal move.

  4. 4

    Always end with a clean recommendation: "My answer is X, supported by Y, and the risk is Z."

Train the muscle, not the answer.
