Rehearse the BCG interview, in the driver's seat
BCG cases are more candidate-led than most — they want to see you steer, generate ideas, and stay sharp under ambiguity. Some rounds add a written case or brainteaser. Here's how to be ready for all of it.
You set the pace, you make the call
A BCG round leans on your ability to drive a case forward and back it with real commercial judgment — sometimes in writing, against the clock.
Candidate-led cases
You drive. BCG hands you a prompt and expects you to set the structure, ask for the data you need, and move the case forward without being told where to go next.
Judgment & creativity
Frameworks get you in the door; ideas get you the offer. BCG rewards candidates who generate non-obvious options and show genuine commercial instinct, not just clean trees.
Written & brainteaser rounds
Some offices add a timed written case — read a deck, form a recommendation, present it — or a quick brainteaser. Both test whether you think clearly when the clock is loud.
Why is this craft-brewery losing money?
“A regional craft brewery has doubled volume in two years but profit has gone negative. They think the answer is to raise prices. Take it from here.”
What the interviewer is testing
Will you drive without prompting, diagnose before prescribing, and challenge the client's pricing assumption with judgment?
How a strong candidate opens
“Before I touch price, I want to find where the profit is leaking. I'll decompose profit into revenue and cost, and given that volume doubled while profit turned negative, my instinct is that variable cost per unit is scaling faster than price — possibly capacity or distribution. I'd like to see the cost breakdown per unit over those two years. If it confirms that, raising price treats the symptom; the real lever may be unit economics. Can I get the cost data?”
Why it works
It takes the wheel, diagnoses before prescribing, and politely questions the client's pricing reflex — all signs of judgment.
Tuned to the BCG style
Rehearsa hands you the wheel and stays quiet — so you build the habit of driving, the way a BCG case demands.
- Practice owning the case end to end: state your structure, then immediately say which branch you'd pursue first and why.
- Train your 'creative third bucket' — after the obvious revenue and cost levers, force out a non-obvious option a partner hasn't heard ten times.
- Run timed written-case reps: 25 minutes to read a data pack, pick a recommendation, and build three slides of support.
- Get fluent at asking for exactly the data you need next, rather than waiting to be handed an exhibit.
- Rehearse staying calm when the prompt is vague — narrate your assumptions out loud and keep moving instead of freezing.
The round most people skip
Several BCG offices run a timed written case before the final. Rehearsa simulates it: a real data pack, a 25-minute clock, and a forced recommendation with three slides of support — then a graded readout on whether your logic held and your story landed.
