Why these

5 methods, in the order the test asks for them

BCG says to prepare for its online case the same way as for a case interview. What candidates report makes it different is the format: a chatbot that moves one question at a time, no going back, and a recorded pitch at the end.

So the course teaches five decisions in the order Casey asks for them: which data to request, what an exhibit proves, how two tables settle a number, how to set up a big sum, and how to say the answer in 60 seconds.

Every worked example is a question from DrillCase's free demo case. Play it first, then read the lessons as the debrief.

Before you start

What's official, and what's reported

Every claim about the real test is labeled. Checked against our guides and the sources they cite on 23 Sep 2026. If your invitation says something different, trust the invitation.

BCG says: BCG calls it the Online Case Experience: a business case guided by Casey, a chatbot, about 30 minutes, in English. BCG says to prepare as for a case interview.
Candidates report: Candidates report 8 to 10 questions on one case, a dataset question first, answers final once submitted, then a 60-second recorded recommendation.
Candidates report: Candidates report a calculator is allowed. BCG hasn't published a Casey rule, so follow your invitation.
Example · practice content: Union Commercial Bank is DrillCase's own Casey-style case: an invented bank, written for practice. It is not a BCG case.

Not in this course: The CCA (BCG's other online test), how BCG grades free-text answers (it hasn't said), and your camera setup. Our free Casey guide covers what's known.
