“The math compounds — I fumbled the break-even on Q3 and by the time I hit Q5 every number I was feeding in was already off. There is no way to go back and fix it.”
BCG's Casey chatbot case is the first-round screening step at most offices. Practice the format below.
Regional note: Germany and the wider DACH region use a separate cognitive / numerical test instead of Casey. London and several Southeast Asia offices deliver the Casey case flow via the HireQuotient platform with added webcam proctoring.

Candidate debriefs
Real BCG Casey is hard to prep for because the debriefs are scattered across prep forums. Here is what candidates actually flagged after sitting it.
“The math compounds — I fumbled the break-even on Q3 and by the time I hit Q5 every number I was feeding in was already off. There is no way to go back and fix it.”
“Honestly, the real case moves faster than any mock I did. Prompts are dense, the math is heavy, and 25 minutes is not enough runway if you have not drilled the format specifically.”
“The 60-second video at the end is the worst part. You prep for a minute, record for a minute, and if you run long the clock just cuts you mid-sentence. No second chances in my version.”
