About the BCG Casey chatbot case
Casey is a chatbot, not a person. Questions arrive in a chat thread and you answer in writing or by picking an option.
On DrillCaseEvery DrillCase case runs in the same chat layout, so the format is familiar before test day.
Exhibits sit beside the conversation and the clock keeps running while you read them.
On DrillCaseExhibits open in a side panel next to the chat, with a visible countdown.
There is no interviewer to nudge you when your structure drifts.
On DrillCaseEach case is scored when you finish, with a per-question breakdown to review.
