BCG Casey is the chatbot-led online case BCG uses in many offices to screen applicants before live interviews. Instead of talking a case through with a consultant, you work through a business problem with a chatbot that asks for calculations, chart reading, choices between options and short written answers, each on its own clock.
This hub gathers our Casey articles. The BCG online case guide is the place to start. The shorter articles take one question type or one decision at a time. Formats differ between offices and change over time, so every article shows when its facts were last checked.
Candidates describe a mix of exhibit reading, arithmetic under time pressure, picking the right data to answer a question, and a short recommendation at the end. Our format breakdown walks through each question type in the order it usually appears.
Not quite. "BCG Online Case" is the general name candidates use, Casey is the current chatbot version, and the Case Completion Assessment (CCA) is an older written format still reported in some processes. The differences matter for how you prepare, and our Casey vs CCA comparison lays them out side by side.
Most points are lost to time rather than to hard ideas. Build speed on consulting maths and chart reading first, then practise full cases with a timer so that the no-going-back rule stops being a surprise.
