How this case is scored
Every scored run is read on five lines. The case file, the prompt and exhibits together, opens at the top of the room below, and the rubric stays one tap away while you work.
- Structure. The framework you open with and how the run is organized. Strong: Buckets that cover the problem without overlap, stated up front, with a hypothesis the rest of the run tests.
- Math. The setup and accuracy of every calculation in the run. Strong: Clean setup, units carried through, arithmetic that checks, and a stated sanity check on the final figure.
- Data and exhibits. How completely the case file is read and used. Strong: Every exhibit read for what it proves, the decisive figures pulled out, and nothing important left unread.
- Communication. Whether an interviewer can follow the run without effort. Strong: Top down answers, signposted moves, and thinking stated plainly enough that no point has to be asked for twice.
- Recommendation. The close: a decision an executive could act on. Strong: A clear decision, the reasons in order, the risks named, and the next step stated.
