A global bank — $400M annual public-cloud spend, growing 35% year-on-year — has a board mandate to repatriate 40% of workloads to on-prem within three years. The CTO is sceptical. The CFO is enthusiastic. The mandate was sparked by one expensive AI training run that broke through the budget envelope. You are advising the CTO on how to position a counter-proposal that takes the board's concern seriously without committing to an arbitrary 40%.
The full evaluation rubric — including the signals interviewers reward and the red flags that sink candidates — is revealed in your scored report after a live run.
Run this case live: the interviewer pushes back the way a real McKinsey interviewer would, then scores your structure, math and recommendation with a full report.
