How case interviews actually work
Twelve guides on the parts of a case interview that decide the outcome: how the scorecard is filled in, how to structure a problem you have never seen, the arithmetic that keeps coming up, and the habits that quietly cost points. Written by the two of us, who used to run these interviews.
