Surprisingly, for many of us, it didn’t come down to the candidate’s creative ability or their analytical fluidity. Rather, it frequently came down to whether or not the candidate had a structured way of tackling the problem.

Oftentimes, when I pose a design question, the candidate will panic and will begin rattling off ideas without really breaking down the problem and setting up a framework for thinking about a solution. …
