You're Not Interviewing for the Job. You're Auditioning for the Job Title

Ha. I like to give a systems design scenario that rewards simplicity. Candidates who complexify it (usually in very predictable ways) get rejected. The few who see the simple path have been great hires. Because they also asked the right questions.

Isn't that just another kind of trick question? It seems like that relies a lot on the interviewee guessing that you aren't looking for a standard complex solution.
