A year ago I wrote a (shorter) post on the same topic: https://smarketshq.com/notes-on-interviewing-engineers-a4fa4383968a https://smarketshq.com/notes-on-interviewing-engineers-a4fa4... A reasonable question should never require the candidate to know "just a single trick". Questions that require to combine approaches are far better - they can actually measure if the interviewee can reason about the problem and identify the points for trade-offs. Btw: if you're interviewing more senior candidates, a code review question is often a good idea. It turns the situation around, from "how do you build this?" to "how would you fix this?"
