How we review all 212 interview questions before they ship

A bad interview question is worse than no question — it teaches a wrong mental model with false confidence. Our first batch of 40 draft questions got rejected entirely because they tested trivia, not understanding.

The three-stage review

Every question is written by an engineer who has actually been asked it in a real interview, reviewed by a second engineer for technical accuracy, and then user-tested with five learners to confirm the explanation actually teaches the concept rather than just stating the answer.
