I do interviews for my team, and I'm very aware that framing questions the wrong way quickly leads people into the trappings of their own obsessions. Be that a need for optimising the wrong things (e.g. optimising minute but easy to optimise logic next to large, network-heavy calls), or assuming the wrong perspective on a task (e.g. getting tasked with an accidentally math-heavy problem, and assuming it's about solving the math instead of their overall approach to new requirements) or simply lacking the confidence to question obvious problems in the task they were given. Interviewing is a stressful to downright dehumanising process that is hard to get right, even with years of experience.
