Doesn't impostor syndrome imply mistakenly feeling that they are not qualified to do their work? I think this is different because said people seem to be great engineers and confident at their actual job. What they are not confident is in their ability to be Professional Interviewers/Master Leetcoders, which is a skillset almost completely divorced from their actual work. I just landed a new job at a FAANG-level company two months ago. Not surprisingly, my actual work has no commonality with my Professional Leetcoder skills. I haven't looked at a leetcode problems since I got the offer and I fear my skills have already atrophied.
