Also I doubt that every interviewer making a leetcode interview would necessarily pass it themselves. If you are the interviewer, you can choose the problem, learn the solution, and then profit from the dominant position during the interview.

I have seen colleagues do exactly that: I am fairly sure they would never pass a leetcode interview themselves, and they were not really good coders. But for some reason they really liked making candidates struggle with the one exercise they had learnt by heart.

I have been interviewed (and failed) by people I wish I could have interviewed myself right after. They were very clearly keeping the interview in their comfort zone while feeling superior and making me miserable. I am absolutely convinced that if I had had the chance to invert the roles right at the end and interview them myself, I could have made them miserable just the same.

When you are the interviewer, never forget that you are in a dominant position.
