Something neglected in this discussion is the role of hostile interactions from others in this field. Impostor syndrome is not always something with a strictly internal origin. If people are dominating you and making you feel bad, and you become submissive, that is a pattern as old as primates and it shouldn't surprise us when it happens also when you are working with people who are extremely concerned with proving they or their clique are better than others. Which is super common in CS and a large part of why many women have a bad experience.
