I agree with this.

I think there are ways to notice this during interviews. I'm a fan of a junior engineer interviewing a candidate for a senior position - as a way to see how well they interact. Perhaps the question could be more open ended (e.g. explain x,y,z concepts - maybe oven ones that the interviewer doesn't know but wants to learn). If the junior feels like they had a good interaction, were able to learn, and felt respected through the process, great. If the candidate seemed offended by the lack of experience of the interviewer, then not great.

A highly subjective signal though.
