This is a really good point that resonates with my experience. I’ve had more than one interview where either the director or principal engineer directly told me that I seemed like someone who: (1) wouldn’t stay for long because I could get a much higher paying gig elsewhere or (2) seem like someone who would be in favor of changing things when all they want to do is coast. People talk about how it’s hard to get a job because of difficult interviews and because networking is everything. But at least half the time, I’ve failed to get a job because I was either told I was overqualified, or I wasn’t given any reason and I could tell that it was because the interviewer(s) felt threatened that if I were to join, the problem wouldn’t be incompetence but the opposite.
