Maybe I'm missing something, but why isn't the implication going the other direction?
In my experience, the problem is that interviewers have no idea how to correctly value a candidate's performance. Maybe the candidates are closer to being well-calibrated, but their self-assessments don't match up with the interviewers' because the interviewers don't know how to gauge what they are looking for?
Making the assumption that an interviewer knows how to measure the response of a candidate, even in cases of extremely quantitative questions with well-defined answers, is highly suspect to me. I think virtually no one knows how to do that effectively.
