I know this is a basic question that has probably been asked before, but exactly how important is interview performance in determining the rank position of a residency applicant? Suppose applicant A has excellent grades and board scores, but seems aloof or awkward on interview day, whereas applicant B (who only gets an interview when a spot opens up after a stronger applicant cancels) has mediocre grades and board scores, but comes across well on interview day. Who would probably end up being ranked higher - applicant A or applicant B?
