this is advice i give to a lot of people trying to get into the business or switch jobs. no matter how prepared or qualified you are, every interview is a roll of the dice. maybe the interviewer is in a bad mood. maybe you're in a bad mood. maybe there's a communications barrier. maybe there's some organizational issue (too many candidates in pipeline, re-org, etc.) that causes the bar to temporarily be set extremely high. It's ultimately a numbers game and it doesn't make sense to get too invested in one company or read too much into one result
