The Number One Mistake People I Interview Are Making These Days

As a hiring manager, I disagree with this somewhat. Deselecting people based on the fact that they did not send you a thank you email is, imho, quite foolish.

1) It assumes that the hiring manager is holding all the power in the interview process (which is actually not true). As a hiring manager, Ms. Liebman, how many 'thank you' emails have you sent to your interviewees? You think you should not have to? Well, I disagree.

2) It's a nicety, but by no means a necessity. It's a bit old school and in this day and age, with the amount of emails people get, it's not always as welcome as you think.

It falls into the trap of A players hiring A players and not worrying about minutia like this. When B players hire C players, you may get deselected cause you did not stroke their egos.
