The other important advice I give people is to stop taking it personally when you don't get hired. I know that's hard to do. But the hard truth is that interviewing is a dysfunctional game. It has very little correlation with your actual value. Just focus on getting past it.

An addition: as someone who has recently been on both sides of the hiring process: sometimes there are just too many great candidates. It's a good position to be in when you're on the hiring committee, but a lousy position to be in when unemployed. (Most of the people I've lost to, I'd hire too.)

TBH I am pretty zen about failing interviews. Not even getting to the interview bugs me more. And it ain’t easy these days.

The mind game when you think, dang it's been a month and nothing! Then you realize they're short-staffed and just getting around to setting up interviews.
