Yes, tech hiring is entirely broken. I’ve had so many interviews and have been turned down a lot. It sucks but you can’t take it personal. You have to realize interviewers are dealing with time shortages, incomplete information and therefore looking for cues you’re a good fit. Most of those boil down to personality.
Whenever I start interviewing, it takes a few fails before I finally realize: my talents are not (at all) what interviewers care about. Talent is just the icing on the cake. Once I remember that, I focus on being personable and start getting multiple offers. It’s always been like that.
