The only thing doing tech tests has taught me is that I'm too stupid to do the job I've been doing professionally for the better part of 2 decades.

Can't just be me, can it? Currently 0 for 3 on interviews because I can't seem to get past the technical interview/test. Usually because of some crazy complicated algorithm question that's never been relevant to anything I've ever had to do on the job in all my years coding.

Also, while I'm ranting: screw the usual non-answer when given feedback.
