If you give live coding tests you're a moron. Here's why. Not all but many of us coders are autistic or highly functional autistic and our brain shuts down in high stress social situations with someone watching over you. Plus whiteboarding when I never fucking whiteboard anything. But get us alone in a room with a task and we'll whip your ass.

My last boss pulled this on me. I almost didn't get the job. Then I told him to assign me any project as homework. Overnight I produced a program that blew them all away. Got hired.
