Earlier quoted context omitted.
From screenshots ? There's no way that Musk has any ability to judge the quality of a programmer based on "up to 10" screenshots of code entirely divorced from its context, especially since he is not a programmer and has no experience whatsoever with any of Twitter's codebases.
It’s probably more of a filter to see who can’t even come up with 10 examples of work they’ve delivered over the course of a year. I do a lot of code reviews, and it’s very obvious who on the team barely churns out useful code —- even just from the low density and volume of their code.
I’m guessing the screenshots themselves will be less relevant than their owners’ description of what the depicted code actually does.
This is all very dumb and I’m not defending the way he’s doing this.
