Their code is aways terrible, and they constantly think it's good.
The exercise is always the same: explain the math to me, like I'm 5, then we profile it and see what is faster.
Oddly Claude Code, integrated into their IDE's has made this situation happen much less.
I never want to work in a place again where the fun way to start the Monday meeting is a "math problem".
PS: Don't even get me started on their SQL.
It's like "software dude thinks he can do hardware", but on steroids. They don't know what they don't know and they think they have a panacea in their hands.
Don't you know? Software is beneath them and the fiddly bits are just standing in the way of them getting their BigImportantWork™ done.
