Guy writes like he’s the main character when he’s probably dev #48373 at CrudCorp. I bet the internal company tool he works on is pretty slick though.
Most smart people I know don’t like toy leetcode problems, they like real problems which are orders of magnitude harder and not solvable by LLMs. Leetcode is for people who got good grades and want to feel smart by learning the rote tricks to solve leetcode.
I didn’t do any leetcode, but I did some Project Euler, which was the cooler predecessor. It was a fun, but I don’t know why these gamified programming things have become so predominant in hiring. Why not hire based on Factorio progress or some Zachtronics game score?
