Yeah, I've interviewed people like this 15 years ago. Degrees and experience mean nothing in this field. The best predictor I found was personal passion projects. Let them get as nerdy as possible, then you will see pretty quickly where their skills are at and what their limits are. And you will immediately filter out people who just studied CS because they heard you can make good money.

Completely agree with this, leetcode has become such a business now of memorization for interviews it’s useless to know if someone memorized a solution or not.

Maybe. There are certainly people in all fields who are book smart and did well in classes but are useless at actually practicing their field (not to mention people who cheated in school and got away with it and aren't even that), and it is worth filtering them out. But I think it is weird that CS expects good workers to have these passion projects. Do we expect civil engineers to build bridges in their back yard on the weekends? Can't someone just be good at their job and have other interests outside it?

I can passionately tell about professional projects.

I agree, however there are so many interviewers who will still treat that as some softball criteria and insist that unless you "prepare" for an interview by memorizing leetcode you are 100% a faker and liar.

Maybe they themselves are fakers and liars / deeply insecure. I got bumped out of an interview rather rudely once because I blanked and couldn’t answer a trivia question about arrays.
