I think it honestly not even a signal of how good anymore. It's become noise in my experience..

I've worked with an absolute leetcode beast and had a masters in CS. He insisted we use Redis for a project with a lot of relational data. We ended up building a mini relational database on top of redis. Whatever you're imagining about the dev experience, it was worse. He was a lead/senior engineer at the company. Turns out he never bothered to properly learn SQL because he didn't like it. C'est la vie, ggs I guess.

One of the best engineers I worked with was a biochemist who fell in love with programming through chance.

Most of the people I admired in the industry are self taught and passionate about the craft; a lot of them are also immigrants who didn't have access to prestigeus unis. Some went to uni but admit they've been programming since before that.

You can't really learn to be passionate about the craft and to enjoy learning at any uni.
