But people are taught the basic boring skills required to deliver value in a big org in the first few months and very few fail to learn them in that time, they are by far the easiest skills to teach in software development so it doesn't make much sense to test it when hiring.

Correct. And as far as I can tell, devops folks don’t do leetcode interviews. Most SREs don’t either.

At my last interview process (in June) I was being hired into a more seasoned role where experience matters more than code chops. There was an algorithms question but the biggest weight was put on the “Can you design a distributed microservice infrastructure with good tradeoffs and solid relational modeling”

Series A company so it’s conceivable that I’ll be involved in all parts of the stack.

If I just did well on algorithms (I didn’t) and nothing else, it would be a hard no hire. But they were very impressed when I said “Eh for this load, you don’t need horizontal scaling except for redundancy”
