"Leetcode screens are a matter of grinding for a couple of weeks"

Did you have formal compsci training before you started studying for leetcode? Did you study algorithms before that?

Just wondering how hard it would be for someone who never got a compsci degree and knows nothing about algorithms.

Yes but it doesn't matter, it's a skill you gain and lose with repetition. I have seen many people without formal compsci training pick it up quickly

This may be true for most "Leetcode Easy" questions, but in my experience, Medium and Hard ones require familiarity with graph traversal, sorting algorithms, dynamic programming, etc. In other words: dedicated study.
