This is my own experience but I find the evaluation on interest and intellectual curiosity to be more validating long term than being able to rote memorize problems.

Edit: To add some color, I want a candidate who is excited to program, I don’t care as much about their ability beyond having the basics which I find pretty easy to figure out in an initial conversation. Candidates who are excited for the opportunity are generally the ones who I find to excel in the long run.
