As companies ask 'Leetcode easy' questions, there came to be thousands of online blogs, youtube channels etc.. which trained even the n00bs who can't write good code otherwise. If they train very well they can solve 2sum or write binary tree level order traversal without understanding much. Of course not all interviews can use novel exclusive questions, and these have a non-negligible chance of passing.
Now if you are hiring, you would think, "If these n00bs can solve Leetcode easy with practice, the good ones are solving Leetcode medium with same level of practice. So let's raise the level of questions so that we don't end up hiring these rote-learning noobs". And it continues.
I don't think there's an obvious solution to this, if you don't want to lose the statistically good heuristic of problem solving skills, in order to weed out candidates.
I haven't actually seen that cycle in practice when I've been hiring. Maybe a small number of people practice a lot on leetcode, but it seems most don't. And I think it's hard to get better at those sorts of problems and not get even a bit better at programming in general. Remember the problem here is people who can't code their way out of a paper bag, not people who just struggle with exotic algorithms questions.
