Even just giving Leetcode questions isn’t enough anymore… I’ve had plenty of people just memorize the top 50 used questions and be able to answer them, but then not be able to explain anything about their answer. It’s exhausting.

Explaining the reasoning while solving the code puzzle is the most important part, though. Just being able to solve them without speaking a word has never been enough. Unless you are talking about automated coding tests (but that also has never been enough).

It's super easy to filter for that though. Just change the problem slightly. If they give the rote answer you know what you need to know. It does require that you know the answer though. :)
