Your questions are pointless. I have no interest in CS puzzles at all, I don't memorize or practice them, and that's what you're testing for. I write code to build stuff.
Why not have a conversation with them about things they have built instead? Not form questions that say "tell us about a time you encountered a problem you had to solve" but an actual conversation. Like... an interview.
