I have passed interviews at Google, Palantir and IMC and in all cases I didn't know any of the questions I was asked

I'm a two time icpc world finalist who considered it borderline cheating to study while I was competing

Which to be fair is probably why we never did well at the actual world finals

But c'mon, you can't figure out how to reverse a linked list from just the problem description?

But okay here's a point on the memorization side: The first words I said at my interview for my current job were "Oh yeah this is Huffman coding I learned it in logic class in 2015"
