Amazon interview soon, bombed MSFT last week - need prep advice

Hey devs, I’ve got an Amazon interview coming up and really don’t wanna repeat the mess I made at msft last week. Been grinding LC (mostly mediums) — I’m comfortable with trees, DP, linked lists, and arrays (except the LC Hard). Just getting into graphs, stack’s alright, but strings + sliding window still give me headaches, and I’m not too confident with PQ/heap either.

Which DSA topics and LPs should I prioritize, and are there any reliable LLD resources you’d recommend? I’d really value insights from anyone who’s been through the Amazon interview process.
