Amazon SDE-intern interview questions

OA after an application. 2 leetcode easy/medium problems, pretty light. Now for the interview. My first one - interviewer never showed up. Had to email them every day for almost 2.5 weeks to even hear back, finally got an update about 3 weeks after. My interview got scheduled 2 days out from when they gave me an update. Interview: Guy was cool, asked me 4 LPs with about 2-3 follow ups each. Then asked implement Trie from leetcode. Pretty bad experience, pretty standard Amazon mess ups

First round is an OA with two medium leet codes. Second part was with an amazonian and it went smooth. They asked behavior questions first 15 min, and the rest of the interview was technical, they asked me one medium LC
