Amazon Software Engineer interview questions

3 rounds one online coding round one offline interview and one hr round asked various tough questions on dsa all of this is on campus job opportunities. the first round is hard and medium leetcode question . the second roud is more about projects, cmp network, dsa, architecture.

I've been handed off between four different recruiters throughout the process. Was told I passed the interview, but still waiting on offer. System Design round also had no whiteboard/shared coding session, which I found odd.
