Amazon Software Development Engineer II interview questions

A nightmare. I got contacted by HR for an opportunity at Amazon, I was given an online assessment, which needed to be completed in the next 2 days. Which I did. I got a call that I cleared the Online Assessment. I will get a call for a face to face interview. After waiting 2 months, I did not receive any communication. I mailed HR asking what happened (this is not the first time when I was ghosted by HR telling you have cleared the assessment and you will get a call). They responded after a while that they will schedule in next one month. Interviews were scheduled and I completed 3 rounds of interviews namely LLD, Coding, HLD. I was comfortable that I did well. But again for the next 2 weeks no communication from HR. Suddenly got a call after 2 weeks and they are scheduling the bar raiser tomorrow, Be ready for an interview. Okay I followed. Completed the bar Raiser round that went well too. 3 weeks passed, no communication, I pinged HR what happened again, they said you will have feedback by tomorrow. Then 2 more weeks passed. No communication. I just want to ask one thing to HR and Amazon: Respect the time of other people, and have a bit of responsibility. Teach the same Leadership principles to HR which Amazon brags about in the interviews. I have no problem with the panel. Very knowledgeable people had a great experience during the conversations with them.

First round: phone screening (25 min LP, 30 min code exercise, 5 min "do you have questions for me ?") Second round: virtual onsite, 5 one-hour interviews with 1 hour break after the 3rd interview. They are the same structure as the phone screening except the interview with PR. PR didn't do code exercise with me
