Amazon Software Development Engineer interview questions

I applied via company site. The process and instruction was very clear. Two parts of online assessments (quizzes and coding problems) and then final virtual interview which consists of 3 interview of 50 minutes each. I did not get an offer and no feedback was given (I was a bit nervous and did not prepare enough).

Interview process is bad. HR and Recruiters are not professional. The feedback is not in time. I didn't get any good experience from Amazon. But the interview questions are too easy. It's easy to get the offer.
