Amazon Software Developer Engineer (Internship) interview questions

There were 3 round of online assessment (2 coding for the first round, LP question second round and work simulation the third round). I did farely well on all three rounds of OA, and I received final round screen internview. The interview took way longer than I expected. I was expecting 45min, but it was at least double that time. I solved all the coding question and answer the LP really well, but still got rejected. Overall not a very pleasant experience.
