Amazon Graduate Engineer interview questions

I had a phone screen interview with one of their senior software engineers. The interview process was great. I guess it depends on the person you get. It was my first interview, so I did not know what to expect, but the person was patient with me. With that experience, I now know how to handle future interviews.

As I was being referred by a friend, I got the OA email the next day. I was able to complete the 2 tasks (1 super easy and another one medium-hard), although it took me many tries and I was not able to do all tests (it was recursive, so some inputs exceeded the max allowed memory). I also did the working simulation (getting emails and choosing options) and the personality test (2 statements, which one you agree most). I got the rejection 3 days later.
