Amazon Software Engineer Internship interview questions

I first postulated online, got some online test to do. Once I did it, I received another one more technical one to do (I believe I passed them quite well since they were automated and I quickly passed all tests). Then got a message that I would receive a message about any next step. Never received any message later on (6 months later, so I guess I won't from now on). I tried to contact them to ask about the state of my postulation. No answer... Well I guess it's a big "We don't care about you, we have enough people to select from" or whatever.

The process itself did not take long at all. The interviewer asked some basic behavioral questions. The technical question was also fairly simple and I answered it correctly in the given time frame. However, I was rejected the day after without a reason. The interviewer seemed satisfied with my answer, although he was a bit condescending when he did not understand what I was doing.
