Amazon Software Engineer (internship) interview questions

i was contacted by a recruiter told me that they would set full time interview for me but i was not graduating back then, so then changed it to internship interviews. There should be two 45 minutes phone interviews. But that was a mess, these two were set in two different days and one of the interviewer didn't call! And they set another one, turned out the recruiter mixed time. That was totally a mess. And recruiter didn't contact me for several weeks, when i emailed her asked about how's it going she just replied a rejection letter. Awful experience.

There were two interviews. The process is smooth. The first interviewer called me 10 minutes late. His Indian accent made me barely understand his question. He asked me 2 questions. The first one is about to print a tree level by level and the second one is about basic understanding of OOP. The second interviewer asked questions about Java including sorting and searching.
