Amazon Software Engineer I interview questions

1st round was not too tough . general technical questions about networking , data structure. Second phone round was drilling

I had interview last week, and the interviewer ask me a lot of questions. First he asks me a lot about my project, and how I solve some specific problems. Following are some questions I can remember. 1, what is IPC 2, how to control access on shared memory 3, what is composite design pattern 4, how you arrange your time before deadline coming 5, find number happen even times in an array all numbers happen odd times. 6, what is hashtable 7, in stl, what is hashtable 8, how to deal with deadlock. 9, ask him some questions 10, what are encapsulate, polymorphism, inherentence. In this interview, I give all the answers, but maybe not very concise. I think that is the main problem I have been denied. If anyone knows how long I can apply amazon after this?
