Amazon Software Developer interview questions

I got this opportunity by submitting my resume on the career website of Amazon through the graduate entrance. After two weeks, I got email for the phone interview. They asked me for giving several available dates for the interview. The interview process is good and the interviewer is very patient. The questions are basic algorithm questions, but you need to calm down. I was nervous and made some mistakes. But that is OK, because they also care about you ability to think and finding errors. So the recommendation is trying to provide more ideas in the interview process not just using one method to solve the problem.
