Amazon Software Development Engineer interview questions

2-3 telephonic. 3-4 onsite interviews apart from HR round. One of the most fair interviewing processes that I have witnessed.

The first round comprised of an online test which comprised of 20 MCQ's which included questions of both aptitude and computer fundamentals and two questions to code.The next round was an interview round which was approximately of about 45 minutes.Basically,our programming fundamentals were checked.We were given a question and we had to suggest the most optimal solution.
