Amazon Software Development Engineer interview questions

Initially contacted on LinkedIn by a recruiter and asked if I would be interested in interviewing. After a very basic screening call with the recruiter, I was told that I will be contacted shortly about starting the interview process. Within one week I had a technical phone interview where I was asked a single question with multiple parts. The next day, I was emailed about flying to Seattle for in-house interviews. Amazon scheduled and paid for the travel and lodging as well as reimbursed meals and taxi charges while visiting. The in-house interview was a series of 4 one hour interviews, each with a member of a different team. 2 were managers, the other 2 were SD II. Each interview consisted of ~20 minutes of personal interview and the rest was technical. The interviews were in no particular order of difficulty. My third interview was the "bar-raiser". I think the difficulty of the interviews are over-exaggerated online. Just stay calm, be friendly, and take your time. The interview is a piece of cake if you know your stuff and don't panic.

Phone interview with Human resources department. A week later I got an email for technical phone interview. There was online coding question and few oral technical questions. There was couple of behavioral questions also.
