Amazon Web Developer Engineer interview questions

Got call from an in house recruiter and started the scheduling for over the phone technical interviews. Had 2 phone interviews (skipped the 3rd), invited to go onsite. Onsite I did 6 face to face interviews with different people. Once back home, 2 more phone interviews followed.

I was contacted by the recruiter without applying in late December of 2012. I had three phone interviews with one person each time, and each interview used CollabNet to do online coding. I felt the the phone interviews were fairly simple, and there was nothing too tricky. The interviewers were all friendly and casual, and I never felt they were trying to trip me up. The phone interviewing process up until the onsite request took about a month. The onsite interviewing definitely had a tougher feel to them, but I probably could have prepared with their interview prep document better. I met with about five people separately including one over lunch in the cafeteria. While none of them were unfriendly, none of them were overly friendly. They were all business with not much room for casual conversations, but that probably helped with staying on schedule. Still, I had the feeling working with them would be all business as well. But even so, they were open to mistakes as long as I talked through my thought process, and they were patient. The office was great looking, and the views were gorgeous, but I noticed the interviewers that brought their laptops with them had old looking PC machines. I guess there's no pampering of developers in that area. It took two weeks to hear back that I was not going to get an offer. The recruiter called and handled it well, but I feel two weeks was a long time to wait for a no.
