I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (Seattle, WA) in Feb 2012
Interview
My resume was found by recruiter from Seattle that applied on my behalf to Amazon.com. Initially everything went pretty smoothly. First interview was phone interview conducted by non-technical person who had a list of questions and wrote my answers. After that they send me coding assignment that I had to finish in 24 hours. This "skills test" consisted of 8 different assignments that required writing the actual code. Some assignments were small and easy and some pretty big and complicated. All in all it was pretty difficult to finish them in 24 hours especially for working person. After they reviewed code of assignments I have been invited to interview event in Toronto. They just "forgot" to mention that interview will take place at 25th floor and that was deal breaker for me. So as a result I didn't show up for in-person interview and got "no-offer".
Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.
