I applied online. The process took 2 weeks. I interviewed at Amazon (Seattle, WA) in Aug 2012
Interview
Had 2 phone interviews. For the first interview I got some common questions and then a technical question: print all permutations of a string. The interviewer was nice and patient, giving hints along way. The phone conversation ends after 1 hour but I continue to work on that and send him my complete answer later. The second interview consists many technical questions and I did not so good.
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.
