I applied through a recruiter. The process took 3 weeks. I interviewed at Amazon (Seattle, WA) in Oct 2014
Interview
The recruiter contacted me because I had applied internship before. Then I got a coding challenge, including two coding questions and 25 logical questions. After one week, the recruiter notified me to schedule an on-site interview. The on-site interview includes four rounds, and 45 min for each. All interviewers are really nice.
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.
