I applied through a recruiter. I interviewed at Amazon in Nov 2012
Interview
Contacted by company recruiter via LinkedIn.
Scheduled for a 1 hour interview. The information was very complete and the schedules were flexible.
The interviewer called on time. Briefly introduced myself and went on to the problem solving. In the end I was allowed to ask him some questions.
The overall process was smooth, except that the interviewer has a strong accent and talked very fast. I had to verify with him 3 times to fully understand the problem. I could hardly pick up what he was saying for the most of the time.
He gave me a problem and I only can come up with a brute-force solution.
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.
