I applied online. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Jun 2009
Interview
Two phone interviews and a 6 hour in person 1:1 interview. First two phone interviews cover data structures and basic java concepts. 1:1 interview test on core CS data structures, hash maps, trees, etc, and algorithms. Looking to see how well you can handle large datasets. 1:1 interviews are tough and take up most of the day.
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.
