I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (Seattle, WA) in Mar 2012
Interview
2 rounds of phone screens (mostly technical questions). Then onsite with 5 45-minute sessions. Each session is one on one (or with shadow), mostly doing whiteboard coding. One of them should be "bar-raiser" interview, but I can hardly tell which one it is. Lunch discussion does not talk about technical stuff, but can still be a hiring manager interview (mostly behavioral questions). Recruiter coordinated everything, can be slow and I had to probe them for status update.
Interview questions [1]
Question 1
Some technical problems and some behavioral questions - mostly probing your way of working and cultural fit
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.
