I applied through an employee referral. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Jan 2014
Interview
Internal referral. Contacted by a recruiter within a few weeks. Was sent a three question coding test, and a week later was asked to fly out for an interview (expenses paid).
Onsite interview consisted of the standard questions, with four 45 minute interviews. Interviewers were all software engineers and asked the standard breadth of questions (OO Design, Data Structures, DFS/BFS).
Interview questions [1]
Question 1
NDA signed covering questions. They're not unusual though.
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.
