I applied through college or university. The process took 2 days. I interviewed at Amazon in Oct 2013
Interview
On-campus interview. I had a 45-minute initial interview that covered high-level web-systems architecture questions, where we talked it out and drew some diagrams. No coding. Then had a callback for another on-campus interview 2 days later, where each of 3 interviewers started with some personal questions, and then asked very feasible coding questions that I answered on paper. Got an offer later that night.
Interview questions [1]
Question 1
Nothing too crazy, really. Just know straightforward algorithm/coding techniques, and be prepared to work in pen/paper in a language you're comfortable with. They were understanding about not knowing the exact methods for language API calls, etc.
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.
