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.
I applied online. The process took 6 months. I interviewed at Amazon (Seattle, WA) in Sept 2013
Interview
I applied online through their website and after about 6 months was contacted and invited to take an online code evaluation. This consisted of 3 coding implementations as well as the Big-O efficiency of each. The evaluation must be completed in 90 minutes. I felt like I did great on these, but a few days later, I received an email that said I did not make it to the next round.
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.
