I applied through a recruiter. The process took 1 week. I interviewed at Amazon (San Francisco, CA) in Nov 2012
Interview
The hiring process is extremely quick. I had a phone interview with HR, another phone interview the next day with a dev, and flew out the next Friday for an on-site. The entire process was very professional, and I was delighted that at the end I hadn't spoken to a single person with terrible English speaking skills (as is common in the industry).
The interviews are *extremely* easy for a top-tier tech company. Sadly I think they're far too easy, and a lot of not-so-good engineers get through.
Interview questions [1]
Question 1
The "most difficult" question I had was finding the intersection of two arrays. Seriously. The rest were even easier. I'm not kidding.
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.
