I applied online. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Nov 2013
Interview
I applied online last summer and got replied by a recruiter asking me to finish an online assessment. There were three problems. The first one is to check whether the linked-list has a loop. The second one is to find the top five test scores for each student while giving me a list of students and their scores. The last one is also an easy linked list problem.
About one week after the online assessment. I got an onsite interview opportunity in Seattle.
The onsite interview has four rounds and the questions were all coding questions excluding OOD and system design. The team that interviewed me is the kindle team that focused on asking me questions about data structures. I remember the first question was to build a comparator that sorts the given strings. The second is to reverse a listed list. The next interviewer gave me a scheduling problem. I don't remember the details but I used a priority queue to solve it. The last interview question is to give you several points on a 2D plane and find the nearest 500 points near one given point.
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.
