I applied through college or university. The process took 1+ week. I interviewed at Amazon in Oct 2013
Interview
There were four rounds of interview. cleared first round. basic questions on data structures and algo( binary search, linked lists, BST) The other rounds involved questions on system design. The overall experience was good. The interviews focus more on your analytical and logical thinking and less on your coding skills.
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.
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.
