I applied through a recruiter. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Nov 2011
Interview
A recruiter contacted me via email.
I chose a day where I could fly to Seattle and attend a day long interview process (There were 4 interviews, each 45 minutes long).
Before the interviews started, we had an informal lunch with some of their employees.
All of the interviewers were nice except one. The interviewer (some manager - which is even more shocking) then became so unprofessional to the point that I felt like yelling at him and leaving the room. Thankfully, there was at least one professional in the room (i.e. me) and I kept working at the problem till he finally got out.
Was given a set of fields. Was asked to figure out the best data structure to store this data in the form of a list and at any given point, retrieve the first 5 (decreasing order) of field values.
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.
The phone screen went longer than expected, focusing heavily on implementation details. The interviewer really grilled me on my approach to a Least Recently Used (LRU) cache, asking how I'd combine a hashmap with a doubly linked list. I felt well-prepared since I had gone through system design examples on PracHub, which made me comfortable discussing eviction policies. The later rounds included more technical questions and behavioral interviews, but in the end, I received an offer, though I ultimately decided to decline. Overall, I’d say the process was average, with solid questions.
Interview questions [1]
Question 1
Design and implement a Least Recently Used (LRU) cache supporting get(key) and put(key, value) in O(1) average time. Walk through combining a hashmap with a doubly linked list, eviction policy when capacity is exceeded, and how you'd extend it to handle thread-safe concurrent access.
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.

Question 1
Questions were mainly hashmap, sliding window and interval related.
