I applied through college or university. The process took 2 days. I interviewed at Amazon in Oct 2013
Interview
On-campus interview. I had a 45-minute initial interview that covered high-level web-systems architecture questions, where we talked it out and drew some diagrams. No coding. Then had a callback for another on-campus interview 2 days later, where each of 3 interviewers started with some personal questions, and then asked very feasible coding questions that I answered on paper. Got an offer later that night.
Interview questions [1]
Question 1
Nothing too crazy, really. Just know straightforward algorithm/coding techniques, and be prepared to work in pen/paper in a language you're comfortable with. They were understanding about not knowing the exact methods for language API calls, etc.
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.

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.
