I applied online. The process took 2 days. I interviewed at Amazon (Chennai) in Aug 2011
Interview
I applied online and after 2 weeks of my application, got an email about the interview and they wanted me to come into their office on Monday morning. I really did not have much time to brush up my skills but presented myself well on the day of the interview with few other candidates waiting for the same position as me. After a brief communication with few of their staffs, they wanted me to come back the next day for skill check interview. The next day morning, I was in their office and two men dressed up real well were questioning me about my education, skills and asked me a few questions about C++ and python commands. I hesitated a bit in the beginning, later on got the hang of it and started giving out the right answers. I thought the interview went on well, at the end they told me they will call me back. I did not hear anything back from them yet.
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.

Questions were mainly hashmap, sliding window and interval related.
