I applied through an employee referral. I interviewed at Amazon in Feb 2013
Interview
Had two rounds. First round went fine. Was asked a question I was able to solve. Nothing very tricky, but thorough understanding of data structures and algorithms is a must. The second interview was the worst experience ever. The interviewer's english was quite bad, and at times I wasn't even able to understand what she was saying. and i had to ask her to repeat the question over and over again. And I had the feeling she was typing on the other side, probably getting her work done during the interview. Although I was able to get the solution at the end, finally didnt get an offer. Will never interview again here.

Question 1
Find the longest repeated substring in a given string.
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.
