There were 2 technical phone rounds. Both interviewer were from the same team. They use collabedit for the online sharing of codes. In the first round I was given 2 coding questions. One on arrays and one on graphs. I comfortably coded first question but my second code was not up to the mark though it's logic was right. It seemed like first interview was happy with my performance. Then there was another tech phone interview with different guy who asked me a question on Arrays and strings. I gave him to solutions for the problem but he wanted the improvement. Then after 15-20 min. I got the correct solution and coded it in next 5-7 min. I feel there were couple of bugs in the code and because of the time I took to answer that question, I did not get further round of interview.
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.
