I applied through college or university. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in May 2013
Interview
Made it to the 3rd round interview. First round was a basic HR interview where they inquired about my goals and aspirations. The second round involved actual technical questions, but not too hard. The third round became a lot harder, with questions related more to theoretical concepts. I knew a lot of what they asked but missed out on the more important things they were looking for. Oh and there was an IQ test which was easy.

Question 1
If I give you an array of N integers, find the largest three numbers which will result in the largest product.
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.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
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.
