I applied through an employee referral. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Jan 2014
Interview
Internal referral. Contacted by a recruiter within a few weeks. Was sent a three question coding test, and a week later was asked to fly out for an interview (expenses paid).
Onsite interview consisted of the standard questions, with four 45 minute interviews. Interviewers were all software engineers and asked the standard breadth of questions (OO Design, Data Structures, DFS/BFS).
Interview questions [1]
Question 1
NDA signed covering questions. They're not unusual though.
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.
