I applied through an employee referral. The process took 2 weeks. I interviewed at Amazon in Feb 2011
Interview
My friend helped me submitted my resume, and then I got a call from a recruiter in three days. The recruiter helped me schedule my first round phone interview. My interviewer was a software engineer. In the beginning of the interview, he asked some general questions about my current projects and then moved to technical questions. He asked me to implement a function to print out all the permutations of an input string. I completed it and time was up. In one more week, I got an second round phone interview which is scheduled in next week.

Question 1
Implement a function to print out all the permutations of an input 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.
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.
