The process took 3 weeks. I interviewed at Amazon in May 2011
Interview
One of Amazon recruiter found my resume online and contact me for the openings and set up for the phone interview within a week.
The first phone interview went well. The interviewer is very nice and asked me several technical questions. The whole process lasted about 45 mins. At the end, he asked me to send him the codes of one of interviewed questions to determine.
Couple days later, I received the recuiter email about setting up the 2nd phone interview. The 2nd interviewer seems not have much patience and I was stuck in one of the questions. so it ended quickly.
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.
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.
