I applied through college or university. The process took 1+ week. I interviewed at Amazon (New York, NY) in Apr 2013
Interview
The recruiter for NY area contacted me and asked me to do a online test before a deadline at first. The technique test is rather easy, whether there is a ring in linkedlist, intersection of two linkedlist, and calculating the score of 5 top most grades for a student. It's not that difficult but the result turned out that i failed the next Friday. Here's a long hogan test afterwards, with duplicated questions.

Question 1
Time is limited, must program & debug within 30 mins/ question
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.
