J'ai postulé via un recruteur. Le processus a pris 2 semaines. J'ai passé un entretien chez Amazon (Seattle, WA) en sept. 2011
Entretien
I was contacted by an Amazon recruiter for a position that would involving refactoring existing code from C/C++ to Java and other technologies for internal use as well as tools for customer (seller) use. The technical interview was challenging but nothing a competent software engineer shouldn't be at least familiar with. Big O notation, data structures (specifically trees, binary trees, and tree searching algorithms) are a must to confidently proceed.

Question 1
Given a set of unique integers except one, that has at least a duplicate, create a function to identify which integer has the duplicate entry
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.
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.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.

Question 1
Questions were mainly hashmap, sliding window and interval related.
