Ho sostenuto un colloquio presso Amazon nel mese di gen 2014
Colloquio
First,they asked my about my preferred language then i was asked all the technical question and in later they asked me more about the projects I have done. Then at the end they asked me whether I had any question for them. The question was like :
1)what is a BST? given an example then was asked is this a BSt?
2) write the code for find whether the tree is BST or not?
3)time complexity of your algorithm
4)write your atoi function with two parameter as base and number.

All the question were basic coding question. They asked me to the implete a simpler version of a mine sweeper game.
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.

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.

Questions were mainly hashmap, sliding window and interval related.
Interview by recuriter, Phone interview over Chime with one easy Leet code problem and 2 behavioral questions. Although the interviewer was very casual at the start of the conversation, it quickly changed into behavioral questions at the start.
