I applied through an employee referral. I interviewed at Amazon (Pekín, Pekín)
Interview
In the first round, the entire interview lasted for 1.5 hours. It started with a 1-hour system design session, followed by a 30-minute LP (Leadership Principles) discussion, and then one algorithm question.
In the second round, which lasted for 1 hour, the interview focused on system design and LP.
Interview questions [1]
Question 1
System design: Designing the Domino's Pizza System
Coding: Sum of Three Numbers
LP:
1. What is the most fulfilling achievement in your work, and why?
2. How do you handle a situation where there isn’t enough time to complete a task?
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.
