I applied online. The process took 2 months. I interviewed at Amazon (Toronto, ON) in Apr 2024
Interview
Good, long but straightforward. Multiple stages, you can prepare for this online and from other sources. They are on time and very understanding. Know your design patterns and algorithms, and know how to communicate to amazons standards.
Interview questions [1]
Question 1
"Given an array of integers, return the indices of the two numbers that add up to a specific target."
For example, given nums = [2, 7, 11, 15] and target = 9, since nums[0] + nums[1] = 2 + 7 = 9, return [0, 1].
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.
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.
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.
