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.
I applied online. The process took 4 weeks. I interviewed at Amazon (Dublin, Dublin) in Aug 2024
Interview
I have been sent an interview coding challenge. It was a Hackerrank challenge and I completed it fully, tests were passing and all checks were fully done. I submitted the challenge and then waited for a response after sending a submission email.
1 week passed and I sent another reminder email looking for a response back. And then 1 more week passed with another reminder email. I didn't want to be seen as unresponsive so I followed it up. However the person who was responsible for my interview, never ever returned back to any of my emails. I'm assuming what I received was just a simple automatic email including all the instructions for my challenge. I asked a question, sent multiple emails for the results. Nothing!
And then I found out 2 weeks later that I got rejected for some unknown reason. There's no explanation, nothing, no response email. I even doubt they found time to look if I completed the challenge at all. What a poor process.
Interview questions [2]
Question 1
Finding out some suspicious transactions in a list of transactions
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.
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.
