I applied through an employee referral. The process took 3 weeks. I interviewed at Amazon (Dublin, Dublin) in Dec 2010
Interview
Had 3 phone screenings,
process took some time due to my personal activities and business, everyone from amazon was quite nice and helpful, there was no problem to reschedule date/time with HR
questions were challenging but expectable, you need to know a lot from various areas like
java
networking
databases
algorithms
oo design
Interview questions [5]
Question 1
what is TCP/IP?
differences between TCP UDP?
describe TCP IP model.
You have dictionary. How would you design function/system that should return true/false for check if a word is in a database? How would you scale your solution if word db does not fit in memory/disk? How would you scale it to really big db of words that should be located on n computers?
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.
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.
