Went through initial stages of recruitment process for interviews in Sydney. Spoke to HR person for 20 mins on the phone, was then directed to do a technical test.
Test consisted of two simple programming problems with 1/2 hr time limit for each. Would have been easy, except you can't compile run or test your code in the web browser environment for test, unlike just about every other online coding envirnment, eg ideone.com. When I discovered this I frantically tried to get my dev env up and running on my local machine and wasted some time and only had 15 mins left for the second question, which I didn't complete.
Anyway, would have been nice to know more about how the test worked in advance...
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.

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.
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.

Question 1
Questions were mainly hashmap, sliding window and interval related.
