Recruiter screen, followed by an online coding assessment and then a technical phone interview. The final round was a virtual onsite loop with multiple interviews covering data structures, system design, debugging, and Amazon Leadership Principles. The technical questions were practical but time-constrained, and the behavioural questions required specific examples using the STAR format.
Interview questions [1]
Question 1
Design a scalable URL shortening service and explain how you would handle high read traffic, collisions, database schema, expiration, and basic monitoring.
I applied through an employee referral. The process took 6 weeks. I interviewed at Amazon in Aug 2016
Interview
I was contacted by an recruiter. She sent over a link for an online technical round. This had 4 questions, 1 coding and 3 theory questions (time complexity)related to the coding questions.
I was invited for an onsite interview. The interviewer's were friendly. Asked me standard questions similar to the ones you see in CTCI. There were 5 interviews, and I did well in 4 of them. I couldn't get the solution in one interview. The interviewer was giving me hints but I couldn't figure out the answer.
Overall it was a positive experience.
That moment when the interviewer asked about finding indices in an array for a target sum was wild — I had just tackled something identical while prepping on PracHub. The interview included a technical round with another question about designing an in-memory LRU cache and a behavioral question about meeting tight deadlines. After a smooth discussion, I was told I'd received an offer, which I happily accepted. Overall, the process felt pretty straightforward and not overly challenging.

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.
