first had a coding round that tested my problem-solving skills and knowledge of algorithms. After that, I went through three interviews, which were a mix of technical and behavioral questions. Each interviewer focused on different aspects, like system design, data structures, and cultural fit. I had to explain my thought process clearly, solve real-world problems, and demonstrate my understanding of key concepts. The entire experience was challenging yet rewarding, and it gave me valuable insights into Amazon's expectations.

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.

Question 1
Design a scalable URL shortening service and explain how you would handle high read traffic, collisions, database schema, expiration, and basic monitoring.
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.
