Applied through the Amazon Careers portal.

Received an Online Assessment (OA) with 3 rounds:

• Coding Challenge
• Work Simulation
• Work Style Surveys

I cleared the round and was invited for the final 4-round Loop interview.

Round 1: Leetcode medium question based on trees.

Round 2: System design question on a specific scenario that the team is currently facing.

Round 3: Leetcode medium question based on a monotonic stack.

Round 4: ML breadth round focused more on basic to advanced ML knowledge and a discussion on how you would approach a given ML problem that they are facing.

All rounds constituted at least two behavioral questions, either at the start or end of the interview.
