The Amazon interview process usually starts with an online assessment that has coding and some behavioral questions. If you pass that, you move on to technical interviews where you solve data structures and algorithm problems and explain your thinking. The final stage is a set of interviews that include more coding, some system design, and behavioral questions focused on Amazon’s Leadership Principles. Overall, they’re looking at how well you solve problems, communicate, and make decisions as an engineer.

The interview process began with an online assessment that included two challenging algorithmic questions to be solved within 70 minutes. The problems required strong knowledge of sliding windows, greedy strategies, and binary search techniques. The difficulty level was noticeably high compared to typical LeetCode mediums. The assessment focused on problem-solving speed, clean coding, and handling edge cases efficiently.

Amazon Online Assessment – Minimum Cost to Clear Binary Array
You are given a binary array of length n.
You may repeatedly choose any window of size k.
During each operation:
Delete (turn into 0) all the 1s inside that window.
Cost = number of 1s in that window before deletion.
Find the minimum total cost to make the whole array zero.
Only got to the 1st round. I got a lonk to a hackerrank problem and had a couple of days to take it. You get 45 or 60 minutes (can't remember) to solve the problem.
