Online Assessment: There was an online coding assessment in which you have to solve two coding questions in 70 min followed by behavioral pattern questions separately. Both coding questions were medium level and I was able to solve both of them. After one week of this round, I got a selection mail from their recruitment team for the next rounds. All the interviews were conducted on the Amazon Chime platform.
Technical Round 1: The interviewer was SDE – 2 at Amazon. He started with a quick introduction. After that, we moved to coding questions. He pasted a question on the live code link text editor and also explained that to me. I was asked to explain the optimized approach, write code for it and tell about space and time complexity. After that asked questions on leadership principles.

- https://www.geeksforgeeks.org/unique-paths-in-a-grid-with-obstacles/amp/, somewhat similar to this, but a harder version.
I was able to solve both questions in the given time and with an optimized approach.
Technical Round 2: The interviewer was an SDE – 2 at Amazon. He first asked for an introduction followed by questions on leadership principles. He then moved to coding questions:
- Clone a singly linked list using two pointers.

I was able to solve both questions in the given time and with an optimized approach.
Bar-Raiser Round: The interviewer was Software Developer Manager. He asked for an introduction and then jumped into the coding questions:
- https://leetcode.com/problems/edit-distance/
- https://leetcode.com/problems/word-break-ii/
I solved both questions and then he proceeded to questions on leadership principles.
Verdict: Selected.
Tips:
- Please focus on leadership principles. Amazon gives equal weightage to these questions.
- For amazon you should practice some situation-based questions.
