First, I got an OA; after clearing that I had a technical phone interview round with Sr. QA, and they asked a coding question which was similar to this question :
https://leetcode.com/problems/merge-two-sorted-lists/
and then was asked to write test cases for the solution provided.

///Will update this post after my final round.

Update: I cannot disclose the questions that were asked during the interview as I have signed NDA with amazon.

Round 1: Behavioral + coding(You can prepare by solving Easy Leetcode Questions)
Round 2 : questions based on STLC
Round 3 : questions based on STLC
Round 4(with manager): Leadership problems
Round 5 : Leadership problems + STLC
