Since NDA is signed so cant share the exact question. But will give the rough idea of levels.
Round 1: 1 question -> 20/12/21 (60 mins)
Question 1: Similar to Valid Parentheses but some modification.
Question 2: Heap based LC medium question.
Round 2: 1 Question -> 20/12/21 (60 mins)
Alot of discussion on projects and Leadership principles.
Question: Tree DFS traversal based LC Medium question
Round round 3: SDM round -> 11/1/22 (35 mins)
This round was supposed to happen on the same day as previous round but the interviewer was on leave so it was rescheduled to later. Mostly leadership based round with discussion on projects and question on basics of operating systems and Dbms. Interviewer was not friendly. Looked more like 1-1 manager discussion where whatever I was saying, was taken against me.
Round 4: Bar raiser round -> 11/1/22 (60 mins)
This was the most chill round and discussion was mostly on my projects and leadership based principles. Later he asked a question similar to robot in the maze
Update: Decided not to join Amazon. Joined another startup with slightly higher base
