I recently interviewed for Amazon India 2022 Graduate. After clearing the OA, I was invited for Virtual Onsite.
Round 1 :
Started with introduction and then the interviewer directly jumped to Coding questions.
First Question : Based on House Rober 3
Second Question: Binary search Question. https://leetcode.com/problems/capacity-to-ship-packages-within-d-days/

I was able to come up with the solution for both the questions, but I took more time for question 1. So I was not asked any LP based question.

Round 2:
Again the round started with the introduction of both of us. Resume and projects discussion for about 15 minutes and about 5-10 minutes on some LP based questions.
Question 1- Postorder tree traversal without recursion.
Question 2 - N closest points to origin.
I explained and coded both the solution but solution for question 1 is tricky and not intuitive. I was missing one small part in that solution but at last I wrote the correct working code.

Round 3:
With the SDM . About 30 minutes on LP's and Resume based Questions. Then i was asked a question which i did not find anywhere. The question involved matrix traversing in zig zag format, this was not the only part but the traversal had various conditions.
I coded the solution with some if-else and dry ran the code. I was thinking for the optimized version but i was not able to come up with the solution. Interviewer said ok with the solution but asked for something more efficient.
The time was up. So he winded up with the interview.
Result: Rejected
