Recently done with my Amazon Interview for New Grad 2020. Was not able to clear the second round.

OA1 : 7 Debugging questions was easy if you are use to coding plus if you are not nervous. I got 5/7 correct and I was not expecting it to clear but I got the email for OA2 in 15 mins.

OA2 : There were two questions:
1. Searching in a 2D matrix
2. Critical connections

I knew the questions the only thing that I lagged was practice. Cracking a new grad role is not that tough if you have enough practice. All the questions are out there obviously they will not come as it is there will be some changes in the code but the crux would be the same. I am confident enough that I will crack it the next time. All the best to all of you. Practice is the key.
