Amazon SDE - 1 interview questions

The interview was an oncampus Interview process. I have got this opportunity from campus placement interview. I made it upto the 2nd round. The interview process was very smooth and the interviewer was very friendly.

The interviewer was nice and asked few questions on binary trees and linked lists. They helped throughout the process regarding any hints etc. It was moderate. The only thing that I felt was extremely unfair was how long they took to get back with the candidates regarding the further process. It was over a week. Very unfortunate that they would put candidates through.
