I applied online and received an invitation letter for the phone interview. Interviewer asked some basic ML questions and some past research experiences. Reading and getting familiar with Amazon's leadership principles will be super helpful.

It was good. I was asked two questions. 1. Rotting oranges (leetcode) 2. Next greatest element 2 (leetcode) I got confused at why we should go for a max in rotting oranges. The interviewer is very friendly and helpful and she helped me to get to the answer. In the end, I have cleared round 1 but I was not allowed to round 2 because I am a B.Tech. (they wanted Ph.D)
