I applied online. I interviewed at Amazon (Bengaluru) in Nov 2021
Interview
Online test, followed by virtual onsite interview. One Leetcode Medium Question. Rather than the actual code, they were mostly interested in how I approach the problem and I had to speak aloud about my thought process in solving the problem.
