3 Round , Leetcode in 2 one was behavioural. Not the hardest if you just do Leet code hard/medium problems. behavioural will be okay if you are able to speak clearly and without difficulty.
I applied online. I interviewed at Amazon (Sunnyvale, CA) in May 2022
Interview
Applied online through the career portal. First step was OA, after that work place assesment and then final round with an engineer, which consisted of LC medium BST and behavioral.
Asked leetcode medium and hard level questions , interview was direct and they looked more for concepts of dsa and fundamentals like os, compiler and also at contest ratings and your projects
