Online Assessment (90 mins + 20 mins)
I was given a test link and a week's time
Online Assessment was pretty straightforward. Both of them were LC medium and I finished the test pretty quickly.
90 mins to solve the below two questions and then 20 mins to describe the approach and time & space complexity.

Virtual Onsite HLD Round (50 mins + 10 mins)
Design HLD for BookMyShow.
I was not very well prepared for HLD and the interviewer asked me a lot of in-depth questions related to indexes and overall workflow for the application, security, analytics, whether to use SQL or NoSQL and why etc...
In the end he asked me few LP questions.
Virtual Onsite LLD Round (20 mins + 35 mins + 5 mins)
Design LLD for Library Management System
First 20 mins were LP questions and then I was asked to create UML diagram on how I will write the classes etc..
It went okay in my opion.
I was asked to join on amazon chime and turn on my video and share my screen for all of the virtual onsite interviews.
I did ask for the detailed feedback to the HR. After a week I got a generic rejected mail.
