The first round was basic aptitude and essay writing the level of difficulty is average and this is also elimination round.
The second was pseudo coding round It has mcq based programing question like arrays, looping and some data structure question.
Depending on the score in coding round they split us into two groups infra and non infra. Infra for cloud and infrastructure related roles and non-infra for programming related role.
The third round was technical Hr. The level of the interview is average he asked basic questions in c and java like inheritance, Polymorphism, encapsulates etc.. and some final project related questions.

I cleared the interview and got my LOI after 2 months.

Clearing ADAPT is not mandatory but you need to participate.
Due to pandemic I got the offer letter on Feb 2021 and now I have completed my training and looking for project.
