They simply waste your energy and time I attended 2 rounds, till didn't got any feedback. They were ghosted me after 2 nd round. Dude, have some discipline , atleast give a feedback . If you rejecting a candidate that's fine but give proper feedback

It was good interview process and good experience peoples. mostly if your good in technical knowledge you'll succeed this interview process for sure. Hiring process and introducing with team and internal process also good
