They will first take PI, then one assignment, then technical round, then again technical round with CTO. I will tell my experience: Unprofessional people, they have wasted my whole month in interview process saying we will send you offer letter,you r select, we are in talk with CTO. Whats the result of whole this month,now they can't afford 50% hike. Please don't waste anyone's time, time is valuable for every one and everyone put their 100 efforts.

They give you an assignment on completion on which they take an exhaustive technical round. Even after successfully completing the assignments they doubt your skills and consume a lot of time for the process. They keep you waiting for long and do not respect your time and do not bother to call back if the answer is no even after taking so much of your time .
