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.
