I applied through college or university. The process took 1 day. I interviewed at Vignan Schools (Hyderābād) in Jan 2019
Interview
It was a 3 member panel through campus-placement. They had given an initial test which had behavioural questions. I don't think they checked the answers and then went straight for the interview round which was also mostly behavioural questions (and one psychology theory question).
Interview questions [1]
Question 1
What will you do if there is still work to do but it's 5pm and time to leave?
