There were multiple rounds of interviews like aptitude tests, Team discussion, and one on one. Each round is a bit difficult. I successfully passed all the rounds. And there is an HR round as well

We reached to company by 10Am it self but then said 11AM interview will start and they made us sit in a big hall beside company and by the time they start 1st round its 2 to 3pm then 2nd round 4-5pm then by the time they move us to 3rd round its 6-8pm we reached our homes by night 10-11pm, it shows their lack of preparation and there is 3 year bond which is quite extreme
