Sensiple Software Developer interview questions

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
