See, IIIT Hyderabad and NIT Calicut  the both are the top and renowned institution in the whole India. But according to my assumption, IIIT Hyderabad is slightly better than NIT Calicut in case of its magnificent placement wing.

Basically both the institutions have amazing placement record in last few years and the most important thing is many genuinely eminent and highly-esteemed companies come to both college campuses as mass recruiters. Ok I'm providing the placement details of both the instituions very shortly in this regard:
