What is eligibility criteria? What is ILS (Institute level seat)?

There is no criteria as such. It is a profile based selection. Entrance scores have a 50% marks weightage, Work experience 5%, past academics 15%, GA 15% and PI 15%. ILS are institute level seats for which one can apply, once the ILS notification is out. You will then be called for an interview base

There are specific number of seats allotted for Institute itself which institute fills up on their own. Usually the cut off for ILS seats is almost same as cap round cut off. Last year it was 98.88.
