See placements are the least thing you have to worry about when you go to Insti’s like BITS, IIT.
The things you have to worry about before joining the colleges is — will the institution provide me with opportunities to attain my full potential,
If the institution is capable of providing you the opportunities(good companies) then you have to worry about is — what should I do to reach my full potential. (how much work should I do to get so and so package)
Bottom line : There will be good companies (each and every branch)visiting BITS, it is you who have to prove them why they have to pay you large sum.
