Hello Aspirant,
See placement totally depend upon your skills because any company will hire you and pay you as per your skills, no brand tag of IIT will work there. Yes name of IITs will help you to make your reach to different MNCs with very ease but that doesn't guarantee your placement.
Let me make you more clear with an example,
There are two students A and B, A is from top IIT but no skill which are required for Job, and on the other hand B is from tier 3 college and have sufficient amount of skills which are required by different companies then obviously the demand of B will be much greater as compare to that of B and even B will not have any demand as he doesn't possess any quality or skill to get hired in any company.
So focus on developing your skills, network while you are in your college, no matter in which college you are. Also note that college will also not help you until and unless you work for yourself.
I hope this information helps you.
Good Luck!!
