Hii Melvin

Here are some top colleges i would suggest you

BIT Ranchi

NSIT, New Delhi

College of Engineering, Pune

Lovely professional university

Jamia Millia Islamia, Delhi

If you are so much concerned about only placements, then your college gives very less knowledge to you.  All you need to do is learn as many courses as possible speak to your seniors. Do good internships related to your passion. Hope this helps you. All the best.
