There are other good colkeges as well except NITs.
You can alternatively get colleges like Thapar University, UPES dehradun, Manipal University,  CGC Chandigarh, which are Tier Two colleges with excellent Placements and Internship Opportunities with very good brand value amongst recruiters.

UPES has been amongst best for Oil and Gas Engineering, Manipal Has been really good for Computer science, and Thapar is well known brand for Core engineering specialization.

Hope it solves your problem..!!!
All the best.
