Netaji Subhas University of Technology

Assuming you are talking about NIT Delhi, IIIT Delhi, NSUT & DTU. This would be my preference if looking for placements :
1) DTU / NSUT COE (choose whichever is closer to your home)
2) IIIT Delhi CSE
3) NIT Delhi CSE
If interested in research:
1) IIIT Delhi CSE
2) DTU COE
3) NSUT COE
4) NIT Delhi CSE.

I would say both DTU & NSUT are similar. Choose the one which is closer to your home, even though average of DTU COE is slightly better than NSUT as you'd be saving much more time in travelling. Then, I would suggest IIIT Lucknow & then JNU college of engineering.

I studied SE in DTU. The course is very similar to CS & is very much industry relevant. Also, some of the professors are really good. Placements are slightly better than IT even at DTU. While ITNS at NSUT is a new branch. No batch has been placed/graduated yet & you'd be restricted to Network side of it. IT in itself has many courses overlapping with ECE (more than SE & COE). Moreover, I think ITNS is better for those interested in that field. For generic software engineering roles, DTU SE would be a better choice.

Just make a NCL Certificate of it through any court in Delhi.

Wait for Maharashtra all India cap up round.

DTU is good for biotechnology.

DTU biotech is better than NSUT.

Yeah you can get ECE in DTU.

Yes you can get DTU with a lower branch.
