What is the current actual condition of NIT Delhi? Is it good or not? If I choose NIT Delhi over IIITD and NSIT/DTU, will it be worthwhile for me or not?

No, it’s not wise to choose NIT Delhi over prestigious Delhi colleges like NSIT, DTU, and IIIT Delhi. Your first preference should be NSIT or DTU followed by IIIT Delhi. So, NIT Delhi should be your last preference among these colleges. 

NSIT/DTU are well-established institutes while NIT Delhi and IIITD are still in their infancy stage. However, because of their central location, all these 4 colleges have a decent placement scenario. Most IT companies from Gurugram, Noida, and Delhi visit all of these campuses. NT Delhi operates from a temporary campus N.I.L.E.R.D. located in a remote place, Narela. Most faculty lack experience and won’t be of much help in projects. 

The hostel and classroom facilities however are pretty good and a 24/7 Internet facility is provided to the students. The college is remotely located so it will be difficult to find eateries serving decent quality food. Being new, the campus has an active club culture and lab facilities. 

Overall, I feel NIT Delhi fails to offer the exposure and opportunities that other Delhi engineering colleges offer so should be your last choice.
