Hey Aspirant,
Considering placements, I’d say DTU = NSIT = NIT. Almost all companies that come for placements visit all these campuses, so the opportunity one gets is nearly equal in all colleges. In fact, companies like Google and Facebook have stopped visiting most campuses in India, and rather conduct an open test like APAC (for Google). So every college student has an equal standing in their recruitment process. It’s upto you how you present yourself before your recruiter.
So, choose either DTU or NSIT, you can't go wrong. Just work hard as much as you can after you get in, there's no limit to heights you'll be scaling.
Both my NSIT and DTU friends have made it big in life. They have worked/are working in companies like Facebook, Google, Microsoft, McKinsey, Bain, there are IAS officers, quite a few folks who made it to IIM, FMS, Harvard, Stanford, MIT, Oxford, University of California.
Get in and work hard. Don't waste the opportunity after you start, a lot of people start taking it for granted after they get into the college.
Good Luck :)
