Yeah! NIT students gets good exposure to the subject as well as career growth and placements. Although this NIT's are the top NIT's. For the new NIT's, the scope is less as they are all developing. I won't say bad but its not satisfactory. Thus if you wish to go for NIT and you are getting the good ones such as Trichy, Warangal etc then you can go for it. And also its a matter of fact that getting good skills is the most important. Be it from NIT or from private college, if you have skills then believe me you will build your own opportunities.

I hope this answer helps. All the very best for your future endeavors!
