Hey Krishna

Congratulations on getting such a nice percentage and in getting CSE in VIT Vellore.

It is a nice college hence I will suggest you to go for it.

As far as NIT tag is concerned , as you may know some NITs are considered even better than some IITs but still your knowledge and experience will value more than the "NIT Tag". During th einterview you will be questioned on the skills that you have gained in your graduation and it wont depend on your college as much as it will on your skill. A person doing CSE (IOT) from VIT is a more eligible candidate than a person from CSE of any NIT(if it not a very very good one like Warrangal) if the VIT person has more skills.
