Upon joining any IIT, you’ll be termed as an IIT.This would essentially mean getting the IIT tag.
The IIT tag is not a material thing, it is not an ID card. It just means that you’ll become a part of one of the IITs. Most of the clubs and societies at IITs, especially the new ones, are student driven. So the responsibility of building and maintaining the campus culture falls entirely on the shoulders of IITians. But this experience is very beautiful and enriching.
The faculty and student communities at IITs are very helpful. The students help one another in every matter. The IIT tag wouldn’t get you placed in a company, for this you’ll have to develop your skill set.
IIT Tirupati will provide you with a lifelong experience, and you’ll forever be a part of the institution, even upon graduating from there.
