One thing everybody needs to understand is that, no matter which college you join, you will not get a satisfying success unless you thrive for it, and yes colleges plays an important role in building your personality, attracting the companies for recruitment and etc.. but at the end of the day, it’s you who will be facing the interviews or going for start ups. So no matter where you are, it’s your efforts which pay off.
And coming back to which college, I’ve heard that VIT is really good for placements and in teaching technical approaches, and if you see the number of people who’ve reached the sky from colleges like both Manipal and RVCE is also pretty good, and I would say choosing any of these three is not a bad decision.
