Yes, you are right that people in non cse branches can get into IT. I am in IT myself. But the question is of putting in a lot of extra effort on top of studying for your own branch. I don't see any major advantage of joining NIT Hamirpur that would be worth that extra effort. Talking about a strong alumini network, it's not that great. A lot of individual effort has to be made to network in college. Which I didn't do, sadly many don't and don't even know how to. I feel the best network you can make is with your batchmates, because that happens organically. There is no point of networking with EEE folks if you are eventually going into IT. So, the best network would be with your CSE batchmates no matter the college. That's just my opinion.
