According to me for CS LNMIIT is better than Thapar, Pls remember that today’s Thapar is not same as what it was 10–15 years back number of seats have increased exponentially, quality of students have degraded a lot so its quite evident Thapar is functioning like any other greedy for money private college. Even if the number of companies visiting Thapar is more then also due to less student strength LNMIIT is in a better position and also the coding culture at LNMIIT is way better than Thapar, easily comparable to Top NITs, Bits, etc that is evident from the GSOC selection from LNMIIT. I think fees in both institutes is around 16–17 lakhs so that does not become a deciding factor
So for me, LNMIIT is straight away better than Thapar.
