In fact English pronunciation can be very different in different parts of India, just like here as well. I know many New Yorkers behave like fish out of water in Alabama :) I have seen it in person.
Thankfully I am originally from Calcutta, in the east coast of India, where the English accent is perhaps on the neutral side. Yet, when you mention computer science, I can safely assume that most of those faculty are from south India. Even I will have hard time understanding that English! That is all that I am saying :)
But, our ears can be trained easily, and we can all get used to accents, it is all for the better.
