Anand,
To be pesimistic, you should consider yourself very lucky if you are at all called for the interview. It seldom happens that a lot have been called for the interview. If you remember SIA coming up with a Cadet Pilot Program for India only last year, there were many applicants but only a few were called for the interview. Well, now being optimistic, u should be prepared to answer at least the principles of flight and questions related to general aviation.
But can someone help me in guessing if swimming is a pre-requisite as I really dont know how to swim and I have confessed that in the "Additional Information", would be glad if someone can answer!!!
