Hy ipsita!! 

First of all , all the best for your interview. Look as your course is mass communication, they are going to check your communication skills, your attitude and confidence. So be confident there and amswer the questions in a decent way without hesitation. 

They may ask you the reason why you wanna join this course, who is your ideal, how did you develop interest in this area and some of your qualities due to which they should give you admission.

Hope it helps!! 

May you clear your interview tomorrow.!! 

All the best
