To clear the test, you should make yourself well versed in the history of indian cinema, music, literature and art, basics of photogaphy and cinematography, knowledge on recent events and developments in literature and cinema. You may get few questions like writing the sound track for a particular situation, writing a story from a picture, drawing a different view for a given picture, etc.
For the presentation, skills matter and your attitude and passion for the field. You may be asked to give a portfolio of your work at the time of Interview. Read as many articles and lots of literature. Read about important figures in the Art and Culture world in India, including famous people of the past.
Also, your general knowledge about current events is what they want to see. So, as much as you can practice and of course watch loads of movies, do.
I hope the answer could help you. Hit like or mark it as the best answer.
All the best!
