I would suggest that you be yourself. In addition, answer them what you really think about the questions you'll be asked. It's noteworthy to realise that you can reply them slowly as English is not your first language. (Hopefully, I think the interviewers will understand)
I'm quite sure that you will first be questioned about your background. Also, they will ask you why you choose to further study there. More importantly, as mentioned in a reply above, you'll be asked about current issues which are related to your field of study. In order to do well in this part, you have to know a lot of information. They may also ask you to analyse the topic, and so on... At that moment, do not be panic. As I told you, answer what you think and everything will be fine (hopefully, again, 555++).
Furthermore, you may be asked about the religion. For this, I was asked how frequently I go to the temple and take part in religious activities. Also, I was asked to explain them one sermon of Lord Buddha.
I wish you a fine interview.
