Just be yourself, look smart and confident. Dun worry about language barrier just keep practice.
Prepare few standard questions, like why shd they pick you, why this uni, why pharmacy, read some pharmaceutical journals. (but remember dun just dump everything out from your mouth as if you are just remembering the standard answer, try to talk naturally and have discussion)
I think most interview (not just pharmacy), sometime they start off with "tell me little bit about yourself"
