I have a job interview at Boost Juice. What should i expect?

[lola.lolo]

I got a job interview at boost juice in sydney. The woman who called me said it would be at the actual bar in the shopping centre and it will be with some guy. What i want to know is, how is the interview going to work, because the boost juice bar in the shopping centre doesn't have a little office or anything. I'm currently in year nine in high school. Should i go in my school uniform? or i was thinking jeans flats a nice top and a blazer. Also what kind of questions would they ask me, what should i do to ensure my position at boost? Thanks
