ARGH! Interview alert!!

24 hours before I'm meant to be sat in an interview for a summer job and I find out about it! I've got to think about this one cos I can't remember any of the tricks that have got me jobs in the past. I can't even remember what I put on my application form! Good work!! Its £300 that I might need over the summer so I'm not going to take it lightly! Wish me luck.....
