Laura, you can do it!! The night before the interview, get a good sleep and try to relax. Think positive and remember, they asked you for an interview, so there's a good chance they're very interested in you. Also, it's very positive your manager is supportive, he/she must think you're the one for the job!

I once found a list of the 100 most asked jobinterview questions on the net. I sat down and typed all the answers out - be honest, as I'm sure you will, and think about how to put it. Perhaps go through that list with a friend and you're halfway there. Also make sure to wear clothes you're comfy in.

I think we all hate to go for jobinterviews, but just take a look around you and see who else they've got to choose from, and you'll be fine!!

Best of luck! You'll get the job!!
