how to control my nervousness?

I used to have the same problem! especially in interviews. I look back and wonder why, I think the main reason is because i was so concerned on getting the job and wanting to impress the person interviewing me so much. If thats how your feeling than i would just suggest going in to the interview with an open mind. Think: So what if i dont get this job, it's not the end of the world, because its really not. Be confident. Most importantly, dont try to express how great you will be for the job instead, express yourself and the kind of person you are and let them realize for themselves how great you are for the job. As long as you have nothing to hide, your a decent person and have a good work ethic, you have nothing to worry about, the true test comes in the job itself. As for the black out deal ha ha, just dont think to much, you are who you are and you dont need to rehearse that kind of thing.
