I can never get past an interview?

i would go online to the company website that you are applying for...just take a gander and study what their business is about and the products they offer...while in the interview make sure you maintain good eye contact and all those little tips and tricks...study some interview questions you think they might ask and rehearse your answers to them in the mirror a couple of time so that you don't walk into the interview not knowing what to say! just try to stay calm and keep your cool and be very confident!!! hope this helps some!!
