one thing thats always helped me too is when i'm in an interview i knwo the times i strolled in there happy positive and confident things went well. UNLESS the guy on the other side of the table was conceited or something being confident in the presense of someone like that seemed to backfire they seemed to prefer someone who hung there head low and lacked some confidence. I guess they want a wipping boy or something lol. In my case I didnt feed into that. Because more often then not being positive confident and smiling was the key. Even tho my car might be about to be repo's and my life might be falling apart I never let any of that on in an interview lol.
