I try not to think about to much (of course you want to look good and have a resume and references on separate sheets). I just focus on a smiling (I am fortunate in that I smile easily when not depressed) look at the person asking the questions in the eyes and try to focus on what they are saying so I directly address the question. My problem/ weakness is that I talk to much. If I stop talking after my initial answer--I'm usually good to go--but if I keep going I go off on horrible tangents. Each person has there own strengths and weaknesses--you will likely figure yours out during the 1st interview.....
