Hey shannon!
I really think that what they are looking in a person, is someone who can work as a team and someone who has enough stamina to deal with several hours of work without losing his charisma.
For example , if you look tired ( your sitting position in the chair, your posture , your face ) , if you're trying to hard ( look at the recruiters like saying ' look at me' ), if you don't respect your mates opinion ( like saying ' I think you're wrong' or interrupting someone when he is talking ) or if you stay too quiet and shy...END OF THE ROAD FOR YOU THAT DAY BABE!
Good luck there!
Cheers!
