Dependability is a big issue with recruiters as well. They won't wait for you in a job open house. Doors close promptly at the designated time. It takes a lot of maturity and stamina to do this job. Enthusiasm and energy.
Energy is contagious and interviewers love it.
Airlines like their image to be projected in a dignified, intelligent fashion. Anyone who is sloppy or awkward will not be considered. You must convey to a recruiter how you can pick up the ball when someone else drops it. Reflect this in your answers or speech. A sense of humor is necessary and appreciated.
