^^^ what he said. And this goes for any interview. Spend some money on your visa. get a suit that fits well. Something you've purchased in the last 30-60 days that your dad didn't wear and you didn't try to get laid in at prom. Iron your friggin shirt and put a shine on the shoes. Walk tall and carry in a good attitude. jetblue doesn't test your flying skills in the interview, but if you walk in looking like a disheveled slob, what do you think that says?

Play the part for a few hours then go back to being a slob at the bar
