Bring resume. Please please dress like your going to interview clean and neat. I talked to a manager at the office and then he called another manager and I did an interview over the phone so they can get a feel in how I would be over the phones. Make sure you speak clearly and don't over think or over analyze the questions they ask. Be calm and cool and just be your self. If they ask you to come back for a second interview then you probably got the job.
