Always bring extra interview materials to the interview - even if you've sent everything ahead of time. Carry a folder or envelope to the interview that contains:

• A copy of your Résumé for each interviewer.
• Copies of your reference list.
• Paper and a pen, so you can write down the interviewer's name, the time of any future interview, or other information you might need later.
• Copies of letters of recommendation, if you have any.
