Multiple people will probably interview you. Bring resumes and have cover letter and letters of recommendation ready. Don't dress up too much--outfits are pretty lax so you will stand out negatively if you wear a suit or gaudy gown.

Met with several supervisors, they had previously had access to my performance reviews and other supervisor recommendations. Talked about the position and requirements. Short and sweet mostly they had a good idea what they were looking for and wanted to meet to make sure there was a connection.
