I met with the Site Manager and the group manager for about a half hour. It was pretty informal and laid back. There was not much emphasis on qualifications. More of a personality evaluation. The main thing that I believe helped was being personable and being able to handle questions without hesitation. There is no second interview, it is a one shot deal in the site manager's office. Even though no one on the floor is in a suit and tie, everyone that interviews is expected to do so for the interview. References are a must though. They called 4/6 of the references I have (3 professional and 1 of the 3 personal)
