ReVend (NC) interview questions

When I arrived for my interview they had me and several other people waiting outside the guardhouse. They didn't have anyone at the guardhouse to direct you like the email they sent previously stated. Then a worker who we had to stop and ask for some help came back and told us that we needed to leave our information on some paper and they would get back with us! Very unprofessional! If we had a scheduled interview why would we need to leave our information and you would get back in touch with us?
