Riverstone Veterinary Group interview questions

Was contacted quickly for a working interview, and given a run down of the general of the grooming side of the business. When I came in for the interview I was greeted by the manager, then left to my own devices in the grooming area where I waited over 45 minutes before any dogs were brought in. The equipment was subpar, and lacking for what I was scheduled for the day. I was asked vague questions about where I lived, currently worked, and about myself. I was not given any idea of what kind of working interview I would be doing, the dogs on the schedule. I met the owner briefly, but when I was finished I was told I did not have to wait around for the final dogs to be picked up, and was not asked any follow up questions. I was also not compensated for the 3-4 hours of work I completed.
