Sinegal interview questions

Applied for Concierge position and set up an in person interview for the following Monday. Arrived Monday for my interview and no one knew what I was talking about. Apparently that Saturday they let go of the manager I was set to interview with. They conjured up an interview with some team members and basically told me they have no idea what position I am interviewing for. They spoke with me briefly and then said they would chat and email me if they had the position available or not. Never heard. All in all, super awkward and very unprofessional.
