Camaco Quality Engineer interview questions

I was contacted through Indeed and set up for an on site interview within 2 days. When I arrived I had to wait for the General Manager for over 20 minutes in a folding chair near the entrance with no one acknowledging me. It was all very unprofessional and uncomfortable. After three interviews I was walked through the plant and informed that I would have to work work every day production worked even if that meant late nights and weekends.
