Chef on Call interview questions

Just a basic interview, they were pretty desperate for staff. They hired me right on the spot and started my 3 hour (unpaid) training right then and there. The owner interviews you and he seems nice and first but he's a horrible employer. He will tell you that they aren't cheap and that you'll get a raise after a couple months but that never happens and when it does happen it's only a 5-10 cent raise.
