Pavilion Bakery interview questions

It took them two weeks to get back to me, then the interview date and time kept changing. The interview then turned out to be an unpaid trial shift. I was then offered the job, when the owner got a phone call and left me to wait 20 minutes while he got distracted talking to other people. Finally he said he was going to send me the contract the same day. I only received requests for my day from HR the day after and after a week I still had not received the contract. I tried to reach out to the owner with no success. He only called me back once I sent him an email CC’ing HR in saying the position had been given to someone else
