Enhanced Group One interview questions

VERY weird and inappropriate interview. I was locked out of the office for a good 10 minutes and the only reason I was let in was because an employee was storming out after having a very loud and public fight with the owner. He then proceeded with the interview but was clearly distracted and still upset from the fight. He then asked questions about my living situation which I believe was illegal but I answered anyway. In the end he offered me the position, said we'd be in contact, and then was never able to be reached again. I tried everything but he just disappeared. Very unprofessional and made me very uncomfortable.
