Skin Matters interview questions

I was contacted by the interviewer and right away asked if I speak mandarin is that even legal? The process took so long and there were a few phone calls back and forth I believe four times just to call me back to confirm and to schedule and reschedule. At the interview they asked me if I would move closer to work .. I said no and was questioned by the interviewer again why I wouldn't. Are you paying for my rent? That's a dumb question to keep asking when I gave you an answer. I was never contacted by them again after the interview because they are looking for someone full-time when the job posting says part-time.
