Roundhouse interview questions

Applied online. HR contacted me and scheduled a phone interview. I was asked to then meet with a VP and the hiring manager. The very first question asked was “How long have you been in Utah?” This is an illegal question, origin is a protective class. Highly uncomfortable and inappropriate. The rest of the interview was a waste of time. At the conclusion of this poorly executed interview, I was told “you have acclimated very well to the Utah culture”. Who says that? What hiring process does this company follow to ask illegal questions? I knew right away that I would not want to work for them.
