Cortland Leasing Consultant interview questions

All questions were normal like what are you looking for in a company basic questions an interviewer would ask. Then I met with the assistant manager and it was all ok until she indirectly asked me how old I was by asking how old my son was then she makes a statement you don’t look that old still without me telling her my age. How rude!! This question is very illegal to ask and I knew at this point they would not be calling me back because of that statement. I am now seeking an attorney as this question was totally illegal. And this is what I meant by a mean girl atmosphere as you could clearly tell by the assistant managers response and look on her face and how she immediately wrapped up the conversation. The home office will definitely be hearing from me or my attorney.
