Brightree Customer Service Representative interview questions

Had an interview with them. First phone interview with recruiter went fine. She told me a bit about the company and sent some brochures to my email, went over that for the following video interview the next day with two managers. Immediately felt so uncomfortable they were asking too many personal questions I did not feel was necessary. I found the tone of the interview to be more critical than collaborative, which impacted my ability to communicate as effectively as I would have liked. Also when asked if I know about the company and the role I told them yes from the job description and being told it is a Customer service role, placing orders for CPAP machines. One of the interviewers immediately went into that is not all that we do and then continue to talk about placing orders for CPAP machines, which was contradicting.
