Lessons In Your Home interview questions

The interviewer called about 20 minutes late. I emailed them and asked if they would still be calling me. The tone was not as amicable as one could hope throughout the entire call. I could tell that they were not very prepared. Towards the end of a very question-heavy interview with no dialog, they asked me if I had any questions. I led with saying that I understand they are only overseeing the programs and don't teach as often, but how long have they been with the company and what did they love most about teaching the students. the interviewer responded (clearly not listening) that this interview wasn't about them and that they don't teach much anymore. They said they would follow up by end of week. I reached out to thank them, and there was such a strange response stating "we have your info if we're interested, we'll reach out."
