I had an interview the other night I need some opinions on....

I had spoken to dcm last week, everything sounded great. Made an apt to interview this week. She arrives without the kids?! When I inquired why, she said she is doing all interviews first without the kids to make sure she deems me appropriate first then wants to do another meeting with the kids. I was kind of taken aback and offended by this, Ive never had someone not bring their kids to the interview. I did like her, she asked great questions and her kids seem like they would fit in. I also made it clear that I am interviewing her also, that I am meeting with other families and in order to go forward it is imperative I meet her children and see how they interact.

Do you think this is a red flag or just a very cautious parent??
