We are currently about to interview 2 great AP candidates for a 3rd time this weekend. In the meantime, a new "extraordinaire" au pair candidate who would be perfect for us came online (she has experience teaching at a school for kids with autism, and our DS is autistic) and we are talking to her for a first time, also this weekend.
How does one "buy time" in the interview process? I don't want to lose the candidates we are talking to, but I also would like to get to know this new girl? How do you know when someone is a great option vs. a match?
