Another perspective.
I only hire older APs.
I would NOT be put off by an AP who asks about curfew and use of a car. She may be from a country with a very active AP network and they know what it means to have a curfew and be stuck without a car. So she knows what she wants -- a good thing. I personally would never accept a curfew or work for a family that doesn't give me fairly free use of a car.
I also don't care if my AP goes out every night, as long as she is ON for my kids when she is workings, as the PP said. Again, I only hold my AP to the same standard I would hold myself. I don't expect more of my AP than I would do.
My current AP goes out a lot, almost every night, but does not drink, and is defintely on for my kids. In fact, she does so many fun and creative things with my kids that I have asked her to tone it down because they now expect me to do the same thing,
I do not put a lot of stock in prior experience because it can be embellished. As someone above said, you want the right personality, level of energy, and ambition.
I just clicked immediately with my AP. It is a gut feeling. Personally, I do think that having an AP with really really good English is important. It makes it that much easier to have a really good relationship.
Good luck.
