Tell me about your previous job. What made you leave?

The interviewer wants to hear about your track record and experience working with families when they ask about your previous job.

Example: I felt like I belonged in the family as soon as I got the job. I began to treat the small kid like a little brother, and he looked up to me like a big sister. The parents asked me if I wanted to look for a new nanny job or continue with light work until the kids were older and in school. I went for the latter since I was hoping to get a full-time, long-term job.
