Few questions about your skills. Availability and do you interact with kids. They explain there needs and about their background and company background. The interview was 15 minutes. Got a offer and waited for the email for background check.

Simple, introduced and multiple questions about yourself, your experience with children. Then they give you a tour of the facility. Some interviews if going well they ask to see how you do with the children and have you go into the classroom for 10 minutes.
