Very straight forward. Principle and VP and you to explain who you are and what you'd like to do. Ask how you would feel about specific grade levels, getting a feel for where they should place you.

I received an email to interview with the principal and admin team. I was asked to come in with a lesson prepared for any grade level, even though I applied for a very specific grade level. I was walked into a classroom and was asked to teach my lesson to students I'd never seen before or had any background knowledge of. After the 30 minute lesson, I was taken by the admin to receive my score and feedback as well as asked questions about classroom management, work experience, etc. Having worked in functioning school districts, I felt this was inappropriate to put me in front of people's children when they did not know who I was and I was only there for 30 mins. This is disruptive to a child's day. I can only imagine how many other applicants disrupted the students learning.
