If the school you are interviewing with has a school website, get on it and research...what is the school all about? Review the course of study for kindergarten; you should familiarize yourself with the topics of study in case they ask you specific questions.
In our state, the reading initiative is highly emphasized. If this is the case with your state and the school you are looking at interviewing with, are you familiar with the reading initiative? Other than that, I got out my notebooks from my college courses and reviewed educational jargon.
I also looked at several websites and practiced answering interview questions. Here is a good website with interview questions they might ask:

Finally, BE CONFIDENT!

Good luck! I'll say a prayer for you. Let us know how it goes.
