You phone interview first. Then you may make it to the day-long interview. The day long interview consists of some team working projects, analytical tests, a sample teaching, role-playing and a one on one interview. In the team working projects, make sure to be inclusive of all people, be respectful and open minded, listen well, and share your own ideas. In the sample teaching, the most important piece is the reflection afterwards. Be sure your lesson has a beginning, middle, and assessment at the end. The people were very professional.
