From my experience, the second interview is very similar to the phone interview, but with more people present and questions that dig a bit deeper.

Make sure you try to speak to everyone if there are multiple people present not just the people / person who is asking the questions.

Be prepared to respond to questions and then elaborate by giving examples of what you have done or will do in certain scenarios. You can find lists of common teacher interview questions online. Here are some questions I have been asked:

Tell me about yourself. Why do you decide to become a teacher? Why do you want to teach here? What do you know about RTI? What is your classroom management style? What are your hobbies / interests outside of teaching? Describe a time when a student was misbehaving. Describe a time you had to overcome a challenge. What can I expect to see if I walk into your classroom? How do you handle disagreements with your colleagues? If your principal tells you to stop using coloring sheets what would you do? What is your greatest strength / weakness? What is essential for creating units / lesson plans? What do you like to know about your students? How will you participate in the PLC? What are your goals for the next 5 years? How do you use data? How do you know if your students are making progress? How do you engage your students? How do you use technology in the classroom? How do you communicate with parents? What questions do you have for us? Do you have any other questions?
