"Schools hiring art teachers are looking for candidates with the passion to help students express their creativity and the formal education to properly instruct them how to do so. Expect to answer questions about your background in art as well situational questions that will assess your ability to manage and direct the classroom. When applying for jobs, it is helpful to know that public schools often require that you be a certified art teacher while private schools may not."
One thing that was asked was if I had a certain medium that I was more experienced and knowledgeable in.
Yes, at college I focused on graphic design. During my third year of college, I got an internship at a graphic design company and helped them make designs for their clients.
