Contacted by their HR. Interviewed once with HR, once with campus director. Took an AP Physics sample exam to prove knowledge of subject. Taught a demo class to prove competency in teaching.

During the interview, they asked me about prior teaching experience. Then they gave me an actual AP Physics exam (multiple choice, covering AP Physics 1 and 2 material). After the exam was graded, I was interviewed a second time by the campus director. Then I taught a trial class. And then I was hired.
