Practice, practice, practice!
Seriously, there are a variety of standard questions that are
asked at interviews -- Google interview questions for
teachers, and you'll come up with lots of different lists.
Formulate responses/talking points for the ones you see on
multiple lists and get somebody to ask you those questions.
Practice responding to those questions until you've got them
You should also have a list of "talking points" -- things that
you are good at that you want to make sure you highlight
during the interview. Listen to the questions and see
whether they lend themselves to any of your talking points.
You need to work on finding a way to improve your
interviewing skills if you want to be hired.
