Computer Science teacher interview questions

Do you have an interview coming up and want to get an idea of the type of questions you may be asked? Are you a subject leader and want to have a list of suitable subject-specific questions you could ask in an interview?

Here we have compiled a list of 45 questions covering technical questions as well as subject-relevant pedagogy questions which are useful for both the potential employer and interviewees wishing to prepare.
