employers often ask behavioral questions. the purpose being to reveal how you have behaved in past situation and thus how you're likely to behave in future situations.
i had a phone interview 2 weeks ago and was asked these questions, among others:
"Tell me about a time you had conflicting priorities. How did you decide which was more important, and what did you do?"
"Tell me about a time you had an unpopular opinion, and had to gain acceptance of your idea from a group who disagreed with you. How did you do it?"
For your interview, you might be asked stuff like,
"Tell me about a time you had a conflict with another person, how did you resolved it?"
because they know parents will give you shit inevitably, and they'll want to see how you handle yourself with confrontation.
Or something like, "tell me about a time you didn't make a goal you set, how did you handle that?"
and that might be trying to see how you'd react if you have a student isn't learning quickly or if one of your people is having a hard time keeping up.
Stuff like that is important to think about, have examples from old jobs you've had or whatever life experience, and try and apply it if those questions come up.
