How would you handle the situation if the teacher does something you strongly disagree with?
This is a question about conduct. Behavioral questions are designed to determine how you reacted to or will respond to a situation you might face on the job. The STAR framework is the best way to address behavioral questions. You define the situation, the task you're attempting to do, the Actions you'll take, and the results you're hoping to achieve.
The main idea behind this question is to understand the applicant's thought process in this kind of situation. It is expected from the applicant that they should reply so that they focus on working successfully with the teacher even if they aren't always in agreement.
