"How do you feel about overtime?"

If this is an hourly job, then pay is given to employees working extra hours. If it is a salary position, most of the time they will not ask this question because they expect you to work overtime. But expect this position to have some overtime requirements if the interviewer is asking this question.

"I don't mind working overtime at all. I know during busy times people are expected to work more, and I'm flexible with my hours so I won't have a problem."
