How many hours would you like to work per week?

"I am seeking a part-time position, as advertised. I would like to work my hours around my kids' school schedule but am flexible with some notice."

Share with the interviewer the ideal work schedule for which you are looking. If you have restrictions on your schedule, this is the time to mention these. Typically, interviewers will look for someone with flexible availability. If this is you, take the opportunity to showcase your willingness to work whenever needed.

"I would like to work as many hours as possible! My availability is flexible, and I am ideally seeking a full-time position."
