What is your scheduling availability?
Before answering scheduling questions, you should be clear on the interviewer's expectations. If you haven't had a chance to clarify their scheduling needs, now would be the perfect time to ask! Consider asking, 'What are the scheduling expectations for this position? If their schedule expectations won't work for you, consider what you CAN offer and see if you can meet in the middle. It's much better to discuss these things in an interview than commit to a schedule that won't work for you.
"I'm pretty flexible with my schedule availability. I prefer to work the earlier morning or day shift, but I'm open to afternoons or evenings to start if needed. I also prefer to work a full-time schedule, and can work weekends."
"I'm open to working part-time or full-time and can work 8 or 10-hour shifts as needed. I'm available every other weekend and can work holidays as long as I have advanced notice."
