Are you able to offer a flexible schedule?

Before going into the interview, do some research on the company, employee reviews and the job itself. Often you can find out about what to expect with hours or potential travel. If you are working for a growing start-up company, it's likely that you be working long hours. Consider telling them, "I've worked under tight deadlines that required me to work longer hours. I have no problem being flexible, coming in early or staying late as needed."
