Are you okay with working long hours?

Everyone has differing scheduling needs, and you know best what you can manage. If you have complete flexibility, that is great! Just share that you can work long hours, any day of the week. If you are unable to work long hours at all times of the week, you should share this information with the interviewer including which times you are unable to work. It's vital that you understand a limited schedule might eliminate you from consideration. Regardless; it is essential to be honest so that you can land a job that is mutually beneficial.
