If you are a paid intern, or an employee who is called an intern, you should be subject to overtime laws. If you are an unpaid intern, you have fewer protections from the law, and may be legally asked to work long hours. If you are an unpaid intern and are working long hours, you should assess the criteria for unpaid internships, explained in Question 1 above, to determine whether you should be classified as an employee. If you are not an employee, you could consider whether the long hours are worth the learning experience you are receiving.
