How many massages can you give back-to-back?

The answer to this question depends on your skills, experience, and the massage technique to be used. Typically, it's not recommended for a massage therapist to work for more than eight hours a day without breaks, as this could result in muscle and nerve damage. The interviewer probably knows this already and is just trying to gauge the current level of your skills. Answer this question honestly, and don't be tempted to exaggerate to be able to impress.
