Sometimes there are set pay schedules. For example, I'm a physician. Physicians in X specialty at my clinic start at a salary, physicians in Y specialty start at a slightly different salary. There is no negotiation. That is the salary offered. It increases with each year at the organization. Everyone has the same access to other ways to increase salary (like taking after hours calls nets everybody the same bonus).

Maybe ask if that's their setup. A pay schedule that's predetermined. You might mean to ask the range of possible salaries depending on factors like experience, and they may misinterpret your question to mean a negotiable range in which your personal salary might fall.
