From what you wrote, the employer doesn't offer alot of information. For instance, what type of company is it? Is travel required? What client population is to be case managed?
Home health case management is a good foundation for most case management experiences. My experience with HH CM was that I had to provide direct care as well as coordinate services. In an area like workmen's comp, LTC, hospital, behavioral health or insurance, you don't provide direct care, but you have to be able to relate your experiences of direct care with each of your cases.
I invite you to go to the
www.cmsa.org (Case Management Society of America) website to get information and resources on CM. Best wishes with whatever you decide.
