Or that they don't have the budget to fill?
I'm seeing the same job posted on their hospital site for a while now. I have been slow getting all my resume and referrals together and when I called about the position I was told that it's posted till it's filled. It's just a nurse aid position, how long could it take to fill that job? I'm sure there are tons of qualified applicants for it.
I just thought it was odd.
