I think it really depends on the area of the country you are working in as to how "acute" the shortage is. Some larger states may find it easier to get call backs. I have never really had an issue finding simple staff nurse positions. Also depends on how many places you have applied it, if its 2 or 3 , it wouldn't surprise me if it took a while to call back. Some places depending on how efficient their HR dept is and whether it is the nurse manager who calls to set up the interview or someone else. I have applied at hospitals and didn't receive a call back for weeks - by then I had accepted another position. Also, it doesn't hurt to call the hospital, you have applied at and ask to speak with a nurse recruiter. I would ask about their current openings and state my experience - the goal is to get info about the facility. You never know there may be a perfectly good reason they have not called - possibly they are interested in internal candidates, position has been placed on hold, they aren't ready to start interviewing until they have several candidates, the manager who typically interviews is on vacation, they have the luxury of hiring a less experienced candidate (ie can pay less money) ... Anyway, don't get discouraged yet.
