How long to wait after submission?

Sometimes, unfortunately, it can take up to a week to hear anything, especially if the manager is off for a few days.

Some places will take a week or even more to get back to you - and then have the nerve to want you to start in 2 days! Some places do not bother to notify companies that they have filled a position until the company get hold of them and finds out.
What I do if I really want to hear back from a hospital is have my coordinator call the hospital and let them know that I am very interested in working at their facility, but that I have another offer I may need to accept by "X" date since I need to have things lined up and that if I know we are working on getting me to where I really want to be (their facility) I may be able to hold off a few more days.
This results in a call more often than not.
