This is getting ridiculous

I interviewed for a job 4 weeks ago, was told I had the job that I just had to wait for the req# of another position to be posted and to get a salary quote. I called last week when that didn't happen and was told that my references had been checked, but that the req# still hadn't posted so I couldn't get a salary quote but that he still wanted me on board. I told the manager that I had applied for another req# and was told it was day shift, not night shift like I wanted. However he called me back and asked if I would mind doing my orientation on day shift, then he;d be able to put me on night shift. I of course said yes. This was last monday, its now thursday. Still no official offer of the job, which is the salary quote from HR. I call and leave voicemails, but don't get a call back. Should I give this more time or give up? If I give up I also give up a chance to go to the University of Kentucky's RN-BSN program as this job is at a hospital affiliated with UK and tuition is waived for up to 8 credits. This is the first real nibble I've had since I started looking for an RN position in Feb, 3 months before graduation from my ADN program. I can also now schedule my NCLEX exam and really should be worrying about that, not getting a job.

I am about ready to say the heck with it and apply for NICU jobs in Indiana, even though I'll have to wait until I take and pass the NCLEX to apply for licensure in that state now.

I am just so discouraged right now.
