hi, can you please clarify: you said one of your problems is that you dont' have your diploma, but i am confused because you said that you graduated from your diploma nursing program and now licenced to work? how are you licenced if you do not have a diploma?
if nursing is what you want to do, don't give up! you've done the schooling, you have the theory, now all you have to do is just put everything into practice! believe me, even if you're a fresh grad and ready to work (like me), it still takes time to get into the groove and feel comfortable.....
take into consideration that hospitals may have certain months of the year that they do massive hiring, then are slow to hire during slower seasons.....whatever the case, if you've applied and are waiting to hear back from the hospital, then you should be PROACTIVE and call them back to check the status of your application! most places keep your file active for 3 months....if you've been waiting longer than that, then i suggest that you apply again!
it may also help if you find out the name and fax number to certain managers of the departments that you want to work in, then you can submit your resume to them directly, instead of HR (process takes longer).....then call up the manager and show your interest that you want to work on the unit! sometimes it takes more than persistance before u land your first job.....JUST KEEP CALLING until you annoy them!! this has worked for several of my colleagues! it really just shows your determination and interest for working for them, so it's a good thing that you're persistent!
anyway, let us know how your job search
