Kayte,
Keep the faith... as others said, there is a recession and this includes nursing jobs, and many new grads are also not working.
I suggest looking at non hospital jobs, and try nursing homes, dialysis, public health, doctor offices, and prison jobs. These are less in demand, and thus less applicants. Do not volunteer anything to them, and unless the application specifically asks about criminal charges which you have to say yes, say no.
Also, with any interview, be flexible, and willing to start part time, or agree to a 3 month period working with agreement that you can be let go if not doing ok, or even offer to volunteer, doing filing, or assisting pts with eating, or exercising...
Promise a commitment for a yr, or longer if they give you an opportunity... offer to work weekends, or off shifts... anyhing that will help you stand above others....
Be upbeat, and eager. Always ask questions, including if they have concerns about you or if there are things that they would like to know more about you... and send thank you and call also for follow up
dress professionally, be early, be polite, have a good resume, research the facility....
most of all, keep applying, the more applicatioins you fill out, the better your chances
keep us posted.
