If I can respond for Amarilla in my reply, I'd say it's harder in NJ because facilities ask so much of new grads. Hospitals want 3-5 yrs experience in North NJ (near NYC); agencies don't have the capacity to train new grads, so they can't send you on jobs; nursing homes, SNF, adult day cares want 1-2 yrs experience; doctor's offices are never hiring (who would leave those jobs); to get a foot in any door you've "gotta know somebody"; and to top it all off everyone wants a nurse with a BSN, not an ADN (like me).
I don't think it's only in NJ but the combination of all situations (and I'm sure I'm leaving things out) makes it tougher in NJ. Plus, people here are just generally rude. There is no time to help a newbie out; it's all business. I got a callback once from someone in FL. Although she was quite clear in not wanting to hire me, she stayed on the phone with me to tell me why she called, what she thought I should try, and wished me luck. I never got that from anyone in NJ; not before or since.
