Go to local nursing fairs or job fairs.
Call, Call, Call....you have to harrass HR departments, otherwise you are just one of many.
Get referrals from those professors who think you are brilliant! They could be your greatest allies!
Go to your college career center.
Everyone has to apply online, you are already doing the right thing tailoring your resumes to their job. Nurses must be assertive to survive, be assertive and in their faces (in a nice way) Let them know who you are, and get to know who the nurse recruiters are.
You saw your fellow students as whiners, the recruiter saw them as wanting a job.
Good luck on your job search,
