I'm not sure where you're located but don't lose hope. Have you looked at smaller hospitals, rather than the big most popular ones?
For example, Paradise Valley Hospital in San Diego offers almost all of their RN positions for new grads but it is not a new grad program. I do know that they will train you, but do not know the extensiveness of education part like other new grad programs or if they even do classroom type learning.
Perhaps it is not your "dream job" but it can catapult you into your career of choice.
Do you check job postings with every hospital you are interested in every day? It might sound like overkill, but some like Kaiser, only have their posting up for a bit. Be the first to apply.
Perhaps your resume and cover letter need a revamp? Do you currently work or volunteer? Perhaps highlight those skills for the time between graduation and looking for a job. Good luck
