It actually took me over a year after passing NCLEX to get a job. To be fair, I was in school full time for my BSN too, but it was frustrating being a new nurse and not working.
Make connections. Make people remember you.
If you get an interview, even if you don't get the job, make them remember, do something that makes you stand out.
I interviewed at a hospital in September and didn't get the position, but in December, out of the blue, she called be because she remembered me and called me in for an interview for a residency program.
The nurse managers who hired me were not looking for cookie cutter answers. They were looking for individuals who showed that they genuinely cared about people. I got asked "where do you see yourself in five years?", and I literally had no clue. I have no five year plan. I answered with "in five years, I want to be working, and caring for people (this is where I kissed the hospital's butt), because I've learned that life will inevitably not turn out the way you plan, and as long as I can wake up every day and do something great, I will be happy."
I have one story about connecting with this one patient from school that saves my butt in interviews. If you're asked a question about a situation and how you would handle it, it is always better to answer "when this happened to me, I handled it this way", instead of "well, I would probably..."
For the interview, did you send a follow-up thank you letter? Sometimes even something as little as that will make a manager remember you.
