I want to be an OR nurse and currently work as a dialysis nurse, any advice?

Let the recruiter know how vested you are in the specialty area and your willingness to be successful and an integral part of the team. Start to explore classes and courses related to and inquire if they have an internship

They'll possibly require critical care experience with no last couple of years, and probably at least 2 years worth. I would advise looking into getting into the ER for ICU to see if you can work your foot in the door that way.
