I've always wondered this because I one had a PRN job as my only job, but I've never had a PRN position in addition to a FT position. I've applied for PRN positions while working FT but have never gotten a response to my resume or application, unlike with the hunt for a FT position. What does it take? Any tips? Is it better to contact the hospital or unit directly? Is there some sort of secret code or password that I'm unaware of?
