I recently had a peer interview with a hospital, and it went well. I got a tour and lead nurse of the unit gave me a tour and told me to ask HR certain things about orientation since it'll conflict with school. I got a call hours later from HR saying I have another interview with the HR department this Mon. Am I really going to be grilled again by HR? Is this just a formality? I've already interviewed with the Head nurse, staff nurse, floor tech, and even the Supervisor. What do you guys think?
