I applied online. The process took 4 weeks. I interviewed at Northwell Health (Manhasset, NY) in Mar 2016
Interview
I was interviewed with two other girls, but some people interview individually. We were kindly asked questions about volunteering and the hospital setting in general. There was also a follow up orientation.
Short interview that involved asking your career goals and where you would like to be placed. It was very relaxed and is mostly a means to learn about your character.
