It wasn't too difficult - basic questions that made you explain your previous experiences, what you want out of the role/company, and how well you fit into the company culture. It's a pretty laid back interview process.
I applied online. The process took 2 days. I interviewed at Caregiverlist in Jan 2014
Interview
It was nice and simple. The lady was very nice and told me everything I would be doing. She also cared a lot about what I was interested in to make sure I would get the most out of the internship.
