I was referred by a good friend of mine who worked there. She really loved it, but decided to leave to go get her master's degree in social work. I interviewed at 3 different locations and the directors of each program decided where I would fit in the best and where they could use me.

Maybe one of the least formal interviewing processes you'll ever go to. They usually invite you in for a chat and often have you meet the clients then and there or invite you to meet them at a later date. I had two supervisors while there and they both did it a little different. They do seem to want to see how comfortable you're going to be working with the clients and if they like you.
