Is it common to be hired by your internship site post-licensure?

My girlfriend and I are planning to move in together. We're currently long-distance (she's in New Jersey, I'm in Maryland). I'm currently enrolled in an online CMHC program in Maryland that trains for Maryland licensure. We've been brainstorming where we want to live, and I've heard that it's common to be hired by the same place you had your internship. If that's true, we would likely need to find a place in Maryland since I'm not training for New Jersey licensure. If someone knows, that would be really helpful!
