Discussed with the dean and the professor, it was very informal, it helped that I had a per-existing relationship with them and that I was very knowledgeable in the field the course covered.
I applied in-person. The process took 3 days. I interviewed at George Washington University (New York, NY) in Jan 2014
Interview
The interview process was fairly easy applied online a couple days later I received a phone interview then had a interview in new york. Wen to washington, DC to see the school and meet with some teachers and students.
