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.
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.
