I applied to the program and received an automated email to schedule an interview. Midnight before the interview, the interviewer cancelled the interview with no explanation and no response to a few emails. About a month later, I received another email to schedule an interview. That was a phone interview. A week later I had a skype interview, both about a half-hour. I applied later to the program, but they did say most people's second round interview was in-person in Philly.
