Check out this current reflection on Skype interviews over at Episcopal Café which borrows heavily from The Rev. Dr. Victoria Weinstein aka Peace Bang of Beauty Tips for Ministers
I have only experienced on Skype interview, having by and large gotten out of the looking for a new call stage of life. My only observation is that it is a technologically one-sided process. The interviewing committee will get an up close and personal image of the clergy person, necessitating attention to nose hairs among other things. The clergy person, on the other hand, gets to see a large committee sitting around one camera. They appear as dots on the interviewee’s screen. Its hard to read their body language, let alone see any stray hairs.
