First round interview from a non-target school was via Skype. The interviewer was very friendly, and the questions were all behavioral. I was asked about my leadership experience and items on my resume. It was nothing out of the usual, things like "Tell me about yourself", "Time you dealt with conflict", etc. I got the sense though that candidates from non-target schools faced more competition and were less likely to move on to the second round (probably because they will fly you to the main campus if you do).
