I was contacted via e-mail (with a hard copy sent by snail mail) and they gave me the choice of a few dates in Oct, Nov, Dec, Jan. The program is UNM. I was really surprised at how quickly I heard from them, especially since I didn't have all three LoRs uploaded (but the LoRs were assigned so the programs could see who the third writer is). I now check my e-mail with bated breath, hoping to find another invitation...
Almost all of my programs have downloaded my info. One needs to get all three LoRs, and another needs to get everything. What's interesting to me is that supposedly the programs can't download your photo until they've offered an interview, but mine was downloaded by everybody...
