I applied on-line, and Fed-ex'd my docs the following day (I sent them next day, afternoon delivery). My application went to the LA Consulate. They didn't look at my application until about two days after it arrived. The woman working on my application called me because she couldn't find my fiancee's passport in my papers (it was there, and she did find it). She called me the next day to discuss my application, but it wan't a scheduled interview. She did ask me a few questions, but her first comment was "when did you want your visa to be valid from", as I am not getting married until Nov, and applied in July.
I don't know if this information helps you. I don't know if I would have received a call if she'd not misplaced his passport. I did sent in quite a bundle of papers though, and she did make a comment about how was she going to get it all back to me.
Good luck! It was easier (and quicker) than I had thought, but perhaps it was because of all the helpful information I got from these boards!
