Read through the portion of last year's thread for Round 1 applicants and it appears the deadline to submit was one week earlier than this year (approx. October 6th) and the first invitations came out the last week of October. It also appears the first interviews last year might have gone to international applicants, although there was debate in the thread if that was actually a pattern or just a byproduct of the small sample size of people posting in the GMAT Club forum. The majority of the invitations came in the middle of November with some members getting invitations to interview as late as the second week of December. It looks like mid-November is when most of the interviews came the in 2009 as well.
If Stanford follows a similar schedule this year, than we should start seeing interview invitations come out next week, but we may have to wait till mid-November for the bulk of the invitations again.
Maybe this year will be completely different, but I thought I'd post this for anyone who is obsessively checking the board or assuming that Stanford will send a big batch next week since their application was due 10 days after Harvard.
