Yeah, I've been wondering about this too- many schools list their due dates for deposits for each round, but some don't. For instance, Stanford and Booth both do not have deposit due dates posted.
Most of the schools I've looked at have round 1 deposit deadlines that occur prior to round two decision notifications. Kellogg round one deposits are due March 7th, and MIT-Sloan round one deposits are due March 25th.
I'd be curious to hear some of the experiences of others that have already gone through this process. Has anyone gotten a round one acceptance, put their deposit down, and then gotten a round two acceptance from their dream school?
Of course, I should be so lucky to have submitted a deposit to Kellogg or MIT and then be in a bind because I got accepted to Stanford...I can hear the tiny violins now...
I think the best advice is to only apply to schools you genuinely want to attend. To be honest, if I get into my round one schools, I will seriously consider withdrawing apps at my round two schools.
I have a spreadsheet of b-school deadlines for this year, I will try to post it. It's helpful to have all the deadline information in one place.
