Waiting game begins after Kellogg submission

I have been missing from the blogger for a week now and the update is - I have submitted Kellogg! In the end, I felt it was not my best application. That honor probably goes to Columbia. I think thats the strongest of the 4 I have submitted.

So, the waiting period starts from now. Chicago wants me to wait till Mar 26. Columbia should give me a decision in 12 weeks and my application hasn't gone under review yet. Kellogg too is somewhere in early April. So, its time to chill out a bit.

I am still not sure about how Columbia invites for interview. I mean, when is the earliest you can get an interview invite after the application goes under review? Any ideas?
