I disagree completely with s-xuer. The spread of MoC nominations is so great that the only stipulation of the whole process is "has to be submitted to the academies by January."
For example, my Senator had his interviews back in SEPTEMBER, and will be announcing interviews THIS WEEK.
I have a Senator interview this Saturday and the following Saturday with the Congressman. Still expecting a call from the second Senator. In my state all the applications for nominations had to be submitted by 12th October. Surprising it is that they started sending out emails with the interview schedules. All interviews on Saturdays and for 15 mins.
