Highflyer good luck on your interview.
I hope things haven't changed in the past yr or 2, but traditionally Burr interviews only to make sure the candidate on paper matches up in person.
When DS went through it Burr had 2 slates, I would think he may have 2 again this yr, since DS is graduating. You won't know until later.
At the interview he had 22 candidates for 20 noms, so the chances are good.
Burr, unless he has changed does not do principal, it is unranked submitted alphabetically.
The letter of the nom showed up at the door within days. I think it was by Wed/Thurs. Like I said it is just a verification process.
The board was a committee and Burr was not there. It is a cross mixture of leaders in the community and military people.
They all had the chance to pepper him with varying questions from Academics to books to ECs.
Keep us updated.
PS. He wore khakis, a button down oxford and loafers, and got the nom.
