At our 6th week PI, one RDC asked candidates what the third leadership trait was. So know the order (JJ DID TIE BUCKLE H).
And at ORLP, I was asked to define integrity. When you don't know it, don't pause to think about it or make a face or whatever, because then they'll hit you on bearing, too. Just come right out and say "This officer candidate does not know." Other than that, maybe memorize three to be safe. No one can be expected to know all of them, especially with Nav and NOS finals the next friggin' day.
