I interviewed for the same thing in the DC office by phone about two weeks ago and just got an offer today. It was a short interview, about 20 mins, so it really flew by. I'm barely in the top half of my class, but I'm also a CPA w/ a masters degree so I would guess that had something to do with it.
I asked them in the interview about employment prospects after law school and I got the sense that it isn't as sure of a thing as it might be at a law firm, but there are already a number of this year's summers who have offers. So it definitely helps if that's where you want to go, but it doesn't sound like they have spots for everyone. I'm calling one of the alumni of my school who works there to get more info and I would suggest doing the same.
