The closed file interview is much, MUCH more likely to start with "So, tell me about yourself."
That can be good or bad - bad if you're not prepared, and stutter before saying "Um, Leo, chocolate fiend, likes romantic dinners and candlelit walks on the beach."
But if you've prepared ahead of time, you get a really excellent chance to sell yourself, putting forward the things that are best about you and leaving out all the bad parts!
At the start of the interview process, I hated closed interviews, but now I think I like them a lot, mostly because I can come across as much more enthusiastic in person than in writing.
