It says in the confirmation email that you must bring your resume or else it will negatively impact their evaluation of you. So I guess that's a 'yes' on the resume. As for the questions, God only knows. Hopefully they'll stick to easy ones like, "What did you have for breakfast?" as opposed to "Tell me exactly why you want to go to law school and why you want to attend Northwestern."
To rip off someone else on this board, I'm going to tell them that I want my very own Bankruptcy Info Tapes commercial and law school is the only way to get one.
