The interview was a one-on-one with a junior associate who asked the typical interview questions. The interview was easy, relative to all of the other legal jobs offered to law students. I think it is also important to point out that the firm seemed to only interview when they needed law clerks immediately, resulting in an offer of employment immediately after the interview, which was nice. They weren't picky as long as you proved to them you were competent and were willing to work hard.
