I found it to be very organized and efficient. You meet with a handful of more senior legal assistants in various groups. The ask you questions about your availability and attitude for overtime, working on weekends, etc. Everyone had different questions, but they were all very pleasant and willing to answer any questions.

Classic behavioral questions--tell me about a time when you worked with a team, tell me about a time when you encountered a setback, etc. Initial phone screening with recruiter and then you're asked to indicate which practice group you're interested in.
