There were multiple interviewers, across different levels, from associate to seniors and partner. Interviewers took turns asking questions and there was a lunch that was also offered. Employees seemed knowledgable, though busy and it did seem like people were required to participate in the interview.

Panel Interview three or more people. Personality based. Situation/problem solving based. Not about resume. About you as a person. Very detailed questions that create stories for you to tell about yourself.
