The process took 1 day. I interviewed at Andersen (Los Angeles, CA) in Oct 2011
Interview
I flew to LA in the morning, sat in a room as 5 different partners, directors, and managers came through to interview me, then was put on a cab and flew back. The office was highly professional, but not very warm. Each of the interviewers asked similar questions. The most common one was "So tell me about yourself."
