Phone interview with HR then came into office to interview with Associate Director and two supervisors on the account. Two days after interview received a call from HR with verbal offer and had one week to accept or reject.

I applied through LinkedIn and scheduled a quick phone interview with a recruiter, who explained the open positions to me and gauged my interest in the roles. She sent my information over to several teams, and scheduled in-person panel interviews with the teams who wanted to meet with me. Interviews were conducted in the office in 30-min blocks with two-three people interviewing me at the same time. They consisted of basic "tell me about yourself" questions as well as behavioral/scenario questions. It was a little unorganized since they didn't book rooms in advance, but everyone was tact and respectful.
