The process took 2 weeks. I interviewed at FCB Global (New York, NY) in Nov 2011
Interview
First, I was contacted on the phone by a member of the HR department. After asking me about my experience, they scheduled me to come in for an interview the next week.
On the interview, I met with 4 members of the analytics team.
The next week, I met with one of the VP's.
The next day they made me an offer and I accepted.
