Digitas Manager interview questions

Telephone interview followed by in office interview 1 week later. In office interview consisted of meeting with four different people one on one and one additional telephone interview with someone in remote office. Each of the four one on one interviews had a different format. One person did a general "What's your background" kind of interview. The next person asked a series of behavioral questions, the third and fourth person asked very specific business case questions. Everyone appeared laid back and easy going except for the final interviewer. He lacked basic professional courtesy.
