Digitas Analyst Strategy Analysis interview questions

After submitting my resume as part of the Campus Hire program, I was invited to the Boston office for 4 back-to-back 30 minute interviews. All but one were standard "tell me about your experiences" interviews, with the final interview being more of a case study. About two weeks later, they called and offered me the job.

I applied for the position on the company website and heard back from a recruiter rather soon after. Scheduled a call and spoke with the recruiter who went over standard inital phone interview questions, fairly basic. He then told me he was going to set me up to talk to one of their directors the very next day. Spoke with the director the next morning who wanted to know a little more about why I wanted to join the S&A team and why Digitas/tech agency world as I was in a different industry. Both calls went great and a day later the recruiter reached out to schedule time for me to come into their Boston office for four in-person interviews. Came in two weeks later for the interviews. The office if really cool, much different than what I was used to. First interview was fit/behavior, second was a case interview, third was fit/behavior, and the fourth was supposed to be a long case study but actually was a normal fit/behavior. Overall great experience. The recruiter was helpful and responsive throughout the entire process which was also great.
