Roughly 4 interviews, one including a mock up of a fake campaign that you walk through with the deciding manager. First few interviews are very behavioral based and look into your creative mind.

The interview process was extremely uncoordinated, unorganized and unprofessional. I had 4 "interviews" which were calls with different people at offices across the US. For each call the interviewer was late and didn't even know what I was applying for. Most of each call was just updating the person on what I talked about with other members of the team, because there was 0 communication across the team. I had to send at least 2-3 follow-up emails to even get a response. This was the worst interview process I've ever experienced.
