There was a preliminary phone interview done with the Account director. After that, they invite you to the office to talk with the rest team. These are four 30 min interviews with different people from the team.

Very straightforward phone interview. Asked about experience, interests, reason for wanting to work at Mullen vs other agencies. Friendly, interviewers were on time and very informed about the position. They answered all questions thoroughly and I felt very informed after my call. They provided email addresses for further questions, and were very kind the entire time.
