Very long, it lasted about four hours with a few quick breaks between interviewers. The interview started with a short introduction to the company. Then I sat with two different account managers for a half and hour each to observe what they do on a daily basis/weekly/monthly basis. After that, there was a short interview with mostly behavioral questions- very repetitive and hard to answer. The last portion was a situational activity where they gave me a fake company with a certain task and I had to propose solutions and pretend to work with a client- fairly easy and it seemed like the purpose was to see how the candidate can think on their feet and be creative. Overall the interview wasn't overly hard but there were so many opportunities to ask questions and it seemed like they were unsatisfied when I ran out of questions to ask them about halfway through the interview.
