Pros
Despite the 1.5 years of hell, there were a couple of very interesting and talented people that I was lucky enough to meet (particularly in the creative department). I also learned--in the most traumatic way possible--a lot about project management and juggling multiple responsibilities at once. If you can survive a year in account management at Mullen, every other job will seem like a cake walk. Mullen is also a well known company and has certainly helped open doors for me since escaping.
Cons
I started at Mullen as an Assistant Account Executive 2 weeks after graduating, and boy, was that a rough transition. To say that the senior management was un-supportive is an understatement. After a few weeks of work I was told that I always needed to be the last person on the team to leave. That meant if someone had to work until midnight, I also had to stay in the office until midnight--even if I had absolutely nothing to do. I don't think I ever left before 9pm. And of course there is no overtime and the pay is absolutely terrible. In addition to ridiculous hours, I found people in account management to be incredible petty and cut-throat. There was absolutely no team spirit. Everyone was out for themselves. I knew I needed to quit when one of my supervisors told me that I should never voice my opinions during meetings--even when what I was saying was a valuable contribution.
