Pros
Really great group of people, relaxed environment, encourages community involvement, really passionate employees, generous time off policy, a lot of encouragement to push yourself past your "standard" job title and evolve as an employee. You won't do well here if your goal is to show up, do your bare minimum job requirement, and go home. They want you to be innovative and to constantly be pushing yourself forward. If you're not passionate about the job and just watching for the clock to hit 5:30, this is not the environment for you. The people who succeed are the ones who care and want to learn and grow. It's an enthusiastic group of people who have a lot of love for the advertising business. Be prepared to collaborate and use your head. Laziness and indifference really don't make the cut here.
Cons
Sometimes your work day can get really busy, really quickly. But that's pretty standard across all advertising agencies. There have been certain managers in the past that have created a rather stressful and negative work environment. The most recent correction of powers has fixed this and alleviated a lot of stress. I can see how certain past employees could be bitter about the previous environment, especially the ones working directly under that supervisor, but it has been a much more positive experience since they changed things around.
