No matter what they tell you, this is still a PR shop, and work suffers because of that. Clients won't let you out of that PR "lane" because they already have other creative agencies, and as such, you spend a lot of time putting together decks for lackluster ideas that probably won't get produced. The creative department is also EXCEPTIONALLY top-heavy (everyone's a VP), meaning opportunities for growth are few and far between.
This is not a place to build up your book, it's a place to build a comfortable living and start a family, which can really hurt creatives who are looking for more in their career.
