Rosetta is in the process of having its soul crushed after a series of corporate buy-outs. It now operates under the Publicis Groupe, and the shifting field of mid-tier holding companies and upper management is making job stability and advancement impossible.
Look for corporate doublespeak, ineffective middle-management, and feast-or-famine style work schedule. Rosetta is in the process of hemorrhaging talent from a raise/hiring freeze, and clients from a lack of mid-level oversight, non-existent long-term planning, and poor client-agency communication.
Good benefits and decent company culture, though. A good start for those looking to get a foot in the door of agency life, but not a place for anyone with any sort of experience.
