Pros
The Edelman team, from Richard himself to each Assistant Account Executive, are simply the smartest group of professionals I've worked with in this industry. Having worked at two other large agencies, I can confidently say the level of talent at Edelman blows other agencies away. Senior management is incredibly involved and accessible and although it's a huge company, it somehow maintains a small, start-up feel. I think that's because they strongly encourage an agency-wide "entrepreneurial spirit," which empowers teams to pursue boundary-pushing programs for clients and employees to pursue limitless opportunities in their career path.
Cons
If you don't have a strong POV, presence or outgoing personality, it's easy to get swallowed up at Edelman. Although it feels smaller, it's a huge, global agency at the end of the day and it truly gives life to the phrase "jump in the deep end and sink or swim."
