Pros
Excellent name to have on your resume, Edelman is a well respected company and has an incredible history. Junior staff team is generally very talented and hard working. Ability to work on some big client accounts, adding terrific experience to your resume. Agency is usually ahead of the curve in terms of its vision and work it puts forward, providing for exciting client projects and campaigns.
Cons
Senior management team is a mix, some are incredibly supportive, while others provide absolutely no support and have zero patience. Hours can be extremely long, I generally averaged 50-55 hours per week, and often went over that. Zero work life balance for the junior staff team, and probably for senior management as well as they often seemed ridiculously stressed. VP of the office (whom I believe is no longer there, but led the office while I worked there) was incredibly impatient, short-sighted, and lacked the ability to give junior staff team members proper time to develop their skills. In one single week, about five junior staff team members were fired to the surprise of many.
