Pros
There aren't any really. There are a few smart and decent people who work here, but this is one of the most unprofessional environments you can imagine. Unethical behavior is rewarded, backstabbing is expected and trust is not known amongst those fighting their way to stay employed amongst this harsh and volatile work place. You can get paid well if you are in the beginning of your career provided you take the abuse from the CEO and all other supervisors.
Cons
Everyone is expected to bring in new business - especially if you are a senior PR professional. The CEO is a very mean and unfair person with a penchant for the irrational. He will berate you via email and then fire you for no other reason than he doesn't like your trying to defend yourself from unfair criticism. He is aggressive and imbalanced. All you have to do is Google him to see the tons of bad press he has gotten through the years, though I know for a fact he has hired SEO firms to bury it - and from what I see from these totally false reviews of him and the firm, I guess it is working. There is an almost Lord of the Flies atmosphere around that office as all of the senior management are trying to protect their own jobs, they have little care for their fledglings or colleagues. Long unreasonable hours are expected. And, unethical business practices are the norm. The CEO will accept any client for any type of fee just to get them in the door, even if they are not right fit for practice. It is a terrible place to work. Period.
