Pros
Some great people, very international, and opportunities to work for a variety of fortune 500 clients. As an entry level Account Manager, given quite a bit of responsibility and chances to actually manage client accounts. Great place to start out because of the freedom to grow by doing work that at other consultancies would only be done by senior consultants/directors.
Cons
Company culture is such that nothing but new business matters, not even when it comes to servicing current clients. Very poor management that is not engaged at all in the development or retention of employees. Few incentives in place to motivate employees to go above and beyond (or stay).
