Pros
The teams at Express Scripts are highly collaborative, and the executive leadership has done a tremendous job empowering mid-level managers to make strategic decisions that move their individual departments -- and therefore the company -- forward. Employees are encouraged to stretch themselves, take smart risks, and think beyond their individual role. There are few other opportunities across corporate America where an individual can do such meaningful work for such a major company in such a newsworthy industry.
Cons
Express Scripts may not be the best organization for individuals who are uncomfortable in a dynamic, ever-changing environment. There is rarely a standard operating procedure for the important work done here. You must be OK with embracing ambiguity, and building something new.
