Pros
There are many quality people working at Express Scripts.
Cons
HR department does not have a clue how to screen for, how to evaluate positions, and what functions are actually performed by IT positions. This ignorance about IT positions causes them to undercompensate for certain roles within the IT department which leads to a revolving door. HR also has a misconception about the difference between a contractor and an independent contractor. I know in one instance that a contractor was there for almost 18 months and the HR department forced this person to accept a perm position for 35% less or have to leave the company because they said that it was a law that contractors cannot work for more than 18 months. Some of the IT groups that are on call for the weekends must remain available and are not compensated for their availability. The on call person only gets paid if they get called.
