Pros
Good benefits, my boss in particular is very flexible, decent pay, lots of options to move around in the company
Cons
Don't expect to move up based on your work ethic or production. Centene is all about the years you have been at the company, unless you can attach yourself to a manager that will pull strings. It's been stated in my department that they will never hire a manager from within (that is, if they promote you at all/ you're better off transferring departments for a promotion). They dangle carrots to get you to stay, but rarely follow through. My department in particular has 100 people and have promoted maybe 5 this year. HR is incredibly slow. Also, if you don't work at the main office don't expect any perks (good cafe, covered parking, health fair, anywhere to walk without getting hit by a car, etc).
