Pros
Centene has above average salary and good 401k options. It also offers a lot of challenges and unique problems to solve, if that's your thing.
Cons
Work/Life Balance is non-existent. You are not allowed to Work From Home during normal business hours, but are expected to work an additional 10-20 hours a week from home after hours (officially you are supposed to get comp time. In 18 months I received comp time twice). IT Employees are treated as disposable. The attitude prevails that 'we can always hire more.' Contractors are used as stop-gap measures, and rarely are they of good quality (my team was blessed with two good contractors, and a team of 4-5 contractors that developed absolute garbage code). Lots of technical debt and poor architectural design that has not been remedied. Adding in HealthNet has made these issues worse.
