Pros
A lot of smart, intelligent people work at Humana, specifically the corporate office. Humana provides ample benefits if you don't get sick often, offers tuition reimbursement, and is an overall stable work environment. Also, Mike McCallister is a great CEO and he will be missed when he retires.
Cons
Pay is much lower than industry averages. In order to get big pay increases, you must move around the company to do so. Even then, HR caps the increase (was told no one gets more than 20%), so if you start with the company as I did and they low ball you, you are pretty much going to be under paid at every position. Actually now that I am writing this, it seems most of the problems I have had with this company have boiled down to HR and it's terrible management.
