Pros
The people that you work with are awesome. The opportunities for growth and finding your niche` is here. There is something for everyone. You may work in one area, but you volunteer for a NRG (Network Resource Group) to allow you the ability to gain experience and network with others. Also it takes time to really understand your role, and to get adjusted to the way things happen. If you are within Humana, you've been acclimated to the environment, but if you are coming in from an outside organization, just hang around for a year, even when it gets tough, and see what happens. It's a pretty cool place, it grows on ya!
Kontras
Some of the processes are less efficient than one might like. There is a lot of politics and red tape to navigate. It takes time to get used to it. As a PM, there are projects that are pushed through that have little to no business case, that will be made to believe this is a must have, only to find out that it is cancelled a few months later. Sometimes you are asked to manage a project that no one knows what they want, not even the person who requested it. I know it is weird, but it happens. it's a tough role, but if you just hang on, you see that it all works out in the end.
