Pros
You will probably like the employees in your department, most are very good people. If you start working at OU straight from college, you might enjoy an extra year or more of living like a student while having a real, if small, paycheck. Beautiful campus, nice town, excellent recreation.
Cons
The other reviews on glassdoor are mostly accurate, with common themes that echo my own experiences - limited room for advancement, dysfunctional leadership, a caustic environment in finance, decisions by accounting, and passive-aggressive power struggles. Advancement often feels less like a competitive process and more like a beauty pageant. You will experience extreme resistance to change even though everyone knows that change is needed in other departments. Occasionally the place tries to change and brings in a new group of executives to do this. The new executives either stay stay for many years until finally asked to leave or move on after a couple years to a top-tier university. Don't expect much from new leadership. Pay raises tend to match increases in the pay structure, so after spending years of experience learning to do your job really well, you will only earn slightly more than new employees with zero experience.
