There is little or no opportunity for promotion beyond the VP level. Executive level politics are horrible, and although they talk about a "meritocracy", it's just a sound bite. Promotions are awarded more like a beauty contest than based on performance.
Compensation is below average. If you stay longer than 3 years you get left behind on your compensation and they hire new people in at much higher salary levels. Also, the disparity in pay between the Senior Leadership Team and the rest of the company is HUGE.
Benefits package is expensive and keeps getting more expensive every year as the company pushes more of the cost down to the employees.
