I worked at the headquarters in the glass building in Fort Worth. Somewhere, someone alwasy has food.
Good place to learn lots of technology if you are in the IT department.
Cons
They do not pay people well with the excuse of flight benefits.
A recruiter once told me directors and above have quarterly bonuses. The rest of the crowd is once a year.
They are too much in each other's personal businesses. And you are the outcast if you do not share your personal business.
Vacation is only 2 weeks until you reach 5 years to get some extra days.
Merit increase is a deplorable 2% for the common employees but for management it is market rate.
