Pros
Three weeks vacation from the time you start, i.e., you don't have to be employed for 5 years or more.
Cons
Everything is a secret regarding salaries. I have asked HR several times to provide the salary range ranges my job title. I also asked in relation to a job submission for a different department. Each time, I received no response from HR, not even an acknowledgement that they received my request. In addition, you never get any type of response to job submissions for internal postings. Even if you are turned down, some sort of communication is better than nothing at all. Another problem is that everything is so compartmentalized that if you are not in a division that cares about what you do, you almost feel like the proverbial red-headed step child. Also, there is usually no training budget depending on the size of the staff at client locations. The money for a region is allocated the same across all schools. Therefore, if you have 10 people at a location, then everyone most likely gets to have training. However, if you are at a location that has 50 or more employees, then you may get training once every 5 years to allow everyone to have a chance.
