Pros
Individual managers you directly report to can be incredibly understanding and supportive. The work can be interesting.
Cons
It's a managed services company, and sometimes goals are unrealistic. Pressure can be intense. Managers are often promoted through the ranks and might not actually be cut out to manage people - it's highly variable. Sometimes you get unlucky. It tends to be writing intensive and requires attention to detail fr fr, and a lot of people overestimate their abilities.
