Pros
Safe job: no one is ever fired, for any reason. You can hide in your office in the HQ or in a BU for years without anyone noticing that you are there. Fair balance between family and job commitments. Competence and professionalism are not prerequisites to a good career, yet, if you have no higher education, no talent and no significant experience you can even make a career of it.
Cons
Desert of competence (both technical and managerial) at higher management levels. Autocratic, rude, unprofessional management style. Directors are changed like socks: no coherent and sensible strategies can be developed at any level as a result. Meritocracy is simply non-existent: young "talents" are selected according to their family's political connections. Higher education level in "non-sponsored" employees is seen as a threat rather than as a resource, and punished accordingly. Micro-management in the HQ: plenty of offices and functions in spite of very little job to be done. Proliferation of managerial positions in the HQ as a means to make careers and please political sponsors. On the other end, understaffing of project teams in the BU with massive use of external contractors and work disruption as a result.
