Pros

Organization's reputation Provided equipment and facilities Flexibility (home office / remote work) Multicultural environment

Cons

Lack of staffing/human resources to meet objectives, which generates intense pressure on the teams (risk of burnout and decreased overall satisfaction, sometimes evident in internal feedback). Top-down management culture that does not always foster transparency or the reporting of concerns. Heavy bureaucracy that sometimes overrides business common sense. Disconnect between internal communication/management slogans and the daily reality of operational teams (particularly regarding the perceived stability of the teams).
