Pros
One of the few companies giving truly global and grand scale experience in all avenues. Truly great people to work with. Best place to learn to think big and aspire to big things. Fantastic place to try different jobs and expand your career opportunities. You can literally have multiple careers ranging from engineering to architecture, to marketing, sales, etc.
Cons
Government-like bureucracy throughout the company. Most risk averse environment I could ever imagine. No actionable interest in innovation from management team. Strong 'blame' culture in face of failure. No useful communication from executive leadership to their employees. Absolutely no avenues of advancement to executive level; all execs are hired from outside. All real decisions come from external consulting teams.
