Pros
AECOM is largest engineering design firm in the world. With that title comes opportunities to work on projects that smaller firms cant touch. Benefits are OK but would expect better for company of this size. Talented people remain in some offices but many have left or been laid off.
Cons
A revolving door of senior managers and other leaders in the company. No long term vision, business decisions are based on making next quarter numbers because public traded. The company makes rash misguided decisions regarding staff layoffs just to meet numbers to please investors. When you throw 30 company cultures into a cage what you get is AECOM chaos. Integration of legacy companies has not gone smoothly there is still internal backstabbing, no collaboration and mistrust between managers and staff of legacy companies.
