Pros
There were very little pros to working at AECOM except for the people. Most of the "worker bees" were good, intelligent people. Before AECOM purchased URS, it was marginally better but as soon as the acquisition took place, it all went rapidly downhill. The only real pro, if you like to travel, was the opportunity to travel abroad for work.
Cons
Too much work overload and burn out, too little guidance from management. Horrible salaries for the hours being put in and subpar benefits. Every chance they got, the reduced any meager benefits we still had. There was little to no work/life balance. You were expected to work into the wee hours of the night as the rule, not the exception. Weekends were also frequently required. There was little emphasis put on quality of work. It was all about the quantity. The idea of internal customer support was non-existent.
