Pros
The upside of working at AECOM is that once you leave the company, you will be a much happier person and your next job will seem perfect since your experience at AECOM was a complete circus act.
Cons
Amazing things DO NOT happen at AECOM. It's the complete opposite in fact. Facts: The company is one of the worst companies to work for. It's so bad that Carol Walton wrote about AECOM in her book "Worst Companies to Work For." AECOM is managed by accountants. Mike Burke used to be a partner at KPMG but was booted. Unfortunately, he made his way over to AECOM and is now in charge of running an engineering company. And to top it off, he recruited Steve Kadenacy to be President and COO of AECOM, who is a big bully and rules by fear (good job Stevie!) Well you know how this story will end.... Benefits are laughable. You better not get sick because you will be paying more for your healthcare than what you earn at this company.
