Pros
Flexible work hours. Great people to work with. It's truly amazing that so many talented staff are still at AECOM. As the pointed-headed boss in Dilbert would say, AECOM management likes the employees to be bright, but clueless. Opportunities to work on some great projects with some good clients.
Cons
So much talent wasted on work for an organization whose management doesn't seem to care about the employees, about the clients, about subcontractors, or about ethical business practices. Upper management doesn't seem to care whether the company disintegrates in 6 month or a year, as long as the monthly and quarterly profits look good on the books. Advice to junior staff: don't waste your career working for this organization. Find a better company soon. Advice to people considering employment at AECOM: look elsewhere.
