Pros
It provided me with experience, albeit very limited in scope, with which to secure a job at a far superior firm.
Cons
Aside from saving his own hide, all my manager cared about was padding his retirement fund. Aside from saving her own hide, all the next most senior employee cared about was obtaining the office manager's job. Training new staff and keeping current staff occupied were unheard of, as younger staff would regularly have only four hours of work during an eight hour work day. Unsurprisingly, there was virtually no mentorship or communication between managers and junior staff. Thanks to the chaos caused by AECOM buying up any small and mid-sized engineering and environmental company they could, a litany of good, talented, hard-working employees left for greener pastures, while AECOM did nothing to better the situation.
