Pros
Suits Gen X and Gen Y. If you aren't good at engineering you can always become a group leader, corporate risk officer or regional director. If you can get a management position at this company then you will be set for life.
Cons
Too many to mention. The takeover by AECOM, multiple acquisitions, and rabid hiring has resulted in destruction of what was once a good engineering consultancy in Australia. The culture has totally changed and become unfriendly, competitive and polarised. The group I was in increased in size from 7 to 37 in two years by hiring of incompetent idiots and inexperienced, arrogant graduates. Proposals were submitted to clients stating that senior people would be working on the project. When the project was won the inexperienced graduates would be assigned the work in order to justify the group leader's hiring decisions and increase profits. Senior people were left with no work and then attacked and threatened by the group leader for having low billability. At the same time, senior staff were also expected to train the graduates by running courses for them at lunchtime (i.e., their own personal time). The work environment was very stressful with constant threat of layoff and insufficient work, yet the leader simultaneously kept hiring more people to "grow the business". It made no sense but clearly he was on a mission to meet some personal target. This company has many other serious problems and fails to recognise that it is too big for its own good.
