Pros
I consistently feel like I work with the best and brightest. The diversity of employee backgrounds brings rich value to project work and to the client. If you need to augment your team's skill set with something else, you will absolutely find it either through your network or resource management. I also consistently feel that the work we do is making an impact.
Cons
The company has changed a great deal since going public a few years ago. Pressures on utilization have increased greatly - the amount of people getting a "lack of work" notice has increased. People are not given adequate credit for all of the extra proposal/BD work they do on top of billable work... the pressure to be billable is higher, yet the expectation to do BD work "in your free time" remains the same. This makes work/life balance challenging at times. Additionally, the higher you are promoted, the more "expensive" you become... which makes it harder to stay billable (you will no longer be considered for certain roles, given your cost as a resource). It seems a strategy to pressure senior leaders to grow their teams, if we are over-hiring then letting people go a few months later. Benefits have changed dramatically for the worse and pay increases are nowhere near what they used to be. The retirement plan and healthcare benefits are MUCH worse than they used to be (albeit still better than many other firms.) You will be lucky if you get a 2% increase, so it does not keep pace with inflation certainly. There are no bonuses. The firm is an extremely political place to work. Your success is highly dependent on having a strong set of advocates and a big network. There are many overlapping "sandboxes," so you must be careful not to anger the wrong group of people.
