Pros
Great learning experience, good pay and benefits. Chance to work on the biggest most challenging projects in the world. If you do not understand controls (financial, process, projects etc.) after working for EM you will never understand. They are getting rid of some of the good ol boys but not quit fast enough.
Kontras
Yearly ranking session not based on performance. You can have an exceeds yearly performance review and your ranking can still go down if you do not have the right sponsor or older than 55. Currently company is downsizing by weeding out 55 years and older and replacing with younger less experienced. Most folks hate the ranking session and what it does to the team work environment... kills the incentive to work in teams with those in your rank group. EM is talking about changing the environment and being more team oriented but they refuse to change the yearly forced ranking which puts fear and mistrust in everyone.
