Pros
A good on boarding program for new hires straight out of school (not so much for lateral hires). Good training facility in France. Bright consultants who care about their work and their teams. Nice collaborative culture depending on your office. You learn lot of good core consulting skills in your first years ... provided you can get staffed ... and depends on your project manager. You can learn a lot if you look for opportunities and people get to know you.
Kontras
Inconsistent culture between offices. Favoritism from VPs. Though they say there are clear guidelines for raises and promotions, they are ambiguous and not consistent - lot is based on favoritism. VPs will sell anything just to get the work even if there are no people qualified to deliver ... and then the consultants suffer from under-resourced projects. A lot of mediocre managers and senior leaders - causes people to leave. Not a lot of diversity.
