Pros
The office is in Paris, and the projects are interesting and impactful. Like for any consulting firm, it is a good school of business, with the benefit of being a creative work environment.
Cons
Because of the no work-life balance culture, you never actually get to enjoy the city (talk about a french way of life!)... too much of the company's communication is based on "poudre aux yeux", they try way too much to be the cool kids in town, when they are actually not. The management is distant and snob, unless you have the same background as them, or unless you are of incredible personal value to them (if you have an outstanding alumni network): they play favorites, and not in a good way. Like all french, they are obsessed with the "grandes écoles" system, and it leaves other employees out of the loop.
