Pros
Work / Life balance at Atos is great. Lots of exciting new technologies and opportunities to learn about and be part of shaping the company through the very low threshold Enterprise Social Network. For instance, Scientific Community (about 100 employees working on the Ascent Journey which focusses on tech 5 years from now), Atos Research Institute (ARI), Olympic Games, Rosetta Space mission. Competence Lines enable employees to meet frequently with peers from a specific discipline. Contracts with clients are usually close to home. Contact with 'the office' happens through ESN, meetings and regular management visits. Training is accessible through a self-learning portal and internally organized courses. Employee Ownership is possible by investing in the Employee Stock plan (no-lose, hedged formula).
Cons
Management sometimes works with short-term goals. In parts of the company, there are complaining employees. You'll have to have the ambition and will to work with and look past that.
