Pros
Applied research within Paris Saclay campus area. Many different industrial partners and projects opportunity to apply computer science techniques and get contact in industry and academia. Let you make research and publish paper as in academic area but priority must be put on your industrial project success. Possibility for patenting before publishing, with some financial reward. 50 days of holidays and social and leisure services à la française. Very nice colleagues
Cons
Do not come if academic research is your main objective. Human resource management is a chaotic rule-of-thumb process. Main financial resources coming form industrial partnership with lot of engineering requirement (project management, computer programing) but without the salary of R&D in industry Do not expect reward and financial compensation for your suplementary efforts, so you are not encouraged to surpass yourself to make the all business better.
