The engineering educational system in France is quite different from that in English-speaking countries. Engineering schools in France, called Grandes Ecoles d'Ingénieurs, are independent of universities and train top industrial and administrative managers. Ecole Centrale de Lille is one of the top ten French engineering schools.ECL is a multi-disciplinary school which produces future top executives and granted a degree, awarded after five years of post-secondary study and comparable to a Master of Science degree. I am specialized in telecommunications and data analysis. The key subjects were: Math, Computer Science, Energy efficiency, Telecommunications, Project management and Financial analysis.
