Transcript

Hello, my name is Mathis Aubert. I'm a Software engineer Co-op at Sopra Steria Lyon since last october.
Currently, I'm working on a major project that impacts the lives of all French people.
Sopra Steria has trusted me on this project because I did my internship in my second year of preparatory cycle.
So yes, Sopra Steria is a Great Place To Work where I'm really happy to work.
They organise agency breakfast where we can find our future mates. Or more, there is the Sopra Steria's tennis tournament at Lyon in June.
