I am a current QEM student. To be honest, it is a okay program (If you choose Paris and Barcelona as your mobility. Dont go to germany or venice) but if you are interested in going for a PhD, Tinbergen will land you in better schools than QEM can. If you choose QEM, the only option is to go to PSE-ETE for your 2nd year, which will guarantee you a t15 PhD in the US. For industry, QEM is the worst you could join.
