Colloquio
They ask you for a data challenge and they give you two weeks to prepare it (because they think you have to invest at least two weekends to solve it). I just invest two days because I was in other selection processes (people have to understand that are you given your free time and it is not infinite), although I sent a pretty complete solution. Not feedback at all. A complete lost of time.
