It was a very interesting, useful and exciting experience. Each stage of the program, without exception, was very useful for my professional and personal development. The structure of an argument, the development of strategies, the "problem tree", the ability to carry out and develop surveys, and of course the art of debating were thoroughly and at the same time clearly explained by Challenger mentors. It was, without exaggeration, a very useful time for me, due to the knowledge gained and the pleasant and friendly Challenger team, as well as the guys who participated in the program with me. It was more than worth it!
