The goal of this school and by extension of 42 (the school mentioned in the OP link) is to create real hackers, people able to learn by themselves. Most of the projects are coding projects right but it's oriented in a way that forces you to learn all along the way if you want to succeed. Learn from internet, books or your peers. RTFM is the motto of the school.
You'd be surprised by what the students are able to achieve.
If that matters some Epitech students work in very successful companies (fb, twitter, google or microsoft) and the Docker founders were in Epitech.
