hi @mekkaokereke@hachyderm.io , your interviewer wasn't well informed on this. In Spain universities are not free. There are public unis (price is partially subsidized) and private ones (more expensive). Ypur point still holds for me in that student debt is not a thing here, but I think that the question being based on wrong info, erodes a bit the answer.
thanks for boosting the thread! I missed it first time.
