I applied in-person. The process took 2 days. I interviewed at Language Campus in Mar 2015
Interview
It was very simple: I made a spanish call to the foreign office manager, telling about myself and why I was calling LC Idiomas (Erasmus Traineeship). It seems he liked my spanish and english skills, so he asked me for the CV. Once sent it, the day after he wrote me back saying LC Idiomas had accepted the application.
