Me postulé a través de otra fuente. El proceso tomó 2 meses. Acudí a una entrevista en GitHub en mar 2013
Entrevista
light weight phone screen - a bit of tech, a bit of personal chat.
then they will ask you to write some code (patch an existing project, etc - something relatively relavant to the job ) and publish it on github.
then they'll just ignore you. good luck!
