I applied online. The process took 1+ week. I interviewed at BT Group (Madrid) in Sep 2014
Interview
I got an email that invited me to an interview with HR. Then, I was contacted to have an interview with my future manager. Finally, HR called me to give the good news that I was selected for the job. The whole process was quick and easy.
