Two interview in Spanish, one on the phone, second on internet with camera. Questions regarding your career objectives, what success you have done, your personality, how international you are etc. They were underlining they are not offering a position but an international career with this program. They are trying to make sure you are also looking for this position with your long term ambitions, not only for short term position. Excellent Spanish is required as my Spanish is good and enough to conduct an hour interview, they told me it is not as fluent as they require.
