Three calls: A first screening call from a person from Human Resources, a second with the managers in Europe and a third technical final one with the team for Madrid/Spain. There were three tests about coding: One about how to develop a couple of functions (Hint: Linq), another about a class which could compile, but it would return errors in execution time and the third one was some of that kind of Google interview questions. I didn't get an offer because of my catastrophic performance ;-)
