It wasn't any different from the other Big4 firms. First a math, a logic and an English test, all of them in a written form. None of them were harder then average, but it is advisable to take them first at the last desireable Big4 for practice. (For the math a calculater was permitted.) A usual HR interview couple of days later, about my studies, achievemets, goals. Another interview with an Auditor Manager, about work/finance related questions. Finally, a partner interview in English, which was a bit of a mix of the previous two interviews. But mainly about my future goals. Overall it took me about 1,5 weeks, but since I had interviewed at Deloitte, PwC, KPMG as well, I was able to find a better fit for my expectations. For outsiders there are minor differences; any one of the firms is a perfect choice for an "auditor-wannabe".
