I applied through my school career center. I Interviewed on campus and a couple of days later I was informed that I was invited to their office interview. A month later I interviewed at their office in Manhattan with a partner and a senior manager. i was asked pretty basic questions, the partner was more easy going, he wanted to see my soft skills more than anything. On the other hand the manager asked me some audit questions which through me off a bit but I managed to answer.
