KPMG Auditing Associate interview questions

I had three interviews. The first was very good and everything was perfect. The second was terrible, since the interviewer tried to let me feel ignorant or that i chose the wrong university. I answered every question, and at the end he told me that i had to choose more specific areas, instead to follow my curiosity: I think this is totally unpolite. The third interview was normal, with a partner of the firm.

I was previously interns in the company. I got offer after my internship end. Hence, I didn't really gone through interview except for internship interview by Human Resource team.
