PwC Associate Audit interview questions

The first round interview was on campus. I was unable to attend the pre-interview social the night before, which I think hurt my chances of getting an offer. Interview questions were all behavioral ("Tell me about a time when..."). A lot of time was left at the end for me to ask questions. I was interviewed by a tax manager even though I was applying for an audit associate position, which made it difficult to ask questions at the end because my interviewer wasn't as knowledgeable about the audit department.
