PwC Auditor interview questions

So I got an interview with Pwc through my university by going to networking events and talking with recruiters. They called me in for an on campus 1 on 1 interview, and if they liked me they would call me in for an in-office interview, which I think was going to consist of 3 interviews with different managers. The lady i interviewed with was very nice and I met her a few days before at a dinner we had with Pwc, so I was somewhat acquainted with her. My interview was toward the end of the day after she had numerous other interviews, and I immediately got the sense that she was pretty over interviewing/ or has found the candidate she was looking for and no longer had a need to fill the position. She didn't really ask me any questions, she just chit-chatted for a while and I asked her more questions throughout the interview than she asked me. It was a very weird interview because it didn't contain any behavioral type questions the big 4 usually asks, and I had to really try to show skills and qualifications I had without it being awkward since she wasn't asking me any relevant questions. It was a very friendly conversation and I almost felt good after the interview because we had a nice conversation even though she didn't ask me any questions, so I kind of assumed she liked me. However, I did not get called back for 2nd interviews so I guess it wasn't the case. I'm pretty sure this isn't a very indicative interview of pwc since the one I had with Deloitte was much harder and had a lot of behavioral type questions which I imagine is what most Pwc interviews are like.
