PwC Tax Associate interview questions

1st round, manager interview; 2nd round, assessment center with a group project observed by 2 managers 3rd round (final), partner interview

Initial on-campus interview. Went well. The interviewer asked four main questions: "can you give me an example of a time you showed leadership?" "Can you give me an example of a time you showed empathy?" Basically just asking you about PwC's core values. Second interview I was called back to the Philadelphia office. I was with three others. Interviewed with one partner and three managers. Interviews went well and I thought I was a contender for a spot. Two weeks past and I got the rejection letter. Heard from the guy that did get the job that he was offered the job a few hours after the interview. I figure they wait-listed me and were just waiting for the guy to accept.
