PwC Tax Associate

I have asked my friend who worked at PwC for an Audit position referral, however all of the Audit openings are fulfilled by the time. I was contacted two days later by a Tax associate and asked if I'm interested in full-time tax position. The interview process went very well, I was asked to give a more in depth description of what I was doing in my previous job (corporate accounting). Then I was asked three questions with past experience.
1.How is your time management skills?
2.How do you respond to feedback at work?
3.When another colleague is talking about confidential information about another firm, how would you react?

The interviewer also gave a bit more description of how the process will go. And asked If I have any questions to them.
The whole interview took about 20 minutes. Then I received invitation to the next round interview within the same day.
