PwC Associate Risk Assurance interview questions

I was referred to a recruiter by a friend and was offered an interview. I got a Skype call from a Partner; the interview felt informal and laid back. It lasted less than 30 minutes. I got a rejection email two weeks later.

PwC had visited my campus. I had 3 on site interviews, two with the directors and one with the partner. Most of them were behavioral questions and wanted to know more about my previous work experience.
