Completed an online personality assessment after applying, around 3 weeks later got an invitation to interview. Received an offer a week later. The interview was one and a half hours long. It was structured as a 45 minute long technical interview and case study, a 10 minute break, then a 45 minute behavioral interview. The technical portion didn't really go too deep into my background beyond a few basic questions about work history and education. Most of the time was allocated to the case study, which they say has no "correct" answer, but rather focuses on your methodology. If you have some coursework or majored in business or information systems, you will definitely have an advantage here. The behavioral interview is what you'd expect from it, the usual "tell me about yourself" routine. The interviewer said to treat it as a conversation. They're trying to get a gauge on how well you can communicate and present yourself, since PwC plans to stick you in front of clients.
