I got to experience the new "Pwc Professional" interview. Basically its supposed to standardize the interview process. The major difference is that all the interviewers take a lot of notes. During first rounds got a "what if" question: What would you do if your saw an associate disclose confidential client information to another employee.
The second round was unique because a LOT of behavioral questions were asked anywhere from 4 to 6 per interviewer. Don't expect a conversational interview, be prepared and know the PwC professional attributes and a story about yourself that will fit each one. 3 interviews 45 min each, with 5 to 10 minutes for questions (the rest is you talking about yourself so be ready!)
