It is all about sharing their experiences at pwc including overseas secondment opportunities. They will ask you about how you deal with difficult team mates and what you have learnt
I applied online. The process took 2 months. I interviewed at PwC (Hong Kong) in Nov 2016
Interview
Group exercise, 10 people as a big group but subdivide 5 people each to two small groups, read the case and do a presentation
Partner interview, ask CV based questions mostly
I applied through college or university. The process took 3 weeks. I interviewed at PwC (Raleigh, NC) in Sep 2017
Interview
Behavioral interview. They asked you a few questions on your resume and you had the opportunity to ask questions. Approximately 30 minutes. Also, if you are applying for Raleigh audit positions as of this post, good luck. Lots of applicants (Wake Forest, NC State, App State, UNC) all vying for an area with few spots. Go for Charlotte where the odds are better.
