I applied through a recruiter. The process took 3 weeks. I interviewed at PwC (San Jose, CA) in Oct 2014
Interview
Applied via school Career Center, had a social mixer with the recruiters and staff at the company, and then went in for an OCI and On-site Interview. Recruiter was helpful, you will be surprised about how much information they are willing to share, if you ask nicely. And definitely go to their socials and small mixer, and jog down people's names you met, you can refer to them in interviews, like " yeah, just like when I was talking to xxx, they told me xxx about the company, so I completely agree with you."
I applied in-person. The process took 2 weeks. I interviewed at PwC (Chicago, IL) in Oct 2015

I applied online. The process took 4 weeks. I interviewed at PwC (Sídney) in Apr 2016
Interview
Has group assessment before which involved reading a case study and as a group choosing the best solution. The partner interview was the most relaxed stage, where you are interviewed by two partners in the service line who asked general motivation and behavioural questions.
