I applied through college or university. The process took 2+ months. I interviewed at PwC (San Francisco, NM) in Nov 2014
Interview
I was selected for an on-campus interview for Forensic Consultant but later changed to IT Security Privacy and Risk consultant. These two profiles are similar.
1. Applied on campus. Invited to a dinner party. I went for half an hour but it was not helpful because I did not talk to anyone. I had one drink and left.
2. Interviewed on campus for first round. Mainly behavioral. Asked what I had done before and why forensic consulting. I said I did not know much about this profile so the manager explained. Doesn't hurt to admit that you don't know and you want to learn about it.
3. Within one week I got a call to be interviewed on-site in San Francisco office.
4. Three round of interviews on-site. One case and two Behavioral.
Case was given 2 days prior to the on-site interview. I just glanced through case-in point but it did not help. What helped was understanding the situation, providing solution and backing it up with reasoning.
I had 3 years of work experience so I had some stories to tell. Nothing technical was asked. Basically they want to see if you will fit in their culture.
Got offer within a week. Smooth interview process and great people to work with.
Talk with three persons and one is case interview, the other two are behaviors. People are really nice in PwC and treat you very well. I'm a little bit nervous in my case interview. They give you case 48 hours before your interview and you can prepare for two days. Before the interview, you have about an hour to answer questions and write slides.
