The process took 1 day. I interviewed at PwC (New York, NY) in Nov 2011
Interview
Got through the first round on campus interview, then they invited me for an office visit, aka "Superday". Start the day around 8:30am, you meet all the interviewees that day, follow by a presentation and a panel discussion (try to ask at least one GOOD question). Then you get assigned to a first year associate that will take you to all your interviews. I interviewed with a manager, a director, and a partner. Everyone was extremely friendly, it was more of a conversation rather than an interview. They want to see if you can hold a decent conversation. Lastly, the first year associate will take you to a group lunch with the other interviewees. I got a call from the partner I interviewed a couple hours later offering me the position.

Interview
I was offered a first round on campus interview with PwC after I applied through my campus career center. The interviewer was really nice and tried to make you feel comfortable. The interviewer initially gives you a brief intro about his/her background before asking you questions. My interview was only 20 minutes, and the only question he asked me was to tell him 3 things about myself. And I had a few minutes left to ask him questions. I didn't receive an offer for second rounds though. I could have failed the interview because I lacked interviewing experience...but the interviewer was definitely not intimidating.

Interview
On-campus interview. Invited to an office interview. There was a prenight social the night before the interview to get to know the other applicants and employees. It was very relaxed and fun. The next day was the office visit/interview. It consisted of an office tour, presentation, three 1:1 interviews (Director, Manager, and Partner), lunch, and a panel discussion. It was relaxed yet serious. It was about getting to know the person across from you though. After the interviews we went to lunch with all of the other applicants and some employees and partners. I was contacted the following monday by a partner congratulating me and he extended an internship offer. HR followed up a few days later with the details.
Advice: be yourself, relax, and have fun
(interviews should be a great/enjoyable experience for both the interviewer and interviewee)
(generally speaking, interviews are not as bad as people make them out to be, you have to come prepared though) (remember: a good resume will get you an interview, but you have to get the job)
