For the internship, there was an extensive recruiting process, which consisted of going to various speaking/career events held by the firm on campus. Everyone I met during these events were friendly and happy to answer all the questions I had. Through the campus website and the PwC website, we submitted all our information, resume, and cover letter, which was looked at and interviews were given to a portion of the candidates.
There were two rounds of interviews. Since I was in LA, I had a first round interview on the phone with a recruiter, which consisted of mainly behavioral questions, such as why I was interested in that firm, that particular department, and accounting in general. The second round of interviews was in the SF office, the office I applied for, where I was interviewed by three other individuals (manager, director, and partner). This round of interviews were more conversational, allowing them to get to know me as a person, see if I would make a good fit for the group/company, and show me a bit of what their work environment and culture is like.
