I applied for the full time position of Tax Associate through the campus website and got invited for on-campus interview. The interviewer was a director at PwC and the process was very smooth. The questions consisted of typical behavioral questions (no technical questions) such as tell me about yourself, tell me about a time when..., why did you choose tax, etc. I got a phone call two weeks later for a second round interview and I haven't gone through it yet, so wish me luck!! But the second round consists of a pre-night dinner with staff which is a little bit informal to break the ice. Then for the actual interview, you are invited to the office you have applied for. The interview typically consists of three 30-minute interviews with two partners and one director. There will be behavioral questions but it is more conversational type, they merely want to see if you are a good fit for their firm. There will be an office tour and probably a presentation on the company conducted by a recruiter. You will also get introduced to staff (associates, partners, directors, and etc.), so you will have lots of opportunities to ask questions, network, and see if the company is a good fit for you.
