Apply online with classic CV + cover letter.
Invited to an interview two weeks after with HR and then interview + case study with a senior manager. Very basic accounting questions. State your motivation and why audit suits you.
Nice staff. Overall process is decent and rather fast (the answer came in the week after the interview).
I applied through my university and received documents to be filled out online two weeks later. First I went through on campus recruiting and I met with a manager from PWC. It was very conversational interview. He asked about teamwork examples like bad team players, how you handled situation.
During the interview, you will find totally three stages. First is a CV screen, then is a AC interview where you will need to finish case in a team , finally there is a partner interview where you have to face a PwC partner and his questions.
