Applied online and got a referral from a manager from a different office. Wasn't able to go through campus recruiting due to college being outside US, so it involved following up with a lot of recruiters. Had a preliminary phone screening, which was essentially to make sure you weren't a total freak. Basic questions about yourself, interest in accounting, and mostly just walking through your resume. Had I think 2 other similar screenings as follow ups (it seemed like I was getting passed around recruiters for a bit repeating the same step in the interview process). Was informed of an in person interview at the office the following month. Met with a partner and a manager. Both interviews focused on my resume and interest in the position/accounting. Not many difficult questions (none really that I hadn't prepared for: why PwC, why audit etc.). It felt like they were trying to get more of a feel of your fit with the company rather than your qualifications and whether you would last or not. Both interviews ended up as more of a conversation about my travels etc. Got a call the next day from the partner I interviewed with and my main recruiter that I was offered the job.

lot of stages of interview. i need to take a test. then go through the first stage of interview. then 2nd interview is quite tough as they the questions are more very high thinking level which i am underprepared. but it was a great experience.
