PwC Associate (Audit) interview questions

The interviewer asked me the reason of switching from commercial line to an audit line after 4 years of working experience in commercial line. Besides, he further asked me whether I have been worked in any audit firm before joining commercial field.

Standard Procedures. Online application - Written Test - Accessment Center (both panel & 1:1 interview) - Partner Interview. No technical questions at all. Most of them are fitting questions, and some questions about the company and current issues. My partner Interview lasted for 1 hour and 15 mins, but my friend's is only 20 minutes' long. I guess it depends on the partner & whether they have time to talk with you. The culture is quite friendly and HR sounds nice over phone. But probably because they have too many applications to process, I will not call their recruitment process exactly "efficient". But people there are nice.
