PwC Core Assurance Intern interview questions

First got link invitation to Game assessment, several months later got invited to 2v1 30-mins interview, not in HK so the interview was in Skype mode, and two interviewers conducted a 30-minutes interview with all behavioural questions like why Auditing, why Accounting and Finance major, why HK, past internship takeaway etc. offer came after 1 months of the interview

The interview lasts 5/10 mins, where the manager asked me to introduce myself, then answered a series of behavior questions, lastly asked me how to prepare the intern since I have no background knowledge prehend.
