Deloitte Auditeur interview questions

the interview was going well at the beginning and it was just conversational asking about resumes and behavioral questions but the interviewer asked me a question is how is my tax knowledge being applied to china's income level being low , i was kinda confused on that.

Applied online during recruitment period. Provided as many information as I could to bolster my chances, including previous testimonials and academic awards. A couple weeks later, I was contacted for a group teamwork exercise within the office's meeting space. Group exercise lasted around 40 minutes. I was then interviewed individually by the assessors for reflection on my performance in the group. A formal interview was arranged a few days later, before being accepted for the position.
