RBC Customer Service Representative (CSR) interview questions

RBC had a campus hiring event at my university, so I sent my resume directly to hr, then I was informed that I had a group interview with other 8 (approx.) candidates after 3 weeks. The interview took about an hour and a half. Four rounds in total, and most of the activities needed to work with another candidate. One round was to sell a product, which was chosen in bunch of some random things to the hiring crew.
