PNC Financial Services Group Customer Service Representative (CSR) interview questions

I applied online for this position and within a week the hiring manager sent me an email to set up an interview. It was a group interview involving about 10-12 interviewees, the hiring manager, and 3 other managers. The interview began with all the interviewees and managers introducing themselves. The managers gave us insights about the company and the position we were interviewing for. Afterwards, the hiring manager asked various customer service questions and everyone took turns giving their answers. Once the questions were done, the interviewees were able to ask the manager questions related to the company and position. This group interview lasted for about 2 hours. I ended up doing well in the group interview and moved on to an one-on-one interview with the branch manager at one of their locations. This was a two part interview. Part one involved the manager asking me questions about my job experiences and what I have contributed to my current and previous jobs. In the second part of the interview, we walked around the grocery store. The purpose of this was to see how well I could interact with strangers and strike up small talk to introduce PNC services and products. This did not go well for me and I did not get the job.
