Monument (UK) interview questions

I went through a telephone interview first where there were basic questions and where I had to ensure the interviewer was interested in me and was then invited to a Teams interview where it was an hour long

Initial HR Screening Interview with line manager and a young individual from a different team. Both were friends previously at a different firm, as it appears most people are here. First 10 minutes was wasted by the manager trying to explain the company and role With less than 10 minutes to go they poorly described a scenario for which you have to instantly answer. Unsure how this can be deemed effective when those describing it don’t appear to understand it themselves. I asked multiple questions about the business including some about interest rates. I would expect the manager to be able to clearly articulate commercial answers but they appeared to have no answer, despite being very close to the subject in their day to day. No feedback or response of any kind after wasting an hour of your time.
