I wonder whether the lack of clarity in this video is bug out feature.
Rewatching, I think that he uses his DQ skills to try and enhance his communication with customers, rather than that he comes to work in DQ. That said, his communication skills need improving: I don't think 'methodical' was the word he was looking for. Interactions with a financial institution need to be methodical. It is crucial. But they can certainly be more human, more personal.
As for the target demographic, perhaps we are not it. Perhaps they are trying to reach beyond their largest demographics and specifically attract TQ+ people (feature turned into bug).
Financial institutions don't just deal with finance. They do engage in social engineering. That's exactly the original purpose of building societies. They were set up to enable people who were not already wealthy to obtain mortgages and buy their own homes.
