Well I guess this is an overstatement for the sake of explaining your point and as such it's very effective, but I don't agree with this perspective. The advice tells you to remember that the person hiring you has also put work into that conversation, and that they'll appreciate realizing you have put work into it too. So i think there's an instance of letting our humanity flourish in this, since you're doing an exercise in empathy. There might be too few of these opportunties/spaces left tbh
