Nobody likes loan officers. They sit in judgment of you. In their hands is the power to decide whether or not you can get finance, and what level of interest you'll pay on that finance if you're eligible for it. Worst of all, they're earning money for every minute they sit there with you, whereas if they decline you you'll walk away from the conversation with none at all!
In their defense, they have to know everything about the loan products they're selling. A degree in business or economics is a 'must-have,' as is certification within the trade and a constantly developing base of knowledge to discern when it is and isn't appropriate to lend out cash. They also need great decision making and problem-solving skills; especially when they have to explain to somebody that they're not going to get the money they've asked for.
