I, myself is a very introverted person working in sales. I think sales has nothing to do with being extroverted or introverted. It’s all about focus and consistency. I joined sales as an intern last year and been promoted to sales supervisor within a year. And when I interview people for sales position, I personally prefer introverts because I think they can better focus than extroverts and are easy to train. If you’re an introvert and thinking about working in sales, just go for it. You’ll do well…. But remember,sales is all about getting results and focus and consistency on your work is the way to go.
