I worked for more than 6 years in the BPO industry and over 3 years as a freelancer and handled mostly sales accounts. I started as a technical support (with non-profit sales) representative then eventually decided to work at home as a freelancer.
I am aggressive in terms of closing sales and setting up appointments to ensure that I achieve the goal I set for myself. Sales is all about having a good understanding of what the product is and highlighting its benefits and simply convincing customers the "WIIFM" of the product you're selling.
