Sales representative Sales representative is my new job title. I work in the company which sells high-tech chemical products. I choose this company because I majored in chemistry when I was at school. I know a lot of chemical knowledge, but sales is another world for me. I don't have any experience regarding sales. It will be a big challenge to me. To open up the foreign market, I need to improve my English very soon. I hope that I can do it very well.
