In the world of sales and marketing, employers are most interested in what exactly you have accomplished and if you can create results for them as well!
The most critical aspect of the resume is to specify those results in a concise, accurate, powerful manner. It is important to keep track of performance reviews and any attainable quantifiable data pertaining to meeting/exceeding quotas, strong months or years of sales, enhancing the bottom line through successful programs or campaigns, training and developing other high-performance team members, or anything else which would set you apart from someone else doing the same role.
It is also critical to brand yourself to stand out just like the products and services you represent. Articulate content presented in an aesthetically pleasing manner goes a long way in landing interview requests among highly competitive candidate pools.
