In your Experience section, always strive to describe your background in terms of results. Doing so will put you light years ahead of your competitors, who usually will only offer what amounts to position descriptions of their experience. Job descriptions are boring to write and even more boring to read, and thus, they are quickly forgotten. Describing your experience in terms of results is the gold standard here. They include specifics― details that stick in one’s mind. Employers are much more interested in results than they are in process.
Achievements make for both a livelier document and a much more compelling reason for any employer to keep you in the game. This also forces you to think in outcome-oriented terms, which will help you both reconstruct your history and boost your self-confidence, as well as put you in the proper mindset for communicating with prospective references, contacts and employers.
Again, the point here is to do something different.
