Your resume is for experience and accomplishments only. It's not the place for subjective traits, like "great leadership skills" or "creative innovator, says Alison Green in U.S.News & World Report.
You should always try to quantify your accomplishments.
Suzanne Lucas at CBS Moneywatch writes:
"Some departments have 1 person, and some have 350. Quantify yours. "Managed a department of 12 analysts" is a lot stronger than "Managed a department." Did you have budget responsibilities? "Managed a $2.3 Million budget" is very different from "Managed a $75,000 budget." How many clients did you juggle? 1, 2, 25? Quantify."
If you can't put a number on what you've done, try linking the impact of your projects to the company's "point of sales."
For example, if you were in charge of creating a marketing campaign on Facebook, show that you were able to reach the company's target market without having to spend the money that is usually spent on advertising.
"Basically, if you can't prove that you have sales, you can prove that you saved the company money by reducing marketing expenses," Roderick Lewis, international relations director, ISCTE Business School, University Institute of Lisbon, tells us.
