Most people do not think in the terms of quantified achievements when they are in their position at work, but on the resume, that is the ONLY part that matters to the hiring manager.
For example if you only state:
- Managed all recruitment activities for a Financial Staffing Division. This is only a job responsibility.
- Instead state : Responsible for growing staffing revenue as Manager from a -14% profitability to a +12% revenue profitability in two months through internal team building and development of strong external business relations with financial hiring managers.
- Then in the next sentence you could state exactly how you developed these relations.
