Executive CVs differ from other CVs, as the whole CV should focus on quantifiable achievements. The CV should not only be aimed at stressing your unique selling points, but should remain audience-focused, whilst communicating that you understand the employer’s requirements and that you are qualified to meet those expectations.
Demonstrating to an employer what you did and what you achieved in each position is far more important than the scope of your responsibilities. Concentrate on clearly specifying: what you did, accomplishments and results achieved. Try to provide quantifiable evidence where possible when backing up your points.
