The major trick that most CV's miss is; failing to give the employer a reason to hire them. In an interview with the New York Times, Google's chief of people operations Laszol Bock was quoted saying:
"The key is to frame your strengths as: I accomplished X, relative to Y, by doing Z. Most people would write a CV like this: Wrote editorials for The New York Times. Better would be to say: Had 50 op-eds published compared to average of 6 by most op-ed [writers] as a result of providing deep insight into the following area for three years. Most people don't put the right content on their CV's."
The point so many candidates miss is explaining the impact you made during your work experience or past employment on their CV instead of simply what you did.
For instance instead of saying: "I co-ordinated a cricket session for my University development squad. This shows good organisational skills and an ability to manage large groups". You could improve this by saying: "During my position as session co-ordinator for my University cricket development squad I managed to increase participation by 15% week on week by the use of social media advertising. Further to this, I began to organise friendly matches with neighbouring Universities. This gave participants who were looking for a more competitive experience an incentive to continue to develop their skills by coming to sessions, in turn leading to much higher retention rates compared to the previous year."
This technique is called the STAR technique.
By improving your CV and telling the employer what you have achieved you are giving them examples of how you can make effective change within his or her business. This is ultimately why they are going to hire you.
