When I’m coaching people especially around a career change the subject of the Resume or CV comes up often, and I always ask is your CV on one page?
The response is generally no. Sometimes I see a look that says, do you know who I am and all the things I’ve done? What most people are missing is the point that the CV is not trying to tell a detailed story of your business or vocational career, it is a targeted sales document that will enable you to get to an interview. It doesn’t get you the job itself, for that you need to sell yourself in person.
