The fastest way to get value from ChangeCV is to separate collecting your career history from tailoring each application. Your Master Profile is the place to be complete. Add every meaningful role, project, skill, certification, and achievement there, even if it will not appear on every CV.
Write your experience items as small, reusable pieces of evidence. Instead of keeping one long paragraph for a job, add clear bullets that each explain a responsibility, project, or outcome. This makes it easier to include only the strongest and most relevant work when you create a role-specific CV.
Before creating a CV, read the job description once for the repeated ideas: required skills, problems the team is solving, level of ownership, and tools they mention. Then create a new CV in ChangeCV, choose a target role, and select the experiences, projects, and skills that directly support those ideas.
Use the section order intentionally. For an early-career role, education and projects may deserve more attention. For an experienced role, lead with a concise summary and recent experience. You can make small CV-only wording adjustments in the tailoring step without changing the Master Profile that powers your other applications.
Keep your profile current after each project or milestone, rather than trying to remember everything during a job search. When a new opportunity arrives, you will start with a complete record and spend your time making thoughtful choices instead of rebuilding a resume from a blank page.
