The single most common mistake in job applications is misunderstanding the purpose of a CV. It is not an archive of everything you have ever done. It is a marketing document designed to sell one specific thing: an interview.
The Landing Page Mindset
Think of your CV as a sales landing page. A visitor (the recruiter) arrives with a specific problem (an open role). They have a limited attention span. If they dont see a solution within the first few seconds, they bounce.
"Responsible for managing the company's social media accounts and posting content."
"Grew LinkedIn following from 1.2K to 18K in 9 months by launching a weekly thought-leadership series."
Focus on Outcomes, Not Tasks
Recruiters dont hire for responsibilities; they hire for results. Every bullet point on your CV should answer the question: "So what?" If you "managed a team," tell us how that team performed under your leadership. If you "wrote code," tell us what that code solved.
