A resume summary is three lines at the top of the page that answer one question: why should this recruiter keep reading? Get it wrong and the rest of the resume never gets read.
The formula: [role + years] + [domain or industry] + [one quantified win] + [what you want next]. Every strong summary in this list follows it.
Fresher example: 'Computer science graduate with two internships in backend development. Built and shipped a Django API serving 12,000 monthly requests. Looking for a junior backend role in a product team.'
Mid-level example: 'Product manager with 5 years in B2B SaaS. Led a pricing revamp that lifted ARR 23% in two quarters. Seeking a senior PM role owning a full revenue surface.'
Senior example: 'Engineering leader with 11 years across fintech and payments, managing teams of 20+. Cut deployment lead time from 9 days to 4 hours. Looking for a director role in a scaling infrastructure org.'
Career switcher example: 'Teacher turning to instructional design, with 6 years building curricula for 400+ students and a completed UX certification. Seeking an L&D role where content and learner data meet.'
What kills a summary: adjectives with no evidence. 'Hardworking, passionate, detail-oriented team player' says nothing a recruiter can verify. Replace each adjective with a number.
Rewrite your summary per application. The last clause — what you want next — should echo the job title in the posting. DraftlyCV's style presets can regenerate all 25 variations of yours in seconds so you can pick the one that fits the role.
