The three-line formula
Line one is identity: job title, years, specialism. Line two is proof: your strongest quantified achievement. Line three, if used, is direction: the kind of role you want next. That is the entire structure.
Write the summary last. It is a distillation of the bullets underneath it, and trying to write it first produces the vague filler most resumes open with.
- Name the job title you are applying for, not the one on your last payslip
- Include one number in the first three lines — any number beats none
- Use plain present-tense language, not third-person narration
- Rewrite it for each application; it takes two minutes and changes the match
