Start with the job you want, not the job you had
The easiest way to make job history feel relevant is to decide what the next employer needs to believe. Before you edit the section, open the advert, job description, or person specification and mark the responsibilities that keep appearing.
Look for repeated themes such as customer handling, stakeholder management, stock control, analysis, coding, safeguarding, sales targets, shift leadership, project delivery, complaints, reporting, budget ownership, compliance, or patient care. These are your selection filters.
Then ask one question for each past role: what can this job prove for the next one?
A supermarket role might prove customer service, cash handling, stock accuracy, and working under pressure. A university society role might prove planning, communication, budgeting, or event coordination. A short placement might prove that you understand a sector and can apply technical knowledge in a workplace.
Do not describe every role as if every detail has equal value. A CV is a selected argument, not a complete record.
