Paid employment is one source of experience, not the only one. A school project, a club responsibility, caring for someone, volunteering, or organizing an event can show how you approach real tasks. The useful question is what you personally did, rather than how impressive the activity sounds.
Pick one example and write down the situation, your actions, and what happened afterward. If the outcome was not measured, say so. AI can help make the explanation clearer, but it should not invent a title, responsibility, or achievement that you did not earn.
