What belongs in your text
Add two to four short points for each job. Explain your work, not only your title. For receptionist, this matters when you answer calls and welcome visitors. Write what you did, where it happened and why the work was useful.
A good example is a short account of how you schedule visits and check details. It shows real work rather than an empty claim. If you have not done that task, choose a different example from your own work.
