Being specific and detailed about your responsibilities and duties can go a long way in getting your CV noticed and shortlisted for the roles that you are looking for! Using the bullet point “admin” doesn’t actually tell a hiring manager what you are actually doing. Are you writing letters, raising sales orders, dealing with customer enquiries, filing, ordering stationary, raising purchase orders, using Sage? All of these duties could fall into general “admin”  but does that word describe what you are actually doing. Try and be detailed and specific! Really think about what you do on a day to day basis in your job and provide that information on your CV.
