What Hiring Managers Look For

Hiring managers look for administrative assistants who are organized, proactive, and reliable. But 'organized and detail-oriented' on a resume is meaningless without proof. Show it through metrics: 'Managed calendars for 5 executives, coordinating 40+ meetings per week with zero scheduling conflicts' demonstrates the skill rather than just claiming it. Highlight the scope of your support. How many people or departments did you support? What was the size of the office? What budget did you manage for supplies or events? Scale matters — supporting a C-suite of 4 in a 300-person company is different from answering phones at a 10-person office. Show technology proficiency. Modern administrative roles require comfort with Microsoft 365, Google Workspace, Slack, Zoom, project management tools (Asana, Monday.com), and expense management software (Concur, Expensify). List specific tools rather than generic 'computer skills.' Demonstrate initiative and process improvement. The best administrative assistants don't just maintain systems — they improve them. If you streamlined a filing system, automated a manual process, negotiated better vendor rates, or created templates that saved time, those achievements set you apart. ATS keywords include 'Microsoft Office', 'calendar management', 'travel coordination', 'expense reporting', 'executive support', and 'office management.'
