Internal Auditor Resume Tips

What recruiters look for, keywords that get past ATS, and what skills to highlight in 2026.

A Day in the Life

An Internal Auditor typically starts the day reviewing audit workpapers and updating risk control matrices for an ongoing operational audit, coordinating with process owners to gather evidence and resolve open items. Midday may involve walking through a controls testing procedure—sampling transactions in the ERP system, reconciling GL entries, or interviewing department heads about segregation of duties gaps. The afternoon often shifts to drafting findings in audit management software, prioritizing observations by risk rating, and preparing status updates for the Chief Audit Executive ahead of the audit committee report.
