General ATS Best Practices
Frequently asked: Aon resume & hiring
What ATS does Aon use?+
Aon uses iCIMS as its applicant tracking system, verified against their live careers portal. iCIMS parses your resume, extracts your contact info, work history, and skills, then ranks your application against the job description's required keywords. Resumes scoring below a 70–80% keyword match are typically filtered out before a recruiter ever sees them.
What keywords help a resume pass Aon's ATS?+
For Insurance roles at Aon, the strongest resumes include keywords like Underwriting, Actuarial, Claims, Risk Management, Compliance, Policy Administration. The single most reliable source of keywords is the specific job posting you're applying to — mirror the exact phrasing (skills, tools, certifications, and outcome verbs) in your Skills section and inside your bullets.
What format should my Aon resume be in?+
Submit a clean, single-column, text-based PDF for Aon. iCIMS parses this format most reliably. Avoid tables, multi-column layouts, images, icons, headers/footers, and decorative fonts — all are known to break ATS parsing. Use standard section names (Experience, Education, Skills) and a font like Arial, Calibri, or Helvetica at 10–12 pt.
How long does it take to hear back from Aon?+
Most candidates hear back within 1–3 weeks of submitting an application to Aon. Resumes that score 80+ on the ATS keyword match are surfaced to a recruiter within the first 48 hours. If your resume is below 70%, it may never reach a human — run a free ATS score check first to see where you stand before you apply.
Does Aon use Workday?+
