4. Match Onboarding, Training, Implementation keywords: These are the ATS-critical terms for Customer Onboarding Specialist roles. Make sure they appear in both your skills section and at least one bullet point.
5. Tailor to the job description: Run your final resume through the ATS checker against the specific JD. Aim for 70%+ keyword match before submitting.
