Use job language honestly
Identify tools, responsibilities and outcomes in the vacancy. Include them only when they describe experience you can support with evidence.
Make extraction predictable
Use familiar section headings, keep dates near roles and avoid using graphics as the only source of important information.
Treat scores as review signals
An ATS score can identify missing context or formatting risks, but it cannot guarantee an interview. Correct the issues and then reread the CV as a person would.
