03 — PARSING MECHANICS

How Enterprise Systems Scan Security Engineer Applications

Deterministic Keyword Matching

Most platforms (Greenhouse, Workday, Lever) use rule-based token and stem matching. Phrases like "Reading Comprehension" are matched directly against candidate text. They do not guess or infer unstated proficiencies.

Contextual Proof (Google XYZ)

Keywords isolated in a comma-separated list carry less weight with recruiters than keywords integrated into accomplishments: "Accomplished [X] as measured by [Y], by doing [Z]".

Zero-Fabrication Standard

Never fabricate metrics or invent qualifications to force a 100% match score. Where your history lacks a numeric metric, state business outcomes and scope truthfully.
