1. The 3 most common reasons
The first reason is wording mismatch: your resume describes similar work but not with the exact language used in the job post.
The second reason is weak evidence: tasks are listed without quantified outcomes or business context.
The third reason is parsing friction (complex layout, unclear sections, key information buried).
2. What to fix first
Take 10 to 15 critical keywords from the posting and place them naturally in your title, summary, and key bullets.
Turn descriptive bullets into proof: action + context + result.
- Target title aligned with the role.
- Core technical skills visible near the top.
- 2 to 3 quantified results in the most relevant experiences.
3. Pre-submit checklist
Before applying, confirm your resume explicitly addresses every major requirement from the posting.
- Target role is explicit.
- Priority keywords are present without stuffing.
- PDF layout is simple and ATS-readable.
