1. General rule by level
Junior profiles with limited experience: one page is often best.
More experienced profiles: two pages can work if each block adds useful proof.
2. What stays and what goes
Keep only experience, projects, and skills that support the target role.
- Remove generic task lists without outcomes.
- Merge older low-relevance entries.
- Prioritize strongest measurable results.
3. ATS impact and human readability
Longer resumes are not automatically penalized. The real risk is diluting strong signals.
Your goal is fast readability with clear structure and concrete proof points.
