Read first

  1. Vulnerabilities found and fixed, by severity
  2. Controls or tooling you built
  3. Compliance work and your part
  4. Current certifications

One line, before and after

  • Original: Ran quarterly penetration tests on the web app. Found 14 high severity issues in 2025 and worked with teams to fix all of them within 30 days.Suggested: Found 14 high severity issues in 2025 penetration tests of the web app and worked with teams to fix all of them within 30 days.
Why this changedFindings and fix time lead; the test cadence is context. Every figure in the rewrite is in the original line; nothing is added.

Mistakes that cost interviews

  • Naming tools without findings
  • Sensitive details about past employers
  • A wall of technologies with no context
  • Team achievements written as personal ones
  • Seniority words the resume does not support

Evidence that counts in software engineering

  • Systems or features worked on, and the candidate's part in them
  • Scale: users, requests, data volume, latency, cost
  • Measured effect on reliability, performance or cost
  • Stack named where it was used, not only in a skills list
  • Code review, mentoring and design work for senior roles
  • Shipped side projects or open source for early careers

Use what your resume already shows. A line without a number can still be strong when it says clearly what you did and where.
