    🌟 Expert Tip
    "Listing tools like Selenium or Cypress in your skills section is helpful; I want to see that. But the strongest automation tester resumes show how those tools made an actual impact. If your test suite cut regression time by 60% or caught a bug that would’ve made it to production, say that. The skill is also in the outcome, not just the tool name." - David Fano, Hiring Expert
