Common Mistakes That Kill Your Chances

Each mistake includes why it hurts, how to fix it, and before/after examples

Missing Trade CertificationsHIGH
Why it hurts
  • Employers can’t verify your qualifications
  • ATS often filters for required licenses
  • Lack of certifications signals inexperience
How to fix
  • Create a dedicated Certifications section near the top
  • List each certification with issuing body and date
  • Include license numbers when applicable
❌ Before

John Doe – Experienced plumber with 5 years of experience

✓ After

John Doe – Licensed Journeyman Plumber (EPA Certified, OSHA 10, License #123456)

ATS Tip
Use exact certification names as keywords (e.g., "EPA Certified Plumber")
Detection Rules
absence of certification keywords
no mention of license numbers
Resumly Tip
Add a Certifications heading and populate it with all relevant trade licenses.
Using Generic Job TitlesMEDIUM
Why it hurts
  • Hiring managers skim for specific roles
  • ATS may miss relevant experience if titles are vague
How to fix
  • Replace generic titles with industry‑standard titles (e.g., "Commercial Pipefitter" instead of "Plumber")
  • Add a brief qualifier that reflects the work environment
❌ Before

Plumber – ABC Construction

✓ After

Commercial Pipefitter – ABC Construction (Industrial Projects)

ATS Tip
Match the job title to the posting’s keywords
Detection Rules
title does not contain keywords like "pipefitter","service plumber"
Resumly Tip
Swap generic titles for the exact role listed in the job ad.
Listing Duties Instead of AchievementsHIGH
Why it hurts
  • Doesn’t demonstrate impact
  • ATS favors quantifiable results
How to fix
  • Turn each duty into a result‑focused bullet
  • Include numbers, percentages, or cost savings
❌ Before

- Installed water lines for residential homes

✓ After

- Installed 120+ residential water lines, reducing leak incidents by 15% and completing projects 10% ahead of schedule

ATS Tip
Start bullets with strong action verbs and embed relevant keywords
Detection Rules
bullets begin with "responsible for" or "duties included"
Resumly Tip
Rewrite each duty bullet to highlight measurable outcomes.
Improper Date FormattingLOW
Why it hurts
  • ATS may fail to parse employment dates
  • Hiring managers can’t quickly assess tenure
How to fix
  • Standardize all dates to MM/YYYY
  • Place dates on the right side of each entry
❌ Before

June 2018 – March 2020

✓ After

06/2018 – 03/2020

ATS Tip
