Hard vs Soft Skills Recruiters Filter For

Writing a Resume Summary That Survives Screening

Open with your license level and state in the very first clause — ATS at mechanical contractors and service companies filter on 'Journeyman' or 'Master Plumber' before a human ever reads the file. Follow immediately with your specialty (residential service, commercial new construction, hydronic systems, etc.) and one quantified proof point such as first-visit resolution rate, weekly call volume, or inspection pass rate. Name specific systems and codes you work under (IPC, IAPMO, UPC, CALGREEN) rather than generic phrases like 'code compliant,' since ATS parsers match literal strings. Keep the summary to two to three sentences and save soft-skill language for the experience bullets where it can be backed by numbers.

Mistakes That Get Resumes Auto-Rejected

These mistakes show up most often in Plumber resumes that get downranked or filtered out before a recruiter ever sees them.

• 1

  Omitting the state name from the license credential (e.g., writing 'Journeyman Plumber' instead of 'Texas Journeyman Plumber License') causes ATS string-matching to miss the required license filter entirely.

• 2

  Listing pipe materials generically as 'various piping systems' instead of specifying 'PEX-A, PEX-B, copper, PVC, CPVC, cast iron' — ATS parsers at commercial mechanical contractors match literal material names, not umbrella terms.

• 3

  Failing to include ServiceTitan (or the specific FSM platform used) anywhere on the resume, which causes automatic downranking at service companies that list it as a required or preferred tool in the job posting.

• 4

  Burying the license and certifications section at the bottom of the resume instead of placing it in the header or immediately after the summary, causing human reviewers who scan for 7 seconds to miss the most critical qualifying credential.

• 5

  Writing experience bullets as duty lists ('Installed pipes, repaired fixtures') rather than outcome statements with metrics, which scores poorly in AI-assisted screening tools that weight quantified impact over task description.

• 6

  Keyword-stuffing the skills section with every plumbing term imaginable (including systems never actually used) — modern ATS platforms flag density anomalies and AI screeners on Workday and iCIMS cross-reference claimed skills against job tenure and context in the experience section.

• 7

  Leaving out specialty certifications such as OSHA 30, ABPA Backflow Prevention Assembly Tester, or tankless water heater manufacturer training (Navien, Rinnai) that commercial and service employers increasingly use as hard filters before routing resumes to a hiring manager.
