The Skills You Forgot to Put on Your Resume (and How to Find Them)

The biggest gap on many resumes isn’t a missing job — it’s the everyday skills you stopped noticing because they became second nature. A machinist who reads GD&T, runs SPC checks, and holds tolerances all day often writes “operated machines.” That undersells years of real capability. Here’s how to find what you left off — honestly.

Routine work hides your best skills

When something becomes automatic, you stop listing it. But the reader doesn’t know you do it unless you say so. The goal isn’t to pad — it’s to name the real things you already do that you’ve gone blind to.

Walk through a normal shift

Go hour by hour through a typical day and write down every distinct thing you handle: tools, software, standards, safety procedures, inspections, paperwork, the people you coordinate with. Many people find skills they’d never have listed from memory.

Name the standards, not just the tasks

The standards a job runs under are often the most valuable keywords — and the easiest to forget:

• Quality / manufacturing: SPC, GD&T, Gauge R&R, IATF 16949, ISO 9001
• Electrical / trades: NEC, OSHA 30, Lockout/Tagout, arc-flash
• Healthcare-adjacent: CLIA, HIPAA awareness, BLS

Only list a standard you genuinely worked under — and distinguish “worked to this standard” from “hold this certification.”

Capture the tools and software

Equipment, machines, control systems, and the software you touch (even the boring ERP or scheduling system) are all legitimate, searchable skills.

The best skills to put on a resume, by trade

The skills to put on a resume are the ones you can demonstrate on day one — here’s where they hide, role by role:

• Machinists / CNC: setup vs. operate (say which), the controls you run (Fanuc, Haas, Mazak), print reading, GD&T, in-process inspection, the measuring tools you use daily (micrometers, calipers, CMM).
• Electricians / maintenance: the systems you troubleshoot (PLC brands count), preventive-maintenance scheduling, conduit bending, panel work, the voltage classes you’re comfortable in.
• Warehouse / logistics: the equipment you’re trained and evaluated on (forklift, order picker, reach truck — under OSHA’s 29 CFR 1910.178), RF scanners, WMS software by name, cycle counting, loading-dock safety.
• Drivers / operators: endorsements and card types by name, ELD systems, pre-trip inspection routines, load securement, hazmat awareness.
• Healthcare support: the charting system by name (Epic, Cerner), the units you’ve floated to, patient ratios you’ve handled, equipment you’re checked off on.
• Office / admin: the systems that run the place — payroll software, scheduling tools, the reports you build monthly, the vendors you manage, onboarding you’ve handled.

If you can find yourself on O*NET’s occupation profiles, read the tasks and tools listed for your role — it’s a free memory-jogger built from real workplace data, and many people recognize half a dozen things they do but never wrote down.

An example of the difference

Before: “Maintenance technician, kept machines running.”

After a walk through one real shift: “Preventive and breakdown maintenance across 14 production machines · troubleshot Allen-Bradley PLC faults · lockout/tagout authorized · maintained spare-parts inventory and vendor relationships · trained 2 junior techs.”

Same person, same job, nothing invented — the second one just says what the first one assumed everyone knew.

Don’t pad — confirm

The line you never cross: listing something you don’t actually do. Every item you add should be something you could demonstrate on day one. If you’re unsure whether a credential counts, describe the experience instead of claiming the credential.

The Role-by-Role Skills Checklist below prompts you through common skills by job type so you can check off what’s genuinely true for you. Our base build does this with you — proposing skills common to your role and asking you to confirm each one, so nothing lands on the page that you didn’t earn.
