Electrician screening questions have to establish three things before anything else: what license the candidate actually holds and in which state, which setting their hours come from (residential, commercial or industrial), and whether they can work safely on the client's kind of system. A journeyman with ten years of house wiring is not a fit for a 480-volt plant maintenance role, and the job title on the resume will not tell you that. The questions below will.
They are grouped in call order, each with what a strong answer sounds like and the red flags trades recruiters learn to hear. You do not need to be an electrician to use them. For the general structure of a screen, see phone screen questions for recruiters.
License levels mean different things in different states
"Apprentice, journeyman, master" is the common ladder, but the hours, exams and even the names are set by each state, and in some states by cities and counties. Three examples, checked on the regulators' own pages as of September 2026:
| Jurisdiction | How it works | What to ask |
|---|---|---|
| Texas | TDLR licenses apprentices, journeymen, masters and several specialty types. A journeyman electrician needs 8,000 hours of on-the-job training under a Texas-licensed master (7,000 to sit the exam early). A master electrician needs two years as a journeyman and 12,000 hours. | Which Texas license, the license number, and the expiry date. Residential wireman is a separate, narrower license. |
| California | People doing electrical work for a C-10 licensed contractor must be certified by the state. General electrician requires 8,000 hours; residential electrician requires 4,800. Those without the hours register as electrician trainees, which requires enrollment in a state-approved school. | General or residential certification, or trainee registration and school. The state has a certification search. |
| Pennsylvania | The Department of Labor and Industry says the state has no licensure requirements for most construction contractors or their employees; some municipalities set their own, commonly for electricians. | Which city or township licenses they hold, and whether the job site's municipality requires one. |
The practical rule: get the license type, the issuing state or city, the number and the expiry date on the call, then look it up on the board's public search before you submit. A license that exists in another state is a conversation about reciprocity or testing, not a match.
Knockout questions
Ask these first. Confirm with the client which ones are truly fixed; a helper or apprentice order has different knockouts from a foreman order.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| What electrical license or certification do you hold right now, issued by which state or city, and when does it expire? | "Texas journeyman, renewed in March." Gives the number without hunting for it, or offers to text a photo. | "I have my journeyman hours" (hours are not a license). A license from a state where the job is not. |
| If you are an apprentice or trainee: are you registered, with which program or school, and how many documented hours do you have? | A registration, a program or school name, and an hour count from their records. | No registration in a state that requires it. An hour count that is a guess. |
| This job is [new commercial construction / plant maintenance / residential service]. How many of your hours are in that kind of work, and when was the last time? | Splits their years by setting: "Four years commercial, the last two on tenant build-outs." | "I've done it all." The only matching experience is from early in their apprenticeship. |
| The shift is [hours], starting [date], at [site]. Can you work that every scheduled day? | A plain yes, with how they will get there. | Needs to finish a current job that runs past the start date, mentioned only when you push. |
| The role requires a valid driver's license to drive the company van. Is yours current? | Yes, and they volunteer any restriction that matters. | Unsure. If driving is required, the client's MVR check will settle it. |
| The client requires [OSHA 10 / OSHA 30 / a site safety orientation / a drug test and background check]. Can you meet that before the start date? | "I have my OSHA 30 card from 2024" or "Yes, I can do that this week." | Claims a card they cannot produce. Hesitation about a stated drug test policy is worth noting, not probing. |
Residential, commercial or industrial: questions that separate them
This is where electrician placements fail most often. The settings use different materials, voltages and working methods, and a strong electrician in one can need months to be productive in another.
| Setting | What the work usually involves | A question that tests it |
|---|---|---|
| Residential | Rough-in and trim-out in houses and apartments, NM cable, panel changes, service upgrades, troubleshooting in occupied homes | "Walk me through the last service upgrade you did, from the first call to the inspection." |
| Commercial | Offices, retail, schools; conduit (often EMT) and MC cable, three-phase panels, working from drawings, tenant improvements, coordination with other trades | "On your last commercial job, what did you install, from which set of drawings, and who did you report to?" |
| Industrial | Plants and processing sites; rigid conduit, 480-volt equipment, motor controls, VFDs, PLC-connected systems, maintenance and breakdown troubleshooting | "Tell me about a motor or line that went down on your shift. How did you find the fault?" |
| Specialty and low voltage | Fire alarm, data, security, solar, signs; often separate certifications or licenses | "Which systems, which manufacturers' panels, and which certification covers that work in your state?" |
Experience questions with strong answers and red flags
-
"Walk me through the last service upgrade or panel change you did."
- Strong answer: steps in order: the load or size decision, the permit, coordinating the disconnect with the utility, the swap, the inspection. Names the amperage.
- Red flags: only the result ("we upgraded it to 200 amps"). Ask "what did you do first?" and listen for whether the sequence appears.
-
"When did you last bend conduit, and what size and type?"
- Strong answer: a recent job, the type and size, and whether they used a hand bender or a machine.
- Red flags: for a commercial or industrial role, "the helpers did that" or not since their apprenticeship.
-
"How do you work from a set of prints? Tell me about a time the drawings did not match the site."
- Strong answer: they read the plans themselves, flagged the conflict to the foreman or general contractor, and waited for an answer before changing the install.
- Red flags: "I just figure it out in the field" with no mention of telling anyone.
-
"Tell me about the hardest fault you have troubleshot in the last year."
- Strong answer: the symptom, the meter readings or tests, what they ruled out, the cause and the fix. Industrial candidates mention controls, drives or schematics.
- Red flags: they replaced parts until it worked, and cannot say what was wrong.
-
"Have you run a crew? How many people, on what kind of job?"
- Strong answer: a number, the project type, and what they owned: layout, material orders, daily assignments, inspections.
- Red flags: "lead" on the resume turns out to mean the most senior person on a two-person truck. Fine, but not a foreman.
Code and safety questions
You are not testing code articles on a phone screen. You are checking that the candidate works to a code, follows lockout, and treats energized work as an exception. Those three habits separate electricians clients keep from electricians who get walked off a site.
The NEC
The National Electrical Code is NFPA 70. NFPA says it is updated every three years, and the 2026 edition is the current one. States and local jurisdictions adopt editions on their own schedules, often with amendments, so the edition an inspector enforces can differ from the newest. NFPA keeps a map of where each edition is enforced.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Which NEC edition were your last jobs inspected under? | Names the edition, or says "whatever the county adopted, 2023 I think," and knows it varies by jurisdiction. | Has never heard that editions differ. |
| Tell me about a job that failed inspection. What was the correction? | A specific write-up and the fix, without blaming the inspector. | "Never failed one" from someone with years of permitted work. |
| How do you keep up with code changes? | Continuing education for license renewal, a code update class, the foreman's briefings. | Nothing, in a state that requires continuing education to renew. |
Lockout, energized work and OSHA cards
OSHA's construction standard on lockout and tagging of circuits requires that deenergized equipment and circuits be made inoperative and tagged where they could be energized. Ask about it directly.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Walk me through what you do before you work on a circuit. | Identify the source, shut it off, apply their own lock and tag, then test that it is dead before touching it. | Skips the test step. "I can tell it's off." |
| Have you ever been asked to work on something live? What did you do? | Describes the employer's energized work procedure, the PPE, or saying no until one existed. | Treats working hot as normal and a point of pride. |
| Do you have an OSHA 10 or 30 card? When and where did you complete it? | A card type, a year, and the trainer or employer who ran it. | A card bought online with no memory of the content, or a date that keeps moving. |
Know what the card is. OSHA describes its Outreach Training Program as voluntary: the 10-hour course gives entry-level workers awareness of common hazards, the 30-hour course is aimed at supervisors and workers with safety responsibility, and the courses do not meet the training requirements of any OSHA standard. Its facts about OSHA cards say a card is not a certification or license, although some states, municipalities, employers and unions require the training. So "OSHA 30" on a resume answers the client's site requirement, not the lockout question.
Tools, travel, schedule and pay
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| The client expects you to bring your own hand tools and supplies power tools. Is your set complete? | "Yes, full set, and my own meter." Asks what the client provides. | A journeyman with no tools, for a role that expects them. |
| This is [a local job / an out-of-town project for about X weeks, with per diem]. Does that work? | A clear yes, or a clear limit: "I'll travel but I need to be home every other weekend." | Agrees to travel, then asks about daily home time. |
| The schedule is [10-hour days, some Saturdays / rotating maintenance shifts / on-call one week in four]. Any problem with that? | Yes, or a specific limit you can take back to the client. | "I'll make it work" with visible hesitation. Ask what would make it hard, and stop if the answer is personal. |
| The rate is [$X per hour, overtime after 40, per diem of $Y]. What do you need to make this move? | An hourly number and what else they weigh: overtime, per diem, the length of the job, benefits. | Only the headline rate, with no view on hours per week or job length. |
| Why are you leaving your current job, or why did the last one end? | Fits the trade: the project ended, the contractor lost work, they want industrial experience. | Walked off several jobs mid-project, with a different reason each time. |
Ask what they need to earn, not what they earn now. Pay history questions are restricted in a number of states and cities; the wording is in salary expectation questions.
How electrician experience gets overstated
- Hours counted as a license. "I have my journeyman hours" means eligible to test, at best. Ask whether they have passed the exam.
- Helper time as electrician time. Years pulling wire and carrying material described as installing and terminating.
- One setting stretched to cover three. A residential electrician who did one commercial job describes "commercial experience".
- A license in the wrong place. Valid in the state they left, not where the job is.
- "Foreman" without a crew. Ask how many people, and who did the material orders.
- Industrial by building, not by work. Wiring lights in a factory is commercial-style work in an industrial building. Ask about motors, controls and drives.
Knockout checklist and lawful wording
Before you submit an electrician
- License or certification type, issuing state or city, number and expiry recorded and checked on the board's public search.
- The license is valid where the work is, or the client has agreed to a trainee or apprentice under supervision.
- Hours in the client's setting (residential, commercial, industrial) meet the order, with the last date.
- Lockout answer includes testing before touching.
- OSHA card or site safety requirement met, if the client requires one.
- Own hand tools, if expected; driver's license, if driving is required.
- Yes to the actual schedule, travel and job length, and to the rate.
- Consent to submit for this client and this job, with the date.
General information, not legal advice. Rules differ by state and city. Confirm with your agency's or client's counsel for the places you recruit.
Describe the physical work and ask whether they can do it. The EEOC's guidance on pre-employment disability-related questions allows asking whether a candidate can perform the job's functions, with or without accommodation, but not about conditions, injuries, medications or workers' compensation history before an offer. For example: "The job involves working from ladders and lifts up to 30 feet, in crawl spaces and attics, and identifying color-coded conductors. Can you perform those duties, with or without accommodation?"
Leave out age, where they are from, family and childcare, and union membership. The National Labor Relations Board says employers may not refuse to hire applicants because of union membership, activities or sympathies. Ask about the projects instead. Leave criminal history to the client's background check process, which in many places is restricted before an offer; see ban-the-box rules for interview questions.
Trades screens often happen from a truck at lunch, and license numbers, hour counts and expiry dates are exactly the details that get mixed up across a day of calls. Interview Signal takes phone screens through your computer's audio with no bot on the call, so what the electrician said about their license and hours is in the notes as they said it.
Questions people ask
Is a journeyman license from one state valid in another?
Not automatically. Licensing is set by each state, and in some states by cities or counties. Some jurisdictions have reciprocity agreements for certain license types, so check the licensing board where the work will be done before you tell a traveling electrician they can work there.
Does an OSHA 30 card mean an electrician is safety certified?
No. OSHA says its Outreach Training Program is voluntary, that the cards are not a certification or license, and that the courses do not meet the training requirements of any OSHA standard. Treat the card as evidence of awareness training, and ask about lockout and energized work separately.
How can a recruiter who is not an electrician tell if experience is real?
Ask for the last specific job in the setting the client needs and listen for sequence and detail: who pulled the permit, what size the service was, what they installed first, what failed inspection. People who did the work describe steps in order without being led. People who watched it describe outcomes.
Can I ask an electrician if they are in the union?
Avoid it. The National Labor Relations Act makes it unlawful to discriminate in hiring based on union membership or sympathies, and questioning about union activity can be treated as interference. Ask about the projects they worked on and the wage and benefit terms the job offers instead.
