How to Screen Electricians: 9 Questions and What to Listen For Screening Interview Template

What is your current license or classification (apprentice, journeyman, master), who issued it and in which state or city, what is the license number, is it current, how many documented hours do you have toward the next tier, and can you pull a permit under it?

What this assesses: License tier decides what a candidate can legally do on your jobs and how many of them you can put behind one journeyman, so score it first and verify it separately. Know how the tiers work before you read the answers, because hiring managers get this wrong as often as candidates do. Apprentice means registered, supervised, and logging hours toward the next tier, commonly in the range of 8,000 documented hours in many states, though both the hour count and the classroom requirement vary. Journeyman generally means working unsupervised on installation and service. Master is usually the tier that can pull a permit or qualify a contractor license, and an electrical contractor license is a separate business credential on top of that, which is why a shop with no master in it stalls on anything inspected. Two things people assume wrong. First, none of this is national. Electricians are licensed state by state, several states leave it to individual cities and counties instead, and reciprocity where it exists is partial and normally means an application and sometimes an exam rather than an automatic transfer. A journeyman card from the next state over is a starting point, not a qualification. Second, the ratio matters as much as the card. Many jurisdictions cap how many apprentices one licensed journeyman can supervise, often somewhere between one and three, so a fourth apprentice is not a cheaper hire, it is a crew you cannot legally field. Strong answers give the tier, name the issuing authority, produce a license number without being pushed, put a real hour count against the next tier, and answer the permit question with a yes or a no. Be cautious with a candidate who says licensed with no tier or jurisdiction attached, who cannot name the board that issued it, whose number does not match the tier they claimed, or who assumes the card travels. None of this is a judgment call you should make from the answer alone. Most states publish a free license lookup, it takes a minute, and you should run it on every candidate rather than only the ones who sound uncertain.

Is your background mostly residential service, residential new construction, commercial, or industrial? Walk me through a typical day in your last role: how many service calls did you run, or what did you rough in and on what schedule? Were you solo in a van or on a crew, and who handled the customer and the price?

What this assesses: These four backgrounds share a license and almost no muscle memory, and mismatching them is the most common reason a technically strong electrician washes out in the first month. Residential service is diagnosis in a stranger's occupied house, a price quoted at the kitchen table, and five to eight calls on a normal day. Residential new construction is layout, rough-in, and trim at production pace, measured in houses or units per week rather than calls closed, and the inspector matters more than the customer because there is no customer on site. Commercial is pipe, print reading, panelboards, 277 and 480 volt lighting and equipment, and coordination with the mechanical trades and a general contractor's schedule. Industrial is motor controls, motor control centers, VFDs, instrumentation, and shutdown work, often in a plant where the cost of a mistake is measured in lost production per hour rather than in a callback. Strong answers pick a side without being asked to, put real numbers on the day, and name the part they are weaker at. An electrician who says they ran six service calls a day, kept a stocked van, and quoted their own work is describing a very different hire than one who says they never touched a price. Be cautious with a candidate who claims equal strength across all four, which almost always means thin exposure to each, and with anyone who cannot attach a number to their own day. Then calibrate against your work rather than against the resume. A strong commercial hand dropped into a service van will be slow and uncomfortable for a quarter, and a service electrician on a commercial rough will move fast and be out of their depth at the inspection. Either can work if you know which one you hired and you plan the ramp. The failure is finding out in week three.

A homeowner calls: the lights in part of the house have been flickering and sometimes look unusually bright, it gets worse when the air conditioner starts, and a TV and a microwave both died in the last month. Walk me through what you check, in order, and what you tell the homeowner.

What this assesses: This separates an electrician who troubleshoots from one who replaces parts, and the order of the answer is the whole grade. Lights dimming in one part of the house while another part runs bright, plus electronics failing, plus the symptom moving with a large load, all point the same direction: a loose or open neutral on the service or at the main panel, not a problem at any fixture or branch circuit. Strong answers say that in a sentence or two and head for the panel rather than the flickering room. From there the sequence matters. Read both legs to neutral at the main under load, where a healthy service sits near 120 and 120 and an open neutral shows something lopsided like 80 and 160, which is exactly what killed the appliances. Then check the neutral and ground terminations, the main lug torque, and the meter base for heat damage and corrosion, and look at the service drop or lateral. The part most candidates skip is the boundary: if the fault is upstream of the meter it belongs to the utility and nobody should be opening it, and an electrician who makes that call instead of selling a panel change has earned you a customer. The best answers also treat the neutral as dangerous rather than merely broken, because lifting a neutral under load puts voltage where nobody expects it, so they kill the load first. Be cautious with anyone who starts by swapping a dimmer or a breaker, anyone who proposes a panel replacement before they have measured anything, and anyone whose whole answer is which meter they would bring, because the tool is not the diagnosis. On the homeowner half, listen for plain language, a written number before work starts, and an honest split between what has to be fixed today and what can wait.

Which edition of the National Electrical Code does your jurisdiction work under right now, and tell me about a specific time code drove how you did a job. What did the inspector look at that other people get wrong?

What this assesses: This tests whether code is working knowledge or a term on the resume, and the first half is a quiet calibration check. The NEC runs on a three-year cycle, but adoption is state by state and plenty of jurisdictions are one or two cycles behind, so the candidate who names the edition they actually work under beats the one who names the newest edition they have heard of. The second half is where you learn something. Know the common items so you can tell a real story from a manufactured one: box fill, where devices, clamps, and grounds each count toward a volume the box is marked with; conductor sizing and the derating that comes with ambient temperature and too many current-carrying conductors in one raceway; working clearance in front of equipment, which for most panels is three feet of clear depth, thirty inches of width, and no storage shoved into it, and which is the single most-cited item on a commercial inspection; grounding and bonding, where the distinction between a grounded conductor and an equipment grounding conductor, single-point bonding at the service, and the main bonding jumper separate electricians from handymen; the GFCI and AFCI requirements that have expanded with nearly every recent cycle; a legible circuit directory on the panel; and tamper-resistant receptacles in dwellings. A candidate who knows that voltage drop is an informational note rather than an enforceable rule, and designs for it anyway on a long run, is telling you they have read the book instead of memorizing habits. Strong answers name the item correctly, tie it to a decision they made in the field, and describe what changed afterward. Be cautious with answers that wave at following code in generalities, with requirements cited from two cycles ago as current, and with a candidate who treats a code question as a trivia contest rather than describing an actual job.

You open a panel to work on a circuit that is supposed to be dead. Walk me through exactly what you do before you touch a conductor. Separately, when do you work something energized, and what does that change about how you show up?

What this assesses: Score this one pass or fail, because the failure mode is a funeral rather than a callback. On the first half, the correct shape is lockout, then verify, then work. Strong answers identify every source, open the disconnect, apply their own lock with their own key rather than borrowing one, tag it, and then do a live-dead-live check: prove the meter reads voltage on a known live source, prove the circuit is dead, then prove the meter still reads live, because a meter that died in the truck reads zero on everything. They treat supposed to be dead as unproven until confirmed, they test every conductor rather than one, and they use an adequately rated instrument with the right category rating instead of a non-contact pen, which is a good screwdriver light and not a verification tool. OSHA's electrical safety-related work practices at 29 CFR 1910.333 is the rule behind all of this. The second half sorts experience levels fast. De-energizing is the default, and energized work is for the narrow cases where shutting down introduces a bigger hazard or is genuinely infeasible, with testing and troubleshooting being the usual honest example. An electrician who has worked commercial or industrial should be able to talk about arc flash in NFPA 70E terms: equipment labels, boundaries, rated PPE rather than a cotton shirt, and an energized work permit for work inside the restricted approach boundary. Be cautious with a candidate who skips verification, trusts the panel label, jokes about working it hot because it is faster, cannot describe a real lockout process, or has worked 480 volt gear for years and has never heard of 70E. One wrong assumption here is an arc flash, and the cost lands on your insurance, your crew, and someone's family rather than on the schedule.

Tell me about a circuit that kept tripping or a fault that only showed up intermittently. How did you isolate it, what did you find, and how did you confirm the fix before you left?

What this assesses: Troubleshooting separates an electrician who can follow a plan from one who can solve a problem on site without a foreman standing over them, and it is the skill that pays for itself on service work. Strong answers describe a method rather than a result: reproduce the fault, establish whether the breaker is tripping on overload, a short, or arc or ground fault detection, because those are three different problems and the breaker type tells you which, then split the circuit to cut the suspect length in half, clamp the load to see what is actually drawing, and check terminations and junction boxes for heat and loose connections before condemning anything. Good answers name the usual culprits honestly: a shared neutral on a multiwire branch circuit tripping an arc fault breaker, a staple through insulation from someone else's rough-in, a damaged neutral, moisture in an outdoor box or fixture, a motor pulling locked-rotor current on start, or a genuinely failed breaker, which is the rarest of the list and the first thing weak candidates reach for. Experienced hands mention measuring insulation resistance with a megohmmeter when the fault is in a run they cannot see, and measuring voltage drop under load to find a high-resistance connection that looks fine at rest. The confirmation step is where most answers fall apart. Strong candidates load the circuit and watch it, or leave it running and come back, and they write down what they found for whoever gets the next call. Be cautious with anyone who swaps the breaker and hopes, anyone who replaces parts in sequence until the symptom stops, and anyone who cannot explain how they knew it was fixed rather than quiet.

What can you work from and what have you run: blueprints, panel schedules, one-line and riser diagrams, EMT and rigid conduit including offsets and saddles, MC cable and romex, 277 and 480 volt lighting and equipment, transformers, generators and transfer switches, motor controls, VFDs, fire alarm and low voltage, EV chargers, solar. What do you run start to finish on your own, and what do you hand off?

What this assesses: The handoff half is the useful half. Every resume lists every system, and the electrician who can say exactly where their line sits is almost always the one who can work up to it. Strong answers read like an inventory rather than a claim. On prints, listen for pulling circuits and dimensions off a drawing set, laying out homeruns, reading a panel schedule, and working from a riser without being walked through it, because a field electrician who has only taken verbal direction slows the whole crew. On pipe, bending is the clearest experience signal in commercial work: offsets, kicks, and saddles by hand, a hydraulic bender for the larger sizes, and concentric bends on a rack, which is the one that cannot be faked and is the first thing a foreman notices. On voltage, a candidate who has only worked single-phase residential should say so rather than implying three-phase experience, because 277 volt lighting and 480 volt equipment are a different world and the mistakes are not recoverable. Motor controls, VFDs, and PLC-adjacent work are a separate specialty worth paying for if your work needs it and worth ignoring if it does not. Low voltage, fire alarm, and solar are all licensed or endorsed separately in many states, so a candidate who says they pull the wire but do not certify the system is giving you an honest and correct answer. Be cautious with a candidate who claims every system at one level, which is rarely true and shows up later as rework, and be cautious in the other direction if the handoff list runs long enough that you are paying journeyman wages for a helper. Then weight all of it against your actual job mix. If most of your revenue is panel upgrades and service calls, the sentences about diagnostics and homeowners outrank everything else in the answer.

This work means ladders, scissor and boom lifts, attics in summer, crawlspaces, trenches, and lifting material, all of which you would do with or without a reasonable accommodation. What PPE do you actually use day to day, what do you do before you dig or before you cut into a raceway you cannot identify, do you own your hand tools, and do you hold a valid license with a record clean enough to be insured on a company vehicle? Do you have an OSHA 10 or 30 card, and can you clear a site drug screen and background check?

What this assesses: Several filters in one question, and it is better to surface a problem here than after a general contractor's badging process kills the start date. On PPE, the answer should sound like a default rather than an occasion: safety glasses whenever something gets cut or drilled, gloves appropriate to the task, hard hat on any active site, hearing protection around a hammer drill or a saw, and arc rated clothing where the equipment label calls for it. On digging, the only acceptable answer is calling 811 before any dig, every time, with no judgment calls, and treating an unidentified conduit or cable as live until proven otherwise. On lifts, listen for the training the site will ask them to produce rather than a claim that they have driven one before, and for basic fall protection awareness in a boom lift. On tools, the trade norm is that the electrician owns hand tools, a meter, and a set of drivers while the company supplies benders, hole saws, knockout sets, and the heavy equipment, so a candidate who expects you to supply their lineman's pliers has not held this job, and one who claims to own a megohmmeter and a hydraulic bender is worth a follow-up about what they were running and for whom. Ask the physical and environmental part exactly as written, as demands of the job with the accommodation language, and stay out of health history entirely. On driving, ask about insurability rather than history in the abstract, because your carrier decides that one for you. Be cautious with hesitation on a routine drug screen most commercial sites require, with a candidate who overstates what they can physically do to land the job, and with anyone whose only experience is light residential work who has not felt a full August day in an unconditioned attic or eight hours standing in a lift basket.

What is your availability, including early starts, overtime during a push, weekends, and on-call? How far will you travel or work out of town, and under what per diem? What rate or pay structure are you looking for, are you currently in a union agreement, and how soon could you start?

What this assesses: Scheduling and pay are the most common reasons a qualified tradesperson falls through, so put the real terms in this question instead of discovering the mismatch on the offer call. Construction runs early, leans hard on overtime during a push, and moves job sites, and service shops run a rotation. Strong answers give specific availability, name a travel radius, confirm dependable transportation to sites that are rarely on a transit line, and are direct about the constraints they do have, which is more useful to you than enthusiasm. Be cautious with a blanket whatever you need, which collapses the first time a 6 a.m. start an hour away or a week of mandatory ten-hour days lands. Take the pay answer seriously and ask about structure rather than only the number. Service shops often pay a base plus a percentage of the ticket, and an electrician coming off a straight hourly check hears that as a pay cut even when it is not, while someone coming off commission hears flat hourly the same way. Union status is a practical question rather than a political one, because a candidate working under an agreement may have obligations and a wage floor that decide the conversation before you get to fit. A licensed journeyman knows what the market pays and will leave over two dollars an hour, so a candidate who names a number above your band has done you a favor by saying it in week one. On start date, a working electrician who offers to start tomorrow is either between jobs for a reason worth asking about, or is about to leave you the same way. Then score every candidate against the same [interview scorecard](/glossary/interview-scorecard) rather than reading answers one at a time, keep it a [structured interview](/glossary/structured-interview) so a commercial hand and a residential service tech land on the same rubric, and run it as [asynchronous screening](/glossary/asynchronous-screening), because the electrician you want is on a lift at two in the afternoon and is not taking your call. In this trade, [candidate drop-off](/glossary/candidate-drop-off) is the competitor you are actually losing to, and the shop that answers first usually wins.
