Elevator mechanic screening questions: state license, apprenticeship, service routes and modernization
On this page
Elevator mechanic screening questions should confirm the candidate's license status in the job's state (mechanic, limited mechanic or apprentice), the apprenticeship they came through, whether their recent work is new construction, modernization, repair or a service route, and which equipment they know: hydraulic, geared or gearless traction, machine-room-less units or escalators. Then ask about the last callback they ran alone and how they lock out a car before entering the hoistway. Licensing is set state by state, so check the state's own agency as of October 2026 before you screen anyone out.
This page is specific to elevator and escalator work. For general electrical licensing and safety questions, use electrician screening questions; for the rigging and precision installation side that elevator constructors share with millwrights, see millwright screening questions. Building maintenance staff who only reset elevators belong under maintenance technician screening questions.
Construction, modernization, repair or service: which job is this?
| Type | What the work usually involves | A question that tests it |
|---|---|---|
| New construction | Installing rails, machines, controllers, doors and cars in new buildings, usually as a crew of a mechanic and an apprentice | "On your last install, what did you set yourself, and who checked the rail alignment?" |
| Modernization | Replacing controllers, machines, door equipment or fixtures in existing buildings while tenants still use other cars | "Tell me about a controller replacement you led. What did you keep and what did you replace?" |
| Repair | Larger planned repairs: ropes, sheaves, hydraulic jacks, door operators | "What was the biggest repair you led, and how long was the car out of service?" |
| Service route | A set of buildings, routine maintenance, callbacks and entrapments, often with on-call | "How many units on your route, what types, and how many callbacks a week?" |
| Residential and accessibility lifts | Home elevators, wheelchair lifts, stair lifts; often a separate or limited license | "Which lift types and which license did you work under?" |
Which licenses and credentials should an elevator mechanic have?
The Bureau of Labor Statistics' Occupational Outlook Handbook says the career typically begins with a 4-year apprenticeship sponsored by a union, an industry association or an employer, and that most states require elevator and escalator installers and repairers to be licensed. Checked on the agencies' and issuers' own pages as of October 2026:
| Credential | What it is | What to ask |
|---|---|---|
| State elevator mechanic license | Issued by the state's elevator safety agency, sometimes with separate city rules. Illinois, for example, has the Office of the State Fire Marshal's Elevator Safety Division license contractors, mechanics, inspectors, inspection companies and apprentices for conveyances outside the City of Chicago, with mechanic and limited mechanic tests. | Which state, which license class (full or limited), the number and the expiry date. |
| Union apprenticeship (NEIEP) | The National Elevator Industry Educational Program runs the apprenticeship for the International Union of Elevator Constructors (IUEC). | When they finished, and whether they passed the mechanic exam. |
| NAEC CET and CAT | The National Association of Elevator Contractors runs Department of Labor approved apprenticeship programs: CET (Certified Elevator Technician) and CAT (Certified Accessibility and Private Residence Lift Technician). | Which program and level, and the year they completed it. |
| QEI | An inspector certification. NAESA International says its QEI exam is for people who meet the experience requirements of the ASME QEI-1 standard. It shows code knowledge; it is not a mechanic license. | Only relevant if the role includes inspection or code compliance work. |
Two practical points. Licenses are issued state by state, and some cities add their own, so ask where the license was issued, not only whether they have one, and check the job state's rules for out-of-state holders. And union and non-union employers fill jobs through different channels, so confirm with the client how this role is filled, and under which agreement, before you call.
Knockout questions
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| This job is in [state or city], which requires [license]. Which elevator license do you hold, and where was it issued? | A class, a number and an expiry date, or "I hold an apprentice license and test next spring". | "I'm licensed" with no state, or a license from another state described as transferring. |
| Are you a mechanic or an apprentice, and how many years of apprenticeship did you complete? | A clear status and the program. | "Basically a mechanic" without having tested. |
| This role is [construction / modernization / service route]. How much of your last two years was that work? | A split by type: "About 70 percent service route, the rest repair." | All recent work in a different type. |
| The role includes on-call [example: one week in four] for entrapments and shutdowns. Can you take that rotation? | Yes, and asks about response time and pay. | Yes, then a list of weeks they cannot cover. |
| You would drive a company vehicle to [example: buildings across the metro area]. Is your driver's license current? | Yes, with any restriction that matters mentioned now. | Unsure; the client's driving record check will settle it. |
Equipment and troubleshooting questions
-
"Which equipment have you worked on most: hydraulic, geared traction, gearless traction, machine-room-less, escalators?"
- Strong answer: a split, the controller brands, and which ones they can troubleshoot alone versus only maintain.
- Red flags: "All of it." Proprietary controllers often need the manufacturer's service tools, so a candidate should say which ones they had access to.
-
"Tell me about the last callback you ran alone, from the call to returning the car to service."
- Strong answer: the symptom, the fault codes or logs, the circuit or component they traced, the fix, the test runs, and what they told the building.
- Red flags: reset the controller and left. Repeated callbacks on the same unit that they never traced.
-
"A hydraulic car is settling at the floors overnight. Where do you start?"
- Strong answer: checks valve adjustment and leakage, oil level and temperature, the jack and piping for leaks, and the leveling behavior, in a logical order.
- Red flag: adds oil and leaves.
-
"How do you run a door operator problem that only happens at busy times?"
- Strong answer: watches it in service, checks door equipment and safety edges, reads the controller's fault history, and talks to building staff about when it happens.
- Red flag: jumps a door circuit to get the car running.
Safety and entrapment questions
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| How do you secure a car before you go on top of it or into the pit? | Follows the employer's procedure: removes the car from service, uses the inspection controls, locks out the mainline disconnect under OSHA's lockout/tagout standard where power is off, tests stop switches before relying on them, and blocks a hydraulic car where required. | "I just hit the stop switch." Any story about riding the car top without a procedure. |
| Walk me through an entrapment call. | Talks to the passengers, confirms the car's location and state, follows the company's rescue procedure, never pulls people out between floors without securing the car. | Forces doors without knowing where the car is. |
| When have you used a jumper, and how did you control it? | Only under the company's jumper control procedure, logged and removed before returning to service. | Leaves jumpers in "temporarily". |
| How do you work near an open hoistway on a construction site? | Barricades, fall protection, tie-off points, coordination with other trades. | Treats barricades as optional. |
How does elevator experience get overstated?
- Apprentice years as mechanic years. Ask when they tested out and how long they have worked on their own license.
- Building maintenance as elevator work. Resetting cars and calling the contractor is not elevator mechanic experience.
- Install crew as troubleshooter. Years on construction crews with little service or callback work, for a route job.
- Brand access claimed. "Worked on" a proprietary controller without the service tool. Ask what they could actually do on it.
- Route size inflated. Ask how many units and how many were theirs alone.
Scoring
Knockouts are pass or fail. Score the rest 0 to 2 so every mechanic on the order is compared the same way.
Pass or fail
- Holds the license the job's state and city require, or the role is an apprentice role.
- Recent work in the same type (construction, modernization, repair or service).
- Accepts the on-call rotation and driving.
Scored, 0 to 2 each (10 possible)
- Equipment match: the client's equipment types and controllers.
- Troubleshooting method: the callback story.
- Safety habits: car securing, lockout, jumpers.
- Entrapment and customer handling.
- Documentation: maintenance records and callback notes.
General information, not legal advice. Licensing rules differ by state and city and change over time; confirm with the agency where the work is done. Describe the physical work (climbing, pits, machine rooms, heavy components) and ask whether the candidate can perform it, with or without accommodation, rather than asking about health. Ask about pay expectations, not pay history; see salary expectation questions.
The interview guide for skilled trades shows how to add a practical test after the screen. License classes, controller brands and route sizes are the details that blur across a week of calls. Interview Signal keeps the knockout questions pinned until you ask them and writes the notes from what each mechanic said, with the transcript kept on your own computer.
Questions people ask
Do elevator mechanics need a license?
In most states, yes. The Bureau of Labor Statistics says most states require elevator and escalator installers and repairers to be licensed, and the rules are set state by state, sometimes with separate city rules. Illinois, for example, licenses elevator mechanics through the Office of the State Fire Marshal for work outside the City of Chicago. Check the job state's elevator safety agency for the license the work requires.
How do elevator mechanics usually train?
The BLS says the career typically begins with a 4-year apprenticeship sponsored by a union, an industry association or an employer. Union apprentices train through the National Elevator Industry Educational Program (NEIEP), and the National Association of Elevator Contractors runs Department of Labor approved CET and CAT apprenticeship programs. Ask which program the candidate completed and when they became a mechanic.
Is QEI certification the same as an elevator mechanic license?
No. QEI (Qualified Elevator Inspector) is an inspector certification; NAESA International says its QEI exam is for people who meet the experience requirements in the ASME QEI-1 standard for elevator inspectors. It shows code knowledge, but it does not replace the state mechanic license the job requires.
