Working interviews for mechanics: how to run one legally and what to evaluate

A working interview is a scheduled block of shop time in which a finalist performs representative tasks while you observe.

It shows what a resume, a phone screen and a sit-down conversation cannot: how the candidate handles your tools and your workflow, follows a written procedure, sets a pace, and asks questions when the job calls for them.

It is an evaluation, not coverage for a short-staffed afternoon.

The candidate is there so you can watch real work, and every part of the day — the task list, the supervision, the pay status — should be built around that purpose.

Place it late in your sequence, after the in-person interviews and before the offer decision, so the try-out is the last evidence you weigh before you commit.

You can also run bounded hands-on skills tests — a measured task or a written diagnostic exercise — instead of or alongside a try-out.

Required skills tests fall squarely under the EEOC’s test rule below; hold a try-out to the same job-related standard.

A working interview is one step in hiring for your shop, not a substitute for the screening around it.

References, the credentials you verify and the rest of your process still stand; the try-out adds observed work to that file.

Yes: treat the day as paid time.

A candidate performing real repair work — the kind a shop bills for — is hard to fit outside employee status, and employee status is what carries the minimum wage and overtime requirements of the Fair Labor Standards Act.

The closest federal guidance is the DOL’s Fact Sheet 71 on internships.

It describes the primary beneficiary test courts use to decide whether an intern or student at a for-profit employer is an employee owed minimum wage and overtime.

The factors include whether the person’s work complements paid employees’ work or displaces it, and no single factor decides the question.

Two things follow for a try-out.

First, a candidate doing real repair work on vehicles the shop bills is producing exactly the kind of work that test examines.

Second, our research found no DOL fact sheet or federal rule that specifically approves an unpaid working interview, so our research turned up no published federal guidance to lean on if you run one without pay.

The wage-hour rule closest to a try-out points the same direction, and it is written about employees.

Under 29 CFR 785.27, time an employee spends in training, lectures or meetings counts as paid working time unless all four conditions are met.

Those conditions: the time falls outside regular working hours, attendance is truly voluntary, it is not directly related to the employee’s job, and no productive work is performed.

A working interview is built to be directly related to the job and to include productive work, so it does not fit those conditions — and our research found no rule or guidance treating an unpaid try-out differently.

So pay the candidate through payroll for the hours worked, at the rate you would pay for that work, and record the time like any other shift.

Paying also keeps the comparison clean: every candidate for the role is on the same paid footing.

The FLSA itself does not override your state’s wage law: the statute provides that no provision of the FLSA excuses noncompliance with any state law setting a higher minimum wage or a shorter maximum workweek.

Confirm how your state treats candidate time with your state labor agency or employment counsel — before you run an unpaid try-out.

A working-interview candidate is neither a current employee nor a customer, and that in-between status is where the insurance questions live.

Settle them with your insurance agent or broker before you schedule the day, not after something happens.

State rules on whether workers’ compensation responds to a candidate hurt during a try-out did not surface in our research, so this page will not guess at them.

Ask your broker, and get the answers in writing.

Does workers’ compensation cover a non-employee working in the shop in your state?

Do your garage liability and garagekeepers policies respond to damage a candidate causes to a customer vehicle or to shop equipment?

How does the insurer want a candidate documented for the day?

The rest is process you control.

Decide the task list before the candidate arrives, decide which vehicles they may touch, and keep supervision with you or a lead for the whole block.

Whatever your insurer says about paperwork, your own record of the day — who supervised, what was assigned, what was completed — should read like a work record, because with a paid try-out that is what it is.

The answers live in your policy documents, not on this page — treat none of this as an insurance ruling for your shop.

Get the broker’s answers before the candidate’s first shift and keep them with your hiring file.

Start from the EEOC’s rule on required tests: a test must be necessary and related to the job, and it must not exclude applicants on a protected trait.

A test that screens out applicants 40 or older must be based on a reasonable factor other than age.

Applied to a try-out, that means the task list comes from your job description, and every candidate for the same role works the same list.

Assign by the level you are hiring, using your shop’s own definitions of that level — your ladder, not an industry one.

What changes between levels is the difficulty and independence of the tasks, not the structure of the day: representative work, shop tools, supervised, scored.

Build the day around unbillable work — shop vehicles, training aids, wheels and cores you supply — so the candidate’s output stays on the evaluation side of the line and off billed customer-pay work.

That keeps the DOL factor above in view: the test asks whether the person’s work complements what your paid crew does or displaces it, and no single factor decides the question.

• General service or entry hire: a maintenance sequence on a shop vehicle — oil and filter, a multi-point inspection, findings written down the way they would land on a repair order.
• Tire or lube hire: a mount, balance and inspection sequence on units you supply, run at your normal pace.
• Line tech: a no-start or stored-code concern on a shop vehicle, diagnosed and written up as if the service advisor were waiting on the answer.
• Diagnostic or electrical hire: a reproducible fault on a training vehicle, worked through out loud — symptom, tests in order, a conclusion that follows from the results.
• Collision hires: the same structure holds — a prep-and-tape sequence for a prep tech, an estimate on a stored shell for an estimator candidate.

Make the tasks match the work as it physically exists.

The Bureau of Labor Statistics’ Occupational Outlook Handbook describes automotive service technicians’ work as sometimes requiring them to lift and maneuver heavy objects such as tires, and as usually standing for most of the day.

It also lists working with greasy parts sometimes in uncomfortable positions, and possible exposure to fumes, chemicals and noise.

A try-out built from lighter desk-style tasks is not showing you the job.

What the day should not include is medical screening.

The EEOC’s guidance is that employers generally cannot ask disability-related questions or require medical exams until after a conditional job offer.

After a conditional offer, an exam is allowed only when all new employees in the same job must take it, and the answers must be kept confidential.

Before an offer, you may ask whether the applicant can perform the job and how they would perform it.

If a task raises the question, score the performance you observed; do not turn the try-out into a physical.

Leave credentialed work with your credentialed staff unless the candidate already holds the card.

Refrigerant service is the clean example: under section 609 of the Clean Air Act, any person who repairs or services a motor vehicle A/C system for consideration — payment or bartering — must be trained and certified by an EPA-approved program.

On a paid try-out, a candidate without the card observes that bay rather than works it.

Plan the day around your tools, and say in the confirmation what the candidate should bring.

BLS notes that technicians use computerized diagnostic tools and power tools — pneumatic wrenches, lathes, welding torches, jacks and hoists — and that these tools “usually are owned by their employers.”

That usually puts the equipment on the shop’s side, so the try-out runs on your tools; whether to bring hand tools is your call, and the invite should say so.

Write the scorecard before the candidate arrives, and score every candidate for the role on the same criteria.

A sheet built after the day invites gut feel; a sheet built before it keeps the comparison honest.

Consistency is your own discipline to enforce — decide the criteria before you meet the first candidate, and draw them from the job description so they satisfy the EEOC’s requirement that a required test be necessary and related to the job.

• Procedure discipline — did they verify the complaint before replacing parts, pull the service information, and check their own work?
• Diagnostic sequence — symptom, tests in a logical order, a conclusion that follows from the results.
• Documentation — findings written the way they would land on your repair order.
• Communication — questions asked at the right moments, findings explained plainly, roadblocks flagged instead of hidden.
• Bench habits — bay left organized, tools accounted for, honest about what they did not finish.
• Work within your safety process — PPE worn, and lift and equipment use as your own training lays out.

Score each criterion on a simple scale you define, and write examples rather than adjectives: “asked for the wiring diagram before touching the intake” beats “good diagnostician.”

Take the notes during the day rather than from memory that evening, and have whoever supervised fill out their own sheet before anyone compares.

Score the work, not the person.

Notes on age, family, accent, appearance or anything else unrelated to the tasks have no place on the sheet, and criteria that are not related to the job run against the EEOC’s requirement that a required test be necessary and related to the job.

If a criterion would not appear in your job description, it does not belong in the scoring.

Weigh the sheet alongside everything else in the file: interview answers, references, the credentials you verified, and how the candidate took direction from your crew.

The try-out is one input — a heavily weighted one on the work columns — but a hire is a whole-file decision.

Confirm before you schedule.

Pay status, insurance coverage and the test rules are the three checks to settle before a candidate books a try-out.

Take pay to your state labor agency or employment counsel, coverage to your insurance agent or broker, and an unusual screening process to the EEOC’s guidance.

Employer information for shop owners and managers, not legal, tax, insurance or safety advice; confirm the rules above with the DOL, the EEOC, your state labor agency, your broker or counsel as each question requires.
