Acing an interview in the service trades: 12 common questions

By Sandrine Côté · Published November 2, 2026 · 9 min read

Informal job interview in a garage office between a mechanic and a young candidate over coffee

Tuesday, 7:50 a.m. You're in the parking lot of a landscaping company, ten minutes early, palms a little sweaty. The boss is going to ask questions standing next to a truck, not behind a desk. Good news: in the service trades, the questions almost always come back. Here are the 12 most common ones, what the employer is really looking for behind each, and the ones you should ask in return.

What the employer is really looking for

In an office, the interview often revolves around the résumé. In the service trades, it checks three things: will you show up, do you work safely, and do you know how to behave at a client's place. The rest gets learned on the job. No résumé? Don't panic: Finding a job without a résumé in Quebec: the complete guide explains how to do without one.

The interview is often short: a ten-minute call, a meeting at the garage, sometimes a site visit. Show up with what you need:

your driver's licence, and the class of vehicle it lets you drive;
your cards and certificates (first aid, ASP Construction if the job involves a construction site, etc.);
your availability in writing: days, evenings, weekends, on call;
how you get to work;
your boots, if a site visit is possible;
one or two references: a former boss, a satisfied client.

Do it today: write your typical weekly availability in your phone. It comes up in almost every interview, and it's the one people stumble on most.

By phone, at the garage or on a trial day: three formats

In the service trades, an interview rarely means a desk and a chair. Depending on the employer, it happens in one step or in three. Each format has its traps.

Format	What the employer watches for	What you do
Ten-minute call	Your availability, how you talk, your tone when you're interrupted	Answer somewhere quiet, or call back within the hour if you're on a job site
Meeting at the garage or on a job site	Your punctuality, your appearance, your boots, how you look at the equipment	Show up ten minutes early and ask a question about the equipment
Trial day	Your pace, your caution, how you follow instructions	Ask ahead of time for the hours, the location, what equipment to bring and the rate

The trial day deserves a closer look. Under section 57 of Québec's Act respecting labour standards, an employee is deemed to be at work during any trial or training period required by the employer. A trial day the employer asks for is therefore work time. Write down your arrival and departure times in your phone, like any other workday. On the employer side, how to run a good trial is explained in Assessing a candidate without a résumé: trial days and the questions that matter.

Your voicemail counts too. An employer who calls at 7 a.m. and hits a full mailbox, or a joke greeting recorded in high school, often moves on to the next candidate. A simple message is enough: your first name and "leave me a message, I'll call you back today."

Do it today: call yourself and listen to your own greeting. If it makes you cringe, re-record it before you apply.

Reliability: questions 1 to 4

1. "Tell me about yourself."

The employer doesn't want your life story. Three sentences are enough: what you've done, what you can do, why this job. For example: "I've done three landscaping seasons, I drive with a trailer and I know the riding mower. I'm looking for year-round work, and snow removal in winter interests me."

2. "How do you get to work?"

Behind the question: will you be there at 6 a.m., even in February? Answer concretely: your car, carpooling, the bus and what time you can arrive. No car? Say so, along with your plan.

3. "What do you do if you're going to be late?"

The right answer fits in one sentence: "I call before the start time, not after, and I give a realistic arrival time." A boss forgives a late arrival that was announced, rarely a silent one.

4. "Why did you leave your last job?"

Short, honest, without badmouthing anyone. "The season was over and I'm looking for something year-round" beats ten minutes about your old foreman.

Do it today: practise these four answers out loud, once, in your car. It feels silly; it works. People walking by will just think you're on the phone.

Licences, cards and availability: questions 5 to 8

5. "What licence do you have?"

Know your class. According to the Société de l'assurance automobile du Québec (SAAQ), a Class 5 licence lets you drive a 2-axle vehicle with a net mass under 4,500 kg, as well as tool vehicles such as a loader or grader. A 2-axle truck of 4,500 kg or more, or a truck with 3 or more axles, requires Class 3. If there's an issue with your licence, don't hide it: it always comes out.

6. "What's your availability?"

Be specific: "Monday to Friday, 6 a.m. to 5 p.m., and Saturdays on call." Avoid "I'm flexible" if it isn't true: the employer will believe you and call you on a Sunday.

7. "Do you have your cards?"

Give the exact name of each card and its date. If one is missing, say whether you're ready to take the training.

8. "Are you comfortable working nights, on call or in the cold?"

In snow removal, building maintenance or delivery, this is central. Answer honestly. A clear no today beats quitting in January.

On GPP Emploi, these answers are already in your profile: availability, cards, Passport with verified badges. The employer who invites you has seen them; the interview is there to confirm. To know what to do when the invitation arrives, read Answering an employer's invitation: accept, decline or ask your questions.

Do it today: make sure your profile says exactly what you'll say in the interview. A gap between the two raises doubts.

Safety, clients and pay: questions 9 to 12

9. "Tell me about a time you stopped a task because it was dangerous."

The employer wants someone who stops, not a hero. One example is enough: "The ladder was on ice, so I waited until it was secured before climbing."

10. "A client isn't happy with your work. What do you do?"

Listen, don't argue, write down the problem and let the boss know. In painting or house cleaning, how you take a complaint matters as much as the work itself.

11. "Do you prefer working alone or in a team?"

State your preference, then show you adapt: "I like doing my route alone, but I give the crew a hand when it's busy."

12. "How much do you want to make?"

Know the floor: the minimum wage has been $16.60 an hour in Québec since May 1, 2026. Above that, give a range based on your experience and what job ads in your trade show for your region.

Do it today: open the job ads in your trade and region and write down the lowest and highest rates. That's your range.

The questions they're not allowed to ask you

Québec's Charter of human rights and freedoms (s. 18.1) prohibits asking, in a job application form or during an interview, for information about the grounds listed in section 10, except as provided in the Charter. These grounds include race, colour, sex, gender identity or expression, pregnancy, sexual orientation, civil status, age (except as provided by law), religion, political convictions, ethnic or national origin, social condition and disability.

Examples of questions an employer should avoid:

"Are you pregnant, or planning to have kids soon?"
"How old are you?"
"Are you married?"
"What's your religion?"

The Québec government's Boîte à outils RH (HR toolkit) gives examples of compliant questions: they target the job, not the person.

Topic	Avoid	Fine, because it's tied to the job
Age	"How old are you?"	Checking that you meet the minimum age, if the job has one
Children, pregnancy	"Are you planning to have kids?"	"Will you be available for the planned period of employment?"
Religion	"Are you available on religious holidays?"	"Are you available evenings and weekends?"
Origin	"Where are you from originally?"	"Are you legally entitled to work in Canada?"
Health	"Do you have any health problems?"	A question about a specific requirement of the task

On health, the Commission des droits de la personne et des droits de la jeunesse explains, in its tool on section 18.1, that questions about health fall under the ground of "handicap" (disability): the employer must be able to show a rational connection with the job, and the Commission recommends keeping medical questionnaires for selected candidates, after a conditional job offer. In moving, "The job means carrying heavy boxes all day; does that work for you?" is about the task. "Have you ever had back pain?" is about you.

For criminal records, section 18.2 provides that you can't be refused a job solely because you were convicted of an offence, if it has no connection with the job or if you've obtained a pardon. If a question makes you uncomfortable, answer calmly: "Is that related to the job?", or steer the conversation back: "What I can tell you is that I'm available Monday to Friday." For a specific situation, the Commission des droits de la personne et des droits de la jeunesse (Québec's human rights commission) can inform you.

Do it today: prepare your redirect sentence and say it once out loud. The day you need it, it'll come out on its own.

The questions to ask in return

An interview goes both ways. A candidate who asks good questions looks serious, and avoids bad surprises in the first month.

What's the hourly rate, and when is payday?
How many hours a week, on average, and how is the schedule given?
Is travel time between clients paid? (What the law says is in Travel time between clients: is it paid?.)
Who supplies the equipment and protective gear: boots, gloves, harness?
Is there a trial or training period? Under the Act respecting labour standards, an employee is deemed to be at work during any trial or training period required by the employer.
What happens on bad-weather days?

AI can help you prepare your answers and questions: Using AI for your job search: profile, messages and interviews. For preparation, of course; during the interview, you're the one talking.

Do it today: pick three questions from the list, write them in your phone, then complete your profile so the invitations start coming in.

The bottom line

A good interview in the service trades is mostly about concrete answers: hours, a licence class, a way of calling when things go wrong. Show up ten minutes early, answer short and specific, and leave with your own answers too.

Frequently asked questions

What questions should you ask at the end of an interview?

Ask about the hourly rate and payday, the average number of hours, whether travel time between clients is paid, who supplies protective equipment and how training works. Two or three specific questions are enough to show you're serious.

How do you answer the salary question in an interview?

Give a realistic range, based on your experience and on job ads in your trade and region. The floor is the minimum wage, $16.60 an hour in Québec since May 1, 2026. Avoid "I don't know": it leaves the employer to set the number alone.

Can an employer ask my age in an interview in Quebec?

Québec's Charter of human rights and freedoms prohibits asking for information on grounds of discrimination, including age, during an interview, except as provided in the Charter. You can politely ask how it relates to the job. For a specific case, the Commission des droits de la personne et des droits de la jeunesse can inform you.

Does a trial day have to be paid?

Under the Act respecting labour standards, an employee is deemed to be at work during any trial or training period required by the employer. That time must therefore be paid, at least at minimum wage. For a particular situation, check with the CNESST.

How do you prepare for an interview with no experience?

Focus on reliability: clear availability, a way to get to work, licences and cards, and examples from other settings, such as a student job or volunteering. Also say what you're ready to learn. In the service trades, attitude often opens the door.
