Prescreen questions for maintenance technician candidates

Ask these on a five-minute phone call or send them as a form before you book interviews.

  1. Are you legally entitled to work in Canada? (Yes / No)
  2. Which days and times are you available to work?
  3. When could you start?
  4. What pay are you looking for?
  5. What interests you about this job?
  6. What maintenance experience do you have (mechanical, electrical, pneumatics, hydraulics or building systems)?
  7. Do you hold a certificate or apprenticeship in a related trade, like millwright or electrician? (Certified / Apprentice / No)
  8. This role includes climbing ladders, working from lifts and getting into tight spaces around machines. Can you do that, with or without accommodation? (Yes / No)

How to score the answers

  1. Ask every candidate the same questions in the same order. That's what makes scores comparable.
  2. Write down what they did, not your impression. "Closed alone on a Saturday and restocked for the morning" beats "seems reliable".
  3. Score each answer from 1 to 5 against the guide under the question. A 3 is a solid, acceptable answer.
  4. Average the scores and read the notes behind any big gap between interviewers.
  5. Check references on the areas where you're least sure.

Questions to avoid

Hiring questions should be about the job. Human rights law in every province and territory protects people from being treated differently because of things like age, family status, disability, religion, race, place of origin, sex, sexual orientation, and gender identity. The list of protected grounds differs a little by province, so check yours.

Stay away from questions like these:

  • "How old are you?" or "When did you finish high school?"
  • "Do you have kids?" or "Are you planning a family?" The Ontario Human Rights Commission says an employer cannot ask whether an applicant is pregnant or plans to have a family.
  • "Where are you from originally?" You can ask: "Are you legally entitled to work in Canada?"
  • "Do you have any health problems?" You can ask: "This job involves [a real duty]. Can you do that, with or without accommodation?"
  • "What do you make now?" Nova Scotia and Prince Edward Island do not allow employers to ask about pay history. Asking what pay the person expects is fine.
  • Questions about the hours a person can work that mention family or religious commitments. Ask only whether they can work the hours the job needs, and state those hours.

Criminal record and driving record: wait until you have made a conditional offer, and ask only for what the job needs. Manitoba and Newfoundland and Labrador guidance says to wait until a conditional offer. Quebec's rights commission says a conviction counts only if it is connected to the job. Ontario's commission says you may ask only about convictions that have not been pardoned, and that a driver's licence number or copy may be requested only after a conditional offer and only if relevant.

This is general information, not legal advice. Rules differ by province. Human rights bodies: see the official sources.

Rules that differ by province. Ontario (25 or more employees), British Columbia and Prince Edward Island require the pay or a range in public job postings. Nova Scotia and Prince Edward Island do not allow pay-history questions. Ontario employers with 25 or more employees must tell each interviewed applicant within 45 days whether a hiring decision was made. Unpaid trial shifts that involve real work are not allowed in Ontario, British Columbia or Alberta. See hiring rules by province, checked 7 October 2026.

Questions

What should I ask in a maintenance technician interview?

Ask about the parts of the job that matter most: problem solving, safety and care, attention to detail, organizing and time management, plus role-specific questions such as "Walk me through how you'd troubleshoot a conveyor that stops at random times during the shift." Ask every candidate the same questions so you can compare them fairly.

How do I score a maintenance technician interview?

Score each answer from 1 to 5 against a short guide that describes a weak, solid and strong answer. Score what the person actually did in their example, not how confident they sounded. Then average the scores and read the notes behind any big differences.

What should I ask before interviewing a maintenance technician?

Use a short prescreen: work eligibility, availability, start date, pay expectations and the must-haves for the role, such as "What maintenance experience do you have (mechanical, electrical, pneumatics, hydraulics or building systems)?" Ask what pay the person expects, not what they earn now: Nova Scotia and Prince Edward Island do not allow pay-history questions.
