Facilities Technician interview questions and how to answer them

A facilities tech interview is mostly a test of how you think when something breaks. Hiring managers want to hear you walk through a real repair, keep people safe and know where your skills stop. Here's what each round looks for and how to answer the questions you're most likely to get.

11 questions6 minute read

Part 1

1.A tenant says their office is too hot. Walk me through what you'd do.

Why they ask

This is the most common call in the job, and it shows whether you troubleshoot in a logical order or start swapping parts.

How to answer

  • Start with the easy checks: the thermostat setpoint, whether it's the only room, and whether someone blocked a vent
  • Look at the building automation system for the zone's readings, damper position and alarms
  • Check the VAV box or fan coil serving that space, then the air handler if several zones complain
  • Close the loop with the tenant and log what you found in the CMMS

2.You have a leak, a stuck elevator report and a broken door badge reader all at once. What do you do first?

Why they ask

Facilities work is constant triage. They want to see that you rank by safety and damage, not by who's yelling loudest.

How to answer

  • Confirm the elevator situation first, since a trapped person is a life safety issue, and call the elevator vendor or emergency line
  • Shut off water to the leak to stop the damage, even if the full repair waits
  • Tell your supervisor and security about the badge reader so someone can cover the door
  • Update the tickets so everyone knows the order and why

3.Tell me about your experience with preventive maintenance.

Why they ask

A building that only gets reactive repairs costs a lot more to run. They want someone who takes the scheduled work seriously.

How to answer

  • Name the equipment you've maintained, like rooftop units, pumps, boilers or emergency generators
  • Describe the actual tasks: filter changes, belt checks, greasing bearings, testing the generator under load
  • Mention the system you logged it in, such as Maximo, eMaint or UpKeep
  • Give an example of a PM check that caught a problem early
4.How do you handle lockout/tagout?

Why they ask

Someone gets hurt when a tech skips it. This question weeds out people who treat safety as paperwork.

How to answer

  • Walk through the steps: notify, identify every energy source, shut down, isolate, apply your lock and tag
  • Verify zero energy with a meter or by trying the start button before touching anything
  • Mention stored energy like capacitors, springs and pressurized lines
  • Say you'd stop the job if the procedure for that equipment isn't clear
5.What kind of electrical work are you comfortable doing?

Why they ask

They need to know where your skills end, both for safety and because some work legally needs a licensed electrician in their state.

How to answer

  • List what you've done yourself: replacing ballasts and LED drivers, outlets, switches, resetting breakers
  • Say what you've helped with but wouldn't do alone
  • Name what you'd hand to a licensed electrician, like panel work or new circuits
  • Mention the tools you use, such as a multimeter and non-contact voltage tester

Part 2

6.Tell me about a repair that took you longer than it should have.

Why they ask

Everyone has one. They want to see whether you learn from it or blame the equipment.

How to answer

  • Pick a real example, like chasing an intermittent fault in a pump controller
  • Say what slowed you down, maybe skipping a basic check or missing a manual
  • Explain what you do differently now
  • Keep it short and own it
7.How do you work with outside vendors and contractors?

Why they ask

A lot of your day is escorting, checking and signing off on vendor work. Bad oversight means paying for jobs that weren't done.

How to answer

  • Describe meeting them on site and making sure they have access and a clear scope
  • Check their work before signing the ticket, not just their paperwork
  • Push back politely when something's missed
  • Keep notes in the CMMS so the next visit starts from facts
8.Have you worked with a building automation system?

Why they ask

Most modern buildings run HVAC through a BAS, and techs who can read it fix comfort calls much faster.

How to answer

  • Name the platform if you've used one, such as Johnson Controls Metasys, Honeywell or Siemens Desigo
  • Describe what you did: read trends, acknowledge alarms, override a setpoint
  • Be honest about what you haven't done, like programming sequences
  • If you haven't used one, describe how you'd learn it quickly
9.How do you deal with an upset tenant or employee?

Why they ask

You're the face of facilities. A tech who's rude on a hot day creates complaints that land on the manager's desk.

How to answer

  • Listen first and repeat back what they told you
  • Give a realistic time you'll be back and keep it
  • Explain the fix in plain words when it's done
  • Use a short example from a past job
10.Are you comfortable with on-call and after-hours emergencies?

Why they ask

Buildings break at night and on weekends. They need to know you'll pick up the phone.

How to answer

  • Answer directly about your availability
  • Describe a past after-hours call and how you handled it
  • Mention how you judge whether something can safely wait until morning

Part 3

11.Why do you want to work in facilities instead of for a contractor?

Why they ask

They want to know you'll stay, and that you understand in-house work is broader and more people-facing.

How to answer

  • Mention wanting to know one building deeply instead of driving between jobs
  • Say you like working across trades
  • Tie it to something specific about their site, like a hospital or a campus

Questions to ask them

Ask at least two. It shows you're picking them too.

  • What does the on-call rotation look like, and how often does it actually get called?
  • Which CMMS do you use, and how far behind is the preventive maintenance backlog?
  • What work do you keep in-house, and what goes to contractors?
  • Who would I shadow in my first weeks, and what systems would I learn first?
  • What's the oldest equipment in the building that keeps you up at night?
