Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Walk me through a time you diagnosed a problem on a building automation system that wasn't giving you a clear answer. How did you track it down?
What they are checking: real troubleshooting method versus parts-swapping, and comfort with BAS tools
Tell me about a time you had to keep a critical system running while waiting on parts or a contractor. How did you bridge that gap?
What they are checking: resourcefulness and risk management when a permanent fix isn't immediately available
Describe your experience with pneumatic tube systems or other specialty hospital systems you haven't worked with much before. How do you get up to speed fast?
What they are checking: willingness and ability to learn unfamiliar systems since not every tech comes in knowing every hospital-specific system
Tell me about a time you disagreed with another trade or a supervisor about how to handle a repair. What happened?
What they are checking: communication and conflict resolution in a multi-trade environment
Tell me about a time you had to work around live electrical or mechanical hazards. What precautions did you take?
What they are checking: genuine safety habits and lockout/tagout discipline, not just textbook knowledge
What would you do
This is a hospital. If you get an alarm on a medical gas or vacuum system in the middle of a shift, what's your first move?
What they are checking: understanding that patient safety systems get immediate, procedure-driven response, not casual triage
You're on call at 2am and a generator fails to transfer during a test. Nobody else is on site yet. What do you do?
What they are checking: judgment under pressure, escalation awareness, and whether they understand emergency power's stakes in a hospital
How do you decide what to fix yourself and what to escalate, especially working with minimal oversight?
What they are checking: independent judgment and knowing the limits of their own authority or skill
This role covers weekend second shift and on-call rotation. How have you managed off-hours emergency work in the past, and what makes you comfortable with this schedule long term?
What they are checking: realistic fit with the shift pattern and 24/7 coverage demands, not just polite agreement
About the work
Tell me about a steam boiler or chiller plant issue you handled. What was going on and what did you do first?
What they are checking: hands-on experience with critical central plant equipment and whether they prioritize safety steps first
How do you read a set of Life Safety drawings, and can you tell me about a time you actually used one to figure out a repair or a fire/smoke barrier issue?
What they are checking: real fluency with blueprints and life safety compliance, not just claiming to know it
What compliance codes or standards do you keep in the back of your mind day to day on a job like this - things like Joint Commission, NFPA, or similar?
What they are checking: whether they actually operate with regulatory awareness versus just doing repairs blind to code
What's your approach to preventive maintenance scheduling on complex mechanical, electrical, and plumbing systems so things don't turn into emergencies?
What they are checking: whether they think proactively versus reactively about facility upkeep
