You've sent off your resume, the recruiter called, and now you've got an interview for a FIFO role. Great — but mining interviews aren't like normal job interviews. They're heavier on safety, more specific about competencies, and they'll test whether you actually understand site life.
This guide covers the 20 most common FIFO interview questions, why they're asked, and how to answer them properly. Whether you're going for a haul truck operator gig, a diesel fitter role, or a site supervisor position — these questions come up again and again.
Safety Questions
Safety is the number one priority on every mine site in Australia. Expect at least a third of your interview to focus on it. Interviewers want to know you won't be the person who causes a lost time injury.
1. "Tell me about a time you identified a safety hazard on site."
Why they ask: They want to see you're proactive about safety, not just compliant.
How to answer: Use the STAR method (Situation, Task, Action, Result). Describe a specific hazard you spotted — a damaged sling, an unmarked excavation, a missing barricade. Explain what you did: stopped work, reported it, filled out a hazard report. Mention the outcome.
Example: "During a pre-start on a Komatsu 830E, I noticed hydraulic fluid leaking from a hose fitting on the steering circuit. I immediately tagged the truck out of service, reported it to the supervisor, and completed a hazard report. The fitters replaced the hose before the next shift. If it had failed during operation, it could have caused a loss of steering — serious risk on a loaded haul road."
2. "What would you do if you saw a workmate doing something unsafe?"
Why they ask: They're testing whether you'll speak up or stay quiet to keep the peace.
How to answer: Be direct. You'd approach them, have a conversation, and if needed escalate to the supervisor. Don't say you'd ignore it. Don't say you'd go straight to management without talking to them first.
3. "What's your understanding of a JHA/SWMS?"
Why they ask: They want to know you understand safe work documentation, not just that you've heard the acronyms.
How to answer: A Job Hazard Analysis identifies the risks in each step of a task. A Safe Work Method Statement outlines how the work will be done safely. Mention that you review them before every job, sign on, and speak up if conditions change from what's documented.
4. "Describe your LTI record."
Why they ask: Your lost time injury record is your safety track record. They want clean numbers.
How to answer: State your record clearly: "Zero LTIs across X years." If you've had an incident, be honest about what happened, what you learned, and what you do differently now. Never try to hide it — they'll find out during reference checks.
5. "What does 'Stop Work Authority' mean to you?"
Why they ask: Every worker on an Australian mine site has the right — and the obligation — to stop work if they believe it's unsafe.
How to answer: Explain that every person on site has the authority to stop work without repercussion if they identify an immediate risk. It's not just a right, it's an expectation. Give an example of when you've used it or would use it.
Behavioural Questions
These questions assess how you handle real situations. The interviewer is looking for evidence, not theory.
6. "Tell me about a time you worked in a high-pressure situation."
How to answer: Pick a specific example — a breakdown during a shutdown, a tight deadline, bad weather conditions. Focus on what you did, how you stayed calm, and the result. FIFO work is full of pressure, so they want to see you handle it well.
7. "How do you handle conflict with a workmate?"
How to answer: On site, you're living and working with the same people for weeks. Conflict is inevitable. Show that you address issues directly but respectfully — a quiet conversation, not a blow-up in the crib room. Mention that you'd involve the supervisor if it couldn't be resolved between you.
8. "Describe a time you had to adapt to a change in plans."
Why they ask: Plans change constantly on mine sites. Weather, breakdowns, priority shifts. They want someone who rolls with it.
How to answer: Give a concrete example. Maybe a shutdown scope changed overnight, or you were reassigned to a different area mid-swing. Show flexibility and a positive attitude.
9. "Why do you want to work FIFO?"
How to answer: Be honest and practical. It's fine to mention the money and roster — everyone does FIFO for the lifestyle benefits. But also mention that you enjoy the work, the team environment, and the challenge. Avoid saying "because I need the money" as your only reason.
10. "Tell me about a time you went above and beyond."
How to answer: This doesn't have to be heroic. Maybe you stayed back to finish a job properly, mentored a new starter, or identified a more efficient way to complete a task. Show initiative without sounding like you're trying too hard.
Technical Questions
These vary by role, but here are the most common ones across trades and operations.
11. "Walk me through your pre-start inspection process."
Why they ask: Pre-starts are non-negotiable. They want to know you do them properly, every time.
How to answer: Describe your routine in detail. For operators: walk-around, fluid levels, tyre condition, lights, mirrors, seatbelt, radio check, GPS, payload system. For trades: tool inspection, PPE check, work area assessment, energy isolation verification.
12. "What equipment/machinery are you experienced with?"
How to answer: Be specific. Don't say "trucks" — say "CAT 789D, CAT 793F, Komatsu 830E." Don't say "excavators" — say "Liebherr R9800, Hitachi EX5600." Specific model numbers show real experience. Mention hours if you have them.
13. "What tickets and licences do you hold?"
How to answer: List them clearly: trade certificate, MR/HR/HC licence, Working at Heights, Confined Space, Gas Test Atmospheres, First Aid, White Card, Elevated Work Platform, dogging, rigging. Mention expiry dates if they're current. If any are due for renewal, mention that you've already booked the refresher.
14. "How do you approach an isolation/LOTO procedure?"
Why they ask: Energy isolation is critical for trades roles. Mistakes can be fatal.
How to answer: Walk through the process: identify all energy sources, obtain a permit, apply personal locks and tags, test for dead, verify isolation before starting work, remove locks in reverse order when complete. Mention that you never remove someone else's lock.
15. "Describe a complex fault you've diagnosed."
How to answer: For trades: pick a fault that required systematic troubleshooting. Describe your diagnostic process — visual inspection, reading fault codes, testing components, narrowing down the root cause. Show logical thinking. For operators: describe a machine behaviour you identified early before it became a breakdown.
Situational Questions
These test your judgement and decision-making in hypothetical scenarios.
16. "You notice a crack in a structural component during an inspection. What do you do?"
How to answer: Stop work, tag the equipment out of service, report to your supervisor immediately, complete a hazard/defect report. Don't try to assess whether it's "bad enough" to worry about — that's for the engineers to decide.
17. "Your supervisor asks you to complete a task you haven't been trained for. What do you do?"
How to answer: You tell them. Politely but clearly: "I haven't been trained or signed off on that task." Offer to do it under supervision or ask for the training. Never bluff competency on a mine site — it's how people get hurt.
18. "You're running behind schedule on a job. What do you do?"
How to answer: Communicate early. Tell your supervisor before you miss the deadline, not after. Explain what's causing the delay, suggest solutions, and ask for help if needed. Never cut safety corners to make up time.
19. "A new starter on your crew is struggling. How do you handle it?"
How to answer: Support them. Show them the right way, be patient, answer questions. Everyone was new once. Mention that you'd also flag it with the supervisor if the person's struggling with something that could be a safety risk.
20. "What would you do in a site emergency — evacuation alarm sounds?"
How to answer: Stop work, make your area safe, proceed to the muster point, sign in on the roll, wait for the all-clear. Don't go back for tools, don't drive your truck to the muster point — walk unless instructed otherwise. Mention that you'd account for anyone who was working with you.
Tips for Your FIFO Interview
Be specific. Vague answers kill interviews. "I'm a safe worker" means nothing. "Zero LTIs across 4 years on CAT 789D haul trucks" means everything.
Use the STAR method. Situation, Task, Action, Result. Structure your answers so the interviewer can follow your thinking.
Know the company. Spend 10 minutes on their website. Know what commodity they mine, where their sites are, and what their safety values are called (BHP has "Our Charter", Rio Tinto has "The way we work").
Dress appropriately. If it's a video call, business casual is fine. If it's in-person at a labour hire office, clean and neat is enough — you don't need a suit.
Ask questions back. "What does a typical shift look like?", "What's the roster?", "What's the team size?" Shows genuine interest.
Don't badmouth previous employers. Even if your last supervisor was terrible. Keep it professional.
Before Your Interview
Make sure your resume is actually getting past the ATS first. There's no point preparing for an interview you'll never get because your resume was auto-rejected.
