Interviews aren’t box-ticking exercises. Not only are they where you prove you can do the job – but they’re also for you to assess and confirm whether the job is right for you. This guide gives you the practical steps and checks so that you can walk into that interview feeling prepared, confident, and in control.

INTERVIEW PREPARATION
1. Do Some Proper Research
Good prep stops you being caught off-guard and helps you tailor your answers so you sound like someone who already understands the environment.
This is what we mean by ‘proper’ research:
Research the Company
Be clear on:
- What they manufacture
- Their processes & equipment
- Company values or priorities (safety, CI, investment, shift stability)
Strong research does three things:
✔ Shows enthusiasm
✔ Helps you avoid generic answers
✔ Gives you better questions to ask
Review the Job Clearly
If the job spec is vague, your interview is your chance to get clarity. If you can’t find these answers beforehand, ask them:
- “What’s the mechanical vs electrical split day-to-day?”
- “How old is the plant? Any legacy kit?”
- “Team size? Longevity?”
- “What’s the environment like – pace, breakdown levels, culture?”
Knowing this lets you show alignment or quickly spot if it’s not the right fit.
Understand the Interview Format
Maintenance interviews often involve:
- A technical test
- A site tour
- A chat with engineering or operations leadership
To prepare:
- Brush up on fundamentals you haven’t used recently
- Bring PPE (look prepared, not surprised)
- Pre-draft a few examples you want to land
Make sure you know the format before you arrive.
2. Dress for the Job (& be ready for a tour)
Engineering interviews aren’t corporate interviews. Aim for professional but practical: smart trousers, collared shirt or 1/4 zip, and keep some clean boots in the car in case of a tour.
Top tip from hiring managers:
Wear trousers you can comfortably put safety boots over! If they like you, you’ll be taken around site.
3. Avoid the Common Pitfalls
Complacency
It’s a candidate-heavy market and many engineers assume they’ve “got it”. That’s where people slip up. Treat every interview with full intent.
Nerves
If you haven’t interviewed in years, nerves spike. Preparation is your safety net.
Punctuality
- Know exactly where you’re going
- Factor in traffic
- Be early, not “on time”
- If anything goes wrong, communicate fast.
DURING THE INTERVIEW
1. How to Present Yourself
Attitude
Hiring managers want engineers who’re:
✔ Calm
✔ Professional
✔ Polite
✔ Engaged
–
Avoid coming across as:
✘ Cocky
✘ Negative
✘ Desperate
Body Language
Small behaviours do heavy lifting:
- Smile
- Maintain eye contact
- Sit open, not defensive
The best candidates come across confident but curious.
2. Questions You’ll Likely Get
Scenario-Based
These reveal your thinking process:
- “Talk me through a difficult breakdown – step by step.”
- “How do you fault-find logically?”
- “How would you handle a safety incident?”
- “Describe working with a difficult team member.”
Qualifications & Skills
Expect:
- “What qualifications do you hold?”
- “What skills make you effective on shift?”
- “Tell me about a time you overcame a technical problem.”
Experience-Specific
For example:
- “What environments have you worked in?”
- “Used heavy plant? Fast-moving lines? Legacy equipment?”
- “Worked shifts? Call-outs?”
3. How to Answer Well
Use STAR
It keeps your answers concise and shows your impact.
Situation, Task, Action, Result.
Other ways to strengthen your answers:
- Be confident, not arrogant
- Take your time
- Make it conversational – engineers often hire engineers based on chemistry
- Reference their machinery, processes or environment where possible
- If you lack a skill, position it as: “I’ve not worked with that, but I’ve worked with this, and the learning curve will be short.”
4. Skills to Show Off (Even if you’re not asked about these directly)
Hiring managers look for:
- Solid understanding of equipment & systems
- Reactive vs planned mindset
- Fault-finding logic
- Safety awareness
- Communication
- Prioritisation
- Adaptability
- Attention to detail
- Ownership under pressure
Make sure these come through in stories, tone, and examples.
5. Questions You Should Ask
Good engineers ask good questions – it shows long-term thinking.
Examples:
- “Where are your biggest pain points right now? What would you expect me to improve?”
- “What’s the reactive vs planned split?”
- “What’s the long-term investment plan for the site?”
- “Where do you want the business to be in 3–5 years?”
Why this matters:
✔ Shows you think long-term
✔ Signals stability
✔ Differentiates you from job-hoppers
6. Closing the Interview Strongly
Before you leave, confirm you’ve:
✔ Proven you can do the job
✔ Demonstrated you understand their environment
✔ Shown interest in the role, not any role
Two powerful closing questions:
- “Is there anything else you’d like me to expand on?”
- “Is there anything further I can demonstrate to show I’m the right fit?”
NEXT STEPS

Trust your instincts – they’re often right.
