10 Car Mechanic Interview Questions and Answers

What types of car do you have experience working with?

Use this question to discover what specialist experience a Car Mechanic candidate has. Things to look for in an answer:

  • Experience working with classic cars, electric or hybrid vehicles
  • How long they have been working with these types of vehicle
  • How they apply technical and problem-solving skills to these specific car types
Example:

'I have five years of experience working with electric and hybrid vehicles. This has involved extensive work with electric batteries, high voltage electrical systems and the correct health and safety procedures for fixing them. I am also confident providing feedback to electric vehicle owners during checkups.'

What hand tools are you comfortable using?

This helps you to understand more about a candidate's practical hard skills. Things to look for in an answer:

  • Practical experience using a range of hand tools such as wrenches, screwdrivers, sockets, spanners
  • Explains how they would be used to fix or change mechanical parts
  • Demonstrates problem-solving skills
Example:

'My work has involved extensive use of hand tools. I have used wrenches to tighten and loosen bolts, including impact wrenches for unscrewing large bolts on wheels or torque wrenches to ensure a bolt is at the correct tightness. I consider which tool is relevant to the job on a case-by-case basis, looking at which components I am dealing with and whether I need leverage, force or grip.'

Do you have previous experience as part of a workshop team?

This helps you find out more about a candidate's ability to work effectively as part of a team. Things to look for in an answer:

  • Ability to collaborate on problem-solving tasks
  • Communication skills
  • Can ask for advice when required
Example:

'Yes, in my previous role as a junior car mechanic, I worked as part of a busy workshop team where we often collaborated on diagnosing and repairing complex issues. For example, we once had a vehicle with an intermittent electrical fault that wasn’t showing up on standard diagnostics. I worked closely with another mechanic where we shared our observations, tested components together and eventually traced the issue to a faulty sensor. It was a great example of how joint knowledge and positive collaboration can solve problems more efficiently.'

How would you supervise a more junior Car Mechanic?

This is a question to ask if you are looking to hire a Car Mechanic in a senior or managerial role. Things to look for in an answer:

  • Demonstrable experience supervising and training junior staff
  • Understanding of different learning styles
  • Knows how to instruct and provide demonstrations
Example:

'When training up junior Car Mechanics, I first establish what tasks they're able to complete under my supervision. We then practise working on these together, before moving onto more challenging and complex tasks. I encourage them to ask plenty of questions so that I know they understand how to proceed correctly with the task. I also adapt to different learning styles so that they are comfortable and in the best position to learn.'

How do you troubleshoot mechanical issues?

Use this question to identify a candidate's problem-solving skills. Things to look for in an answer:

  • Understands correct diagnostic procedures
  • Is proactive in solving a client's issues
  • Can communicate these issues sufficiently to the client
Example:

'When a mechanical issue comes up, I start with a visual inspection and ask the client about any symptoms like unusual sounds or warning lights. I then run a diagnostic scan and check relevant components manually. For example, a car once showed an engine warning light with no clear fault code. I picked up on a rough engine sound and traced the problem to a worn spark plug and damaged coil pack. After replacing them, the issue was resolved.'

If you needed to communicate an issue to a customer, how would you achieve this?

This question helps assess a Car Mechanic’s communication soft skills, particularly their ability to explain technical problems clearly and respectfully.

  • Clear and precise communication
  • The ability to explain technical issues in plain language
  • Actively listening to a client's response
Example:

'Once I have identified the issue through diagnostics, I will provide the client with an update. I explain clearly and thoroughly what the issue is, in non-technical language, making sure they understand what’s wrong, why it matters and what their options are. I always take time to answer their questions and check they’re happy to go ahead with the work. I also make sure the quote is clear and agreed before starting any repairs. I find this helps build trust and avoids misunderstandings later on.'

Can you explain how you've used computer software to diagnose an issue?

Use this question to find out about a candidate's information technology hard skills. Things to look for in an answer:

  • Ability to diagnose, repair and optimise these systems
  • Understanding of diagnostic software tools
  • Keeps knowledge of systems up-to-date and relevant
Example:

'I have up-to-date knowledge of and training in onboard computer systems. I have applied this experience through using diagnostic software to identify errors and work with my team to solve them. As computer systems are often updated, I work hard to make sure my knowledge of such systems stays fresh and current.'

What scheduling and organisational skills have you demonstrated in a workshop environment?

This question helps candidates demonstrate their organisational and time management skills. Things to look for in an answer:

  • Ability to plan and schedule client work using appropriate tools
  • Clear communication with clients about timings and updates
  • Commitment to meeting deadlines, even in a busy environment
Example:

'I use an online calendar and project management system to track all appointments and ongoing jobs. This helps me manage my time effectively, especially on busy days when I’m balancing diagnostics, repairs and follow-ups. I always confirm time slots with clients in advance, usually by text or email depending on their preference, and let them know straight away if there are any changes. I also prioritise urgent repairs or quick turnaround jobs without compromising longer-term tasks, which helps the workshop run smoothly.'

Explain how you have handled difficult maintenance work in the past

Use this question to identify a candidate's problem-solving skills under pressure. Things to look for in an answer:

  • Ability to handle stress effectively
  • A methodical approach to complex tasks
  • The ability to seek advice from others or ask for a second opinion
Example:

'One of the more challenging jobs I handled was a full engine rebuild. It required careful disassembly, detailed inspection of each part and reassembly to ensure everything ran smoothly. I managed my time carefully and double-checked key steps along the way. When I encountered a stage I wasn’t fully confident about, I asked a senior team member to review it with me. Getting a second opinion helped me avoid potential issues and complete the job to a high standard. The vehicle ran perfectly after the rebuild, and it was a great learning experience.'

How would you conduct a risk assessment in the workshop?

This question helps you assess a candidate’s understanding of workshop safety protocols and their ability to identify and manage risks effectively. Things to look for in an answer:

  • First-hand experience of conducting or assisting with risk assessments
  • Ability to identify different types of risk (e.g. mechanical, chemical, environmental)
  • Understanding of how to implement and review safety measures
Example:

'First, I’d identify potential hazards in the workshop, such as moving vehicles, machinery, noise levels or exposure to chemicals. I’d assess each one based on how likely an accident is to occur and how serious the consequences could be. Then I’d record this and decide on any control measures needed, such as improved signage, PPE or changes to workshop layout or procedures. I’d also make sure the team is aware of the risks and the steps we’re taking to reduce them. Finally, I’d review the assessment regularly or after any incidents to make sure it stays up to date.'
