Common engineering interview questions and answers
So, your CV made it to the shortlist and you have an interview lined up for a job at an engineering firm. Doing well in an interview is all about preparation – so spend a few hours beforehand planning your answers to common engineering job interview questions.
- As part of your prep, sit down with the job spec itself and come up with examples of how your skills and experience are relevant to the requirements listed. For instance, if it’s an aerospace engineering role, make sure to highlight your experience using CAD for developing engine specifications, or the extensive hours you’ve spent in the testing lab.
- Even if you don’t have direct examples or a lot of experience, think laterally. Perhaps you haven’t dealt with clients in a technical engineering context before, but instead can point to your communication and interpersonal skills developed in previous roles to show the employer you have the aptitudes required.
- It’s also essential to brush up on the business you’re applying to and the sector more widely. Browse their website and get to know the company’s history, values and place in the market. The same goes for reading more widely about the sector – find out who their local and national competitors are and skim through the trade press to get to a feel for industry trends.
- If you’re looking to progress to a higher position, you may not have experience in every aspect of your desired job. This isn’t necessarily a problem, as long as you can show you’re being proactive about it. Say you don’t have budgeting experience – perhaps sign up to an online course to get your head around the essentials.
Types of engineering job interview questions
Whether you work in aerospace or automotive, railways or oil rigs, you’ll almost certainly be asked the following kinds of questions:
- Generic engineering interview questions: These aim to work out what you’re looking for and why you want to work for the business – e.g. Why do you want to work in the wind energy sector?
- Specific questions about the role: These questions aim to probe your technical knowledge – e.g. Share an experience in which you oversaw the assembly of a field of wind turbines.
- Scenario based questions: These aim to judge whether you’re a good fit for the company. – e.g. What would you do if your client set a deadline that you felt compromised project safety?
- Strengths-based questions: These are looking to find out about your personal traits – e.g. How do you keep organised? What method do you use for managing your workload?
Here are some common types of engineering interview questions to help with your preparation.
Company knowledge questions
Example: "Why do you want to work for us?"
- What the interviewer is really asking: They’re looking to find out what you know about their business, why you’ve chosen to apply to them over their competitors and how this job fits into your career trajectory. Be sure to focus on why them and not why you want to work in the industry in general.
- Example response: I’ve followed your company for a few years now and have been impressed by your work, especially your 2013 breakthrough in turbine efficiency. I am keen to work for an international firm that has the size to really tip the balance in favour of clean, green power – an area that I believe is the future of energy.
Sector knowledge questions
Example: "What are the big challenges for the wind sector in the coming years?"
- What the interviewer is really asking: They want to know if you understand the sector and have done your homework – ultimately, they want to hire someone who cares about the industry and understands future opportunities and risks. Be sure to show that engineering is a passionate interest and not just a job to you!
- Example response: There are some important challenges on the horizon, most specifically, many governments are reducing subsidies for the wind sector, meaning revenue is lower than it once was.
Specific role-related questions
Example: "Describe the process of laying a wind turbine on the ocean floor"
- What the interviewer is really asking: They want to see evidence that you have basic technical knowledge of the field. Show them that, if sent out to a work site tomorrow, you’d be able to handle yourself.
- Example response: You would describe the process of piling a wind turbine into the sea floor and installing the blades. Go into as much technical detail as you can, citing where relevant real-world experiences and potential pitfalls to avoid.
Problem solving questions
Example: "You are charged with laying a new wind farm in an offshore location but discover that preparatory work has missed that some parts of the seabed are unstable. What do you do?"
- What the interviewer is really asking: They want to see how you think when you discover a problem – what’s your step-by-step process for resolving such a situation?
- Example response: I would call together a meeting of the engineering team and carry out an assessment of the delay this issue would cause. I would then contact the customer to explain the situation and provide estimates of the delay and potential solutions to the problem.
Personal attribute questions
Example: "How do you cope when given a tight deadline?"
- What the interviewer is really asking: They want to get a feel for the ‘real’ you and see how you react under stressful circumstances. They want to hear how you’ll cope on both a practical and personal level.
- Example response: Tight deadlines are a challenge for anyone, so I try and take a practical approach. As an immediate first step I look at my workload and work out which tasks form part of the project’s critical path, which can be pushed back, and which can be delegated. From there I develop a step-by-step plan for completion of the project, ensuring that the client is informed about the situation and what will be needed from them to progress.
The key is keeping a clear head. Tight deadlines are part of the job, so you can’t panic. Stay focused, plan carefully and work closely with the rest of the team.
Experience questions
Example: "Tell us about a time when you discovered a critical fault in a product that required emergency action."
- What the interviewer is really asking: They want to learn how you react to problematic situations. Again, they want to know what you do on a technical level, but also how you keep your cool under pressure.
- Example response: In 2014, I was the sub-project manager on a land installation in Yorkshire. We discovered that three of the turbines had a critical technical fault. My first response was to follow the standard testing protocol the company had put in place. Once we discovered they still weren’t working, I reported to the project manager with a detailed report of the issue and presented possible solutions for consideration.
