Engineering Interview Guide (UK): Graduate, Mechanical, Civil and Electrical Engineering Interviews
Engineering interviews in the UK mix technical knowledge, project experience and the softer skills of working with clients, contractors and other disciplines. Whatever branch you are in, the same preparation habits work.
The typical process
Graduate schemes usually start with an online application and tests, followed by a video interview and an assessment day or final interview. Experienced hires often meet an engineering manager and a technical lead, and may present a past project.
Technical questions
The level depends on the role. A graduate might be asked about fundamentals from their degree, such as stress and strain, circuit theory, fluid mechanics or structural loads. An experienced engineer will be asked how they approached a specific design problem, which standards they used and how they checked their work. Be ready to sketch ideas on paper and explain your assumptions.
Talking about your projects
Choose two projects. For each, be able to describe the problem, your specific role, the technical decisions you made and why, what went wrong, and the outcome. Include numbers such as budget, loads, timescale and savings. If you worked in a team, be clear about which parts were yours.
Health and safety
Safety is central in UK engineering. Expect questions about risk assessments, CDM regulations in construction, method statements and what you would do if you saw an unsafe practice. The right answer is always that you would stop the work or raise it straight away, never to ignore it.
Professional registration
In the UK, many engineers work towards Incorporated or Chartered status through an institution such as the IMechE, ICE or IET. Employers value candidates who have a plan. If you are working towards it, mention what experience you have so far and who is mentoring you.
Behavioural questions
Tell me about a time you solved a technical problem under time pressure.
How do you handle a disagreement with a client or a colleague?
Describe a time you made a mistake in a design or calculation.
How do you keep your technical knowledge up to date?
Common mistakes
Memorising theory but being unable to apply it to a real situation.
Claiming a team project as entirely your own work.
Having no questions about the projects, team or development opportunities.
Quick answers
Do I need a degree to be an engineer in the UK? A degree is the usual route, but higher and degree apprenticeships are growing and are well respected.
What is chartership and is it worth it? It is professional recognition from an engineering institution, usually after several years of experience, and it often increases salary and responsibility.
