Mechanical Engineering Apprentice Interview Questions UK: 8 Real Questions and What Interviewers Want

Applying for a Mechanical Engineering Apprentice job in the UK? Here is what you are likely to be asked. These questions come from our Mechanical Engineering Apprentice question bank of 16 questions, written for UK employers at apprentice/entry level.

Eight Mechanical Engineering Apprentice interview questions, and what the interviewer is thinking

1. Why do you want to do a mechanical engineering apprenticeship rather than go to university, and what do you expect a typical week to involve?

Why they ask: They want to see that you understand what an apprenticeship demands and that you are choosing it for good reasons.

2. What safety rules and personal protective equipment would you expect to follow in an engineering workshop, and what would you check before using a machine?

Why they ask: Safety is the first thing apprentices are assessed on, since mistakes in a workshop can cause serious injury.

3. Tell me about a time you made or repaired something practical and had to solve a problem along the way.

Why they ask: They are looking for evidence of practical aptitude and persistence, since apprentices are often hired on potential.

4. How would you use and read a micrometer and a vernier caliper, and how would you make sure your measurement is reliable?

Why they ask: Accurate measurement is the foundation of all engineering work, so they test it directly.

5. What are the main things you would look for on an engineering drawing before starting to make a part?

Why they ask: They want to know whether you can read a drawing, which underpins every workshop task.

6. Your supervisor gives you a task and you realise you're not sure how to do it. What do you do?

Why they ask: They want to see you ask for help appropriately rather than hide uncertainty or take risks.

7. What is the difference between mild steel, stainless steel and aluminium, and where might you use each?

Why they ask: They want to check your basic materials knowledge and its practical application.

8. What is the difference between what a lathe and a milling machine do, and what do you know about setting up a workpiece safely?

Why they ask: They want to see basic machining knowledge and a safety-first approach to workholding.

A sample answer to question 1

Why do you want to do a mechanical engineering apprenticeship rather than go to university, and what do you expect a typical week to involve?

I prefer learning by doing, and an apprenticeship lets me earn while I build real skills alongside experienced engineers, rather than only studying theory. I also want to gain a recognised qualification, such as a Level 3 Engineering Fitter or Machining Technician apprenticeship standard, with the option to progress to a higher or degree apprenticeship later. As I understand it, a typical week would mix time in the workplace, working with different teams in the workshop, maintenance or production areas, and a day or block release at college, learning maths, engineering science, drawing and the theory behind the practical work. I'd expect to start with safety, hand skills and measuring, then move to machining, assembly and fault finding under supervision. I'd also be keeping a portfolio of work for my end-point assessment. I like that it lets me test the job properly, and I know it takes commitment, punctuality and willingness to learn from everybody.

Common mistake to avoid: Saying you only want to avoid university debt; not knowing anything about the structure of an apprenticeship
