Engineering Technician Interview Questions UK: 8 Real Questions and What Interviewers Want

Before your Engineering Technician interview, it helps to see the questions from the interviewer's side. We have picked eight from our set of 16 and added the reason each one gets asked.

Eight Engineering Technician interview questions, and what the interviewer is thinking

1. Which measuring instruments have you used, and how do you make sure a measurement is accurate?

Why they ask: They want to confirm you can handle basic metrology and appreciate how errors creep in.

2. How do you read an engineering drawing, and what information would you check before starting a job?

Why they ask: Drawing interpretation is a fundamental skill, and errors here cause scrap and rework.

3. How would you use a multimeter safely to test a circuit, and what are the safety checks before you begin?

Why they ask: Electrical competence and safe working are essential for any technician, so they probe the basics.

4. Talk me through how you would approach finding a fault on a piece of equipment that has stopped working.

Why they ask: Fault-finding method matters more than guesswork, and they want to see a logical approach.

5. What precautions do you take when soldering or handling sensitive electronic components?

Why they ask: This checks your knowledge of workmanship standards and the damage static can do.

6. You are about to take a measurement and notice the calibration label on your micrometer expired last month. What do you do?

Why they ask: They are checking that you follow quality systems and do not take shortcuts.

7. Tell me about a time you diagnosed and fixed a fault on a piece of equipment or a prototype.

Why they ask: They want a real example of practical problem solving in a technician setting.

8. What does a typical day as an engineering technician involve, and what attracts you to it?

Why they ask: They want to make sure you understand the practical nature of the work and are suited to it.

A sample answer to question 1

Which measuring instruments have you used, and how do you make sure a measurement is accurate?

I have used vernier and digital calipers, micrometers, dial test indicators, height gauges, feeler gauges and a digital multimeter. Before measuring, I check the instrument has a valid calibration label and is not damaged, clean both the instrument and the part, and zero it. For a micrometer I check the zero with the anvils closed, and I use the ratchet so I apply a consistent force. I also let the part and instrument come to the same temperature, because a part fresh off a machine will be bigger than it will be when it cools. I read at eye level to avoid parallax, take more than one reading, and use the right tool for the tolerance: calipers are fine for plus or minus 0.1 millimetres, but for plus or minus 0.01 I would use a micrometer. I record readings straight away, with the instrument ID, so there is traceability. If a reading seems odd, I would recheck with a different instrument before reporting it.

Common mistake to avoid: Using out-of-date instruments; forgetting temperature effects
