If you are applying for a job in a technical area, you may face technical questions at interview, as well as general questions on your skills, experience and motivation.
Technical questions can take several forms:
1) General, open questions. Here are some examples:
- Tell me about the project you are most proud of and what your contribution was.
- Give me an example where you have applied your technical knowledge in a practical way.
- Explain what you covered in a particular part of your course.
Your initial answer is likely to be followed up by more probing supplementary questions.
2) Questions on specific skills
- What practical techniques have you carried out?
- Can you write reports? What makes a good report?
- What development tools have you used?
- What languages have you programmed in?
- Describe the process for writing a piece of code, from requirements to delivery.
- What are important safety factors need to be considered when working in a lab?
- What do you consider when organising your work?
Focus your answer on the skills relevant to the position. Remember the ‘Context Action Result’ structure.
3) Testing your subject knowledge
- What are the general properties of plasma?
- What are the effects of radiation on spacecraft, and how could you overcome these?
- How do you calculate an orbit at a given altitude?

- How would you store 1 million phone numbers?
- How can you reduce the user’s perception of waiting when some functions take a long time?
- What is the application of a sparse matrix?
Keep to a basic answer, don’t make it too complicated.
4) Looking at your thinking processes/ innovation/ practical aptitude
