DE&S Interview Tips

Congratulations, you’ve aced your application and have now been invited for interview. We’re keen to talk to you, so take the opportunity to impress by preparing well.

We conduct CV-based interviews, where you’re assessed against the criteria below and your fit to the DE&S Behaviours.

  • CV review (including key achievements, relevant experience, and applied skills and knowledge).
  • Core behaviours and technical competences (as stated in the job advert).

Find out more about the Core Civil Service Behaviours and Technical Competences aligned to each job profile.

So, sell yourself according to these criteria to give yourself the best chance of success.

Preparation is vital. DE&S’s director of HR Danny Griffiths says: ‘Approach interviews as you would an exam.’

Hints and tips

What to prepare

  • For an interview, you can never prepare too much. This includes knowing exactly where the interview is, how to get there and how long it takes factoring in traffic, parking, public transport routes and travel times.
  • Bring a copy of your CV with you, this will help to remind you of things you want to discuss.
  • Arrive early to avoid panic, but not so early that you have too much time in the waiting area to think and worry about your interview.
  • Have a mock interview. Ask a friend or family member to pretend to interview you so you have a chance to practise what you want to say.
  • Understand the job description and what are the key skills and experiences being asked for. Think about when you have delivered in these key areas, especially focusing on achievements and successes (consider the STAR technique to ‘paint a picture’) and ensure the panel really understands your efforts and recognises the outcomes you achieved.
  • Dress professionally in something you feel comfortable in. If you feel good, you’ll perform better! And avoid last minute panic by planning your interview outfit the night before.
  • Be sure to get enough sleep the night before. You will feel less nervous and more confident if you feel refreshed and rested.
  • Eat a good breakfast or lunch. Great interviews start with a great meal, and no one can provide good answers when their stomach is grumbling!
  • Give yourself a motivational talk! It’s not crazy to talk to yourself and it will give you an instant boost. Say things like “I’m qualified for this role! I’m confident and ready!”. Say it out loud and with confidence.
  • Use the toilet before you go in. You don’t want any distractions during the interview!

Understanding DE&S

  • The difference between a good interview and a great interview can be showing what you have researched about the organisation. Search this website to find out more about the work we do supporting the UK’s armed forces.
  • We will be looking for you to display how you fit in with our behaviours, consider these when explaining your experience:
    • We work as one team with our customer
    • We support one another
    • We are professional in everything we do
    • We are committed to getting better
    • We deliver on our promises – no excuses.

How to display interest

  • As the force behind the armed forces, our employees are passionate about the work we do and why we do it. Why do you want to work for DE&S? Consider how you will get this across.

CV based interview

  • The questions you are asked will be based around the evidence provided in your CV. We will be trying to ascertain not only your experience, but also that you have the right skills and how you have achieved past goals.
  • Consider the behaviours you demonstrated throughout and how these may tie in with those of DE&S and those asked for in the job advert.


  • Ensure you go to your interview prepared with questions you want answered.
  • Great questions will enable you to show further interest, understand the challenges of the role and sell other areas of strength accordingly.
