Strength based interviews form part of the UK Civil Service Success Profiles framework and are used across most grades in England. From entry level AO and EO roles, through HEO to G7 professional posts, and into senior leadership and SCS appointments, Strength questions are now a routine part of assessment.Unlike Behaviour questions, Strength questions assess what energises you, how you naturally approach work, and whether you are a genuine fit for the role.
Many candidates underestimate Strength interviews because the questions feel simple. In reality, they are fast-paced, probing and carefully scored. Your enthusiasm, tone of voice and authenticity are assessed as closely as the content of your answer.
On this page, I explain how Strength based interviews work in the Civil Service, how they differ across grades, and how to prepare effectively.
What is a Strength based interview?
A strength is something that energises you. It feels natural and authentic. When you use a strength, you tend to perform well because you enjoy the activity itself.
Strength based interview questions are designed to uncover:
- What motivates you
- What comes naturally to you
- How you behave under pressure
- Whether your strengths align with the role
Under the UK Civil Service Success Profiles framework, Strengths sit alongside Behaviours and Experience. They are not personality tests and they are not trick questions. They are structured, assessed and mapped to the role profile.
Unlike Behavioural questions, Strength questions are usually shorter and more conversational. The panel may ask multiple follow-up questions quickly. They are looking for fluency, authenticity and energy as well as substance.
How Strength questions differ from competency questions
Candidates often struggle because they prepare for Strengths in the same way they prepare for Behaviours.
Behaviour questions usually require a structured STAR example.
Strength questions require reflection, self-awareness and natural explanation.
For example:
Behaviour question:
- Tell me about a time you managed a difficult stakeholder?
Strength question:
- What does a good day at work look like for you?
- When are you at your best?
- How do you respond when priorities change?
You may still draw on experience, but you do not deliver one long rehearsed story. Instead, you demonstrate natural alignment and enthusiasm supported by brief examples.
How Strength questions are used at different Civil Service grades
Strengths are used differently depending on grade and department.
EO and video interviews
At EO level, particularly in pre-recorded video interviews, strength questions may form the entire interview. Candidates often face multiple short strength questions with limited thinking time. Delivery and natural energy are critical.
HEO to G6
At these grades, panels often assess behaviours first. They may then say, “We are now going to ask you Strength-based questions.” These are typically asked at the end of the interview and scored separately.
Some panels will open the interview with an unscored strength-style question such as “What does a good day look like for you?” to gauge natural energy and communication style.
SCS, Deputy Director and above
At senior levels, Strength questions are often woven into the main interview discussion without signposting. Panels assess alignment, leadership energy and authenticity through integrated questions rather than clearly labelled strength questions.
Understanding this variation is important when preparing.
Common Strength based interview questions
Examples include:
- What does a good day look like for you?
- When are you at your best?
- How do others describe you?
- What motivates you?
- How do you react when plans change?
- What does a high-performing team look like to you?
Strong answers show:
- Self-awareness
- Alignment with the role
- Genuine enthusiasm
- Consistency between what you say and how you say it
Why candidates struggle with Strength interviews
Many capable candidates underperform in Strength interviews for three main reasons.
- They over-structure their answers and sound rehearsed.
- Yhey focus only on content and forget that tone, pace and expression are being assessed.
- Nerves suppress natural energy. Strength interviews reward authenticity. If anxiety flattens your delivery, you may score lower than your experience deserves.
Learning how to regulate nerves and communicate naturally is part of effective preparation.
How to prepare for Civil Service Strength questions
Preparation should focus on three areas:
- Analysing the job description and Success Profiles criteria
- Identifying your genuine strengths that align with the role
- Practising concise, natural answers with rapid follow-up probing
You should understand the difference between authentic strengths and learned skills. Panels are skilled at spotting rehearsed or exaggerated responses.
