You’ve polished your CV, submitted your application, and now you’ve landed an interview. Brilliant! But here’s where many candidates stumble: the dreaded competency-based interview questions. These aren’t your typical “tell me about yourself” queries. They’re designed to dig deep into your past experiences, revealing how you’ve handled real situations and predicting how you’ll perform in the future.
If you’ve ever left an interview thinking, “I wish I’d said that differently,” you’re not alone. Research shows that over half of all candidates are rejected at the first interview stage, often because they haven’t properly prepared for competency-based questions. But here’s the good news: with the right preparation and techniques, you can transform these challenging questions into opportunities to showcase your brilliance.
In this comprehensive guide, I’ll walk you through everything you need to know about answering competency-based interview questions, from understanding what they are to mastering the techniques that’ll make you stand out from the crowd.
What Are Competency-Based Interview Questions?
Competency-based interview questions (also known as behavioural or situational questions) are designed to assess specific skills and abilities that employers have identified as essential for success in a particular role. Unlike traditional interview questions that might ask hypothetical scenarios (“What would you do if…?”), competency-based questions focus on your actual past experiences.
These questions typically begin with phrases like:
- “Tell me about a time when…”
- “Give me an example of…”
- “Describe a situation where…”
- “Can you walk me through an occasion when…”
The underlying principle is simple yet powerful: past behaviour is the best predictor of future performance. If you’ve successfully demonstrated a skill or competency before, you’re likely to do so again.
Why Do Employers Love Competency-Based Interviews?
Employers across industries have embraced competency-based interviewing for several compelling reasons:
Fairness and Consistency: Every candidate faces the same questions, reducing bias and creating a level playing field. This structured approach means your performance is judged against predetermined criteria rather than an interviewer’s gut feeling.
Evidence-Based Assessment: Rather than relying on vague impressions, interviewers can evaluate concrete examples of your skills in action. This makes the hiring process more objective and reliable.
Predictive Accuracy: Studies consistently show that behavioural interviews are among the most accurate predictors of job performance, far surpassing traditional interview methods.
Comprehensive Evaluation: These questions allow employers to assess multiple competencies simultaneously, from technical skills to soft skills like communication and teamwork.
According to recent data, approximately 51% of organisations now use competency-based interviews as their primary interview format, with this figure rising to over 70% among large graduate employers and multinational corporations.
The Core Competencies Employers Assess
Before diving into how to answer these questions, it’s crucial to understand what competencies employers typically look for. Whilst specific requirements vary by role and industry, certain core competencies appear consistently across most positions:
| Competency | What It Means | Common in These Roles |
|---|---|---|
| Communication | Ability to convey information clearly, listen actively, and adapt your message to different audiences | All roles, especially customer-facing positions, management, teaching |
| Teamwork | Collaborating effectively with others, contributing to group goals, and supporting colleagues | Project-based roles, healthcare, consulting, engineering |
| Problem-Solving | Analysing situations, identifying solutions, and implementing effective strategies | Analytical roles, IT, management, consulting |
| Leadership | Inspiring and guiding others, making decisions, and taking responsibility | Management positions, team leader roles, project management |
| Adaptability | Responding positively to change, learning new skills, and thriving in dynamic environments | Startups, fast-paced industries, technology sector |
| Decision-Making | Evaluating options, considering consequences, and making sound judgements | Senior positions, finance, healthcare, policy roles |
| Planning and Organisation | Setting priorities, managing time effectively, and coordinating resources | Administrative roles, project management, event planning |
| Commercial Awareness | Understanding business operations, market dynamics, and customer needs | Sales, marketing, business development, consulting |
| Resilience | Handling pressure, bouncing back from setbacks, and maintaining performance under stress | High-pressure environments, emergency services, healthcare |
| Initiative | Taking proactive action, identifying opportunities, and working independently | Entrepreneurial roles, research positions, senior management |
Understanding which competencies are most relevant to your target role is the first step in preparing winning answers. Always review the job description carefully and identify the key skills they’re seeking.
The STAR Technique: Your Secret Weapon for Competency-Based Interview Questions
Now we come to the game-changer: the STAR technique. This proven framework provides a clear structure for answering competency-based interview questions, ensuring your responses are comprehensive, compelling, and easy to follow.
STAR stands for:
S – Situation
Set the scene by briefly describing the context of your example. Where were you? What was happening? Who else was involved?
Top Tip: Keep this section concise (2-3 sentences maximum). You’re providing context, not writing a novel. Include enough detail for the interviewer to understand the scenario, but don’t get bogged down in unnecessary information.
T – Task
Explain what your specific responsibility or objective was in that situation. What were you trying to achieve? What challenge did you face?
Top Tip: Make it clear what YOUR role was, especially if you’re describing a team situation. The interviewer wants to know about your contribution, not just what the team accomplished.
A – Action
This is the most important part of your answer. Describe the specific steps YOU took to address the situation. What did you do? How did you do it? Why did you choose that approach?
Top Tip: Use “I” statements rather than “we” statements. Even in team situations, focus on your individual actions and decisions. This section should be the longest part of your answer, typically 50-60% of your total response.
R – Result
Share the outcome of your actions. What happened? What did you achieve? What did you learn?
Top Tip: Whenever possible, quantify your results with specific numbers, percentages, or measurable outcomes. Also, don’t forget to mention what you learned from the experience and how it’s shaped your approach since then.
STAR Technique in Action: A Complete Example
Let’s see how this works with a common competency question:
Question: “Tell me about a time when you had to work under pressure to meet a tight deadline.”
Situation: “In my previous role as a marketing coordinator at a digital agency, we secured a last-minute opportunity to pitch for a major client’s account. However, we only had 48 hours to prepare a comprehensive proposal that would normally take a week.”
Task: “As the lead coordinator, I was responsible for pulling together input from our creative, strategy, and account management teams, whilst ensuring we delivered a polished, professional proposal that showcased our capabilities.”
Action: “I immediately called an emergency team meeting to assess what we could realistically achieve in the timeframe. I broke down the proposal into manageable sections and delegated specific tasks based on each team member’s strengths. I created a shared project timeline with hourly milestones to keep everyone on track. To maximise efficiency, I arranged for team members to work in shifts, ensuring we had coverage around the clock. I also took on the role of quality controller, reviewing each section as it was completed and providing immediate feedback. When our graphic designer fell ill on the second day, I quickly sourced a freelancer from our network to ensure we didn’t lose momentum.”
Result: “We submitted the proposal 30 minutes before the deadline, and it was comprehensive, creative, and error-free. The client was so impressed with our responsiveness and the quality of our work under pressure that we won the account, worth £250,000 annually. This experience taught me the importance of clear communication, strategic delegation, and having contingency plans. I’ve since implemented a ‘rapid response’ protocol for similar situations, which has helped us secure three additional last-minute opportunities.”
Notice how this answer:
- Provides clear context without excessive detail
- Focuses on the candidate’s specific actions and decisions
- Demonstrates multiple competencies (leadership, organisation, problem-solving)
- Includes quantifiable results
- Shows learning and growth

Preparing Your Competency Examples: A Strategic Approach
Now that you understand the STAR technique and common questions, it’s time to prepare your own examples. Here’s a systematic approach:
Step 1: Audit Your Experience
Create a comprehensive list of your professional experiences, including:
- Significant projects you’ve led or contributed to
- Challenges you’ve overcome
- Achievements you’re proud of
- Situations where you demonstrated key skills
- Times when things didn’t go as planned and what you learned
Don’t limit yourself to paid employment. Relevant examples can come from:
- Volunteer work
- University projects and societies
- Internships and work placements
- Personal projects or side hustles
- Sports teams or community involvement
Step 2: Map Examples to Competencies
Review the job description and identify the 5-7 core competencies required for the role. Then, match your experiences to these competencies. Aim to have at least 2-3 examples for each key competency.
Pro Tip: Some examples can demonstrate multiple competencies. A single project might showcase your leadership, problem-solving, and communication skills simultaneously. These versatile examples are particularly valuable.
Step 3: Structure Your Examples Using STAR
For each example, write out the full STAR response. This might feel time-consuming, but it’s invaluable preparation. As you write:
- Be specific about your actions and decisions
- Include measurable results wherever possible
- Ensure the example is relevant to the competency
- Keep the overall response to 2-3 minutes when spoken aloud
Step 4: Practice, Practice, Practice
Once you’ve prepared your examples, practice delivering them out loud. This helps you:
- Refine your wording and pacing
- Identify areas that need more detail or less
- Build confidence in your delivery
- Ensure your examples sound natural, not rehearsed
Consider recording yourself or practising with a friend who can provide honest feedback. Pay attention to:
- Clarity and coherence
- Appropriate level of detail
- Natural delivery (not robotic or over-rehearsed)
- Time management (aim for 2-3 minutes per answer)
Advanced Strategies for Answering Competency-Based Interview Questions
Beyond the basics of the STAR technique, these advanced strategies will help you truly excel:
1. The Power of Specificity
Vague answers are forgettable. Specific details make your examples memorable and credible. Instead of saying “I improved team performance,” say “I implemented a new project management system that reduced missed deadlines by 40% and improved team satisfaction scores from 6.5 to 8.2 out of 10.”
2. Show Your Thought Process
Interviewers aren’t just interested in what you did, but why you did it. Explain your reasoning: “I chose to address the issue directly with my colleague rather than escalating to management because I believed it would preserve our working relationship whilst still resolving the problem.”
3. Demonstrate Growth and Learning
Always conclude your examples by reflecting on what you learned and how it’s influenced your approach since then. This shows self-awareness and continuous improvement: “This experience taught me the importance of setting clear expectations from the outset, which is why I now always begin projects with a detailed kick-off meeting.”
4. Be Honest About Challenges
Don’t be afraid to discuss situations where things didn’t go perfectly. Employers value candidates who can acknowledge mistakes, learn from them, and demonstrate resilience. The key is to focus on what you learned and how you’ve improved.
5. Tailor Your Examples to the Role
Whilst you’ll prepare core examples in advance, be ready to adapt them to the specific question and role. If you’re interviewing for a customer-facing position, emphasise the client interaction aspects of your examples. For a technical role, highlight the analytical and problem-solving elements.
6. Use the “So What?” Test
After preparing each example, ask yourself “So what?” Does your answer clearly demonstrate the competency? Does it show the impact of your actions? If not, revise to make the connection more explicit.
Common Mistakes to Avoid
Even well-prepared candidates can stumble. Here are the most common pitfalls and how to avoid them:
Mistake 1: Being Too Vague or General
The Problem: “I’m a good team player. I always work well with others and contribute to group projects.”
The Solution: Provide a specific example with concrete details about a particular situation, your actions, and the results.
Mistake 2: Focusing on “We” Instead of “I”
The Problem: “We completed the project ahead of schedule and under budget.”
The Solution: Whilst acknowledging team efforts, clearly articulate YOUR specific contribution: “I coordinated the team’s efforts by creating a shared timeline and conducting weekly progress reviews, which helped us complete the project two weeks early.”
Mistake 3: Rambling Without Structure
The Problem: Jumping between different aspects of the story without a clear narrative flow, leaving the interviewer confused about what actually happened.
The Solution: Stick to the STAR structure. If you find yourself going off on tangents, pause and refocus on the key points.
Mistake 4: Neglecting the Result
The Problem: Spending too much time on the situation and action but failing to clearly articulate the outcome.
The Solution: Always conclude with specific, measurable results. If you can’t quantify the outcome, describe the qualitative impact and what you learned.
Mistake 5: Using Hypothetical Examples
The Problem: “If I were in that situation, I would…”
The Solution: Competency-based questions require real examples from your past. If you genuinely don’t have a relevant example, be honest and explain how you would approach such a situation based on similar experiences.
Mistake 6: Choosing Irrelevant Examples
The Problem: Sharing an impressive story that doesn’t actually demonstrate the competency being assessed.
The Solution: Always ensure your example directly addresses the question asked. If necessary, explicitly state the connection: “This example demonstrates my problem-solving skills because…”
Handling Difficult Competency Questions
Sometimes you’ll face questions that catch you off guard or ask about experiences you don’t have. Here’s how to handle these challenging situations:
When You Don’t Have a Direct Example
If you’re asked about a situation you genuinely haven’t experienced, be honest but strategic:
“I haven’t encountered that exact situation in my professional experience. However, I did face a similar challenge when [describe related example]. Based on that experience, if I were to face the situation you’ve described, I would approach it by [explain your strategy].”
This demonstrates honesty, adaptability, and the ability to transfer learning from one context to another.
When Asked About Failures or Weaknesses
These questions can feel uncomfortable, but they’re opportunities to demonstrate self-awareness and growth. Choose an example that:
- Is genuine (interviewers can spot fabricated “weaknesses” a mile away)
- Isn’t a critical requirement for the role
- Shows how you’ve learned and improved
Example: “Early in my career, I struggled with delegating tasks because I wanted to ensure everything was perfect. This led to me becoming overwhelmed during a major project. I realised I needed to trust my team more and focus on clear communication of expectations rather than doing everything myself. I’ve since developed a delegation framework that’s improved both my productivity and my team’s development.”
When You’re a Recent Graduate with Limited Experience
Don’t panic if you lack extensive professional experience. Draw examples from:
- University projects and group work
- Part-time jobs or internships
- Volunteer activities
- Sports teams or societies
- Personal projects or entrepreneurial ventures
The competencies are transferable, even if the context is different. A retail job can demonstrate customer service, problem-solving, and working under pressure just as effectively as a corporate role.
