Competency based interview questions how they work in Ireland, with STAR examples

What are competency-based interview questions?

Competency-based interview questions ask you to prove a skill with a real example from your past: "Tell me about a time you...", "Give an example of when you...". The panel scores the example, not your opinion of yourself. Answer each one with a single, specific story told in order: the situation, your task, what you did, and the result.

In Ireland you meet them in two places. The public service uses them in formal, scored interviews run through publicjobs.ie and other public bodies. And many private employers, from banks to multinationals to hospitals, use the same style because it is fair and easy to compare. The JobsIreland.ie tips say these interviews focus on the skills the job needs, usually listed in the job description, and advise basing your examples on the indicators given under each competency.

Competency or capability: the Irish public service set-up

This is the part most guides miss. The publicjobs.ie interview advice says: "In 2024, a new Civil Service Capability Framework was designed." It also says that some roles may use the Civil Service Competency Model and others the new Capability Framework, and that candidates are told in advance which model, or another method, will be used.

The Capability Framework page links the framework for six Civil Service grades: Clerical Officer, Executive Officer, Administrative Officer, Higher Executive Officer, Assistant Principal Officer and Principal Officer. Whichever model your competition uses, the candidate information booklet tells you what the panel will look for. Read it before anything else.

STAR, the publicjobs.ie way

publicjobs.ie suggests the STAR method for competency answers. The way it describes each step is worth reading closely, because the last step asks for more than most people give:

1. Situation. Brief context: where you were, your role, the background. Two sentences at most.
2. Task. The challenge and what you were aiming for.
3. Action. The specific steps you took and the skills you used. This is the longest part and the part that scores.
4. Result. The outcome, how you measured success, what you learned, and how it links to the role you are applying for.

That last point is the Irish twist on a familiar method. Ending with "and that's the kind of planning I'd bring to this role" connects your story to their job, so the panel does not have to do the work.

A simple balance to aim for: a quick Situation and Task, a full Action, and a Result with one clear outcome and one lesson. If you want a draft to edit, the free STAR method answer generator turns your notes into the four parts.

The capability-based interview

publicjobs.ie explains in its guide to the new Capability Framework that this approach "aims to gather insight into the whole person". Questions fall under three headings:

• Experience, Examples and Behaviours. The familiar "tell me about a time" questions. STAR still works here.
• Skills, Strengths and Knowledge. What you are good at and what you know. "What would you say is your greatest strength, and where have you used it?"
• Values, Motivation and Interests. Why this work, why the public service, what keeps you going. "What draws you to a role serving the public?"

The same guide advises reviewing the framework and the candidate information booklet, reflecting on your career and education, and linking your skills, strengths, values and motivations to the job description. If you have little direct experience, it says to draw on transferable skills.

Example (illustration), a motivation question: "I spent four years in retail banking, and the part I liked was helping people sort out a problem they had been worried about for weeks. Working in a public office that deals with people at a stressful time is the same thing on a bigger scale, and I'd like my work to have that purpose."

STAR interview questions with Irish examples

These behavioural interview questions (behavioral, in US spelling) are typical of Irish public and private sector panels. The answers are illustrations to show the shape. Use your own stories.

1. "Tell me about a time you explained a complicated rule to someone who was frustrated."

Example (illustration). Situation: I worked on the front desk of a county council motor tax office. Task: A customer was angry that his application had been returned and did not understand why. Action: I let him finish, then went through the form with him line by line, showed him the missing document on the checklist, and wrote down exactly what to bring back. I also told him the quieter times to come in. Result: He came back two days later with the right papers and thanked me. I learned to show people the rule on paper rather than just repeat it, which I would use in a role dealing with the public every day.

2. "Give an example of when you spotted a mistake others had missed."

Example (illustration). Situation: I was an accounts assistant in a logistics company in Dublin. Task: At month end I noticed one supplier had been paid twice for the same invoice. Action: I traced it to a duplicate entry after a system upgrade, flagged it to my manager, contacted the supplier for a credit note, and suggested a duplicate check on the payment run. Result: The money was recovered the next month and the check was added to our process. It taught me to look for the cause, not just fix the one error.

3. "Describe a time you managed a heavy workload when the team was short."

Example (illustration). Situation: Two of the five nurses on my ward in a regional hospital were out sick during a busy week. Task: I had to make sure our patients' care plans and handovers stayed safe and on time. Action: I listed the tasks by urgency with the clinical nurse manager, asked a healthcare assistant to take the non-clinical jobs, and kept short written handovers so nothing was lost between shifts. Result: Every handover was completed and nothing was missed. I learned to ask for help early, before things slip.

4. "Tell me about a time you used technology to improve how something was done."

Example (illustration). Situation: I volunteered with a local GAA club where the membership list was kept on paper. Task: Registrations each spring took weeks and fees were often missed. Action: I set up an online form, moved the records into a spreadsheet, and showed the committee how to use it. Result: Registration that season took a fraction of the usual time and the treasurer could see who had paid. For this role, it shows I am comfortable learning and teaching new systems.

5. "Give an example of feedback you received and what you did with it."

Example (illustration). Situation: In my first year as a graduate analyst in a Cork tech company, my manager said my reports were accurate but too long. Task: I needed to make them useful for busy managers. Action: I asked to see a report she liked, rebuilt mine with a three-line summary at the top, and checked with her after two weeks. Result: She started forwarding my summaries to the director. I now ask for feedback early on any new piece of work.

6. "Tell me about a time you worked with people from another team to deliver something."

Example (illustration). Situation: I was a customer service lead for a utility company when we moved to a new billing system. Task: Customers were getting confusing bills, and our team was taking the calls but IT owned the fix. Action: I logged the five most common problems with examples, met the IT lead weekly, and wrote short scripts so my team could explain the issue while it was fixed. Result: The repeat calls on those issues dropped steadily over the next month. I learned that a clear list of examples gets a faster fix than a general complaint.

Build your example bank

publicjobs.ie suggests preparing about 10 achievements from different areas of your life, such as education, work and interests, and picking about five qualities most relevant to the job. Here is a simple way to do it:

1. List the skills. Take each skill or competency from the job description or booklet.
2. Find two examples per skill. One from work, one from somewhere else if you can: college, a club, volunteering, caring. Panels may ask for a second example.
3. Write each in STAR bullets. Four short lines, not a script.
4. Add the lesson. One sentence on what you learned and how it fits this role.
5. Say them out loud. publicjobs.ie suggests practising with a friend, family member or colleague, and recording yourself.

Your answers to the opening questions come from the same bank. For the very first one, see our guide to tell me about yourself.

Where marks are lost

• "We" all the way through. The panel scores what you did. Say "I".
• A hypothetical answer. "I would..." is not an example. Give one that happened.
• A long Situation. If you are still setting the scene after a minute, the Action gets squeezed.
• No ending. Stories that trail off lose the Result marks. Finish with the outcome and the lesson.
• The same example for everything. Use a different story for each skill if you can.
• Ignoring the booklet. If the booklet names the areas the panel will assess, your examples should match them.

Practise competency questions out loud

Reading your STAR bullets is not the same as telling the story to a panel. Practise each one aloud until it fits in about two minutes and ends cleanly. Then mix the questions up so you get used to picking the right example quickly.

For a private sector video interview on your laptop, the ClapAssist AI interview assistant can show a short STAR prompt from your own CV when the question comes, in English or many other languages. Public service and other employers may not allow AI help in interviews or assessments: follow your booklet and invitation, and read is ClapAssist safe? before you decide.
