Is a Mock Interview Worth It?

You have made it through the online tests, the skills assessment, and however many months of waiting. Now you have an interview date. The question is whether to book a mock session, or to keep practising on your own and save the money.

Mock interviews are not free, and not every version of them is equally useful. Here is an honest look at when the investment pays off and when it does not.

What makes a publicjobs interview different from a standard job interview

If you have only ever sat a private-sector panel, the publicjobs interview is going to feel quite different. Every candidate at a given grade level is asked the same questions, in the same order, by a board of typically three assessors. There is a strict schedule, and if your answer runs long the panel will move on whether you have finished or not.

The questions are structured around either the Civil Service Competency Model or the newer Capability Framework, which has been used across large volume campaigns since February 2024. Your call-up letter will tell you which one applies to your competition. Either way, the format is competency-style: tell me about a time you did X, walk me through how you approached Y.

You will be expected to answer in a structured way, with your own individual contribution front and centre. “We decided” and “the team achieved” are the two phrases most likely to cost you marks. The assessors are scoring your evidence, not your team’s.

For a fuller picture of what each stage involves, the guide to preparing for your publicjobs competency interview covers the format in detail.

The real reason candidates underperform

It is rarely a lack of examples. Most people sitting an EO or HEO interview have genuinely done the things the competencies ask about. The problem is in the telling.

The most common patterns I have seen, and experienced myself, are these:

Too much context, not enough action. The situation and task sections of a STAR answer should set the scene briefly. The action section is where the marks are. Candidates who spend three-quarters of their answer explaining the background and only a sentence on what they personally did tend to score poorly, even if the underlying example is strong.

Scripted delivery. Over-rehearsed answers often sound flat or robotic. A panel that is taking notes and working to a clock picks up on it quickly. The goal is to be prepared, not to recite.

Losing the thread under pressure. Three assessors, a formal room or a video screen, someone taking notes while you speak. It is a pressured environment, and going blank mid-answer or drifting off-topic is extremely common when people have only practised in their heads.

Reusing examples without adapting them. You can reuse examples across subdimensions in the Capability Framework, but the framing needs to shift each time to show a different angle of your contribution.

What does a good mock interview actually give you?

Done well, a mock gives you three specific things a solo prep session cannot.

Realistic pressure. Talking to another person who is asking the questions and noting your answers creates a different mental load than rehearsing in front of a mirror. The discomfort of being observed is exactly what you need to experience before the real board.

Honest, specific feedback. This is the part most candidates underestimate. Reading back over your notes after a solo session tells you very little about how you actually came across. A good mock will flag whether you sounded confident or hesitant, whether your action section was long enough, whether you kept saying “we” when you meant “I”. That kind of targeted feedback is hard to replicate any other way.

A calibrated sense of timing. You will not know how long two minutes feels mid-answer until you have tried it under observation. The official guidance from publicjobs suggests preparing roughly ten examples across different areas of your life, and coaching sources generally recommend that each answer runs somewhere in the two to three minute range, with the majority of that time on action. Whether that pacing feels natural to you is something you can only find out by doing it.

When a mock is NOT worth it

There are situations where paying for a mock session before you are ready is a poor use of money.

If you do not yet have a solid bank of examples mapped to the competencies or capabilities being assessed, a mock will expose that gap but not fix it. The prep work has to come first. The full picture of how publicjobs competency-based interviews are structured is worth reading before you consider a mock, so you know what you are being assessed against.

If the mock you are looking at is generic, meaning it is not tailored to the publicjobs format, the Capability Framework, or the specific grade you are competing at, you are likely practising for a different interview than the one you will sit. A lot of what is available online is built for UK public sector panels, which use a different model and different weighting.

And if the feedback you will receive is limited to vague encouragement, it is hard to justify the cost.

What PublicServicePathway includes for this

The interview prep on PublicServicePathway is built for the publicjobs process: framework guides for your grade, a work experience bible and role-specific mock practice. Interview Prep is €19 a month; Premium is €39 a month when you also need the assessment bank.

Written coaching on your own examples marks them against the specific signals that matter to Irish Civil Service boards: individual contribution, structure, timing, and whether your evidence is concrete enough to score.

The guides and question bank do most of the rest of the job: work through them, say your answers out loud against the framework for your grade, and you are rehearsing under something close to board conditions. If you want a second, human opinion before the day, that is what a coach is for, and this article is an honest attempt to help you decide whether you need one.

FAQ

Can I get feedback on a publicjobs interview after it takes place?

Yes. Publicjobs offers feedback on request for up to six months after the interview stage closes. Many candidates do not know this. It is worth requesting even if you pass, because it tells you which areas scored lower and where to focus if you sit another competition. Check the publicjobs FAQ page for how to apply.

Is the STAR method required, or can I use a different structure?

Publicjobs does not mandate a specific framework, but structured answers that clearly identify the situation, your action, and the result tend to score better because they are easier for assessors to note and compare. The specific label matters less than the discipline of separating what you did from what the team did, and being concrete about the outcome.

What competencies or capabilities are assessed at EO level?

For the Capability Framework (in use for large volume campaigns since February 2024), the EO profile is organised under four dimensions: Building Future Readiness, Evidence Informed Delivery, Leading and Empowering, and Communicating and Collaborating. Six capabilities sit under them at EO level, including Delivering Excellence, Managing Information, Problems and Decisions, Leading, Supporting & Developing and Leading with Specialist Insight. For older competitions still using the Civil Service Competency Model, the assessed areas typically include Delivery of Results, Analysis and Decision Making, Interpersonal Skills, and others. Your call-up letter and the publicjobs website will confirm which applies to your competition.

Do I need separate examples for every competency, or can I reuse them?

You can reuse the same example across different subdimensions within the Capability Framework, provided the framing shifts to highlight a different aspect of your contribution each time. Having around ten solid examples from different contexts gives you enough material to adapt without repetition becoming obvious. Publicjobs advises preparing a range of examples from various areas of your working and personal life.
