Getting shortlisted for a government job interview is a real milestone — most applicants never get this far. But the interview itself catches a lot of people off guard, because the public service overwhelmingly uses a specific interview style, competency-based interviewing, which rewards a very particular kind of answer. Understanding the format before you walk in makes a bigger difference than most applicants expect.
What “Competency-Based” Actually Means
Rather than asking hypothetical questions like “how would you handle a difficult colleague,” a competency-based interview asks you to describe a real situation you’ve actually been in: “tell me about a time you handled a difficult colleague.” The panel isn’t interested in your theory of good conduct — they want evidence, drawn from your actual experience, that you’ve demonstrated the specific competency the post requires. This is why simply knowing the “right answer” in the abstract isn’t enough; you need a genuine, specific example ready to go.
The Panel and Format
Government interviews are typically conducted by a panel rather than a single interviewer — often three to five people, which may include the hiring manager, an HR representative, and sometimes a union observer or a representative from another relevant unit. Panels usually work from a standardised set of questions applied consistently to every shortlisted candidate, which is part of how the public service aims to keep the process fair and defensible. Don’t be surprised if the questions feel formal or scripted; that’s by design, not a sign of disinterest.
Structuring Your Answers: The STAR Method
The most reliable way to answer competency-based questions is the STAR structure:
- Situation: briefly set the context — where, when, what was going on
- Task: what specifically were you responsible for or trying to achieve
- Action: what did you actually do — this is the part to spend the most time on
- Result: what happened, ideally with a concrete outcome or what you learned
Panels are trained to listen for this structure, and answers that ramble without a clear action or result tend to score poorly even if the underlying experience was strong. It’s worth preparing two or three STAR examples in advance that you can adapt to different questions, rather than trying to improvise a fresh story for every single question on the spot.
Common Competencies Assessed
While the exact competencies vary by post and level, government interviews frequently probe:
- Problem solving and decision making under pressure or with limited information
- Working within policy, regulation, or a chain of approval (particularly relevant given how much of public service work involves compliance)
- Communication and stakeholder engagement, especially for public-facing roles
- Planning and organising, particularly for roles managing budgets, projects, or teams
- Handling conflict or a difficult interpersonal situation professionally
Senior posts often add competencies around strategic thinking, financial management, and people leadership, in line with the added responsibility at that level.
Practical Interview Preparation
Beyond preparing STAR examples, it’s worth reviewing the job advertisement and the department’s core mandate closely — panels frequently ask why you want to work for that specific department, and a generic answer stands out for the wrong reasons. If your application included a Z83 form, CV, or cover letter, revisit what you wrote, since panels sometimes ask direct follow-up questions based on your own submitted documents.
After the Interview
Being interviewed doesn’t guarantee an offer — most government posts move through security vetting and reference checks before a final decision is made, particularly for posts requiring access to sensitive information or facilities. Our guide to security clearance and vetting explains what typically happens at this next stage and how long it can take.
Frequently Asked Questions
Is it acceptable to ask the panel questions at the end of the interview?
Yes, and it’s generally viewed positively. Asking about the team structure, key priorities for the role, or next steps in the process shows genuine engagement, as long as the questions are specific rather than generic.
What should I do if I don’t have direct experience with a competency the panel asks about?
Draw on the closest relevant experience you do have — from a different job, a volunteer role, or academic project — and be honest about the context rather than stretching an unrelated story to fit. Panels generally respond better to an honest, well-structured answer from adjacent experience than an overreaching one.
How soon after the interview will I hear back?
Timelines vary considerably depending on the department, the number of candidates interviewed, and whether vetting is required. Our guide on government hiring timelines gives a realistic sense of what to expect at each stage.
