Policy officer interviews can test how you turn incomplete or conflicting information into advice someone can use. Prepare to explain how you checked a source, weighed an option and distinguished your recommendation from a decision you did not have authority to make.
The two answers and briefing exercise below are fictional teaching examples. They are original practice material, not official questions or successful client responses. Use them to identify the detail your own examples need, then prepare against the duties and capabilities of the advertised role.
Conflicting evidence in a briefing
Original practice question: Tell us about a time you encountered conflicting evidence while preparing advice. How did you decide what to include?
Fictional spoken example.
I was supporting a review of a community program and preparing a short briefing on participation. An internal summary suggested that participation had increased, while a partner organisation’s report described a decline. My responsibility was to check the evidence and draft advice for my manager, rather than decide the program’s future.
I went back to the definitions and reporting periods before comparing the totals. The internal summary counted attendances, including repeat visits, while the partner report counted individual participants over a different period. I set out those differences in a working note and checked my interpretation with the people responsible for each dataset.
I then identified which figures could be compared on the same basis and which could not. Where information was missing, I recorded the gap instead of treating it as zero. In the draft briefing, I separated what the data showed from possible explanations. I also included the partner’s concerns as stakeholder evidence, while making clear that they were not a directly comparable measure of participation.
I recommended obtaining a consistent participant measure before drawing a conclusion about the overall trend. My manager used the revised briefing to request that follow-up information. The immediate result was advice that did not present two different measures as a proven contradiction. It reinforced for me that a clear limitation is more useful than a confident conclusion the evidence cannot support.
Why this works: The applicant checks definitions, reporting periods and missing data, then changes the advice accordingly. The example shows analytical judgement without inventing a major policy outcome.
Adapt it: Identify the actual sources you used and the checks you made. Explain whether you gathered evidence, analysed it, drafted recommendations or approved the final advice. Those are different contributions.
Stakeholders disagree about an option
Original practice question: Describe a time stakeholders had different views on a proposed approach. How did you help develop useful advice?
Fictional spoken example.
I helped prepare options for changing an application form used by a small grants program. The delivery team wanted fewer questions to make the form easier to complete. The reporting team was concerned that removing fields would leave them without information they needed later. I was asked to document the issues and draft an options paper for the program manager.
I spoke with each team about how they used the disputed fields. That showed that some information was needed to assess an application, while other information was used only after a grant had been approved. I checked the program’s existing requirements with the manager and recorded the points that still needed specialist advice, rather than making a compliance judgement myself.
I drafted three options: retain the current form, remove the disputed fields, or collect the later-stage information after approval. For each, I described the effect on applicants, the work required from staff and the information that would be available at each stage. I circulated the factual summary to both teams so they could correct misunderstandings before the manager considered the recommendation.
The manager selected the staged approach, subject to the outstanding checks. I recorded the decision and the follow-up responsibilities in the paper. Both teams could see how their concerns had been represented, even though neither received its original proposal unchanged. My role was to make the trade-offs clear and support a decision, rather than suggest that consultation meant everyone had to agree.
Why this works: The applicant investigates the reason behind each position, tests options and preserves unresolved checks. The decision is attributed to the manager.
Adapt it: Describe a genuine disagreement and the evidence that changed your understanding. Be ready to explain what you would have done if a stakeholder challenged the accuracy of your summary.
A short briefing exercise to practise
An assessment may involve more than an interview. The Australian Public Service Commission’s assessment guidance describes possible methods including work samples and presentations. Follow the invitation for your particular role; do not assume a written exercise will always be included.
Fictional practice task: Write a short recommendation to a manager deciding whether to extend a pilot. Use only these supplied facts: the pilot has run for eight weeks; staff feedback is positive; the cost report is incomplete; participation data covers only four weeks; and a decision is requested by Friday. No further facts are available for this exercise.
Illustrative response:
I recommend seeking the missing cost and participation information before making a decision on a full extension. Positive staff feedback is useful, but it does not establish the pilot’s overall cost or participation across the eight weeks.
Before Friday, we should confirm when the complete reports can be provided and whether the decision date can move. If a decision is required on Friday, the briefing should set out the evidence gaps and the implications of deciding with incomplete information. Any option to continue temporarily would also need its cost and approval requirements checked; the supplied facts do not establish that this is available.
The immediate next step is to obtain a confirmed reporting timetable and clarify the decision deadline with the manager. This would support a recommendation with its limitations visible.
What to notice: The response identifies a recommendation, its evidence and the next action. It does not invent a budget, claim that the pilot succeeded or assume authority to extend it. Another defensible response may reach a different recommendation, provided it explains the assumptions and stays within the facts.
Build an evidence bank you can explain
Choose examples that show research, judgement, clear writing and working with others. An example from a university project, community organisation or private-sector role can be useful if it demonstrates the advertised requirement and you describe your contribution accurately. Do not relabel routine work as a policy decision to make it sound more senior.
For NSW roles, use the stated capabilities and levels in the role description alongside the NSW Capability Application Tool. For APS roles, follow the agency’s candidate information and classification expectations. The title “policy officer” alone does not establish the scope of responsibility.
Practise explaining why you trusted a source, which alternative you considered and what you would check next. Our guide to the Action section of a STAR answer helps make those decisions visible. For roles combining advice and delivery, see our project officer interview examples.
