APS interviews are designed to assess capability through behavioural evidence. Most candidates already have strong experience, yet lose marks because their responses reduce clarity rather than demonstrate it. The difference between a good interview and a successful one is often not experience, but how clearly that experience is expressed under pressure.
This guide outlines the most common reasons candidates underperform in APS interviews and provides practical strategies to improve clarity, structure, and interview performance.
1. Speaking at task level rather than capability level
One of the most common issues is describing what was done rather than demonstrating how capability was applied. Candidates often stay focused on tasks, processes, or responsibilities without showing judgement, decision making, or influence.
This typically sounds like a list of activities rather than evidence of capability.
A more effective response shows how decisions were made, how complexity was managed, and what changed as a result of your actions.
How to improve this
Before answering, ask yourself what capability the question is really targeting. Then structure your response so that your actions and decisions are the focus rather than the workflow. Emphasise why you made decisions, not just what you did.
2. Overly long context setting
Many candidates spend too long describing background, organisational structure, or project history before getting to their contribution. While context is important, excessive setup reduces the time available to demonstrate capability.
Panels are not assessing the situation itself, they are assessing your behaviour within it.
How to improve this
Keep context short and functional. One to three sentences is usually enough. Focus on what was relevant to your role, the problem you were addressing, and the constraints that shaped your decisions. Move into action quickly.
3. Weak or vague outcomes
A frequent gap in APS interview responses is unclear or generic results. Statements such as “it went well” or “the project was successful” do not provide evidence of impact.
Panels need to understand what changed because of your actions.
How to improve this
Define outcomes in concrete terms where possible. This might include improvements in timeframes, quality, stakeholder satisfaction, risk reduction, or decision making impact. If measurable data is not available, describe observable changes in behaviour, process, or decision quality.
4. Unclear individual contribution
Candidates often describe team activity without making their own role visible. While collaboration is important in APS environments, panels still need to understand your specific contribution.
When everything is described as “we”, your capability becomes difficult to assess.
How to improve this
Use a balanced approach where you clearly state your role within the broader team effort. Show where you led, where you influenced, and where you contributed directly. Make your decision points visible and distinguish your actions from group activity.
5. Lack of structure under pressure
Even experienced candidates lose structure in interviews. Answers become conversational, repetitive, or fragmented, which makes it harder for panels to follow the logic of the response.
This is often a confidence issue rather than a capability issue.
How to improve this
Use a consistent structure such as STAR to anchor your response. Keep it simple and predictable under pressure. If you lose your place, pause briefly and return to the structure rather than continuing without direction.
Recognising these mistakes in your own interviews?
Most APS candidates already have strong examples. The challenge is communicating them clearly under pressure.
6. Not showing decision making
APS interviews place strong emphasis on judgement. Many candidates describe what happened but not how decisions were made or why certain options were chosen.
This leaves a gap in capability assessment.
How to improve this
Explicitly describe your thinking process. Explain what options were considered, what constraints existed, and why a particular course of action was taken. This is especially important at APS6, EL1, and EL2 levels where judgement is a key assessment criterion.
7. Over-reliance on prepared scripts
Some candidates prepare answers word for word and attempt to reproduce them in the interview. This often results in responses that sound rehearsed, rigid, or disconnected from the question being asked.
Panels are not assessing memory. They are assessing adaptability and judgement.
How to improve this
Prepare structured examples rather than scripts. Know your examples well enough to adapt them to different questions. Practise speaking them in different ways so you can adjust emphasis depending on the question.
8. Ignoring the level being applied for
APS level expectations matter
An APS6 example focused on personal delivery may not demonstrate sufficient influence or strategic judgement for an EL1 or EL2 role. Panels assess both capability and the level at which capability is demonstrated.
A common issue is using examples that demonstrate capability at a lower level than the role being applied for. For example, describing delivery work for an EL1 role without demonstrating influence or leadership.
This results in technically strong answers that do not meet capability expectations.
How to improve this
Use the APS Integrated Leadership System as a reference point. Before the interview, review how capability expectations change across levels. Reframe examples to emphasise autonomy, influence, complexity, or strategic judgement depending on the role.
9. Weak communication under pressure
Many candidates perform well in preparation but struggle to maintain clarity under interview conditions. This often leads to rushed answers, filler words, or loss of structure.
This reduces the panel’s ability to assess capability clearly.
How to improve this
Practise speaking your examples out loud, not just thinking or writing them. Simulate interview conditions where possible. Build comfort with pauses, silence, and structured thinking. Clarity is more important than speed.
10. Treating every answer as unique
Some candidates attempt to create a completely new example for each question. This increases cognitive load and reduces performance under pressure.
Strong candidates reuse and adapt a small number of well-understood examples.
How to improve this
Build a small set of strong, flexible examples that can be adapted across multiple questions. Focus on depth of understanding rather than breadth of preparation.
Bringing it together
Most APS interview challenges are not caused by lack of experience. They are caused by unclear expression of that experience under structured questioning.
Improving performance is less about learning new content and more about refining how you communicate:
- clarity over complexity
- structure over spontaneity
- judgement over description
- impact over activity
Practical Exercise
Take one of your recent interview answers and review it against the ten mistakes in this guide.
- Where do you spend too much time?
- Where is your judgement unclear?
- Where is your individual contribution difficult to identify?
- Where could your impact be demonstrated more clearly?
The strongest improvements often come from refining existing examples rather than creating new ones.
Ready to strengthen your APS interview performance?
Many interview challenges come down to structure, clarity, and how well your examples demonstrate judgement and impact. The next step is deciding whether you need a deeper understanding of APS interviews, support refining your interview examples, or help identifying what is holding you back.
