Interview formats vary by department. Calgary currently uses an in person Behavioural Descriptive Interview and requires answers in the STAR format. Edmonton currently publishes a Multiple Mini Interview process with seven stations. Candidates should prepare for the format used by their target department.
What Panels Need to Hear
A strong answer gives the panel enough information to assess your behaviour and judgement.
Your example should make four things clear:
- What was happening
- What responsibility you had
- What you personally did
- What happened because of your actions
The panel should not have to guess which part of the story belongs to you.
Use STAR Properly
The City of Calgary describes STAR as Situation, Task, Actions, and Result.
Situation
Give only the context the panel needs. Who was involved, what was happening, and why did it matter?
Task
State your responsibility. Make it clear what you were expected to accomplish or resolve.
Actions
Spend most of your answer here. Explain what you did, why you chose that approach, how you communicated, and how you adjusted when the situation changed.
Result
State the outcome. Include what changed, what you learned, or what you would carry forward.
STAR is a structure, not a script. If every answer sounds memorized, the format has stopped helping you.
Build a Story Bank
Do not start preparation by trying to predict every possible interview question.
Start by identifying strong examples from your own experience. A useful story bank often includes situations involving:
- Teamwork
- Conflict
- Leadership
- Accountability
- A mistake or setback
- Customer or public service
- Safety and judgement
One example may support more than one competency, but do not force the same story into every answer.
Choose Better Examples
The best example is not always the most dramatic event in your career.
Choose an example where your individual role is clear and where you can explain your decisions. A simple workplace conflict that you handled well may be more useful than a complex emergency where your personal contribution is difficult to separate from the team.
Good examples are specific, defensible, and easy to explain.
Practise Without Memorizing
Use the same process for every practice round.
- Read or hear the question once.
- Take a short moment to identify what is being assessed.
- Select the story before you begin speaking.
- Answer out loud and review what was unclear.
Written preparation helps organize ideas. Spoken practice shows whether those ideas work as an answer.
Record some practice answers. Listen for long introductions, vague actions, repeated phrases, and results that never arrive.
Common Interview Problems
Too Much Context
Candidates often spend most of the answer describing the situation. The panel needs enough context to follow the story, not every detail that happened before it.
Speaking for the Team
“We” can hide your individual contribution. Use it when the team acted together, but make your own decisions and actions clear.
Generic Claims
Saying you are accountable, resilient, or a strong communicator does not demonstrate those qualities. Use an example that lets the panel assess them.
Memorized Wording
A polished script can fail when the question is worded differently than expected. Practise the structure and your stories instead of memorizing paragraphs.
No Result
Finish the story. Explain what happened, what changed, and what you learned.
Calgary Interviews
The Calgary Fire Department currently describes its interview as an in person Behavioural Descriptive Interview. The City states that answers need to be presented in STAR format.
Candidates preparing for Calgary should be comfortable selecting a relevant example quickly and explaining their individual actions clearly.

Edmonton MMIs
The City of Edmonton currently publishes a Multiple Mini Interview format with seven stations. At each station, candidates receive one question, two minutes to gather their thoughts, and five minutes to respond.
The City also states that the MMI currently accounts for 50 percent of a candidate’s overall score. Edmonton has announced that it is updating the recruitment process for the 2027 intake, so candidates must confirm the final process before relying on the current format.

A Two Week Practice Plan
Days 1 to 3
Research the department and review the published process. Build a list of competencies and themes that appear repeatedly in the department’s own material.
Days 4 to 6
Build your story bank. Write short notes for the situation, task, actions, result, and lesson from each example.
Days 7 to 10
Practise answering out loud. Rotate question types so you learn to select the right story instead of memorizing a fixed sequence.
Days 11 to 13
Run realistic mock interviews. Use time limits, unfamiliar questions, and follow up questions.
Day 14
Review your weakest areas and stop adding new material. Go into the interview with a clear set of stories and a repeatable answer process.
When Coaching Becomes Useful
Everything above is enough to prepare on your own, and many candidates do exactly that. Coaching earns its place when you want a second opinion on whether your answers land, from someone who has sat on the other side of the process.
It is usually worth it when you have an interview date, when your examples feel strong to you but you cannot tell whether a panel would agree, or when you have interviewed before and were not selected without being told why.
Need More Than Self Study?
If you want somebody to watch how you answer, challenge your evidence and help you prepare for the pressure of the real interview, Northline has several interview preparation options.
