If your target department uses a Multiple Mini Interview (MMI), the format can feel very different from a traditional panel interview. You move through short stations, reset between them, and have limited time to organize each response. That rewards a different kind of preparation.
What an MMI Is
The MMI format was originally developed at McMaster University for medical school admissions. Some fire departments also use an MMI structure to assess candidates across several short, independent stations rather than one continuous interview.
Instead of one interview with one panel, you move through a series of short, independent stations. Each station poses a different question or scenario, you get a short window to gather your thoughts, and a short window to respond, then you move to the next station and start over with a completely different evaluator and a completely different topic.
As one real example, Edmonton Fire Rescue Services runs its MMI across seven stations, with two minutes to prepare and five minutes to respond at each one. Other departments run a similar structure with their own specific timing and station count, so always confirm the exact format with your target department rather than assuming every one runs it identically.
Why It Catches People Off Guard
A traditional interview lets you build momentum: a strong first answer buys you goodwill for the rest of the conversation. An MMI resets that every few minutes. A weak answer at station two doesn't follow you to station three, but neither does a strong one. Every station is judged almost entirely on its own.
That means the skill being tested isn't "can you tell a good story once." It's "can you perform consistently, station after station, on questions you can't fully prepare for in advance because you don't know what's coming next."
What Helps
You can't memorize your way through an MMI, and departments design it that way on purpose. What helps instead:
- Genuine self-knowledge. Panels can tell the difference between a rehearsed answer and someone who knows their own strongest examples cold.
- A repeatable structure for answering under pressure, not a script, a structure you can apply to a question you've never heard before.
- Practice with the actual format, short prep time, short response time, immediate reset, not a mock version of a traditional interview.
Where Coaching Helps
One to one coaching builds a repeatable structure and enough realistic practice that the format itself stops being the thing you are fighting. It does not hand you answers.
