If your target department uses a Multiple Mini Interview (MMI), expect a different format from a traditional panel interview. You move through short stations, reset between them, and have limited time to organize each response, so you prepare for it differently.

What an MMI is

McMaster University developed the MMI format for medical school admissions. Some fire departments also use an MMI structure to assess candidates across several short, independent stations in place of one continuous interview.

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 different evaluator and a different topic.

Edmonton Fire Rescue Services, for example, 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 timing and station count, so confirm the format with your target department.

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 every few minutes, and each station is judged almost entirely on its own, whether your last answer was weak or strong.

The format tests whether you can perform consistently, station after station, on questions you meet for the first time in the room.

How to prepare for an MMI

An MMI rewards thinking on your feet, and departments design it that way on purpose. Three things help:

  • Knowing your own strongest examples cold. Panels can tell that apart from a rehearsed answer.
  • A repeatable structure for answering under pressure, one you can apply to a question you are hearing for the first time.
  • Practise in the actual format: short prep time, short response time and an immediate reset.

Where coaching helps

One to one coaching builds a repeatable structure and gives you enough realistic practice that the format stops getting in your way. The answers stay yours. Start with the Firefighter Interview Preparation guide, or review the Firefighter Interview Intensive if you want direct feedback.
