MMI Practice: How to Prepare for Multiple Mini Interviews
A multiple mini interview (MMI) is a circuit of short, timed stations used by many medical, dental and other health schools. Each station tests one thing, such as ethical reasoning, empathy in a role-play or your motivation. Prepare by practising every station type out loud, against the clock, with a simple structure you can reuse.
What is an MMI, and how do you prepare for it?
The MMI was developed at McMaster University in Canada to measure qualities a single panel interview misses, and it is now used by schools in Canada, the UK, Australia, the US and elsewhere. Formats vary: check how many stations your school runs, how long you get to read each prompt and how long each station lasts, and practise to that timing.
The six MMI station types
Most circuits mix these. Practise at least one of each.
| Station | Example prompt | What it assesses | How to approach it |
|---|---|---|---|
| Ethical scenario | A patient asks you not to tell their family about a diagnosis. | Whether you see every party's interests, weigh them and reach a reasoned, safe decision | Name the dilemma, the people affected and the principles in tension, then the options and the one you would choose and why. |
| Role-play | Tell a friend you cannot cover their shift again; an actor plays the friend. | Empathy, listening and how you handle emotion | Acknowledge the feeling first, ask before you explain, and agree a next step together. |
| Healthcare or policy issue | Should doctors be allowed to strike? | Whether you can reason through a contested question and stay balanced | Give both sides fairly, say what the answer depends on, then take a position you can defend. |
| Teamwork task | Guide a partner to draw a shape you can see and they cannot. | Clear instructions, checking understanding and staying calm | Agree how you will work, give one instruction at a time and check before moving on. |
| Personal and motivation | Why medicine, and why not nursing or research? | A genuine, specific motivation and insight into the role | One real experience, what it showed you about the work, and why this role fits it. |
| Data or picture | Interpret a chart of waiting times, or describe what you see in an image. | Observation, structured thinking and honesty about what the data does not show | Describe before you interpret, say what you would want to know next, and avoid over-claiming. |
A structure that works at any station
Use the reading time to plan, not to script.
- Name the issue. In one sentence, say what the station is really about: a conflict between autonomy and safety, a friend who is upset, a question with two reasonable sides.
- Find the people and the facts. Who is affected, what you know and what you would need to find out before acting.
- Weigh the options. Two or three, fairly, including the one you will not choose.
- Decide and justify. Say what you would do and why, and what would change your mind.
- Close. A next step, a safety net, or what you learned. Then stop; silence is better than repetition.
In role-play stations, swap the order: listen and acknowledge first, then explain. Assessors watch how you respond to the actor, not only what you say.
How to practise MMI out loud
Timed, spoken and reviewed: reading model answers is not practice.
Set a timer for the reading period and the station, read a prompt, and speak for the full time. Practise the station types you find hardest twice as often. After each one, check the structure above: did you name the issue, weigh options and reach a decision?
An AI interviewer adds the part a timer cannot: a challenge to what you just said. In the VirtualInterview.ai admissions interview, enter medicine, your school and who is interviewing you; the interviewer asks about your motivation, the programme and your reasoning, and presses on claims you have not supported. The report scores Subject knowledge (30%), Reasoning (30%), Clarity of explanation (20%) and Motivation and fit (20%). For a specific station, such as an ethical scenario, describe it in the practice box and answer it out loud.
It does not replace a timed circuit with real actors, and it does not predict an offer. If you are preparing for residency rather than medical school, see the residency interview practice page and the residency interview questions.
Frequently asked questions
- What is an MMI interview?
- A multiple mini interview is a circuit of short, timed stations. At each one you read a prompt, then speak with an assessor or an actor about a scenario, an ethical dilemma, a policy question, a task or your motivation. Each station is scored separately, so a weak one does not decide the day.
- How do I practise for MMI stations?
- Out loud and against the clock. Read a prompt, take the reading time the school gives, then answer for the full station time without stopping. Practise every station type, record yourself or use a partner, and review structure: did you name the issue, weigh the options and reach a reasoned conclusion?
- How long is each MMI station?
- It varies by school. Most give a short reading period followed by several minutes at the station, and a circuit runs through several stations. Check the format your school publishes and practise to that timing.
- Is there a right answer in an MMI ethical station?
- Rarely a single one. Assessors score the reasoning: whether you saw the people affected and the principles involved, considered the options fairly and reached a decision you can justify. A confident answer that ignores one side scores lower than a balanced one.
- Can I practise MMI with AI?
- Yes, for the spoken stations. Choose the admissions interview, enter medicine and your school, and the AI interviewer asks motivation, ethics and reasoning questions and challenges your claims. For a specific station, describe it in the practice box. The free plan includes 2 interviews a month with no card, in 50+ languages.
