The multiple mini interview (MMI) is now the most common medical school interview format in the UK and Australia. Instead of one long conversation with a panel, you move through a circuit of short stations, each run by a different assessor and each testing a different quality. A weak answer at one station does not follow you to the next, and no single interviewer decides your fate.
That structure is the point. Medical schools adopted MMIs because they are fairer and more reliable than a single panel: several independent scores predict how a candidate will behave on the wards better than one impression does. Understanding how the circuit works, and what each station is measuring, takes most of the fear out of it.
How An MMI Circuit Works
Most schools run between six and ten stations. Each lasts around five to ten minutes, often with a minute or two of reading time outside the room before you enter. A bell or an announcement moves everyone on at the same moment, so the timing is strict and the same for every candidate.
At each station you will usually find:
- A written prompt on the door or a card, which you read before entering
- One assessor, sometimes with an actor for role-play stations
- A short set of questions, or a task, followed by follow-up questions
- A scoring sheet the assessor completes after you leave
Your scores from each station are added together. The assessors do not confer, and most schools do not let them see your application, so every station is a fresh start. This is why the first-station nerves matter less than candidates fear: one shaky performance is a small fraction of the total.
Some schools now run MMIs online, with each station in a separate video room and a host moving you between them. The format is otherwise the same. Exact station counts, timings and delivery differ by school and change from year to year, so check your school's own admissions page rather than relying on forum posts.
The Station Types You Will Meet
Nearly every MMI draws its stations from the same set of qualities. Go Doctor's question bank is organised around nine of them, because they are what panels actually score.
- Motivation and insight. Why medicine, why now, and what you understand about the realities of the job. Expect "Why do you want to study medicine?" and its variations. Practise with motivation questions.
- Ethical scenarios. A dilemma involving consent, confidentiality, resources or a colleague's behaviour. You are scored on your reasoning, not on reaching a particular verdict. See ethical awareness questions.
- Role play. An actor plays a patient, relative or colleague and you are asked to talk with them. Common set-ups include an anxious patient, someone who has been given bad news, or a friend who has done something wrong. Practise with empathy questions and communication questions.
- Behavioural and teamwork questions. "Tell me about a time you…" prompts about teamwork, conflict, leadership or failure. Start with behavioural judgement questions.
- Reflection and resilience. How you handle setbacks, feedback and stress. See reflection and resilience questions.
- Professionalism and NHS values. Honesty, boundaries, accountability, and what you would do about a colleague who is struggling or behaving badly. Browse professionalism questions.
- Task stations. Some schools include a data interpretation exercise, a short calculation, a prioritisation task or a group discussion. These test how you think under time pressure rather than specialist knowledge.
You will not meet all of these at one school, but you will meet most of them across a season of interviews.
What Assessors Are Scoring
MMI stations are marked against a rubric, and the rubric is usually simpler than candidates imagine. Assessors are typically scoring:
- Structure. Did you organise your answer, or did you talk until the bell?
- Reasoning. Did you explain why, weigh alternatives and acknowledge trade-offs?
- Communication. Were you clear, appropriately paced, and did you listen to the follow-up rather than answering the question you rehearsed?
- Empathy and professionalism. Did you stay patient-centred and behave the way a good junior doctor would?
- Insight. Do you understand what medicine actually involves, including the unglamorous parts?
Notice what is missing: encyclopaedic knowledge and charisma. A quiet candidate who reasons clearly beats a confident one who picks a side and refuses to consider the other.
Inside A Station, Minute By Minute
Knowing the rhythm of a station helps you use the time well.
- Reading time. Read the prompt twice. Identify what kind of station it is and which framework fits: MIRR for motivation, STARR for a behavioural example, the four ethical principles for a dilemma, EMP or SPIKES for a role play. Decide your opening line before you walk in.
- The opening. Answer the question in your first sentence or two. Do not spend a minute on preamble; the assessor has heard it many times and it earns nothing.
- Development. Give your reasoning or your example with enough detail to be credible. For a scenario, name the people involved and what is at stake for each of them.
- The follow-up. Expect the assessor to push: "What if the patient still refuses?" or "What would you have done differently?" This is where most marks are won or lost. Engage with the challenge honestly rather than repeating your first answer.
- The close. Land a clear conclusion. If the bell goes mid-sentence, finish the sentence and stop. Assessors know the timing is tight.
Between stations, let the last one go. Assessors watch for candidates who carry a bad station into the next one, and resetting quickly is itself a mark of resilience.
Online MMIs
If your interview is online, the substance is identical but a few practical points matter. Test your camera, microphone and connection the day before. Sit somewhere quiet with a plain background and your face well lit. Look at the camera rather than the screen when you speak, and pause slightly before answering, because audio delay makes interruptions more likely. Have water and a pen to hand, and keep your phone elsewhere.
Common Mistakes At MMIs
- Answering the rehearsed question rather than the one asked. Listen to the wording. "Tell me about a time you showed leadership" and "What makes a good leader?" need different answers.
- Picking a side in an ethical scenario and defending it to the death. Assessors score how you weigh the tension, not your final verdict.
- Treating role play as a test of medical knowledge. You are being scored on listening, empathy and honesty, not diagnosis.
- Running out of time on preamble. Get to the answer.
- Letting one bad station spill into the next. Every station is scored independently. Use the walk between rooms to reset.
How To Prepare For An MMI
- Learn the station types. Work through Go Doctor's medical school interview question bank one category at a time until no theme feels unfamiliar.
- Practise out loud, to a clock. Reading model answers is not preparation. Set a timer for the station length your school uses and speak your answers.
- Rehearse follow-ups. Ask someone to challenge each answer with a "what if" question, or use Go Doctor's AI interviewer, which probes based on what you actually said.
- Run a full timed circuit. At least once before interview week, do six or more stations back to back, with the transitions, so the pace on the day feels normal.
- Check your school's format. Confirm station count, timing and whether it is in person or online, from the school's own admissions page.
