The format
A timed circuit of short, independent stations — not one continuous conversation like the traditional interview.
The Multiple Mini Interview (MMI) replaces the traditional single-room interview with a circuit of short, timed stations. At each station, a different assessor evaluates a single attribute — ethical reasoning, communication, teamwork, or motivation — independently of every other station. You then rotate to the next station on a bell.
In the US, MMI use has grown but remains a minority format — most MD programs still use some form of traditional 1-on-1 or panel interview. Many DO programs use the MMI, and the format is expanding at MD programs with strong community and social-accountability missions.
Rotate through independent stations — a weak performance at one never carries into the next. Each station is a genuine fresh start with its own rater.
Format varies by school. The number of stations, station duration, and use of standardised patients vs faculty raters all vary. Always verify the current format on your school's admissions website — programs sometimes change delivery method between cycles.
The rationale
The station-based design solves two core problems with panel interviews: the halo effect and inter-rater unreliability.
A different rater scores each station, so no single strong or weak first impression — the halo effect — can dominate your whole evaluation.
Sampling many short, independent stations measures you far more reliably than one continuous conversation with a single panel.
Research in the BMJ and Academic Medicine has found MMI scores predict clinical clerkship performance better than traditional interview scores.
Where
These schools have used MMI-format interviews in recent cycles. The list is representative, not exhaustive — formats change, so always confirm with the school directly.

Station playbook
A typical circuit mixes several station types. Most schools do not announce in advance exactly which you will encounter.
A morally complex prompt — resource allocation, end-of-life care, confidentiality — requiring structured ethical reasoning. There is no single correct answer; stations assess your reasoning process, not your conclusion.
Prep tip
Use a principlist framework (autonomy, beneficence, non-maleficence, justice). Acknowledge competing perspectives before reaching your view.
You interact with an actor (standardised patient) playing a patient or colleague. You may be asked to explain a diagnosis, address a complaint, or deliver difficult news.
Prep tip
Establish rapport first. Check understanding throughout. SPIKES (Setting, Perception, Invitation, Knowledge, Empathy, Summary) is a standard scaffold.
Often overlaps with communication stations. You play a doctor, nurse, or student and navigate an interpersonal challenge — an upset patient, a disagreement with a colleague, or a difficult consent conversation.
Prep tip
Listen actively before problem-solving. Avoid defensive language. Demonstrate empathy even if the actor is hostile.
A group or dyadic task assessing whether you can work constructively with others. Some schools use it to observe leadership, conflict resolution, and task allocation.
Prep tip
Share the floor. Acknowledge others’ contributions. Do not dominate or passively opt out.
“Tell me about a time you faced a challenge.” “Describe a situation where you had to give critical feedback.” Assesses self-awareness and values using real-life examples.
Prep tip
Prepare 5–7 distinct experiences you can adapt to different prompts. Use STAR (Situation, Task, Action, Result) for structure without sounding scripted.
Some MMI circuits include one or two stations that look more like mini traditional interviews — “Why do you want to be a doctor?”, “Why our school?”, or a current-affairs / health-policy question.
Prep tip
These are still time-limited. Prepare concise, authentic answers. Do not deliver a rehearsed speech — adapt to the follow-up questions.
Toolkit
When you meet an ethical or dilemma-based prompt, use the 4Cs to structure your response rather than jumping straight to a conclusion.
Identify what is actually being asked. Define your role in the scenario. Surface any ambiguities before reasoning through them.
Name the ethical principles at stake — autonomy, beneficence, non-maleficence, justice. Identify whose interests conflict and why.
Explore at least two competing perspectives. Acknowledge consequences, stakeholders, and practical constraints. Show that you have genuinely weighed alternatives.
State your reasoned position clearly. Acknowledge limitations and remaining uncertainty. Avoid false certainty or moralistic over-confidence.
The 4Cs is one useful scaffold, not an algorithm. Raters are assessing whether you think carefully under time pressure — not whether you can recite a framework by name. Internalise the logic, then let your response sound like a thoughtful person, not a textbook.
Logistics
Since COVID-19, many US schools have retained a virtual MMI option. Three platforms dominate — and each needs a slightly different prep approach.
Asynchronous video platform. You read a prompt then record a response within a set window — typically 2 minutes to read, then 2–5 minutes to respond, with no live interaction. Used widely by DO programs (ACOM, MSUCOM) and some MD programs for pre-interview screening. What you read is what you get — you cannot clarify the prompt.
Prep for Kira: practise recording yourself on a timer and watch the playback. Eliminate filler words, long pre-start pauses, and looking down at notes. Test your camera and microphone first.
Live video platform used by some schools for synchronous virtual MMI delivery — each station has a live rater on screen, and the bell and rotation are managed by the platform. More similar to an in-person MMI than Kira.
Prep as you would for in-person MMI, with extra camera-eye-contact practice.
Some schools run virtual MMIs directly via Zoom or Teams with faculty-moderated rotations. Format and timing are managed by the school’s admissions team.
Check whether your school uses a third-party platform or its own setup.
Note: dental-school applicants applying through ADEA AADSAS may also encounter virtual MMI formats. The prep principles are the same.
Pitfalls
The avoidable errors that cost candidates marks station after station.
The bell cuts you off whether you have finished or not. Practise ending 20–30 seconds early to allow for follow-ups. Unfinished responses are evaluated on what was said, not what you intended to say.
Generic frameworks without direct reference to the scenario’s details signal memorised answers. The specific context — who is involved, what stakes are at play — should drive your response.
A stilted, “presenter” tone on Kira Talent or Zoom usually reflects over-rehearsal. Raters want genuine engagement and natural reasoning, not a polished delivery. Allow a realistic, conversational quality.
A poor station feels significant, but it contributes only 1/N of your total score. The best recovery is full presence in the next station — do not let rumination bleed into later performance.
In ethical stations especially, an immediate confident verdict — without acknowledging competing considerations — signals black-and-white thinking. Use the reading time to identify the tension first.
Communication stations assess your responsiveness. If the actor gives emotional cues and you deliver a monologue ignoring them, you fail the station’s purpose. Pause, listen, and respond to the person.
Context
How the admissions landscape since SFFA v. Harvard shapes the scenarios you should prepare for.
Following SFFA v. Harvard (2023), many US medical schools have revised how they assess commitment to diversity, equity, and inclusion in admissions. In MMI practice, this manifests as scenarios that probe health equity, cultural humility, social determinants of health, and service to underserved communities — without explicitly referencing race. Applicants should be able to discuss real experiences engaging with diverse or underserved populations, explain their understanding of structural barriers to healthcare access, and demonstrate genuine — not performative — commitment to community service. Prepare specific examples, not generic talking points.
