MMI Practice Questions: Stations, Timing, and How to Answer

A multiple mini interview is a circuit of roughly 6 to 10 short stations. At each one you get about 1 to 2 minutes to read a prompt in the corridor, then 5 to 8 minutes inside the room with a fresh assessor who has never met you. The stations test ethics, situational judgement, teamwork and communication rather than scientific knowledge, so practising for one means rehearsing how you reason out loud against a clock, not memorising answers.

What is a multiple mini interview?#

It is an interview broken into pieces. Instead of one panel forming a single impression of you over 40 minutes, you rotate through a series of independent stations, each with its own prompt and its own assessor. Nobody at station four knows what happened at station three. The format comes out of McMaster University's medical school and was described in Medical Education in 2004 (Eva KW, Rosenfeld J, Reiter HI, Norman GR, "An admissions OSCE: the multiple mini-interview," Med Educ 2004;38(3):314-26, PMID 14996341).

The structural consequence matters more than the trivia. In a single-panel interview, one bad opening minute follows you for the rest of the hour. In an MMI, a station that goes badly is over in minutes and the next assessor starts you from zero. That cuts both ways: it protects you from one poor first impression, and it means a strong rapport you built at station one buys you nothing at station five. Each station stands alone.

That also explains why the content is what it is. You cannot test recall of biochemistry in short slices with lay assessors and actors in the room. You can test whether someone can hold two competing obligations in their head, say something honest about the harder one, and stay listenable while doing it.

What actually happens on the day#

The mechanics are more physical than most people expect, and the physicality is half of what throws candidates.

You are given a candidate number and a starting station. The prompt is on a sheet taped to the door or handed to you in the corridor. A bell, a buzzer, or a voice over a speaker starts your reading time, and you stand there in a line of other candidates reading their own prompts. One to two minutes later the signal goes again and you walk in.

Inside there is usually one assessor with a scoring sheet. Sometimes there is also an actor. The assessor may say almost nothing, may not react to anything you say, and will often not smile. That is deliberate and it is not feedback. They are scoring against a sheet, not conversing with you. Some assessors will interrupt with probing questions the moment you stop; others will let silence sit.

Then the signal goes again, mid-sentence if that is where you are, and you leave. There is no wrap-up. You walk back into the corridor, stand at the next door, and read a completely unrelated prompt while still replaying the last one.

Two practical points fall out of that:

• Expect to be cut off at least once. The bell landing mid-sentence is a normal feature of a timed circuit, not a verdict on your answer. Plan for it by front-loading your position rather than saving it for a grand conclusion.
• The reset between stations is its own skill. A bad station costs you one station. Carrying it into the next two costs you three. Ten seconds in the corridor spent on the new prompt instead of the old room is worth more than any memorised answer.

What MMI stations actually assess#

Four things, mostly, and none of them is what you revised for your exams:

• Ethics. Not whether you land on the "correct" answer, but whether you can see the competing obligations and say why you would weigh them the way you do.
• Situational judgement. What you would actually do, in what order, in a messy scenario with no clean option.
• Teamwork. How you behave when someone else has information you need, or is underperforming, or disagrees with you.
• Communication. Whether a person on the other side of the table can follow you, and whether you noticed how they were reacting.

Scientific knowledge is not the point. If a station happens to touch a clinical topic, it is almost always a vehicle for one of the four above.

MMI practice questions by station type#

The prompts below are practice prompts written for this guide. They are not real questions from any specific school, and no school's circuit is public. Use them as reps, not as predictions. Not every programme uses every station type, and some use types that are not on this list. Your invitation email and the school's admissions page are the authority on what your circuit contains.

Ethical dilemma stations

Practice prompts:

• A close friend on your course tells you they have been drinking before clinical placements. What do you do?
• Should a publicly funded health service pay for treatments where the patient's own choices contributed to the illness?
• A patient refuses a treatment you believe would help them, for reasons you think are mistaken. How do you approach it?

How to use the room: the failure mode here is picking a side in the first sentence and then defending it for six minutes. These stations are built around dilemmas that do not have one clean answer, so the verdict is rarely the interesting part. What you are being read on is whether you saw the thing that makes it hard.

A spine that survives a probing assessor:

1. Name the tension in one sentence. "The difficulty here is that my duty to my friend and my duty to the patients on that placement point in opposite directions."
2. Lay out both obligations properly, giving the one you will not follow its strongest version, not a straw man.
3. Say what you would actually do, in order. Concrete steps, first action first. "I would speak to them directly before anyone else, because..."
4. Name what would change your mind. "If they told me they had already self-reported, my next step changes, because..."
5. Stop. Do not fill the remaining time.

Role-play stations with an actor

Practice prompts:

• Your teammate has missed three deadlines on a group project and the final submission is Friday. Speak to them.
• You organised a group trip that has just been cancelled. Your friend does not yet know. Tell them.
• A colleague has made a small mistake that nobody else noticed. Raise it with them.

How to use the room: the actor is briefed to react to how you behave, and often to escalate if you switch into information-delivery mode. The most common mistake is treating the person as a problem to be solved rather than a person to be spoken to.

Practical moves that hold up: acknowledge the person before you address the problem; ask before you tell; leave silence after bad news instead of filling it with logistics; and check they have understood at least once, in their words rather than yours. If the actor becomes angry or tearful, that is the station working as designed, not you failing it.

Note that it is you being assessed, not the actor's mood. An actor who stays upset is not by itself a failed station; the station is asking how you handled a person, not whether you fixed them in six minutes.

Teamwork and collaboration stations

Practice prompts:

• You and another candidate each hold half the instructions for building a shape. Neither of you can see the other's sheet. Build it in four minutes.
• Agree with another candidate on how to allocate a limited budget across three competing departments.

How to use the room: the task is a pretext, and finishing it is rarely the point. These stations exist to watch collaboration and communication, which means what shows is whether you narrated your reasoning so the other person could work with it, whether you asked for theirs, and whether anyone managed the clock out loud.

Say the quiet parts audibly. "I have three instructions, let me read all three before we start." "We have about a minute left, so let me check we agree on the base." Being silently competent gives the assessor nothing to observe.

Motivation stations

Practice prompts:

• Why medicine?
• Why this school?
• What would you do if you did not get in this year?

How to use the room: specific beats noble every time. "I want to help people" is the most common opening sentence in the building that day and it distinguishes nobody.

Build it from one concrete moment: what you actually saw or did, what it changed in how you thought, what you did next as a result, and what you now understand about the job that you did not understand before. The last part is what separates a considered applicant from an admiring one. It is also where honest limits help you: naming a part of the work you found harder than expected reads as someone who has looked at the real thing.

Data, prioritisation, and policy stations

Practice prompts:

• You are a doctor with four patients booked into the two appointment slots you have left. Who do you see, and on what basis?
• Here is a graph of waiting times over five years. What does it show, and what would you want to know before drawing conclusions from it?

How to use the room: state your criterion before you apply it. "I am going to prioritise on clinical urgency first, then on who is least able to wait safely." Then apply it out loud and say what you are trading away. On data prompts, describe what the chart actually shows before interpreting it, and name at least one thing it cannot tell you.

How do I structure an answer in five to eight minutes?#

Three habits do most of the work.

Use the reading minute for a spine, not a script. You cannot write an answer in 90 seconds, and trying to produces a recitation you then read off the inside of your own head. Write three or four words: the tension, your first action, your caveat. That is enough to keep you oriented when the assessor's silence makes you lose your place.

Budget roughly half the time for yourself. The two common failures are sprinting through in two minutes and then sitting in dead air, or monologuing for eight and getting cut off. Aim to make your case in three to four minutes and leave room for the probe. The follow-ups are where the assessor finds out whether you meant any of it, so they are not the part to run out the clock on.

Hold something in reserve. Deliberately keep one counter-argument or one practical complication back. When the assessor asks "is there anything else?" or pushes on the weak point, you have somewhere to go that is not repetition. Repeating yourself louder is the most visible symptom of having run out of thinking.

If you do run dry with time on the clock, the honest recovery works better than filler: "I think I have covered my main reasoning. Can I add the one thing I would want to check before acting?" That reads as control. Circling back through your own points reads as panic.

How do the US and UK cycles differ?#

The format is broadly the same on both sides; the calendar and the surrounding process are not.

Two consequences worth planning around:

• US applicants get less warning but a longer runway. Invitations start landing from mid-August 2026 for a window that opens in October, so the gap between "invited" and "interviewing" can be short. Start practising before your first invitation, not after.
• UK applicants peak later, and Oxbridge peaks hardest. With Oxbridge concentrated in the first three weeks of December, a candidate holding several offers of interview can face multiple formats inside a fortnight, in the middle of term. Book the practice into December's calendar before December fills itself.

Interview format also varies by institution within both countries. Some programmes run a panel rather than an MMI, some run a hybrid, and some have moved between formats between cycles. Check what your specific programme is running this cycle rather than assuming.

Is Casper part of the MMI, and what happened to Snapshot?#

No, Casper is a separate thing, and this is where a lot of published advice is out of date.

Snapshot, the recorded-video component that used to sit alongside Casper, is no longer part of it. Plenty of prep content still describes it as a current requirement. If a guide is telling you to record a Snapshot video, that guide is out of date, and it is worth asking what else on it is.

Acuity Insights, which runs Casper, no longer references Snapshot anywhere on its Casper pages. As of 3 August 2026 those pages describe Casper as "an open-response situational judgment test that measures aspects of your social intelligence and professionalism, like ethics, empathy, problem-solving and collaboration," with no Snapshot component named (acuityinsights.app). We have not found a dated retirement announcement from Acuity, so treat the absence rather than any particular cycle date as the fact: check your own programs' requirement pages, because a program can ask for something its vendor no longer bundles.

The distinction that matters for your prep: Casper is a test you sit on your own, at a computer, before any interview. An MMI is a live circuit with assessors and, often, actors in the room. They overlap in subject matter, because both push on ethics and situational judgement, and reasoning practice transfers between them. They do not overlap in delivery. Nothing about typing a considered answer alone prepares you for saying one out loud to a stranger who does not react.

Requirements differ by programme and change between cycles, so confirm what your programme requires this cycle from the programme itself.

How do I practise this when I am on my own?#

The two hardest constraints to recreate alone are the clock and the audience. Most solo practice quietly removes both: you think about a prompt, decide roughly what you would say, and move on. That builds nothing, because the gap on the day is never "I did not know what I thought." It is that thinking it and saying it fluently in five minutes to an unresponsive stranger are different skills.

What actually reproduces the pressure:

1. Set a real timer and speak out loud. Not in your head. Out loud, standing, at full volume.
2. Use a prompt you have not read before. Have someone else pick from a list, or number the prompts and pick at random. Reading a prompt you already considered last week tests recall, not thinking.
3. Record it and watch it back once. Once, not five times. You are looking for the specific places you stalled, hedged, or repeated a point, not for reasons to feel bad.
4. Rehearse the corridor. Practise two prompts back to back with 60 seconds between them, so the reset gets reps too.
5. Get a second pair of eyes on the ethics stations. Your own blind spot is the obligation you find it easy to dismiss, and by definition you will not spot it alone.

Now the honest part about our own tool. UnchartedCareer cannot simulate an MMI. Our product runs a single continuous conversational interview with one interviewer. An MMI is a timed circuit of separate stations, each with a new prompt and a new assessor who knows nothing about how the last one went. Those are different formats and we are not going to describe ours as something it is not.

What it does exercise is the skill underneath every station: speaking a structured answer out loud, under time pressure, to a prompt you have not seen, without rambling, and then hearing how you actually sounded. It returns a written report scored on content, delivery, and, if your camera is on, body language, and we publish the exact weights it uses. Treat it as reps on delivery, not as a dress rehearsal for the circuit. For the circuit itself, you need the timer, the corridor, and a person willing to sit there and not smile at you.

FAQ#

Q: What is a multiple mini interview? A: It is an admissions interview split into a circuit of roughly 6 to 10 short stations. You get about 1 to 2 minutes to read a prompt outside each room, then 5 to 8 minutes inside with a fresh assessor. Each station is scored independently, so a poor station does not follow you to the next one.

Q: How long is each MMI station? A: Typically 1 to 2 minutes of reading time outside the room and 5 to 8 minutes of response time inside it. The exact split varies by programme, and the school will usually tell you in the invitation. Being cut off mid-sentence by the bell is normal and is not held against you.

Q: What do MMI stations assess? A: Ethics, situational judgement, teamwork, and communication, rather than scientific knowledge. Even when a station touches a clinical topic, it is almost always a vehicle for one of those four.

Q: How do I prepare for an MMI? A: Practise out loud against a real timer, on prompts you have not read before, and record yourself once to hear where you stall or repeat. Rehearse the gap between stations too, since resetting after a bad station is a large part of the format. Reading model answers silently builds the least transferable version of the skill.

Q: Can AI interview practice simulate an MMI? A: Not as a circuit. UnchartedCareer runs one continuous conversational interview with a single interviewer, which is a different format from a timed multi-station MMI with a new assessor at each door. What a conversational mock does train is the shared skill underneath: answering an unseen prompt out loud, under time pressure, without rambling.

Q: Is Casper the same as an MMI? A: No. Casper is an open-response situational judgment test you sit on your own at a computer before any interview. An MMI is a live station circuit with assessors and often actors in the room. The subject matter overlaps, so reasoning practice transfers, but the delivery demands do not.

Q: Do I still need to complete Snapshot? A: No. Acuity Insights no longer names Snapshot anywhere on its Casper pages as of 3 August 2026, and we have found no dated retirement announcement to cite for exactly when that changed. Prep content that still tells you to record a Snapshot video is out of date. Check your own programs' requirement pages rather than a prep site.

Q: When are medical school interviews held? A: In the US, interviews run from October 2026 to January 2027, with invitations going out from mid-August 2026. In the UK, they run from late November 2026 into March 2027, with Oxbridge interviews concentrated in the first three weeks of December.

Q: How many stations does an MMI have? A: Usually somewhere in the range of 6 to 10, though individual programmes set their own circuits and some fall outside that range. Your invitation or the school's admissions pages are the only reliable source for your specific circuit.
