What Actually Happens in an MMI Station

The Shape of an MMI Day

An MMI isn’t one interview, it’s a circuit of short stations, usually somewhere between six and twelve, each run by a different assessor with its own scoring sheet. You rotate between them on a timer, answering something different at every stop.

Mine was run online, with two interviewers and a student helper watching each station. Every station lasted five minutes, but within that five minutes I was asked four separate questions with a strict one minute to answer each. I hadn’t expected that. I’d prepared to talk for most of the five minutes on each scenario, so compressing an answer into sixty seconds, four times over, caught me off guard.

Research the Actual Format Before You Assume Anything

Every university runs this differently. Some interview online, some in person. Some give you one long prompt per station, others break it into several short questions like mine did. Candidates who interview in person often describe sitting in a silent waiting room, reading a printed prompt on a clipboard before they’re called in, which is a completely different experience to reading a question off a screen. Look up how previous applicants describe the specific university’s process, on forums or wherever you can find it, rather than assuming your prep matches what’s actually coming.

What Each Type of Station Is Actually Testing

Ethics and NHS values stations

I had a station built around vaccine resource allocation: who should get access first when supply is limited. There’s no single correct answer they’re looking for. What’s being scored is whether you can structure your reasoning, weigh more than one side of the problem out loud, and sit with the uncertainty instead of rushing to a verdict just to sound decisive.

Reflection and teamwork stations

One station asked me to describe a time I worked in a team, faced a problem, and had to overcome it. I’d already prepared a specific story about a team mistake and what I learned from it before I walked in, and I used it as something I could adapt to whatever the exact question turned out to be. That’s the useful habit here: have two or three real stories ready, not a rehearsed answer for every possible question, and practice bending them to fit whatever’s actually asked.

The deliberately strange questions

Some stations exist purely to watch how you think, not what you know. A friend of mine was asked how much a mountain weighs. There’s no right number, and they’re not expecting one. What they want to see is you reasoning out loud: breaking it down by estimating the mountain’s size, comparing it to something with a known density, and working toward a rough answer step by step. Treat these as a chance to show your thinking, not a test you can fail by guessing wrong.

Don’t skip the obvious question

Somewhere in the circuit, expect a straightforward why medicine question. It’s easy to assume a question like that is too basic to need real preparation, but it deserves the same thought as everything else.

One Bad Station Doesn’t Sink You

Each station is scored completely separately by an assessor who has no idea how you did anywhere else. That’s genuinely good news: a station that goes badly doesn’t follow you to the next one. The only way it hurts you is if you let it, by carrying the frustration into the next room and losing focus there too. The skill worth practicing isn’t just answering well, it’s resetting completely between stations. Mock practice is where you build that: when you make a mistake in a practice run, the goal isn’t to avoid mistakes, it’s to practice moving past one without dwelling on it.

Use Your Reading Time to Build a Structure, Not a Script

You typically get a minute or two to read the prompt before you go in. Use it to sketch a rough shape for your answer, the two or three points you want to hit and the order you’ll hit them in, rather than trying to compose full sentences in your head. Walking in with a structure means you can actually listen and adapt once you’re in the room, instead of reciting something you wrote in your head thirty seconds earlier.

Do Your Homework on the Specific University

Before the day itself, look up what previous applicants to that specific university have said about their experience. Forums and student communities are full of first hand accounts of format, timing, and the kinds of stations that come up. It won’t tell you exactly what you’ll get, but it narrows the number of surprises waiting for you on the day.
