An interviewer finishes their question. You understand the words, but you have never considered the problem before. Where do you begin?
Start by making your reasoning visible. Explain what you understand, choose a useful starting point and work through the problem one step at a time. You can develop an answer during the conversation.
This guide focuses on academic university interviews, particularly the subject discussions used at Oxford and Cambridge. Other interviews, including multiple mini interviews, portfolio discussions and auditions, have their own formats. Check your course guidance and invitation before deciding how to prepare.
What an unfamiliar question can reveal
Oxford describes its interviews as an opportunity to explore your academic thinking. You may encounter unfamiliar ideas, work through a problem aloud or respond to another perspective. Its published sample questions show how tutors can develop a discussion through follow-up questions and prompts.
That makes your explanation useful evidence: which ideas you connect, what assumptions you make and how you respond when a detail changes. Subject knowledge still matters. Practise using the concepts from your course and the reading you have genuinely explored.
A four-part routine to practise
The following routine is Flyers Academy's practice framework. Use it flexibly; a conversation will often move back and forth between the steps.
1. Pause and choose a starting point
Take a breath. Identify the main task: are you being asked to explain a mechanism, compare two ideas, interpret evidence or defend a judgement?
You might begin, “Let me think about the main factors involved.” Then give yourself a moment to organise them. Aim to offer a useful first thought rather than fill every second with speech.
2. Clarify the detail that matters
If a word or condition is ambiguous, ask one focused question. A question about whether a policy is “successful”, for example, could depend on whether success means lower costs, wider access or a better outcome for a particular group.
If the interviewer leaves that choice to you, state your interpretation and proceed: “I'll take success here to mean that more students can use the service.” You have now made your assumption available for discussion.
3. Reason through a small, clear explanation
Select one relevant idea and explain why it helps. A useful sequence is:
- What do I already know that applies here?
- What would I expect to happen, and why?
- What evidence or example would help me check that expectation?
Keep a distinction between an observation and your explanation for it. “These two things happened together” leaves open the question of whether one caused the other.
For a quantitative problem, define your quantities and show your working. For a text or argument, point to the detail supporting your interpretation. Give the interviewer enough information to follow the route you are taking.
4. Reconsider when new information arrives
A follow-up question can add a constraint or expose a gap. Listen to it carefully and update the relevant part of your answer.
For example: “That changes my assumption about who can access the service. I'd now want to separate those two groups.” Explain what changed and why. Revision is most useful when the listener can see the reasoning behind it.
A worked example: would longer library hours improve results?
Flyers practice example, created for this guide: A university extends its library opening hours. Would you expect students' academic results to improve?
A first response could identify a plausible mechanism: students who lack a quiet place to work may gain more study time. You could then make the scope clearer: are we discussing examination results, assignment quality or access to study facilities?
Suppose you focus on examination results. Your explanation might develop like this:
“Longer hours could help students whose schedules or living arrangements make studying difficult. I would expect the benefit to vary between students. I'd want to know who uses the extra hours and what other study spaces are available.”
Now imagine a follow-up: the students using the late opening hours already achieved higher grades before the change.
You have a reason to refine the explanation:
“Their later results would be hard to interpret on their own. Prior attainment could explain part of the difference. I'd want information from before and after the change, and a comparison that accounts for differences between the students.”
You could also consider what else changed during that period: teaching, assessments or other support. Each step makes the question more precise and identifies evidence that would help answer it.
This example illustrates a way to develop an argument. Your own subject may call for a diagram, calculation, close reading or another method.
Try a short practice session
Set aside about 20 minutes with a teacher, friend or family member. Cambridge's preparation guidance encourages practice expressing your own ideas, including with someone who does not know you well.
Use the first few minutes to choose an accessible question linked to your subject. Spend the next part discussing it, with your partner adding a follow-up such as “What assumption are you making?” or “What evidence would change your view?” Finish by reviewing the explanation together.
Try one of these original Flyers practice prompts:
- Science: A plant grows faster under a new lamp. How would you investigate what caused the difference?
- Engineering: Two bridges use the same amount of material. What else would you need to know to compare their strength?
- Humanities: What could two conflicting accounts of the same event help a historian investigate?
- Economics: A town makes its buses free. What would you examine to judge the effects?
Afterwards, ask your partner where your explanation was easiest to follow and where a step was missing. Choose one improvement for the next attempt. The suggested timing and prompts are practice ideas, not an official interview format or assessment scheme.
Prepare the material and the practical details
Revisit your application, any submitted work and the books or projects you mentioned. Be ready to explain a specific idea, a decision you made or a question that remains open for you. Use the university's official sample material to understand the kind of discussion relevant to your course.
UCAS recommends checking interview arrangements in advance. Confirm the time, location or online platform, required equipment and any instructions about materials. Contact the university promptly if you need clarification or access arrangements.
For an online interview, test your connection and audio with another person. For an in-person interview, plan your journey and arrival time. Follow the invitation's rules about notes, devices and external assistance.
Make your next practice attempt useful
Pick one question this week. Explain a first idea, invite a follow-up and notice how your answer develops. Keep a short note of what you understood more clearly by the end.
