Oxford Engineering Science interview

The Oxford Engineering Science interview is academic and run like a tutorial. Tutors usually start with why you want to study engineering and why Oxford, then move to maths and physics problems based on school topics. Expect a scenario you haven't met before: tutors want your prediction and reasoning, then help you express it mathematically. Shortlisted candidates have two interviews of about 30 minutes at two different colleges, online on Microsoft Teams, and for 2027 entry most run from 14 to 16 December 2026.

Key facts

What happens in the interview

Oxford Engineering Science interviews are academic and mostly maths and physics problems based on school topics. The first interview usually opens with why engineering and why Oxford, or something on your UCAS form, such as projects, hobbies or work experience. The second may be maths and physics only.

Expect a curve to sketch or a quantity to estimate, then a physical scenario to explain and express mathematically, such as forces, moments, friction, energy or circular motion. A warm-up comes first. An unfamiliar engineering problem, such as a ruler balanced on two fingers or designing a gravity dam, comes later.

Tutors run it like a tutorial:

• They ask for your prediction first, then your reasoning.
• They prompt you when you're stuck, for example "start by considering the forces acting on it".
• They give guidance on material you haven't met, and watch how fast you pick it up.
• Then they go quantitative, for example asking for an expression for stability.

Needing help is expected and doesn't count against you. Little slips aren't a big deal, and tutors don't expect everyone to reach the end of a question.

You'll work on a shared Miro whiteboard with a stylus, so have a touchscreen of at least 8 inches, a basic stylus, and paper and pens. Don't erase anything on the board: cross mistakes out.

What tutors look for

Oxford's Engineering Science tutors look for the following, drawn from the department's published criteria:

• Fluency in maths and physics: expressing core knowledge and ideas in physics and maths fluently, including turning a physical situation into equations.
• Applying knowledge to new situations: methodically applying existing physics and maths to an unfamiliar engineered system, identifying the forces, predicting what happens and judging how it could fail.
• Picking up new concepts quickly: assimilating and applying a new concept or hint, with rapidity in thinking and reasoning.
• Commitment and enthusiasm for engineering: commitment to intense and sustained learning, and interest in and enthusiasm for the engineered world.
• Explaining your thinking: talking through ideas clearly while sketching and calculating, so tutors can follow the reasoning.

How the interview is marked

Oxford doesn't publish how Engineering Science interviews are scored, so there is no public marking scale.

What is published: shortlisting and offers weigh your UCAS application, the admissions test and the interviews together, with no set weighting for any one part. The department says needing help won't count against you, and tutors in Oxford's official demonstration interview say they don't intend every candidate to reach the end of a question.

Example questions

These are questions Oxford has published, in the form Toby asks them. Tutors set their own questions, so yours will differ.

Ruler on two fingers

Published by Oxford: sample interview questions

Place a 30 cm ruler on top of one finger from each hand so that you have one finger at each end of the ruler, and the ruler is resting on your fingertips. What happens when you bring your fingers together? (Try it slowly if you have a ruler or a pen to hand.)

• Why tutors ask it: it shows whether you can explain a surprising everyday observation precisely with moments and friction, and then build a model of it.
• A hint a tutor might give: "Do both fingers slide under the ruler at the same time, or one at a time?"
• A strong answer makes a prediction first, then tries it or takes the hint. It explains what it sees as a clear chain of reasoning about where the ruler's weight acts and what each finger is carrying, and then builds a simple model of the motion.
• A common slip is assuming each finger carries half the weight wherever it is.

Lifting an elephant by balloon

Published by Oxford: sample interview questions

How hot does the air have to be in a hot air balloon if I wanted to use it to lift an elephant? Before any numbers: why does a hot air balloon rise at all?

• Why tutors ask it: it shows whether you can find the core physics behind a balloon, make sensible estimates and put them together into an answer you can check.
• A hint a tutor might give: "What makes a cork float in water? Is something similar happening here?"
• A strong answer explains why the balloon rises before using any numbers, then says what it's estimating and assuming at each step, counting the balloon itself as well as the elephant. It finishes by asking whether the result is realistic.
• A common slip is using Celsius instead of kelvin when comparing hot and cold air.

Designing a gravity dam

Published by Oxford: sample interview questions

How would you design a gravity dam for holding back water? (A gravity dam is a massive concrete wall held in place by its own weight.) To start: what forces act on it, and in what ways could it fail? Sketch a cross-section.

• Why tutors ask it: it shows whether you can identify the forces on a structure, model the water pressure, and turn the ways it could fail into simple design conditions.
• A hint a tutor might give: "Imagine standing on the dry side. What is the water trying to do to the wall?"
• A strong answer lists every force on the wall, including those from the ground at its base, before naming the ways it could fail. It models how the water pressure varies over the face of the dam, then turns each way of failing into a condition on the dam's width and says which one decides the design.
• A common slip is using the pressure at the bottom over the whole face of the dam.

Practise with Toby

Toby is an AI interviewer that runs practice interviews by voice. The Oxford Engineering Science interview is built from Oxford's own guidance and follows the real format:

• First college. Why engineering and why Oxford, and perhaps something from your personal statement, then a maths question such as a curve sketch or an estimate, and a physical scenario explained and then expressed mathematically with the tutors' help.
• Second college. At a second, pre-assigned college: maths and physics problems only, often an unfamiliar engineering scenario (friction, forces, stability, energy) taken from a qualitative prediction to a simple quantitative model.

It draws on 38 problems, each with hints and follow-ups. Thirteen are questions universities have published, and the rest were written to the same style and level, with every result independently re-derived.

Toby puts the problem on screen, gives you time to think and asks you to talk it through. He asks for your prediction before your reasoning, gives a hint only when you're stuck, and then helps you turn your reasoning into a simple model. Like a real tutor, he doesn't praise every answer.

You can add your personal statement so Toby can ask about it, and choose a 10, 20 or 30-minute interview. Your prep page has the format, the department's criteria and practice problems with hints and worked solutions. Afterwards, your debrief gives you a practice mark out of 10 (6 is acceptable, 7 good, 8 strong), a score against each criterion, notes on every question and the full transcript. A practice mark is a guide, not a prediction.
