Cambridge Interview Questions: What Cambridge Actually Publishes

Cambridge does not publish sample interview questions. Its official interviews page, its preparation page and its statistics page carry none, and its own Computer Science department sends applicants to Oxford’s sample problems instead. With the main interview period running 7 December to 18 December 2026, this page maps what Cambridge genuinely publishes and what it means for your December.

That absence is the reason the search results for this term look the way they do. Every question list you will find was assembled by somebody other than the university, from memory, from forum posts, or from another list. Some of those questions are almost certainly real. None of them are official, and no page on the internet tells you which is which. What follows is an attempt to fix that: the actual Cambridge sources, what each one says, and where the reasoning behind a Cambridge-style question is worked through properly.

Does Cambridge Publish Its Own Interview Questions?

No. We read the full text of the three official pages an applicant is sent to, and none of them contains a single example question.

The official page on what to expect at your Cambridge interview runs to five sections — interview dates, interview format, why we interview, what happens in the interview, and after the interview. It gives the dates, a College-by-College table of online and in-person formats, and a list of the qualities interviewers assess. It gives no questions. The interview preparation page tells you to reread your personal statement, explore your subject beyond school, and practise talking about it. It supplies nothing to practise on.

Cambridge is also explicit about the commercial market that has grown into that gap. On the interviews page it warns, under its own heading, that “Some companies offer interview preparation for a fee. These services are not endorsed by the University. They do not have access to any exclusive information.” That is worth reading precisely. It is not a claim that preparation is useless. It is a claim that nobody, anywhere, is holding a secret list. Every question set in circulation — ours included — is reconstructed rather than issued.

This matters for how you use question lists. If no list is official, then the value of a question is not its provenance but whether working through it trains the thing Cambridge says it is measuring. A recalled question with no reasoning attached teaches you almost nothing. A representative question with the reasoning worked through teaches you the move.

Where Cambridge Points Instead, Including Straight at Oxford

Here is the detail that no other page on this search result appears to have noticed. The Cambridge Department of Computer Science and Technology interviews page does not link to any Cambridge question bank, because there is not one. It links to Oxford. In its own words: “You may also find it useful to look at this sample interview dialogue for an Oxford Computer Science interview (which is very similar to a Cambridge one).”

Under its “How to prepare” heading, the first item in its list of practice resources is “University of Oxford sample Computer Science interview problems”. A Cambridge department, on a Cambridge page, telling Cambridge applicants that the closest available published material is the other university’s.

Two things follow. First, Oxford material is legitimately useful for a Cambridge interview, and a Cambridge department has said so in writing — so you can stop worrying that practising on Oxford problems is somehow off-target. Second, if you have been searching for a Cambridge equivalent and finding only tutoring-company lists, that is not a failure of your searching. The equivalent does not exist.

The nearest Cambridge comes to publishing questions is on film. Christ’s College collects sample interview films covering Computer Science, Geography, History, HSPS, Medicine and Natural Sciences, noting that “The following films have been made by some of the other Colleges to give prospective students examples of what online interivews are like in specific subjects” Trinity College goes further and films full mock interviews in Engineering, Modern Languages and Natural Sciences, with a claim worth taking seriously: “The questions asked here by our interviewers are similar to those they have asked previously in interviews.”

That single Trinity sentence is the strongest provenance any published Cambridge interview question has. It is also the reason the films are worth more of your time than another list of one hundred one-liners.

What Cambridge Says Its Interviewers Are Actually Testing

If there is no question list, the assessment criteria become the planning document. Cambridge is unusually specific about them.

On a subject-specific interview, the official page says you are likely to “discuss topics with two or three interviewers” and to “apply your knowledge to new situations, materials, problems or scenarios”. For clinical courses it adds that you should “explain your understanding of vocational aspects of the course, if applying for Medicine, Veterinary Medicine, or similar courses”. On maths and science courses, “You may be asked to share your workings if the interviewers ask you a problem-solving question.”

The preparation page is blunter about the criterion underneath all of that: “the people interviewing you are interested in how you work out your answers and how you think”. Trinity says the same thing from the interviewer’s chair — “We are less interested in your conclusions than the methods you use to reach them.”

There is a second kind of interview that catches people out because it is rarely discussed. Alongside the subject interview, the official page says “Some applicants may also have a broader academic interview”, exploring your other academic interests, future plans and suitability for the course — and, critically, that “These interviews may be conducted by academics outside your subject area, but still assess your academic potential.” If you find yourself explaining your subject to somebody who does not work in it, that is not small talk and it is not a scheduling error. Explaining a technical idea to an intelligent non-specialist is one of the harder things the whole process asks of you, and it is worth rehearsing separately from your subject material.

Read those together and the practical instruction is clear. The interview is not a quiz with a mark scheme. It is a live demonstration of method. That is why silence hurts you more than a wrong turn: an unspoken thought cannot be assessed, and it cannot be helped. The Computer Science department page says so explicitly — “Your interviewers will give you hints if you get stuck or go in the wrong direction.” Hints are only available to a candidate who is audibly stuck rather than invisibly stuck.

Subject by Subject: The Cambridge Source, and Where Our Worked Questions Are

Below, each row pairs what a Cambridge department or College has actually published about its own interviews with the page on this site where questions of that shape are worked through in full. Where the Cambridge statement is general rather than subject-specific, we have said so rather than dressing it up.

Read down the middle column and the pattern is stark. Six subjects have a film. One has a department page describing the shape of its problems. The rest have nothing subject-specific at all, which is precisely why the reconstructed question sets on this site exist.

How Many Interviews Will You Have, and How Long?

Cambridge publishes this properly, so there is no need to rely on forum lore. The official page states: “Most applicants will have 1 or 2 interviews lasting a total of 35 minutes to an hour.” It adds that “Some may have 3 or 4 interviews, depending on subject and College.” It also says, twice and in different words, that neither the number of your interviews nor their timing reflects how strong your application is.

Underneath that headline, the arrangements vary by College in ways that change how you should prepare. The Computer Science department page spells three of them out. Gonville and Caius “have two 25-minute Computer Science interviews”. Peterhouse runs one 25-minute Computer Science interview and one 25-minute Maths interview. Churchill runs “one 30-40 minute Computer Science interview”.

Those are materially different tasks. Two shorter interviews means two openings and two closings, and two sets of interviewers forming an impression from scratch. One longer interview means a single problem can be pushed much further than you expect, and your stamina in the second half matters. If you are at Peterhouse for Computer Science, one of your two interviews is a Maths interview, which changes what you revise.

Format varies too, and it is set by College rather than by you. Our page on the Cambridge interview format by College carries the full table of which Colleges interview online and which in person. If you are not called in December, the winter pool route runs separately, with pool interviews around mid to late January 2027.

One practical consequence of an online interview is easy to leave too late. Trinity tells candidates in Chemical Engineering and Biotechnology, Computer Science, Engineering, Mathematics, Medicine and Natural Sciences that “you will need to have access to a graphics tablet” during a remote interview, so that interviewers can see what you write. Cambridge’s central preparation advice says the same thing more generally, telling science and maths applicants to practise using a stylus and tablet to annotate a shared document or whiteboard if their College has said one is needed. Writing mathematics legibly with a stylus while talking is a genuinely separate skill from doing the mathematics. Find out from your College which applies to you, then practise on the device you will actually use, not on paper.

Amazing tutors!

We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.

Great Teaching and Focused Learning

I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.

Which Cambridge Questions on the Internet Are Real?

Apply three tests to any list you find.

• Is it attributed? Almost none are. Trinity’s filmed questions are the rare exception, because the College states they are similar to ones its interviewers have asked before.
• Does it carry reasoning? A question with no worked path is a trivia card. The whole assessment is method, so a list without method trains the wrong muscle.
• Is it subject-shaped? Cambridge interviews are subject interviews conducted by subject academics. A general list of abstract puzzles rarely resembles what a Modern Languages or Land Economy candidate actually faces.

Judged that way, most of what ranks on this term fails at least two of the three. The list sites give volume without attribution or reasoning. The official Cambridge pages give attribution and criteria without questions. The genuinely useful combination — a representative question with the reasoning fully worked through — is the gap this site exists to fill.

There is one more trap worth naming. A cam.ac.uk page ranks highly on this exact search that has nothing to do with admissions: the University Careers Service interviews page, whose sections are “First interviews”, “Further interviews” and “How we can help”, and which is about graduate job interviews, panel interviews and assessment centres. If you land there expecting admissions guidance, you are in the wrong building.

Working a Question the Way the Department Describes It

Take the Computer Science department’s own description and run it as a method rather than as advice. It says the problems “almost always require mathematical knowledge and understanding to solve”, that interviewers “will not expect you to know things that are outside of your school curriculum”, and that they “do not expect you to fully complete all of the problems presented during the interview”.

That third clause is the one candidates ignore, and it changes everything about pacing. If finishing is not the target, then spending your first ninety seconds silently hunting for the elegant route is a strictly worse strategy than saying out loud what you notice, what you would try first, and why. The department describes solving a problem as “a bit like a conversation”, with you explaining your approach and the steps you are taking, and the interviewer supplying hints when you go wrong.

So the sequence to rehearse is not question to answer. It is:

1. Restate the problem in your own words, which catches misreadings before they cost you five minutes.
2. Name what you notice — a symmetry, a constraint, a special case — even if you cannot yet use it.
3. Try the smallest case out loud. Almost every problem-shaped interview question yields something at n equals one or two.
4. Say what you would need to generalise, and let the interviewer either confirm it or redirect you.
5. Check the answer against a sanity case before declaring it, and say what you are checking.

Every one of those steps is externally audible. That is the whole point. Practising them on somebody else’s question list will not help unless the list makes you speak; practising them on a question with a worked answer beside it lets you compare your route to a route that works.

Should You Rehearse Answers Before 7 December?

Rehearsing answers, no. Rehearsing method, yes — and the distinction is not pedantry.

Cambridge frames the interview as “a friendly conversation” and tells applicants they can answer “in your own way” without saying what they think interviewers want to hear. Trinity states plainly that “The interviews are academically focused, and we don’t set traps or ask trick questions to catch you out.” A memorised answer collides with both: it is audible, it is brittle the moment the follow-up shifts the ground, and it substitutes recall for the thinking that is actually being assessed.

What does transfer is fluency. Being used to talking through a half-formed idea, being comfortable saying “I am not sure, but here is what I would try”, being unbothered by a pause. Cambridge’s own preparation advice suggests a practice interview with a teacher or someone who does not know you well, precisely so you get used to expressing ideas under mild pressure rather than to a friendly audience.

Give yourself the right context, too. Across all subjects Cambridge receives “about six applications per place”, and the interview is one instrument among several rather than a single pass-or-fail gate. Our overview of Oxbridge interview preparation sets out how the pieces fit together for December.

Where to Go Next, by Subject

The subject pages linked in the table above each carry questions of the right shape with the reasoning worked through, which is the format Cambridge’s own descriptions imply you should be practising on. Start with your own subject rather than with a general list.

If you want the same material offline and in one file, the Oxbridge interview question packs are 30 packs across 17 subjects at £180 each. Each pack is ten questions, each with prompts for when you stall and a full worked answer beneath. Nine subjects have a free sample — biology, chemistry, engineering, geography, german, history, maths, physics and vet medicine — and reading one before you decide anything is the sensible first move, because it is the same format as the pack it comes from.

Whatever you use, use it out loud. Cambridge has told you what it is measuring, and the failure our specialist tutors see is never the candidate who did not know enough. It is the candidate who knew enough and worked it out silently.
