TL;DR: The interview is a short academic conversation with people who may become your tutors. Cambridge runs its main round 7 to 18 December 2026, most applicants getting one or two interviews totalling 35 minutes to an hour. Oxford interviews online over Microsoft Teams, with its Maths department putting each at about 25 minutes. Both publish free preparation guidance and both discourage paid coaching.
Getting an interview does not mean you are nearly there.
Oxford is blunt about the scale. It typically offers around 20,000 online interviews to roughly 10,000 shortlisted candidates. Cambridge puts it just as plainly: it invites many applicants to interview, not everyone interviewed will be offered a place, but everyone who is made an offer will have been interviewed.
So the interview is the stage that decides.
It is also the stage most applicants misunderstand, which makes it the easiest one to get better at.
What actually happens in an Oxbridge interview?
Not a panel firing trivia at you.
Oxford explains why it interviews at all: a good deal of its teaching happens in small classes or tutorials, and your interviewers, who may be your future tutors, are assessing your ability to study, think and learn that way. Oxford states that decisions are not based on your manners, appearance or background, but on your ability to think independently and engage with new ideas beyond your school syllabus.
Cambridge says you are likely to be asked to discuss topics with two or three interviewers and to apply your knowledge to new situations, materials, problems or scenarios. You may also be asked why you chose your course, about developments in your subject, and about recent topics from school or from your personal statement.
Science and maths applicants may be asked to share their workings on a problem. You may also be sent material to read beforehand and asked to discuss it. Some applicants sit a broader general academic interview, sometimes run by academics outside their subject. Medicine and Veterinary Medicine applicants get asked about the vocational side of the course.

What do the questions actually look like?
Oxford publishes real sample questions, attributed to the tutors who ask them, with their reasoning: https://www.ox.ac.uk/admissions/undergraduate/applying/guide-for-applicants/interviews/sample_questions
Read a few and the pattern becomes obvious.
Kathryn Scott at Christ Church asks Biochemistry candidates whether a given compound would be more soluble in octanol or water, showing them a structure with functional groups they would know from A-Level or IB. Her explanation is the clearest statement of what these interviews are for. She does not expect the student to know the answer straight away, and getting the correct answer is not important. What is useful to her is seeing how the candidate applies chemical knowledge to a problem they have not considered before, how they justify their conclusions, and whether they can hold alternative possibilities in mind. If a student cannot find a starting point, she prompts them.
Emma Smith at Hertford opens English interviews by asking about a literary work from the candidate’s own personal statement, then adds a warning in brackets: so be honest on your personal statement. She wants to move the discussion from what a text is about to how it is written.
Lucinda Rumsey at Mansfield asks about JK Rowling writing for adults after Harry Potter, and explains her reasoning. She is careful to judge candidates on what they know rather than what they do not, and starting with Harry Potter means everyone has a point of recognition.
None of these questions has a right answer you could revise for.
How many interviews will I have, and how long are they?
More than one, at both.
| Oxford | Cambridge | |
|---|---|---|
| Number | Quite likely more than one, possibly at more than one college | Most have 1 or 2; some have 3 or 4 by subject and College |
| Length | Maths puts each at about 25 minutes | 35 minutes to an hour in total |
| Dates | December 2026 | 7 to 18 December 2026 |
| Format | Online, Microsoft Teams | Online or in person, set by College |
| Decision | 12 January 2027 via UCAS | January |
Oxford distinguishes between initial and additional interviews. In some subjects you are invited to several interviews, or to more than one college, before the round starts. In others you sit initial interviews at your first college and are then invited to an additional interview at another college afterwards. Oxford aims to give at least 24 hours’ notice of those additional ones.
Oxford Maths spells out its own pattern: generally one or two interviews at your first-choice college, plus at least one more elsewhere: https://www.maths.ox.ac.uk/study-here/undergraduate-study/interviews
Cambridge is explicit that the number of interviews you have does not relate to how strong your application is. Neither does the timing of your invitation.
Will my interview be online or in person?
At Oxford, online, over Microsoft Teams. Oxford sorts the technology into three tiers. Tier 1 is video conferencing only, and most courses sit there. Tier 2 adds an interactive virtual whiteboard. Tier 3 adds natural handwriting capture through a stylus. Oxford publishes an instructional video for each tier: https://www.ox.ac.uk/admissions/undergraduate/applying/guide-for-applicants/interviews
At Cambridge it depends on which College is assessing you, and Cambridge publishes a College-by-College table for 2027 entry.
Of the 29 Colleges listed, 14 interview everyone online, including Christ’s, Downing, Girton, Newnham, Queens’ and St John’s. Only four interview everyone in person: Churchill, Emmanuel, King’s and Selwyn. The other eleven vary. Peterhouse, Robinson, Sidney Sussex and Trinity Hall interview UK applicants in person and overseas applicants online. Trinity interviews UK applicants in person but lets those based outside the UK choose. Corpus Christi, Gonville and Caius, Pembroke and Homerton each set their own arrangement again.
Online is the more likely outcome by some distance. You usually cannot request a format, though a College may offer an alternative at its discretion in exceptional circumstances such as a disability or a declined visa.
What am I agreeing to when I accept the invitation?
This is the part nobody mentions, and it is binding.
If Oxford shortlists you, accepting the invitation means accepting an interviewees’ code of conduct. You agree not to share the content of your interviews in any form, which covers discussing them verbally with other candidates or teachers at your own school or any other, and covers passing on any documents or images shared before or during the interview.
You agree not to research online any material shared with you as part of a pre-interview task, unless the interviewers explicitly say you may.
And you agree not to use assistive technology, including artificial intelligence and automatic transcription tools, beyond what your subject requires, unless explicitly permitted.
Read those before you accept. The first one in particular is easy to breach without meaning to, by comparing notes with a friend who interviews the day after you.
Why do they interview at all?
Because a predicted grade and a polished personal statement say very little about whether you can hold up in a tutorial.
Cambridge lists what it is assessing: your understanding of your chosen subject area, your readiness to study at a high academic level, whether you will thrive in the Cambridge learning environment, your ability to think critically and independently, your curiosity and openness to new ideas, and your enthusiasm for your subject.
Every item on that list is about how you think, not what you have stored.
How do I prepare without over-rehearsing?
Both universities have published statements discouraging paid interview coaching.
Cambridge has a section headed “Beware of commercial tutoring services.” It states these services are not endorsed by the University, that they have no access to exclusive information, and that all official guidance is free on its website.
Oxford’s Mathematical Institute goes further: it very much does not want applicants to feel they need special training for its admissions.
What both recommend instead costs nothing.
Cambridge asks you to reread your personal statement and any written work you submitted, explore your subject beyond school through books, videos and podcasts, practise talking about your subject with friends, family or teachers, and sit a practice interview. Its advice on who should run that practice is sharper than it first looks: ideally a teacher, or someone who does not know you well, so you are genuinely practising explaining yourself rather than talking to someone who already follows your shorthand. Failing that, ask yourself questions for half an hour: https://www.undergraduate.study.cam.ac.uk/apply/after/interview-preparation
For arts, humanities and social sciences, Cambridge suggests reading beyond your set texts and thinking critically about what you read. For maths and science, practise problem solving and think about how you would show or explain your working.
Oxford’s checklist runs eight steps, and step seven is the substantive one. Reread your personal statement and submitted written work. Think about the answers you gave in any admissions test, without worrying if you cannot remember them in detail. Remind yourself why you chose the subject.
Oxford Maths recommends arranging a practice interview with a teacher and working through a past admissions test question in front of them, or explaining A-Level Maths concepts to friends and family who are not mathematical. Doing that gets you used to explaining your thoughts out loud and consolidates your own understanding at the same time.
That page also carries the single most useful sentence on either university’s website. Oxford’s mathematicians point out that they are not mind-readers, and that if you do not say anything, they cannot tell what you are thinking.
That is the whole skill. Narrating your reasoning while it is still unfinished.
What should I remember on the day?
Both publish reassurances that contradict what nervous applicants assume.
Oxford says wear clothes you feel comfortable in, because you will not be judged on what you wear. Make sure your head is not cut off by your camera and that you can look directly at the screen. Think of it as a conversation about your favourite subject with people who share your interest and know a great deal about it. Oxford adds that you may well find you learn something.
If you do not know an answer immediately, work your way through it aloud. Oxford’s reason for this is worth memorising: doing so lets tutors see how you think, which means your final answer is only part of what they find out.
Listen carefully and ask for a question to be repeated if you need to. Keep paper and a pen. Have your personal statement or written work to hand if you want, but do not let it distract you from the questions.
Cambridge adds that you can be yourself, that it is a friendly conversation, that you can ask interviewers to explain something you do not understand, and that you can answer in your own way because you do not need to say what you think they want to hear.
For an online interview, pick a quiet space, charge your device fully, test your webcam, microphone and connection, and keep the College’s phone number to hand. Science and maths applicants told to expect a shared whiteboard should practise with a stylus and tablet first. Some Colleges run a tech check session.
One thing that genuinely catches people out. If you fall ill or something goes wrong on the day, contact your College admissions office before your interview. Cambridge states that if you do not tell them, they will take it that you are fit and ready, and that anything reported after the interview will not usually be taken into account.
Tell them first. Not afterwards.
Separately, if the technology fails during an Oxford interview, you will be offered another time.
What can go wrong?
Two things, mostly.
Silence. If you do not think out loud, there is nothing to assess and nothing for the interviewer to help you with. A wrong first attempt spoken aloud gives them something to work with.
Reading a hint as a failure. When a tutor redirects you, that is the format working. Kathryn Scott prompts candidates who cannot find a starting point, and she designed the question that way. Being corrected is not the same as being marked down.
What about dates and rescheduling?
Keep December free.
Cambridge cannot reschedule except in exceptional circumstances, which may include hospital appointments, illness, religious observance or exams. If you do not attend, you will not be considered for a place.
Oxford points to logistics. Running 20,000 interviews means it is not possible to rearrange the time of yours.
Cambridge sends most invitations in November, some in early December. Oxford usually writes between mid-November and early December, from the college you applied to or were allocated, and warns you may only get a week’s notice.
You might also be interviewed by a college you did not apply to. At Oxford this is the reallocation process, which moves applicants around so everyone interviewed has a similar chance of an offer. At Cambridge, the winter pool may bring an additional interview at a different College in mid to late January 2027.
Neither is a bad sign.

Frequently Asked Questions
How long does an Oxford or Cambridge interview last?
At Cambridge, most applicants have one or two interviews lasting 35 minutes to an hour in total, and some have three or four depending on subject and College. Oxford varies by course; its Mathematical Institute puts each at about 25 minutes.
Are the interviews online or in person?
Oxford’s are online over Microsoft Teams. Cambridge’s depend on the College. Fourteen of its 29 Colleges interview everyone online, four interview everyone in person, and eleven vary, usually by whether you are UK-based.
Can I use AI to help me prepare or during the interview?
Oxford’s code of conduct says you agree not to use assistive technology, including artificial intelligence and automatic transcription tools, beyond what your subject requires, unless the interviewers explicitly permit it. You also agree not to research online any material given to you as a pre-interview task.
Can I talk to friends about my interview afterwards?
Not at Oxford. Accepting the invitation means agreeing not to share interview content in any form, including verbally with candidates or teachers at your own or any other school.
When will I find out if I have been shortlisted?
Cambridge sends most invitations in November, some in early December. Oxford usually writes between mid-November and early December and says you may only get a week’s notice. Additional interviews at other Oxford colleges come with a minimum of 24 hours’ notice.
What if I am ill on the day of my interview?
Contact your College admissions office before the interview starts. Cambridge states that if you do not, they will assume you are fit and ready, and that circumstances reported afterwards will not usually be taken into account.
What if my internet fails mid-interview?
Oxford states that if there are technical issues during your interview, you will be offered another time.
Should I pay for interview coaching?
Both universities say no. Cambridge states commercial tutoring services are not endorsed and hold no exclusive information. Oxford’s Mathematical Institute says it does not want applicants to feel they need special training.
When do I hear the outcome?
Oxford tells shortlisted candidates for 2027 entry on 12 January 2027 via UCAS, with colleges following up later the same day. Cambridge releases outcomes in January for October applicants.
Conclusion
Most people prepare in the wrong direction. They spend months building a library of answers, then walk into an interview whose entire design is to hand them something the library does not cover.
Kathryn Scott says it herself. Getting the correct answer is not the point. What she is watching is how you handle a problem you have never seen.
You build that by reading widely in your subject, explaining ideas to people who do not already understand them, and getting comfortable being visibly uncertain in front of someone who knows more than you. Both universities recommend exactly this, and neither charges for it.
Working on original research is one of the more demanding ways to build the habit, because you spend months defending your own reasoning to a specialist who keeps pushing back. That is what OCAR pairs students with Oxbridge and Ivy League mentors to do: https://oxford-research.uk.com/what-is-ocar
