Every published Oxford and Cambridge interview length in one table, plus the hour at which each subject learns whether a second college is calling
Book a Free ConsultationCambridge publishes a number: most applicants have “1 or 2 interviews lasting a total of 35 minutes to an hour”. Oxford publishes none centrally — its colleges do, and they disagree. St Hugh’s says 20-30 minutes; Lincoln says 25 to 40. Below is every published figure we could find at source, how the interviews sit across December, and what happens in the minutes either side.
Half an hour is not long to show how you think. Our subject packs (£180 each) set the reasoning out in full so you can practise to the clock, written by specialist tutors. Nine subjects have a free sample.
See the packs and free samples Or book a free consultationThe two universities answer this question in completely different places, and that is why the internet gives you three different answers to it. Cambridge answers centrally. Its undergraduate admissions site states, under a heading about how many interviews you will have, that “Most applicants will have 1 or 2 interviews lasting a total of 35 minutes to an hour. Some may have 3 or 4 interviews, depending on subject and College.” That is a total, not a per-interview figure, and the distinction matters enormously to how you rehearse.
Oxford does not do this. We read Oxford’s main applicant guide to interviews and its dedicated interview FAQs page in full, and neither states how long an interview lasts. They cover who interviews you, where you sit, what software you need, what happens if you fall ill, what happens if your connection drops, and what you may and may not do during the call. On duration they are silent. The figure exists, but it is published by individual colleges, on individual college websites, and the colleges do not all say the same thing.
That silence is not an oversight so much as an accurate reflection of how Oxford admissions work. Oxford tells applicants that “You are quite likely to have more than one interview. You might also be interviewed by more than one college.” If your December could contain an initial interview at one college and an additional interview at another, arranged after the first has happened, then a single university-wide minute figure would be misleading rather than helpful. Cambridge, which assesses you through one College unless you are pooled, can publish a total honestly.
The practical consequence for you is simple: for Cambridge, use the university figure. For Oxford, the only figure that applies to you is the one your interviewing college publishes — and you may not know which college that is until the invitation arrives.
Every figure in this table was read directly from the page named in the final column. Where a source publishes a range, the range is reproduced as a range. Nothing here is averaged, rounded or combined.
| Source | What the figure covers | Published length | Where it is published |
|---|---|---|---|
| University of Cambridge (central) | Total across all your interviews | 35 minutes to an hour, for most applicants | Undergraduate admissions, Interviews |
| University of Oxford (central) | — | No duration published | Applicant guide and interview FAQs |
| St Hugh’s College, Oxford | One interview | Normally 20-30 minutes long | The Application Process |
| Lincoln College, Oxford | One interview | Between 25 and 40 minutes; the majority around half an hour | Preparing for Interview |
| Trinity College, Cambridge | Log-in time before a remote interview | 10 minutes in advance | Interviews |
Read the two Oxford college rows together and you have the honest answer to the headline question at Oxford: each college publishes its own band, and the college interviewing you is the only body that has told anyone which band applies to you. Lincoln adds the detail that makes the range usable, saying that of its interviews “the majority will be around half an hour”. St Hugh’s adds who is in the room: its interviews “are usually conducted by two or more tutors at a time”, which matches what Oxford says centrally.
Note what the Cambridge row does not say. It does not say that one Cambridge interview lasts 35 minutes to an hour. It says that is the total across however many you have. If you have two, each one is shorter than that band. Sources that present that band as a per-interview figure for Cambridge are reading a total as a unit figure, and the mistake is easy to make because the sentence sits under a heading about numbers rather than about length.
Knowing the length only helps if you have used it. Our specialist tutors run 1-to-1 mock interviews to the published durations, in the subject you are applying for, so the pacing is familiar before December.
Book a Free Consultation Message us on WhatsAppCambridge is explicit and reassuring in the same breath: “The number of interviews you have does not relate to how strong your application is. Most applicants will have 1 or 2 interviews… Some may have 3 or 4 interviews, depending on subject and College.” If you are placed in the winter pool you may be invited to an additional interview at a different College in January, which is a separate event rather than a repeat of December.
Oxford does not give a number, but it does publish something more revealing. Its applicant guide states that “Oxford typically offers around 20,000 online interviews to approximately 10,000 shortlisted candidates.” It gives the shortlisting context in the same place: “Oxford typically receives over 23,000 applications for around 3,300 places every year and shortlists approximately 10,000 candidates.” The university’s own summary of what that volume means for you is the sentence quoted above — you are quite likely to have more than one interview, possibly at more than one college.
Oxford also distinguishes two ways this happens, and the difference decides how much of December you have to hold clear. In some subjects, it says, “you will be invited to more than one interview and/or at more than one college before your interviews start.” In others, “you might have ‘initial’ interviews at your first college and then be invited to an ‘additional’ interview at another college after these have taken place.” If your subject is in the first group, your December is fixed the day the invitation lands. If it is in the second, part of it stays provisional until a deadline that Oxford publishes to the hour. That is the subject of the next two sections.
For the tightest subjects the shortlisting itself is severe before any of this begins. Oxford’s Medicine course page states that “only around 425 applicants are shortlisted for interview each year”. Our Oxbridge Medicine interview guide covers what that shortlist is looking for.
Oxford publishes a subject-by-subject interview timetable. At the time of writing it says the 2026 version “will be available as soon as possible” and offers the previous year’s in the meantime: “In the meantime, you may find it useful to refer to the 2025 subject-specific timetable below.” Everything in this section and the next is therefore that 2025 reference timetable, quoted as Oxford presents it. It tells you the shape of a December, not this year’s dates. For what is confirmed versus projected for this cycle, see our Oxbridge interview dates guide.
The shape is the useful part, because it is not what most candidates assume. Two subjects can both be “interviewed in December” and have completely different Decembers. Biology, in the reference timetable, is compact: “Each candidate will have interviews at two colleges between Monday 8 and Friday 12 December.” Medicine is tighter still: “Each shortlisted candidate will be interviewed by two colleges, with the interviews being either on Monday 15 or on Tuesday 16 December.” Two colleges, one or two days, done.
History sits at the other extreme. Its first college interviews run “on Monday 8, Tuesday 9, Wednesday 10, Thursday 11 and Friday 12 December”, and its second college interviews run “on Monday 15, Tuesday 16, Wednesday 17 and Thursday 18 December”. A History candidate can be interviewed at the very start of one week and the very end of the next, with a weekend and several working days in between during which nothing at all happens. Archaeology and Anthropology stretches to a third college: interviews at a first college on Monday 15, a second on Monday 15 or Tuesday 16, and “Third college interviews will take place on Thursday 18 December.”
This is why “keep December free” is not a platitude. Cambridge states its own period plainly — a main interview period of 7 December to 18 December 2026, with winter pool interviews around mid to late January 2027 — and adds that it cannot reschedule except in exceptional circumstances. Oxford says the same in different words: interviews cannot be rearranged, because of the logistics of that 20,000 figure.
This is the part of the Oxford process that nobody writes down, and it is the most useful thing on this page. Where a subject has additional interviews, Oxford’s timetable does not merely say they might happen. It publishes the hour by which you will be told whether they are happening to you. The wait is finite and its end is a published time of day.
In the 2025 reference timetable, the deadline varies by subject, and the variation is wide:
Two things follow. First, if your subject appears on a list like this, the silence after your first interview has a published expiry, and refreshing your inbox before it is wasted effort. Second, the gap between the notification and the interview itself can be very short: a Computer Science candidate can learn at 6pm on a Wednesday about an interview the following day. Oxford underwrites this with a floor rather than a promise of comfort — “We aim to give everyone a minimum of 24 hours’ notice of these additional interviews.”
Plan on that basis. The realistic reading of a subject with a late notification deadline is that your preparation has to be finished before your first interview, because there may be no usable window between the second invitation and the second interview.
A second college can call with a day's notice. Our specialist tutors keep you in practice across the whole December fortnight, in your own subject.

Oxford describes the mechanics precisely: “For each interview, you’ll be sent a separate calendar invitation containing a link that will take you to the Microsoft Teams virtual interview lobby. You’ll then be accepted into the call and your interview will begin.” A separate invitation per interview is worth noting on its own — a second interview is a second email, and Oxford advises checking your junk folder if one does not arrive.
Colleges add their own front end to that lobby. Trinity College, Cambridge tells remote candidates: “We strongly encourage you to log in for your interview(s) 10 minutes in advance. You will be met there by some of our student ambassadors, who will make sure your technology is working well. They will pass you through to the interviewers at the appropriate time.” So for some candidates the first face on screen is a current student doing a sound check, not an academic.
Before that again, there may be reading. Oxford tells candidates to make sure they have done any pre-reading sent to them, and that “normally this will be emailed to you the day before your interview”. Its FAQs add a condition that catches people out: “You must not research online any materials shared with you as part of a pre-interview task unless explicitly permitted to do so by the interviewers.” The passage is a set text to think about, not a research prompt. Our guide to Oxford’s online interview setup covers the equipment side of the same ten minutes.
My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
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.
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.
Nothing below is invented. Each stage is something Oxford or a college states publicly; the only contribution here is putting them in the order they occur.
Held against a 20-30 minute interview at St Hugh’s, stages three to six are where almost all of the time goes, and stages one, two and seven consume some of it without testing anything. That is the argument for rehearsing the middle rather than the opening.
Candidates read length as a verdict. Both universities say, in their own words, that it is not one. Cambridge’s statement is the blunter of the two: “The number of interviews you have does not relate to how strong your application is.” It says the same about scheduling: “The timing of your interview does not reflect your perceived strength as a candidate.”
Oxford makes the equivalent point about the interview itself, telling candidates that interviewers “are not trying to make you feel ignorant or catch you out, but to stretch you in order to assess your potential”, and that being shortlisted at all is significant given that it typically shortlists approximately 10,000 candidates from over 23,000 applications for around 3,300 places. A conversation that ends earlier than the one your friend describes has most likely reached the end of the material those particular tutors planned to use.
What the outcome actually turns on is set out separately by the faculties and colleges. Our guide to what Oxbridge interviewers actually mark works through the published criteria. Oxford’s own decisions arrive on a fixed date: its 2027-entry timeline states you will “Find out if you have an offer on 12 January 2027.”
A short interview is not a bad sign, but an unrehearsed one is a wasted half hour. Our specialist tutors run the conversation itself, and the subject packs (£180 each) set the reasoning out in writing first.
Browse the subject packs Or book a free consultationIf the whole assessment at Cambridge can be a total of 35 minutes to an hour, and an Oxford college publishes a single interview as 20-30 minutes, then the scarce resource is not knowledge. It is the speed with which you can turn a question you have never seen into audible reasoning. Ten minutes of silence is a large fraction of a half-hour interview.
Three things follow, and all of them are about pace rather than content. Rehearse being interrupted, because a tutor suggesting another approach is a normal event and it costs time to recover from if it is a surprise. Rehearse the first thirty seconds of an answer, because that is the part you can actually plan. And rehearse in the format your college uses — our guide to running a mock interview at home sets out how, and our Cambridge interview format guide tells you which format your College uses.
You also need something real to practise against. Our Oxbridge interview question packs exist for that: 30 packs across 17 subjects, £180 each, with the reasoning written out in full rather than summarised, and free samples in nine of the subjects. Our specialist tutors run the conversation itself, in the format and to the length your interviewers will use. You can check the published length for your own college on the Cambridge interviews page or, for Oxford, on the college website named in your invitation.
There is no single Oxbridge figure, because the two universities publish at different levels. Cambridge publishes a total centrally: most applicants have “1 or 2 interviews lasting a total of 35 minutes to an hour”, and some have 3 or 4 depending on subject and College. Oxford publishes no duration at all on its central applicant pages; its colleges publish their own. St Hugh’s College states its interviews are “normally 20-30 minutes long”, while Lincoln College states they “typically last between 25 and 40 minutes and the majority will be around half an hour”. So the honest answer depends on which university, and at Oxford on which college is interviewing you.
In total. Cambridge’s sentence sits under a heading about how many interviews you will have, and reads: “Most applicants will have 1 or 2 interviews lasting a total of 35 minutes to an hour.” The band therefore covers everything you sit, not each conversation separately. If you have two interviews, each one is shorter than that band. This is the single most common misreading of the Cambridge figure, and it matters because it changes what you rehearse: a shorter conversation leaves less room to recover from a slow start.
Not centrally. We read Oxford’s main applicant guide to interviews and its dedicated interview FAQs page in full. Between them they cover who interviews you, where you should sit, what software you need, what happens if you are ill, what happens if your connection drops, and what you may and may not do during the call. Neither states a duration. Oxford does publish that “Normally you will be interviewed by two tutors, occasionally more”. For a length, the only figure that applies to you is the one published by the college that has invited you.
Cambridge says most applicants have 1 or 2 interviews, and some have 3 or 4 depending on subject and College. It adds plainly that “The number of interviews you have does not relate to how strong your application is.” Oxford gives no per-candidate number but states that “You are quite likely to have more than one interview” and that “You might also be interviewed by more than one college.” It also publishes the volume behind that: Oxford “typically offers around 20,000 online interviews to approximately 10,000 shortlisted candidates”.
Much further than most candidates expect, and it depends entirely on your subject. In Oxford’s published reference timetable, Biology candidates have “interviews at two colleges between Monday 8 and Friday 12 December”, and Medicine candidates are interviewed by two colleges “either on Monday 15 or on Tuesday 16 December”. History runs across both weeks: first college interviews on Monday 8 to Friday 12 December, second college interviews on Monday 15 to Thursday 18 December. That is why both universities tell applicants to keep the whole period free rather than a single day.
By making the length familiar before it matters. Our specialist tutors run 1-to-1 mock interviews to the durations the universities publish, in the subject you are applying for, so the pacing is rehearsed rather than discovered on the day. The subject packs set the reasoning out in writing first, with the answers worked through in full rather than model answers to memorise, at £180 each as a one-off; there are 30 packs in the catalogue. Nine subjects have a free sample, so you can judge the material before deciding anything. 91% of our students achieve their desired grades.
Free samples in nine subjects show you the format, the full expert packs are £180 each with the reasoning written out in full, and 1-to-1 mock interviews run to the length your interviewers will use.
