Pre-CAS Interview in the UK: Why Universities Check Harder and How to Prepare
TL;DR: A pre-CAS interview is a check your UK university runs after your offer and before it issues your Confirmation of Acceptance for Studies (CAS). Many universities now use a recorded, automated video interview, often called the "AI interview", with around 15 to 17 questions and 60 to 90 seconds per answer. It tests whether you are a genuine student and whether your funds meet visa rules. Prepare your study reasons, study gaps, numbers and timing before the university asks.
Many Sri Lankan applicants think the hard part ends with the offer letter. Then an email arrives with a link to a recorded interview. There is no person on the other side. A question appears on screen, a timer starts, and you have about a minute to answer. It can feel like a second admission test. With the right preparation, it is very manageable.
What the pre-CAS "AI interview" looks like
The pre-CAS interview normally comes after you receive your offer and before the CAS is issued. More and more universities now run it as a recorded video interview on an online platform, rather than a live call. Students often call it the AI interview, because there is no interviewer. You read each question on screen and record your answer against a timer.
In our admissions work, these recorded interviews usually run to around 15 to 17 questions, with 60 to 90 seconds to answer each one. Some universities hold the interview live instead, through a Teams meeting. Either way, the interview also tests your spoken English.
The timer is what catches most students out. Sixty seconds is short. If you pause too long, you run out of time before you reach the point. If you finish in 20 seconds, the answer sounds thin.
Pre-CAS interview questions you should expect
The wording changes from one university to the next, but the topics are consistent. Based on published university guidance and the interviews our students sit, expect questions in these areas. Most students freeze on the money questions, so know every number in your file without looking it up.
Question area | Typical questions | What a strong answer includes |
|---|---|---|
Why the UK | Why study in the UK? Why not study this course in Sri Lanka? | A specific reason tied to your goal, such as the course structure or a specialism, not "good education" |
Why this university and course | Why this university? Why this course, and which modules interest you? | Two or three named modules and what drew you to this university |
Location | What do you know about the city or town where the university is? | Something real about the campus, transport or local industry |
Link to past study | How is this course related to your previous studies or work? Why are you changing field? | One clear line from your degree or job to this course |
Working in the UK | Do you plan to work while you study? | Study comes first, and you know the working-hours limit on the GOV.UK Student visa page |
Plans after the course | What will you do after you complete your master's? | A named role and type of employer, not "a good job" |
Challenges | What challenges do you expect in the UK, and how will you handle them? | A calm, practical plan, not a rehearsed line |
Funds | What is your tuition fee? Did you get a scholarship? How much deposit have you paid? How much are you showing for living costs, and who is funding you? | Exact fee, scholarship, deposit paid, balance, show money figure and sponsor |
Managing expenses | How will you balance your monthly expenses? | A rough monthly budget for rent, food and transport |
Accommodation | Where will you stay? | Where you plan to stay and roughly what it costs |
Random questions | Wildcard questions picked at random from a set list | A short, honest answer in your own words |
The financial check is often the real test
Many universities now review bank statements before the CAS, not just at the visa stage. The normal rule is that the required funds must be held for at least 28 consecutive days, and the end of that 28-day period must be within 31 days of your visa application. The money must be in your own account or your parent's or legal guardian's account. If it is a parent's account, you also need their consent letter and your birth certificate.
The amount you must show is also changing. From 30 November 2026, the Home Office is raising the Student visa maintenance figure to match updated student maintenance loan levels. We explain the new figures in our article on the UK student visa maintenance funds increase.
How to prepare for the pre-CAS interview
Write your own answers first. A one-page note on why the UK, why this university, why this course and what comes after keeps your story consistent.
Know your numbers. Tuition fee, scholarship, deposit paid, balance due, the living cost figure and who is funding you.
Practise against a timer. Record yourself answering in 60 seconds. Aim to make your main point in the first 20 seconds.
Match your documents to your words. If you say your father is funding you, his statement and consent letter should be ready.
Set up your space. Test your camera, microphone and connection, and sit somewhere quiet with good light.
Answer in your own words. Do not read from a script or use AI tools during the interview. Universities watch for both.
Be honest about gaps and refusals. A clear explanation is far better than an answer that later conflicts with a record.
The Home Office runs its own credibility interview later in some cases. Our UK student visa interview guide covers that stage.
How Prosper prepares students for the pre-CAS interview
At Prosper, preparation starts long before the interview link arrives:
Statement of purpose first. We fine-tune each student's SOP so it tells one clear story. Interview answers come from the same story, so they match what the university has already read.
A walk-through of every question. We go through each question area and build the answers from the student's own SOP and documents.
Answers in key points. Students prepare a few short points per answer, not a memorised paragraph, so they stay focused and sound natural.
Timing practice. Every answer is practiced against a timer: main point first, one or two details, finished within 60 to 90 seconds.
Two or more mock interviews. Run in the same environment as the real AI interview, with questions on screen, a timer and answers recorded on camera.
Feedback between mocks. Each mock shows where answers are weak or run over time, and the next one checks the fix.
By the time the real interview arrives, the format is already familiar.
Frequently asked questions
What is a pre-CAS interview? A short interview run by your UK university after your offer and before it issues your CAS, to check that you are a genuine student and meet the visa requirements.
What is the pre-CAS AI interview? It is a recorded, automated video interview. Questions appear on screen and you record each answer against a timer. There is no live interviewer, and university staff review the recordings.
How many questions are in a pre-CAS interview? It varies by university. In our experience, recorded interviews usually have around 15 to 17 questions.
How long do I get to answer each question? Usually 60 to 90 seconds per question.
Can a UK university refuse to issue a CAS after an offer? Yes. Bradford and Dundee both state they reserve the right to refuse a CAS if the interview suggests the student is not genuine or the risk of visa refusal is too high.
Can I retake the pre-CAS interview? It depends on the university. Some give only one attempt, so prepare before you start.
Are my parents' bank statements accepted? Often yes, with a letter of consent. Rules vary by university, so check the list your university sends.

PS: A pre-CAS interview rewards preparation that happens weeks before the link arrives. At Prosper, we build your answers from your statement of purpose and run two or more timed mock interviews before the real one. If you want your course choice, funds and answers checked before the university asks, check your eligibility with Prosper. We submit applications only when we are at least 95% confident the student will receive an offer.
