What to Expect from the Cardiothoracic Surgery ST1 Interview

Cardiothoracic Surgery ST1 is one of the most competitive entry points in UK specialty training. NHS England’s 2025 figures record 737 applications for 10 posts, a ratio of 73.7:1, up sharply from around 45:1 in 2024. NHS England Wessex, the national lead recruiter, has indicated up to 12 ST1 posts for August 2026 entry across England, Scotland, Wales and Northern Ireland. With ST4 Thoracic recruitment closing after 2026, ST1 becomes the sole entry route from 2027, so pressure on this interview is unlikely to ease.

The interview is delivered entirely online via Qpercom Recruit on 2-3 February 2026. There is no in-person option, and invited applicants are asked to keep both days free in case of technical issues. Total assessment time is approximately 50 minutes, split across two stations, each scored by a panel; candidates typically report around three assessors, often Training Programme Directors and SAC members, though the applicant guide does not confirm panel composition. Lay Representatives may observe with camera off and microphone muted; they do not score. The interview score is combined with the carried-over self-assessment score to produce the final ranking, alongside your Oriel preferences. Station content may change between applications opening and the interview itself, with full detail provided to invited applicants.

Structured Questions Station

Approximately 25 minutes, five questions. Based on the person specification, this station is expected to test clinical judgement and structured reasoning at ST1 level: recognition and initial management of the acutely unwell patient, ABCDE-style assessment, prioritisation, escalation and safe decision-making, together with portfolio-style content, including commitment to cardiothoracic surgery specifically. Panel members score against person-specification domains rather than expecting advanced operative knowledge.

Communication Skills Station

Approximately 25 minutes, three questions. This station assesses how you handle communication challenges relevant to surgical practice: interactions with patients and families, working within multidisciplinary teams, and managing difficult professional situations. Assessors are looking for clarity, empathy, structure and awareness of Good Medical Practice, not a rehearsed script.

What the Panel Is Looking For

Across both stations, the panel is scoring against the 2026 person specification and ISCP cardiothoracic curriculum domains. That means clinical judgement and patient safety, prioritisation under pressure, professionalism and probity, teamwork and leadership, and communication that is clear and patient-centred. Commitment to specialty runs through the whole interview: evidence of taster experience, theatre exposure, SCTS engagement, audit, research and a realistic understanding of the training pathway. Given the ratio, marginal differences in delivery decide outcomes, so structured, specific answers backed by your own examples score materially better than generic ones.

The Medibuddy 2026 Cardiothoracic Surgery ST1 Interview Question Bank

We’ve built the bank around the real shape of the 2026 Cardiothoracic Surgery ST1 interview: the structured stations, the portfolio probing, the clinical and management scenarios, and the ethics and professionalism reasoning framed against GMC Good Medical Practice and RCS Good Surgical Practice. It covers every station comprehensively, with model answers, examiner-style probes and marking notes written by high-scoring cardiothoracic trainees and registrars who recently sat the interview themselves. We refresh the content each year using feedback from that year’s candidates, so what you practise reflects what interviewers are actually asking.

What’s Included in the Cardiothoracic Surgery ST1 Interview Question Bank

How to Prepare for the Cardiothoracic Surgery ST1 Interview

Preparation for this interview needs to be shaped by its actual structure: two online stations totalling roughly 50 minutes on Qpercom Recruit, tested against a national field of applicants for a handful of posts. Generic surgical interview prep aimed at Core Surgical Training will only get you part of the way. Below is how we recommend approaching it.

Understand the format before you start practising

Start by internalising exactly what you’ll face on 2-3 February 2026. The interview is delivered virtually via Qpercom Recruit and consists of a Structured Questions station (five questions in around 25 minutes) and a Communication Skills station (three questions in around 25 minutes). Questions are delivered in quick succession within each station, so there’s very little time to plan an answer once a question lands. The Wessex applicant guide is explicit that content areas may shift between applications opening and the interview itself, so build flexible frameworks rather than rehearsing fixed scripts.

Focus on knowledge and delivery equally

Cardiothoracic-specific knowledge decides whether you have anything to say; delivery decides whether the panel scores it. Both stations reward structured, panel-facing answers: a clean opening sentence that answers the question directly, a signposted middle, and a definite close. Content covers the person specification, so expect clinical reasoning under time pressure, ethical and professional scenarios, motivation and commitment to specialty, and communication tasks. Pair every knowledge topic you revise with a spoken run-through so the two develop together.

Build preparation around each station

For the Structured Questions station, drill answers to clinical scenarios relevant to cardiothoracic practice. Based on the person specification and candidate accounts, typical topics include acute chest pain, post-operative complications and the deteriorating patient, alongside ethical and professionalism dilemmas and questions probing your commitment to the specialty and portfolio-style content. Five questions in 25 minutes means each answer sits at roughly four to five minutes. Practise landing your point inside that window.

For the Communication Skills station, work on role-played tasks: breaking bad news, consenting for a cardiothoracic procedure at a level appropriate to ST1, dealing with an angry relative or colleague, and escalating concerns. Three questions in 25 minutes gives you more room per station, but panels will mark you down for medical jargon, poor empathy signalling and unstructured explanations. Practise with a peer playing the patient or relative.

Practise under timed conditions

Because both stations move at pace, untimed practice will mislead you. Run mock questions with a stopwatch, camera on, on the same laptop you’ll use on the day. Simulate the Qpercom experience: no notes visible, no second attempt. Record yourself once a week and review the recording. Most candidates find the gap between how they think they sound and how they actually sound is where the marks are lost.

Start earlier than you think

With roughly 74 applicants per post in 2025, the margins are narrow. We recommend beginning focused interview preparation at least eight to twelve weeks before early February, with intensive timed practice in the final four weeks. That gives you time to build a bank of structured answers, rehearse communication scenarios with real feedback, and iron out delivery habits before it counts.

Practise with a question bank built for this interview

The single most useful thing you can do once you understand the format is to work through a large volume of realistic questions, out loud, under time. Our question bank is organised around the two Wessex stations and mirrors the Structured Questions and Communication Skills content the panel actually tests. Use it as the daily practice layer sitting on top of your knowledge revision, and treat every question as a timed spoken rehearsal rather than a written exercise.

Frequently Asked Questions

What does the Cardiothoracic Surgery ST1 interview involve?

The 2026 interview is delivered online via Qpercom Recruit across 2-3 February 2026. You’ll sit two stations of roughly 25 minutes each: a Structured Questions station of five questions covering clinical and portfolio content, and a Communication Skills station of three questions. A panel of three assessors, typically Training Programme Directors and SAC members, scores each station, with Lay Representatives potentially observing.

How competitive is Cardiothoracic Surgery ST1?

Extremely. NHS England’s 2025 figures show 737 applications for 10 posts, a ratio of 73.7:1, up sharply from around 45:1 in 2024. All posts filled. From 2027, with the ST4 Thoracic route closing after the 2026 round, all entry into cardiothoracic training will funnel through ST1, so competition is expected to intensify further.

What topics come up in the Cardiothoracic Surgery ST1 interview?

The Structured Questions station draws on the person specification: clinical scenarios relevant to cardiothoracic practice, ethics and professionalism, judgement under pressure, and portfolio-linked content including reflection on complications and adverse outcomes. The Communication Skills station tests how you handle challenging conversations. Wessex notes specific content areas can change year to year, with full details given to invited candidates.

Does the question bank cover both interview stations?

Yes. The bank is built around the two-station Wessex format, with material for the Structured Questions station (clinical scenarios, ethics, professionalism, portfolio-linked reflection) and the Communication Skills station. Content is updated each year to reflect recent candidate feedback and the current person specification, so you’re practising against the format you’ll actually sit.

When should I start preparing for the Cardiothoracic Surgery ST1 interview?

We recommend starting focused interview practice at least eight to twelve weeks before the February interview window. Given the 73.7:1 ratio, most shortlisted candidates arrive well-prepared, so the margin sits in delivery under time pressure. Begin with the format, layer in station-specific practice, and build to full timed runs on Qpercom-style conditions in the final weeks.

What does the Cardiothoracic Surgery ST1 panel actually score you on?

Your final ranking combines your self-assessment score, which is carried over from the shortlisting stage, with your interview score across both stations. That means portfolio evidence still contributes to the total once you reach interview. It doesn’t reset. Alongside this, your Oriel post preferences determine how offers are allocated in rank order across the up-to-12 ST1 posts available for August 2026 entry.

Start Preparing for the Cardiothoracic Surgery ST1 Interview

Most candidates prepare by reading broadly across cardiothoracic topics without systematically working through the actual station formats. Strong candidates prepare differently. They practise against the actual station formats, rehearse timed responses, and align every answer to how the ST1 panel scores them.
