What to Expect from the Clinical Genetics ST3 Interview

Clinical Genetics ST3 is recruited nationally through the Physician Higher Specialty Training (PHST) process, with applications made via Oriel. Competition has risen sharply: in the 2025 round, 84 applications were made for 15 posts (5.6:1), up from 1.93:1 in 2019. Post numbers stay small, so modest shifts in applicant volume move the ratio quickly.

Interviews are currently conducted online (format confirmed in your invitation and subject to change) and run to approximately 40 minutes across two stations of 15 minutes each, with a short transition between them. Each station is staffed by a separate pair of interviewers. Across the two stations you’ll answer four scored question areas, plus communication skills assessed throughout. Each area is scored 1-5 by the interviewers, producing a Raw Interview Score (RIS) out of 50. Based on the published PHST scoring model, to be classed as appointable candidates typically need no score of 1/5, no more than two scores of 2/5, and an RIS of 30 or above. Weighted interview and application scores are combined to produce the total ranking score.

Station 1

Station 1 covers two scored areas: a clinical scenario and a question on new technologies.

Clinical Scenario. You’re given a brief two-to-three-sentence hypothetical scenario in which you’re involved, plus short preparation time to make notes (destroyed after the station). The discussion, around 10 minutes, covers the steps you’d take, management issues, further information you’d gather, and how you’d communicate with patients, families and colleagues. It tests structured reasoning and professional judgement, not rote genetics recall.

New Technologies in the NHS. A shorter question of around 5 minutes, with no advance preparation, on new technologies and their introduction into the NHS. Expect topics relevant to genomic medicine, mainstreaming and service delivery. Interviewers are looking for informed opinion, awareness of national context, and balanced reasoning about benefits, limitations and implementation.

Station 2

Station 2 covers two further scored areas: your career and engagement with training, and your commitment to the specialty.

Application, Career and Engagement with Training. Approximately 8 minutes reviewing your application form, career progression and engagement with training and learning to date. Scoring reflects the breadth and quality of your achievements and how you speak to them, not the achievements alone. Be ready to expand on any entry on your form.

Suitability and Commitment to Clinical Genetics. Around 7 minutes exploring why Clinical Genetics, and why now. This is your chance to expand on the motivation section of your application: what draws you to the specialty, what you’ve done to test that interest, and how you fit its interdisciplinary way of working with genetic counsellors and laboratory scientists.

What the Panel Is Looking For

Across both stations, panels are scoring against the trainee level expected at entry to ST3. They want structured clinical reasoning, considered handling of uncertainty, awareness of the wider NHS and genomic landscape, and evidence of sustained engagement with the specialty. Communication runs through every question: how you’d talk to a family in the scenario, and how clearly you talk to the panel.

The Medibuddy 2026 Clinical Genetics ST3 Interview Question Bank

We’ve built the question bank around the Clinical Genetics ST3 interview as it actually runs, covering every station you’ll face and the themes examiners return to: familial confidentiality and disclosure, consent for genomic testing, predictive testing in minors, incidental findings, breaking difficult news, and the reflective practice examiners expect you to draw from your ePortfolio. Each station is worked through with model answers, marker-facing structure and the reasoning that distinguishes a scoring answer from a safe but undifferentiated one. The bank is written by high-scoring Clinical Genetics registrars and refreshed each year against recent candidate feedback.

What’s Included in the Clinical Genetics ST3 Interview Question Bank

Clinical Genetics ST3 is interviewed across two 15-minute stations totalling around 40 minutes, with four scored question areas plus communication skills assessed throughout. The bank is organised around the themes assessors weave through those stations.

How to Prepare for the Clinical Genetics ST3 Interview

Clinical Genetics ST3 is a small, specialised round with limited posts and comparatively little published preparation material. That makes structured practice more valuable here than in larger specialties, not less. The approach below is built around the two-station PHST format and the four scored question areas.

Understand the format before you start practising

Before you rehearse a single answer, get the mechanics right. The PHST Clinical Genetics ST3 interview runs across two 15-minute stations, each with a separate pair of interviewers, and lasts around 40 minutes in total. You’ll face four scored question areas: a clinical scenario (~10 minutes with brief prep time from a two-to-three-sentence stem), new technologies in the NHS (~5 minutes, no prep), your application form and career to date (~8 minutes), and your suitability for and commitment to the specialty (~7 minutes). Communication skills are marked throughout. Every question is scored 1-5 by the interviewers, so a weak answer in one area can’t easily be rescued by a strong answer elsewhere.

Focus on knowledge and delivery equally

Clinical Genetics interviewers reward candidates who can think clearly about a scenario and communicate it as they would to a family in clinic. Knowing the content of the Genomic Medicine Service, the role of the 100,000 Genomes Project or the introduction of whole-genome sequencing is only half the job. You also need to structure an answer under time pressure, signpost your reasoning, and adjust register when the scenario shifts from talking to a colleague to talking to a patient. Practise both dimensions in parallel. A question bank of specialty-specific practice questions is the most efficient way to drill this.

Build preparation around each station

For the clinical scenario, work through short two-to-three-sentence stems and rehearse a repeatable structure: immediate steps, information you’d gather, management issues (including consent, family implications and MDT input with laboratory scientists and genetic counsellors), and how you’d communicate with the family. For the new technologies question, be ready to discuss NGS, whole-genome sequencing, non-invasive prenatal testing, pharmacogenomics and their implementation into NHS pathways, including cost, equity and consent considerations. For the portfolio and career question, know your own form cold and be able to explain choices, gaps and achievements in a minute or two each. For the commitment to specialty question, have concrete evidence ready: taster experience at a Regional Genetic Centre, British Society for Genetic Medicine engagement, genetics-focused audit, teaching or research.

Practise under timed conditions

The station timings are tight. Ten minutes for a clinical scenario disappears quickly if you don’t have a structure. Rehearse with a clock visible, cap yourself at the real question durations (5, 7, 8 and 10 minutes), and get comfortable finishing on time rather than being cut off. Because published prep material for Clinical Genetics is thin, most successful candidates run mock interviews with current trainees or peers, supplemented by a structured question bank. Do the same, and record yourself so you can hear the delivery issues you can’t feel in the moment.

Start earlier than you think

We recommend giving yourself at least eight to twelve weeks of structured preparation. Clinical Genetics is a small specialty with limited peer support and few published question sets, so the front-loaded work of building answer frameworks, reading around genomic medicine policy, and lining up mock partners takes longer than in higher-volume specialties. Starting once shortlisting is confirmed is usually too late.

Bring it together with structured practice

The principles above only work if you rehearse them out loud, against real question stems, under time. Our Clinical Genetics ST3 question bank is built around the two-station PHST format and the four scored question areas, so you can practise each in isolation, then run full mock stations end-to-end. Structured repetition against the real format is what converts knowledge into a scoring answer on the day.

Frequently Asked Questions

What does the Clinical Genetics ST3 interview involve?

The interview is delivered as two 15-minute stations, each staffed by a separate pair of interviewers, totalling around 40 minutes. Across the stations you’ll face four scored question areas: a clinical scenario, a question on new technologies in the NHS, a review of your application and career to date, and a question on your commitment to the specialty. Communication skills are scored throughout.

How competitive is Clinical Genetics ST3?

Competition has risen sharply. NHS England’s published figures show 84 applications for 15 posts in the 2025 round, a ratio of 5.60:1, compared with 1.93:1 in 2019. Post numbers remain small, so modest growth in applicant volume moves the ratio quickly. Treat it as reasonably competitive and prepare accordingly, particularly given how few candidates each station scores.

What topics come up in the Clinical Genetics ST3 interview?

Expect a clinical scenario asking how you would manage the case, gather further information and communicate with those involved; a question on new genomic technologies and their introduction into the NHS (think Genomic Medicine Service, whole genome sequencing, incidental findings); a structured discussion of your portfolio and career; and a question probing your suitability for and commitment to genetics.

Does the question bank cover every station?

Yes. It’s built around the PHST interview structure, with dedicated practice for the clinical scenario, the new technologies question, the application and career review, and the commitment to specialty question. Communication skills are trained throughout, since they’re scored across both stations rather than assessed in isolation.

When should I start preparing for the Clinical Genetics ST3 interview?

We recommend starting at least eight to twelve weeks before your interview date. Published prep material for genetics is thinner than for larger specialties, so time is needed to read around genomic policy, rehearse scenario answers aloud, and arrange mock practice with peers or current trainees. Starting early also lets you refine how you talk about your portfolio before the review question.

Start Preparing for the Clinical Genetics ST3 Interview

Most candidates prepare by reading broadly across genomics and NHS hot topics. Strong candidates prepare differently: they rehearse under timed conditions, structure answers to the panel’s assessment criteria, and practise the clinical, ethical and personal stations the way they’re actually scored on interview day.
