What to Expect from the Occupational Medicine ST3 Interview

Occupational Medicine ST3 has become one of the most competitive ST3-level entry points in the UK. The 2025 round recorded 119 applications for 7 posts, a ratio of 17.0:1 (NHS England), up from around 5:1 in 2021 and 2.8:1 in 2019. Post numbers stay in the single digits, so small movements in applicant volume produce sharp swings, and every mark at interview matters.

The interview is delivered online through the Qpercom video platform, with slots booked via Oriel. The 2026 interviews are scheduled for 9 October 2026. The format is unusually compact: a single structured station lasting approximately 35 minutes, assessed by a panel of typically two consultants, usually accredited clinical or educational supervisors, with scoring integrated into the platform. The single station is split into two named subsections, Portfolio and Scenario, with no separate reading time, so the full 35 minutes is the relevant duration.

Portfolio Subsection

Delivered within the 35-minute station on Qpercom (with no separately published reading time), the Portfolio subsection explores your evidenced achievements and your commitment to the specialty. Expect probing around why Occupational Medicine specifically (not "why medicine"), what you understand about the field’s role bridging clinical care, workplaces and public health, and how your experience maps to the 2026 person specification. The panel scores your responses live; the published guidance doesn’t set out the maximum marks or exact domain weightings within the subsection.

Scenario Subsection

The Scenario subsection sits within the same 35-minute block and tests clinical judgement at a level consistent with completion of core medical or GP training, applied to occupational contexts. Based on the OMST 2022 curriculum and its Assessment Strategy, scenarios probe fitness-for-work decision-making, workplace risk assessment and hazard exposure, balancing work ability against clinical risk in workers with chronic disease or mental health conditions, and ethical dilemmas involving confidentiality and the dual obligations owed to employee and employer. Scoring is structured and integrated into the platform.

What the Panel Is Looking For

Across both subsections, the panel is scoring against the Occupational Medicine ST3 person specification. That means clear clinical reasoning applied to workplace contexts, structured communication, ethical awareness (particularly around consent and dual duties), and a credible, informed motivation for the specialty. Ranking combines your interview scores with the verified self-assessment used at shortlisting, and appointability requires clearing a threshold that isn’t numerically published, so consistent scoring across both subsections matters more than a single strong answer.

The Medibuddy 2026 Occupational Medicine ST3 Interview Question Bank

We’ve built the question bank around the reality of the Occupational Medicine ST3 interview: a single ~35-minute Qpercom panel that has to cover your portfolio and your clinical judgement in one sitting. It mirrors the station directly, splitting into a Portfolio strand and a Scenario strand. The Scenario cases run the specialty’s core occupational disease and employment-interface presentations, each opening with the referral and then unfolding through follow-up questions the way a panel actually probes, so you practise defending a position under pressure rather than reciting a first answer. Every question is written by high-scoring occupational medicine trainees and registrars who’ve recently sat the panel, and the question bank is refreshed each year using feedback from the most recent cohort.

What’s Included in the Occupational Medicine ST3 Interview Question Bank

The question bank follows the two subsections of the ST3 station directly, so what you practise maps onto what the panel scores.

How to Prepare for the Occupational Medicine ST3 Interview

Preparation for Occupational Medicine ST3 has to reflect what the interview actually is: a single ~35-minute online station on Qpercom, split between a Portfolio subsection and a Scenario subsection, scored by a panel of usually two assessors. That format rewards a different kind of practice from a multi-station circuit, and it’s worth building your prep around that reality from day one.

Understand the format before you start practising

Before you write flashcards or rehearse answers, get comfortable with the delivery. The interview runs online through Qpercom, booked via Oriel, with integrated scoring built into the platform. You’ll spend roughly 35 minutes in a single sitting with two panellists, moving between the Portfolio and Scenario elements without a room change. That means no "reset" between components: your energy, screen presence and clarity have to hold across the full block. Set up the exact environment you’ll interview in (same laptop, camera height, lighting, microphone) and rehearse in it.

Focus on knowledge and delivery equally

Occupational Medicine sits at the intersection of clinical medicine, employment law, ethics and public health, and the Scenario subsection can reach into any of those. Strong candidates read broadly around HSE guidance, fitness-for-work assessments, health surveillance, and the ethical tensions unique to OM (dual obligations to worker and employer, consent and confidentiality in a workplace context). But knowledge alone rarely scores well on Qpercom. Panels are marking structured answers, and delivery, signposting, prioritising, acknowledging uncertainty, is what turns content into marks.

Structure your Occupational Medicine ST3 interview preparation around each subsection

Portfolio subsection: Expect the panel to probe the evidence behind your self-assessment: publications, teaching, QI, leadership and prior occupational health exposure. Have the underlying documents in front of you and be able to summarise each item in 30-60 seconds, then discuss what you learned and how it applies to OM specifically. If you claimed a score, you should be able to defend it without hesitation.

Scenario subsection: Practise working through structured OM scenarios out loud: a fitness-for-work referral with conflicting information, a manager pressing for clinical detail, a worker refusing health surveillance, an ethical dilemma involving disclosure. Build a repeatable framework you can lean on when a scenario is unfamiliar.

Practise under timed conditions

Because everything happens in one 35-minute block, stamina and pacing matter. Rehearse full-length mock interviews on video, not isolated questions. Time yourself, watch the recording back, and cut the filler. You want to know what your answers sound like at minute 25, not just minute 5. Getting a current OM registrar or consultant to run a mock is one of the highest-yield things you can do. The specialty is small and their feedback is specific.

Give yourself enough runway

We recommend giving yourself at least two to three months of structured preparation ahead of the interview date (9 October 2026 for the 2026 round). That lead time lets you consolidate OM-specific knowledge, gather and organise portfolio evidence, and complete enough timed practice that the format itself feels routine. Leaving it to the final fortnight tends to produce candidates who know the content but haven’t rehearsed the delivery.

Practise with a question bank built for this interview

The most efficient way to train delivery is to work through questions written specifically for the Portfolio and Scenario elements of the OM ST3 interview, under Qpercom-style conditions, then refine each answer against structured feedback. That’s what the question bank is designed to do: give you the volume and structure of practice you can’t get from reading alone, mapped directly to how this interview is actually scored.

Frequently Asked Questions

What does the Occupational Medicine ST3 interview involve?

The Occupational Medicine ST3 interview is delivered online via the Qpercom video platform and lasts approximately 35 minutes. It’s structured as a single station split into two subsections, a Portfolio subsection and a Scenario subsection, with a panel of usually two consultant assessors and scoring integrated into the platform.

How competitive is Occupational Medicine ST3?

Very competitive. The published 2025 competition ratios show 119 applications for 7 posts, a ratio of 17.0:1, making Occupational Medicine one of the most competitive ST3 specialties that year. Post numbers stay small (single digits to low teens), so ratios swing sharply year to year. The 2026 figures aren’t yet published.

What topics come up in the Occupational Medicine ST3 interview?

The published format covers two areas: your portfolio and a scenario. Expect discussion of your evidence, motivation for the specialty, reflective practice, and applied scenarios covering fitness-for-work decisions, workplace risk and hazard exposure, and ethical dilemmas around confidentiality and the dual obligations owed to employee and employer. The exact sub-domains within the station aren’t published, but preparation should span the OMST 2022 curriculum, FOM guidance and GMC Good Medical Practice.

Does the question bank cover both interview subsections?

Yes. The question bank is organised into the same two subsections that make up the single Occupational Medicine ST3 station. The Portfolio strand covers motivation, the training pathway, academic and quality improvement evidence, teaching, leadership, communication and reflective practice. The Scenario strand works through the specialty’s core occupational disease and fitness-for-work cases, each with the follow-up questions a panel uses to probe your reasoning.

When should I start preparing for the Occupational Medicine ST3 interview?

We recommend giving yourself at least two to three months of structured preparation ahead of the 9 October 2026 interview date. That lead time gives you space to structure portfolio answers, rehearse scenario responses under timed conditions on a Qpercom-style setup, and refine your delivery without cramming in the final week.

Start Preparing for the Occupational Medicine ST3 Interview

Most candidates prepare by reading widely across occupational health topics and hoping it comes through on the day. Strong candidates prepare differently. They practise against the actual station format, rehearse structured answers under time, and align their delivery to how the Occupational Medicine ST3 interview is genuinely assessed.
