Quick answer

What questions are asked in an NHS dietitian interview?

Expect questions on why you chose dietetics and the service, prioritising a caseload, nutrition screening and assessment, a clinical scenario such as a patient at nutritional risk, working with the MDT, consent and capacity, safeguarding and HCPC standards. Panels want structured, safe reasoning and person-centred communication. Band 6 interviews add specialist depth, supervision, teaching and service improvement, and sometimes a presentation.

Key takeaways

Assess and check for risk before planning
Involve the patient, carers and the MDT
Escalate and follow local policy when unsure
Prepare five or six STAR examples
Band 6 adds supervision, teaching and improvement

NHS dietitian interviews usually ask why you chose dietetics and this service, how you would assess and prioritise patients, a clinical scenario such as a patient at nutritional risk on a ward, how you work with the multidisciplinary team, and questions on consent, safeguarding, documentation and your HCPC standards. Panels are looking for safe, structured reasoning, person-centred communication and a clear sense of when to ask for support. Band 6 interviews add specialist knowledge, supervising students and junior staff, and service improvement.

This guide covers Band 5 rotational and Band 6 acute, community and specialist posts. It explains how interviews tend to run, gives practice questions, shows how to approach a scenario at principle level, and includes a worked STAR answer, common mistakes and a preparation plan. The questions are typical practice themes, not questions taken from any real interview.

What questions are asked in an NHS dietitian interview?

Most dietitian interviews mix motivation, values-based questions, clinical reasoning and professional practice, usually built around the essential criteria in the person specification. Here are 12 practice questions reflecting common themes.

Motivation: Why do you want to work as a dietitian in this trust or service?
Prioritising: You have more referrals than you can see today. How do you decide who to see first?
Screening: What is the role of nutrition screening, and what would you do if a ward was not completing it?
Clinical scenario: A patient on a ward has a poor intake and recent unplanned weight change. How would you approach them?
Artificial nutrition: What would you consider before recommending tube feeding, and who would you involve?
Behaviour change: How do you support a patient who is not ready to make changes?
Communication: How would you explain dietary advice to someone with limited English or a learning disability?
Teamwork: Describe a time you worked with a nurse, doctor or speech and language therapist to improve a patient's care.
Consent and capacity: What would you do if a patient declined your recommendation?
Safeguarding: What would you do if you were worried about a child's growth and their home situation?
Professional standards: How do the HCPC standards guide your everyday practice?
Development: How do you keep your knowledge current, and what do you want to learn in this post?

What do they ask in a Band 5 dietitian interview?

Band 5 interviews focus on safe practice, organisation, communication and readiness to learn. Many posts are rotational, so panels often ask how you would adapt to moving between acute wards, outpatients and community teams.

Expect questions about your placements, managing a caseload, a time you asked for help, and how you would use supervision and preceptorship. You are expected to know your limits, follow local policy and escalate appropriately, not to know everything.

What is different about a Band 6 dietitian interview?

Band 6 panels expect more autonomy, depth in a specialist area, and evidence that you can support others and improve the service. Questions move from what you would do to how you have led, taught or changed something.

Acute: managing complex inpatients, such as those needing artificial nutrition, critical care input or surgical recovery, and working closely with medical teams.
Community: home enteral feeding, care home support, oral nutritional supplement prescribing in line with local formularies, and training care staff.
Specialist: areas such as renal, diabetes, oncology, gastroenterology, paediatrics or mental health, where panels probe your knowledge of current national and professional guidance.
Leadership: supervising students and Band 5 colleagues, delivering teaching, contributing to audit, and handling a colleague's practice concern.
Presentation: some Band 6 posts ask for a short presentation, often on service improvement or a clinical topic. Check your invitation letter.

How do you answer a dietetic clinical scenario in an interview?

Use a clear structure: gather information, assess, plan with the patient and team, act within your competence, document and review. Panels mark your reasoning and safety, not whether you quote a particular number.

Gather: read the notes, referral reason, medical history, medications and recent intake, and speak to the nursing team.
Assess: use a structured approach covering anthropometry, biochemistry, clinical condition, diet history and social factors, interpreting results in context and with the medical team.
Identify risk: consider risks such as refeeding problems, swallowing difficulty or fluid restrictions, and follow the local policy for managing them.
Involve the person: find out what matters to them, their preferences, culture and beliefs, and check consent and capacity.
Plan with the team: agree goals with the MDT, working with speech and language therapy on texture modification where swallowing is a concern.
Document and review: record clearly, set a review date and know when to escalate to a senior dietitian or the medical team.

Worked STAR answer: supporting a patient at nutritional risk

The STAR method (Situation, Task, Action, Result) keeps behavioural answers focused. Adding a short reflection shows learning, which panels value at every band.

Example answer: a patient with a poor intake on an acute ward (Band 5 dietitian)

Situation: On my final acute placement, I was referred an older man admitted with a chest infection. Nursing staff were concerned he was eating very little, and his screening had flagged him as at risk.

Task: I needed to complete a full assessment, agree a plan he was happy with, and make sure the ward team could carry it out.

Action: I reviewed his notes and bloods with my educator and checked for risks set out in the trust policy. When I spoke with him, he explained that he found the portions overwhelming and missed the foods he ate at home. With my educator's agreement, we set a plan around smaller, more frequent meals and snacks he chose himself, and agreed supplement use in line with the local formulary. I noticed he coughed at mealtimes, so I raised this with the nurse in charge and a speech and language therapy referral was made. I documented the plan clearly and added it to the ward handover.

Result: At review, his intake records showed he was eating more consistently, and he told me he looked forward to his snacks. The speech and language therapist's assessment gave the ward clear guidance for safer eating.

Reflection: I learned that asking what matters to the patient often unlocks a plan that works. I also now look for swallowing concerns at every first assessment rather than relying on the referral reason.

What do panels look for in a dietitian interview?

Panels usually score answers against the person specification and the NHS values. Strong candidates tend to show:

Safety: a structured assessment, awareness of risk and a clear sense of when to escalate.
Person-centred care: shared decision making that respects culture, preferences and capacity.
Evidence-based practice: reference to current national and professional guidance in general terms, without overclaiming.
Teamwork: genuine joint working with nurses, doctors, speech and language therapists, catering teams and carers.
Reflection: honest learning from mistakes and from supervision.
Fit with the service: knowing what the team does and why the post appeals to you.

What are common mistakes in dietitian interviews?

The most common mistake is jumping straight to a plan without assessing the person or checking for risk. Others are easy to fix with practice.

Skipping assessment: recommending a diet or supplement before gathering information.
Working alone: forgetting the MDT, the ward team, carers or catering staff.
Overreaching: describing decisions beyond your role or competence instead of escalating.
Ignoring the person: giving textbook advice without asking about preferences, culture, finances or readiness to change.
Vague examples: saying "we" throughout, so the panel cannot see your own actions.
Missing consent and documentation: leaving out capacity, consent and clear record keeping.

How do I prepare for an NHS dietitian interview?

Start with the person specification, build five or six STAR examples, then practise scenarios out loud. A week of focused preparation is often enough if you plan it.

Step 1, map the post: highlight each essential criterion and note an example that matches it.
Step 2, research the service: read the trust website and values, and if the advert invites it, call the contact named for an informal chat.
Step 3, refresh the essentials: revisit nutrition screening, the dietetic care process, local formulary principles, the HCPC standards and BDA professional guidance.
Step 4, build STAR examples: cover teamwork, a challenge, a mistake, a difficult conversation, prioritising and, for Band 6, leading or teaching.
Step 5, rehearse scenarios: practise structured answers to ward, community and specialist cases, ideally with a peer, practice educator or mentor.
Step 6, prepare logistics: plan questions to ask at the end, check whether there is a presentation, and test your set-up for an online interview.

Where can I find dietitian interview practice questions?

Useful free sources include NHS Jobs interview advice, your university careers service, practice educators, the British Dietetic Association and union representatives, and colleagues who have recently been through the process. Mock questions from a peer are often the most realistic practice.

Frequently asked questions

Do NHS dietitian interviews include a case study?

Many do. Some panels give you a short written case to read before the interview, while others describe a patient and ask how you would approach them. For Band 6 roles, a presentation or longer case discussion is more common. Your invitation letter usually explains the format. Practise talking through a structure of gather, assess, plan, act, document and review so you stay calm whatever case appears.

How should a newly qualified dietitian answer clinical questions?

Focus on safe, structured reasoning rather than trying to sound like a specialist. Explain how you would assess, which risks you would look for, who you would involve, and when you would escalate to a senior dietitian or the medical team. Mention following local policy and current guidance. Panels know you are new, so showing that you recognise your limits and use supervision well is a real strength.

What is a rotational Band 5 dietitian post?

A rotational post moves you between areas of a dietetic service over set periods, such as acute wards, outpatient clinics and community teams. Arrangements and rotation lengths differ between trusts, so check the job description. In interview, panels often ask how you would adapt to new teams and caseloads, how you would use supervision, and which areas you hope to develop in during the rotation.

How do I prepare for a Band 6 dietitian interview?

Review the specialist area named in the advert and the current national and professional guidance that applies to it. Prepare STAR examples showing autonomous clinical decisions, supervising students or colleagues, teaching, audit and service improvement. Be ready for a presentation if the invitation mentions one. Panels also often ask how you would manage a complex caseload and support a struggling colleague, so plan those answers.

What questions should I ask at the end of a dietitian interview?

Ask questions that show genuine interest in the role and your development. Examples include how the rotation or caseload is structured, what supervision and preceptorship look like, how the team works with ward and community colleagues, and what current projects or service improvements are underway. Avoid questions already answered in the advert. One or two thoughtful questions are usually enough to finish well.
