Interview Questions to Ask a Dietitian / Nutritionist Candidate
Questions that surface real evidence of measurable patient outcomes from evidence-based nutrition plans — plus what to actually listen for in the answer, not just whether they say the right buzzwords.
1. How do you assess the nutritional needs of a patient with type 2 diabetes in a first appointment?
What to listen for: Diet history, labs, medications, lifestyle, goals, cultural food habits, and a plan that is realistic for the person.
2. A client wants to follow a trendy elimination diet that has weak evidence. How do you respond?
What to listen for: Respectful listening, explaining the evidence, assessing risks of nutrient gaps, and offering safer alternatives.
3. Tell me how you adapt advice for a client who is on a tight budget and has limited cooking facilities.
What to listen for: Practical, low-cost options, simple preparation, shopping suggestions, and avoiding judgement, so the client can realistically follow the advice with limited money and cooking facilities.
4. A patient shows signs of disordered eating while you are discussing weight loss. What do you do?
What to listen for: Stopping weight-focused advice, assessing safely, involving the wider care team, and appropriate referral.
5. What would you do in your first 30 days in this dietitian / nutritionist role?
What to listen for: Whether their plan is grounded in the role's actual must-haves (nutritional assessment and medical nutrition therapy) or generic ("get to know the team"). Specificity here signals real understanding of the job, not just interview prep.
6. Why are you leaving your current role, and why this one specifically?
What to listen for: Forward-looking motivation tied to something concrete about this role, versus badmouthing a past employer or vague dissatisfaction. Watch for whether their reasons actually match what this role offers.

Frequently asked questions
How many of these questions should I ask in one interview?
3-4 is realistic for a 30-45 minute interview once you leave room for follow-ups and the candidate's own questions. Divide competencies across panel members rather than every interviewer asking all of them — see the Interview Scorecard tool for a structured version of this.
