In your NHS Consultant Interview, You are almost guaranteed to be asked this question.
Tell us about a mistake you’ve made
It’s a high-stakes question. Not because they expect perfection, but because they want to see how you handle the reality of clinical work: the slip-ups, the decisions under pressure, the missed details. Handled well, this is your chance to demonstrate maturity, self-awareness, and leadership potential.
Let us learn how to give a confident, structured answer using three critical principles.
1. Choosing the Right Kind of Mistake: The “Manageable but Meaningful” Rule
You’re not expected to share a dramatic clinical failure or a minor administrative oversight. The most effective examples are those everyday-but-impactful moments that offer insight and growth.
“I sent an email to the wrong consultant. They replied correcting me.”
No real consequence. No space to show growth or learning.
” I administered medication meant for another patient.”
This crosses a red line. Too serious, and potentially raises concerns about your safety as a clinician.
I chased a CT scan for a patient and assumed it was normal without checking the formal report. I updated the team, but the report later showed an abnormality that required follow-up.
This kind of error is human and relatable, yet it had an impact and led to meaningful learning.
Key Tip: Look for mistakes that had consequences, but that you responded to with professionalism and reflection.
2. How to Structure Your Answer: Use the “iSTARR” Framework
You’ve chosen the right story. Now you need to deliver it clearly. The iSTARR model keeps your answer concise, honest, and impactful.
iSTARR stands for:
- i – Introduction: Your role and setting
- S – Situation: The clinical context
- T – Task: What you were meant to do
- A – Action: What went wrong and how you handled it
- R – Reflection: What you learned
- R – Result: What changed as a result
Example Using iSTARR:
Introduction: I was an FY2 on a busy medical ward post-take.
Situation: A Consultant asked me to chase a CT abdomen for a patient with unexplained pain.
Task: I was expected to retrieve and communicate the result during the ward round.
Action: I checked the images on PACS and, assuming the scan was normal, informed the team. I didn’t realise the report wasn’t yet finalised. The next day, the report showed a small lesion needing follow-up. I immediately informed the consultant, contacted the patient, and arranged the necessary outpatient care.
Reflection: I realised that assumptions, even under time pressure, can lead to breakdowns in care. It taught me to always wait for formal radiology reports before drawing conclusions.
Result: I raised the issue at our governance meeting. We agreed on clearer local guidance, and I’ve since seen fewer communication errors around pending scans. I also started mentoring new FY1s on safe handover practices.
Key Tip: Spend less time on the story, more on the reflection and result. That’s where your professional insight shines.
3. Learning from Mistake and Showing You Think “Like a Consultant”
One of the clearest ways to stand out in an interview, especially for senior or training roles, is to show that you don’t just learn from your mistakes, you think systemically, like a consultant would.
Consultants don’t only ask, “How do I fix this now?” They ask, “How do we stop this happening again?”
It’s this broader thinking , about safety, systems, and shared learning, that signals you’re ready for the next level.
To show you think like a consultant, consider:
- Did you report the incident formally?
- Did you raise it with the wider team or at governance?
- Did your actions lead to a change in process, education, or awareness?
- Are you helping junior colleagues avoid the same pitfall?
Example (continuing from earlier):
Reflection and Result: After recognising the issue with assuming a scan was normal without a formal report, I submitted a Datix and brought the case to our governance meeting. Several clinicians acknowledged similar assumptions had caused confusion or delays.
As a result, we created a ward-level protocol for communicating scan results, and added a visual alert in our electronic system showing when a report is pending.
I also incorporated this learning into our induction for new doctors, highlighting the importance of waiting for formal documentation before acting on imaging.
I’ve noticed a tangible drop in similar communication errors since. It reminded me how one small mistake can improve care across an entire team when it’s approached thoughtfully.
Why This Works:
This kind of answer shows you’re not only reflective, you’re proactive, solutions-focused, and safety-conscious.
It demonstrates:
- Clinical leadership
- A systems approach to care
- Emotional intelligence
- Commitment to team-based improvement
That’s exactly how consultants think — and exactly what panels are hoping to see.
Recap: To give a strong answer…
- Pick a meaningful, non-catastrophic mistake
- Use the iSTARR framework to structure your response
- Highlight learning and governance to show leadership
The goal isn’t to prove you’re flawless. It’s to show you’re self-aware, accountable, and always improving, exactly the kind of clinician every team wants.
Final Thoughts: It’s Not the Mistake. It’s What You Do With It
Everyone makes mistakes. The question isn’t if, it’s what happens next.
A strong interview answer shows:
- Self-awareness
- Responsibility
- System-level thinking
- A mindset focused on growth and improvement
By choosing the right kind of example, structuring it clearly using iSTARR, and showing you think like a consultant, you don’t just answer the question well.
You show them you’re ready for more.
