19 operating room nurse mock interview questions
The questions a Operating Room Nurse panel actually asks, with what each one is testing and what a strong answer contains. Click any question to run it in a live session: your AI interviewer will cover it and score how you answer.
- 1.
At the closing count, one swab is missing and the surgeon wants to start closing. What do you do?
Why they ask it: Retained surgical items are a serious never event. The panel is testing whether you will stop the process and follow policy even under pressure from a senior surgeon.
A strong answer: State the count is incorrect clearly and make sure the surgeon has heard and acknowledged it. Recount, search the field, the drapes, the floor, the bins and the wound with the surgeon's help, and follow the hospital policy for an unresolved count, which usually includes imaging before the patient leaves theatre. Document everything and complete an incident report. Never sign a count as correct when it is not.
- 2.
During the time out you notice the consent form lists the left knee but the site marking is on the right. What happens next?
Why they ask it: Wrong site surgery prevention depends on nurses speaking up. The panel wants certainty that you would stop the procedure.
A strong answer: Call a stop immediately and say what you have found. Nothing proceeds until the discrepancy is resolved by checking with the patient if awake, the medical records, imaging and the surgeon. Correct the documentation as required and report through the incident system. Everyone in the room is entitled and expected to halt the time out.
- 3.
You see the surgeon touch a non-sterile surface with their glove and continue working without noticing. What do you do?
Why they ask it: Sterile technique is the core of theatre nursing, and it often requires telling senior colleagues about their own breaks.
A strong answer: Tell the surgeon straight away in a clear, neutral way, have the glove changed and any contaminated instruments or drapes replaced, and continue. Strong answers show that protecting the patient from infection comes before any awkwardness, and that you would expect the same from others if you broke sterility.
- 4.
What is the difference between the scrub role and the circulating role, and which do you prefer?
Why they ask it: Checks your understanding of theatre roles and your experience. Many units want nurses competent in both.
A strong answer: The scrub nurse works in the sterile field, prepares and passes instruments, anticipates the surgeon's needs and keeps counts with the circulator. The circulator works outside the sterile field, advocates for the patient, manages the room, documentation, supplies and specimens and leads the counts and checks with the team. Give an honest account of your experience and interest in both.
- 5.
Anaesthesia reports a rising end tidal carbon dioxide, a rising heart rate and muscle rigidity shortly after induction. What might be happening and how do you help?
Why they ask it: Malignant hyperthermia is rare but deadly, and theatre nurses play a key role in the response.
A strong answer: Recognise it as a possible malignant hyperthermia reaction, call for help, bring the malignant hyperthermia cart, and support anaesthesia in stopping triggering agents and preparing dantrolene as directed, following the hospital protocol. Help with cooling measures, bloods and monitoring, and keep an accurate record of times and drugs.
- 6.
How do you protect a patient during a long procedure in an unusual position?
Why they ask it: Positioning injuries such as pressure injuries and nerve damage are preventable and a nursing responsibility.
A strong answer: Assess risk before the procedure, use appropriate padding and positioning equipment, protect pressure points and keep limbs in safe alignment to avoid nerve injury, secure the patient safely, recheck position after any movement, and check the skin at the end. Communicate risks with the team and document.
- 7.
Tell me about a time you had to speak up to a surgeon or senior colleague about safety.
Why they ask it: The theatre hierarchy can be steep. The panel wants evidence that you will advocate for patients in practice, not just in theory.
A strong answer: A specific situation, what you noticed, how you raised it clearly and respectfully, how the surgeon responded, what happened for the patient, and whether you escalated or reported it afterwards. Showing you would escalate further if ignored is important.
How the Operating Room Nurse interview runs
Typically an interview with the perioperative nurse manager and a senior theatre nurse or educator, sometimes with a surgeon or anaesthesia colleague involved. Questions focus on patient safety processes: the surgical safety checklist, counts, sterile technique and speaking up in a hierarchy. Expect to be asked whether you have scrubbed, circulated or both, which specialties you know, and how you would handle intraoperative emergencies. Some units offer a theatre visit or shadowing, and new graduates are often asked about perioperative training programmes.

Common questions in every interview
These come up in almost every Operating Room Nurse interview regardless of the company or the round.
- 8.
Tell me about yourself.
Why they ask it: Opens the interview and sets the frame. The interviewer is checking whether you can select what matters for this job rather than narrate your whole history.
A strong answer: A 60-90 second arc: where you are now, one or two proof points that match the posting, and why this role is the logical next step. Present, past, then future.
- 9.
Why do you want this role?
Why they ask it: Tests whether you read the job description or mass-applied. Weak answers are about what the candidate gets; strong answers connect to the work itself.
A strong answer: Two specifics from the posting or the company's actual work, plus an honest line about what you want to get better at here.
- 10.
Walk me through your resume.
Why they ask it: Checks that your story holds together and that the transitions were deliberate rather than accidental.
A strong answer: Chronological but fast, with a reason attached to each move and more time on the roles closest to this one.
- 11.
Tell me about a time you failed.
Why they ask it: Tests self-awareness and whether you own outcomes. Interviewers are listening for a real failure, not a disguised strength.
A strong answer: A genuine miss, what you specifically got wrong, the cost, and the concrete thing you changed afterwards that has since held up.
- 12.
Tell me about a conflict with a coworker or manager.
Why they ask it: Predicts how you behave when the team disagrees. The trap is blaming the other person.
A strong answer: The substance of the disagreement, what you did to understand their position, how it resolved, and what the working relationship looked like after.
- 13.
What's your greatest strength?
Why they ask it: Checks whether you know what you're actually good at and can prove it.
A strong answer: One strength that maps to the posting, plus a short example where it produced a measurable result.
- 14.
What's your greatest weakness?
Why they ask it: Tests honesty and whether you're actively working on something. Rehearsed non-answers ('I work too hard') read as evasive.
A strong answer: A real limitation that isn't core to the job, the system you built to manage it, and evidence it's improving.
- 15.
Tell me about a time you had to influence someone without authority.
Why they ask it: Almost every role depends on getting people who don't report to you to change course.
A strong answer: What you wanted, why they resisted, the evidence or framing that moved them, and what actually shipped as a result.
- 16.
Where do you see yourself in five years?
Why they ask it: Tests whether this job fits your trajectory, which is a retention question in disguise.
A strong answer: A direction rather than a title, and a line about the skills this role would build toward it. Vague ambition and rigid title-chasing both land badly.
- 17.
Why are you leaving your current job?
Why they ask it: Screens for red flags. Interviewers listen for how you talk about people you no longer work with.
A strong answer: Forward-looking and specific about what you're moving toward. Criticism of a former employer costs you more than it gains, even when it's deserved.
- 18.
What are your salary expectations?
Why they ask it: Checks whether you've done market research and whether you're in range before anyone spends more time.
A strong answer: A researched range with your target near the bottom of it, framed against the scope of the role. Deflect once if the posting has no band, then answer.
- 19.
Do you have any questions for us?
Why they ask it: The most under-prepared question in the interview, and the one that most changes the final impression.
A strong answer: Two or three questions about how the team actually works: what the first 90 days look like, how success is measured, what the hardest part of the job is.
