Getting a surgical tech job is competitive. You need credentials, clinical hours, and the ability to walk into a room with a hiring manager or surgeon and demonstrate that you belong in an OR. This page covers the questions most likely to come up, with sample answers you can adapt.
Questions are grouped into three categories: behavioral, technical, and scenario-based. Most surgical tech interviews will include all three.
Beyond credentials, interviewers are assessing two things: can you function under pressure without creating problems, and will you fit the team dynamic in the OR. Surgeons and scrub techs work in close quarters with high stakes. They want people who are precise, calm, and direct when something goes wrong.
Know your resume cold. Know the specific procedures listed in your clinical rotation. If you're NCCT or NBSTSA certified, be ready to explain what that process required.
Behavioral questions ask you to describe how you handled a past situation. Use the STAR format: Situation, Task, Action, Result.
1. Tell me about a time you caught an error before it became a problem.
What they're evaluating: Attention to detail, initiative, communication habits.
Sample answer: "During a knee replacement, I noticed the cement we had opened was a different brand than what the surgeon preferred for that specific case. The circulator had already pulled the case cart. Before we started, I flagged it quietly to the circulator and confirmed with the surgeon. We swapped it out in time. It's the kind of thing that could have gone unnoticed until it mattered."
2. Describe a time you had a conflict with someone on the surgical team.
What they're evaluating: Emotional regulation, professionalism, ability to stay focused on patient safety over ego.
Sample answer: "There was a circulator I worked with who would frequently skip read-back on verbal orders. I brought it up with her directly after the case, not in front of anyone. She was receptive. We didn't have a problem after that. I don't let things like that go because the OR is the wrong place for miscommunication to compound."
3. Tell me about a time you had to adapt quickly when something unexpected happened mid-case.
What they're evaluating: Composure, clinical judgment, whether you communicate or freeze.
Sample answer: "We were mid-laparoscopic cholecystectomy when the surgeon identified adhesions that weren't visible on imaging. He decided to convert to open. I already had the open instruments on a back table as standard prep. I had the field transitioned in under two minutes. He acknowledged it after the case. I think about scenarios like that before I scrub in."
4. How do you handle working with a surgeon you find difficult?
Sample answer: "You learn their preferences and you stay ahead of them. Most difficult surgeons are difficult because they've worked with techs who weren't prepared. If I know the procedure, anticipate the next instrument, and keep the count tight, there's usually not much friction. If there's a real interpersonal issue, I address it professionally outside the OR."
5. Describe how you manage your workload when you have multiple cases in a day.
Sample answer: "I prioritize based on case start times and complexity. I confirm preference cards the day before when possible. During turnover, I run through a mental checklist before the next patient enters the room. Fatigue is real in multi-case days, so I'm deliberate about not rushing through steps I'd normally be methodical about."
These questions assess your clinical knowledge. If you're NCCT or NBSTSA certified, most of these should be familiar territory.
6. Walk me through how you set up and maintain a sterile field.
Sample answer: "I start by verifying the integrity of all sterile packages before opening. I open items toward the back of the back table, never reaching across the sterile field. I maintain a 12-inch margin from the edge as the non-sterile border. Once scrubbed, I keep my hands above the waist and in front of me. Anything that leaves my line of sight gets questioned. If there's any doubt about contamination, I treat it as contaminated."
7. What is your process for surgical counts, and what do you do if a count is incorrect?
Sample answer: "Counts are done at the start of the case, before closure of any cavity, before closure of the wound, and at skin closure. I count instruments, sharps, and soft goods with the circulator, both calling out items simultaneously. If a count is off, I stop and notify the surgeon immediately. We do not close until the count is reconciled or an X-ray confirms no retained item. That protocol exists for a reason and I don't negotiate it."
8. How do you handle a contaminated instrument during a case?
Sample answer: "Remove it from the sterile field immediately, pass it off to the circulator, and replace it. I don't use it, I don't set it aside and come back to it. If there's any ambiguity, I call it out. The surgeon may not be happy about the delay, but they'd be less happy about the alternative."
9. What surgical specialties have you scrubbed, and which do you have the most experience in?
Guidance: Be specific here. List specialties and your approximate case volume if you can. Vague answers undermine credibility. If you're early in your career, name the specialties from your clinicals and be direct about where you're still building experience.
10. What is the difference between standard and flash sterilization, and when is each appropriate?
Sample answer: "Standard sterilization uses a full cycle with appropriate dry time for packaged instruments before use. Flash, now more precisely called immediate-use steam sterilization, is for unpackaged instruments needed urgently when there isn't time for standard processing. It's not a substitute for proper sterilization and should not be used routinely. AORN guidelines are clear on this."
11. How do you handle a case involving a patient with a latex allergy?
Sample answer: "The case gets flagged before setup. I pull latex-free gloves, latex-free tourniquets if applicable, and check every supply item in the room for latex content. The OR should be notified at time of scheduling so the room can be cleared if needed. I confirm the allergy status again during the time-out."
12. What do you know about the Universal Protocol and how do you apply it?
Sample answer: "Universal Protocol covers pre-procedure verification, site marking, and the time-out. I participate actively in the time-out, not passively. I verify the patient, procedure, site, and that any required imaging is in the room. If something doesn't match, I say something before the incision. It's one of the few moments in a case where every person in the room is aligned on the same information."
These questions put you in hypothetical situations to see how you think under pressure.
13. You notice the surgeon is about to make an incision on the wrong site. What do you do?
Sample answer: "I call a time-out immediately and say it directly: 'I need to stop before incision, I believe we have a site discrepancy.' You don't wait, you don't hope someone else catches it. Wrong-site surgery is a never event, and speaking up in that moment is part of the job regardless of who is in the room."
14. You're in the middle of a long case and realize you are approaching fatigue. What do you do?
Sample answer: "I communicate it. I let the circulator know I may need a relief scrub, and I stay focused on the immediate task in front of me. Fatigue-related errors in the OR are documented and avoidable. Asking for relief is not weakness, it's clinical judgment."
15. A surgeon asks you to hand them an instrument you believe is contaminated. How do you handle it?
Sample answer: "I don't hand it. I tell them directly that I believe the instrument is contaminated and I hand them a replacement. If they push back, I explain the concern. The sterile field is my responsibility. I'm not going to compromise patient safety to avoid an uncomfortable moment."
16. You're setting up for a case and realize a piece of equipment the surgeon needs is not in the room. The patient is already in pre-op. What do you do?
Sample answer: "Notify the circulator immediately so they can locate it. Assess whether we can delay patient transport to the room by a few minutes while it's resolved. Do not bring the patient back until the room is ready. Better to manage expectations in pre-op than to create a problem once the patient is on the table."
17. A new circulator makes a sterile technique error that you observe. How do you respond?
Sample answer: "I address it in the moment, calmly and directly. Something like: 'That item is no longer sterile, pull it out and let's replace it.' Not confrontational, just factual. After the case, I'd follow up with them privately to make sure they understood what happened and why. I'd rather have that conversation than let it slide and see it happen again."
Asking good questions signals engagement and helps you evaluate whether this position is right for you.
