While you are the subject matter expert on your product, it is important to remember that the surgeon is the ringleader in the operating room. Make sure that your answer acknowledges this and shows you will provide the respect that is due!

If you have never been in the operating room to draw on a past experience, you will likely have similar relevant experiences from overcoming obstacles or solving problems with difficult customers. Use those experiences to show that you understand the skill these situations require!

Avoid responding in a manner that makes this situation sound trivial. Although common, this is a high-stress situation in which someone's health depends on how you handle it. It's very important that the interviewer knows that you understand this responsibility and will shoulder it well.

"I would ensure I remained calm and spoke slowly and clearly. I'd reiterate to the surgeon where I understood they were based on the progress they had stated and I had seen to ensure we were aligned on what had been accomplished. From there, I would work to advise on best practices based on similar techniques for insertion or application depending on the product. I would break it down into as many steps as possible to slow down the process and remove as much margin for error as possible."
