The interviewer wants to know if you have a specific area of knowledge and comfort. Perhaps you were the go-to biomedical technician for a particular piece of equipment, in your most recent role. Maybe the staff in radiology ask for you by name if their equipment ever goes down. This interview question is the time for you to brag a bit about your skills and abilities.
"The equipment that I worked on the most was our laboratory equipment. The staff in our laboratory unit always knew they could call me up and I'd be there in minutes. I have built a great relationship with the professionals in our hospital, and I look forward to doing the same at your facility."
"We have a great team at the hospital which I currently intern. Because of the large ER department, I have the opportunity to maintain their equipment most often. We can send two technicians at a time to assess their equipment and have been able to cut the wait time for repairs in half."
"I have worked very hard on my specialty over the years. Without a doubt, I am most experienced on robotic radiosurgery units."
