Have you ever used a hospital intercom system?

Now you may fumble over answering this question a bit but be sure to let the interviewer know you don't fumble during your overhead announcements. Let the interviewer know that you write down every detail that needs to be announced. You stick to your script and are sure to pronounce the providers name correctly and provide an accurate call back number. You can assure the interviewer that after your overhead page you will be waiting by the phone with a notepad and pen ready to take notes when the requested person calls back.
