Paging Dr. Fauci. As a medical receptionist, it's your job to make sure patients and visitors get to where they need to be. You also need to be able to provide information to people who call or walk in with questions.
While being knowledgeable is important in this position, memorizing might be even more important. If a patient comes in with an emergency, you need to be able to stay calm while figuring out exactly where they need to go. And some hospitals are pretty big, so that can be a difficult task.
The job requires you to have a high school diploma before you can get started. And it's useful to be a good communicator as well. You wouldn't want to accidentally send a patient with a broken arm to the pregnancy center. Unless, of course, that patient was also pregnant - but that's another story.
