This question is similar to 'tell us about yourself' or 'what makes you a good candidate'. All these variations of questions are to allow you to tell the interviewer why you are the best candidate for the job. Tell the interviewer a few things that sets you apart from the rest of the candidates. Instead of choosing a skill or characteristic that is already listed on your resume, choose a solid skill that would be a benefit to the job. Communication skills, attention to detail in charting, ability to calm anxious allergy patients. If you are unable to identify a unique characteristic, we suggest you reach out to coworkers and family to get their opinion.
