Interviewers want to hear about that one unique skill that sets you apart from the other candidates applying for this job. Think of your answer as your 'elevator pitch' or your qualifying statement. If you can't think of ways that you are unique, ask a few friends or family members what they feel sets you apart from other people. Their observations may help you understand how you are perceived.
Perhaps you already know what sets you apart! This skill could include any industry accolades, exceptional achievements, additional industry related training, a second language, or how involved you are in the community. Don't be afraid to brag about yourself a bit. In an interview, you are your most influential advocate.
"You should hire me because I'm qualified and passionate about your cause. I am excited about the idea of delivering value to your organization and will hustle for the opportunity to go above and beyond for your customers."
