You're naturally friendly and are keen to help people out. That, combined with your multi-tasking skills, made you consider being a front desk clerk where your skills will have the opportunity to grow. Communicate to the interviewer that you're self-motivated and passionate about your job; you're not one to fizzle out after a few years in the role.
Talking about ourselves in this way can be challenging. We recommend reaching out to a few colleagues, family members, and friends. Ask them for their opinion. You'll probably be surprised at the consistency in their responses! Their answers will give you insight into how to answer this question. Tell the interviewer what sets you apart, and explain how your co-workers, family members, and friends have encouraged you with your gift in this area.
