1. I have an innate interest in people.
2. I'm curious about people.
3. I like people.
4. I like talking to people.
5. I'm a very good listener.
And they can tell that about me and in turn they tell me EVERYTHING about themselves, and before I know it, I understand their value system and if I'm able, I can either engage them as a candidate, or provide them better service as a hiring manager. It's really that easy.
