In the States, good eye contact is important, but in some countries around the world, eye contact could be quite a problem because it would likely lead to an unintended misinterpretation of the other party.
When you are speaking, make sure to keep a smile in your voice. Attitude comes through in your voice.
The most important thing to wear!
The most important skill, listening is also the most difficult. You don’t need to fill in any of the quiet moments of a conversation. Even if you disagree with something, listen and nod to show that you are at least listening to the other’s opinion. And certainly don’t interrupt, especially a complaint, which is often not much more than just a need for an outlet or a listening ear. Concentrate on what the other person is saying, not what you would say next.
Remove all barriers between yourself and the person with whom you are speaking. This also shortens the distance between you two and shows that you are interested in what the other person is saying. Talking over the top of your eyeglasses is a definite no-no.
Name tags are worn high and on the right. Use the buddy system to introduce each other to someone if you have to. You don’t have to rush your conversation while you circulate. Just have fun and don’t race through your words. Tell what your company does in a very brief sentence after you have introduced yourself. Ask for business cards if necessary and put theirs in your left pocket while your own are in your right pocket.
