The Power of Nonverbal communication and Body Language

Non-verbal can include

Shaking hands, posture, facial expressions, appearance, voice, tone, hairstyle, clothes, expression in your eyes, smile, how close you stand to others, how you listen, confidence, your breathing, the way you move, the way you stand, the way you touch people, color choice, silence.

Eye contact	Is this source of connection missing, too intense, or just right in yourself or in the person you are looking at?
Facial expression	What is your face showing? Is it masklike and unexpressive, or emotionally present and filled with interest? What do you see as you look into the faces of others?
Tone of voice	Does your voice project warmth, confidence, and delight, or is it strained and blocked? What do you hear as you listen to other people?
Posture and gesture	Does your body look still and immobile, or relaxed? Sensing the degree of tension in your shoulders and jaw answers this question. What do you observe about the degree of tension or relaxation in the body of the person you are speaking to?
Touch	Remember, what feels good is relative. How do you like to be touched? Who do you like to have touching you? Is the difference between what you like and what the other person likes obvious to you?
Intensity	Do you or the person you are communicating with seem flat, cool, and disinterested, or over-the-top and melodramatic? Again, this has as much to do with what feels good to the other person as it does with what you personally prefer.
Timing and pace	What happens when you or someone you care about makes an important statement? Does a response—not necessarily verbal—come too quickly or too slowly? Is there an easy flow of information back and forth?
Sounds	Do you use sounds to indicate that you are attending to the other person? Do you pick up on sounds from others that indicate their caring or concern for you?

Nonverbal communication is a rapidly flowing back-and-forth process. Successful nonverbal communication depends on emotional self-awareness and an understanding of the cues you’re sending, along with the ability to accurately pick up on the cues others are sending you. This requires your full concentration and attention. If you are planning what you’re going to say next, daydreaming, or thinking about something else, you are almost certain to miss nonverbal cues and other subtleties in the conversation. You need to stay focused on the moment-to-moment experience in order to fully understand what’s going on. 

Nowadays the interviewers have created a walkway to see the body language of interviewee and analyze its confidence level and they analyze that the words of presenter are matching the body language.Since the visual sense is dominant for most people, eye contact is an especially important type of nonverbal communication. The way you look at someone can communicate many things, including interest, affection, hostility, or attraction. Eye contact is also important in maintaining the flow of conversation and for getting the other person’s response.
