The importance of body language is often mentioned,but doesn’t always get the attention it deserves.After all,before a word has even been spoken,your body language will have already given people their first impression of you.Additionally, your body language will also give out a lot more information.Based on your body language it can be seen if you are self-confident.It can also show if you are a busy or a quiet type and it helps give an impression of whether you are speaking truthfully or not.Body language can show how enthusiastic you are and if you are a nice person.someone who will take his work seriously, but also someone who has a sense of humor and can enjoy a joke from time to time.The members of the application committee will ask you questions,but your answers won’t only be oral.The committee will not only pay attention to what you say, but also to how you say it! Body language will determine first if it ‘clicks’,and sometimes all it takes is just a few seconds.Everybody uses body language,but it takes place mostly at a subconscious(下意识的) level.Using body language appropriately, you can definitely increase your chances of getting a job.
