How to communicate effectively during job interview?

You need to sell yourself in half an hour during job interview. The first ten minutes are  most important. Some tips:

1) Dress well, arrive on time. Practice, practice and practice before interview.
 2) Create positive and pleasant climate of conversation vi greetings (verbal such as nice to meet you, and non-verbal such as shake hand),  eye contact, facial expression (smile), happy voice tone and volume.
3) When you speak, you need to use clear, meaningful, positive  and professional words. You need to use different words for different audience to avoid misunderstanding.
4) When you listen, you need to show your interest and understanding in body language, and not to interrupt.
5) Show your passion for the position and show that you are the top candidate.
6) Make a summary for each interview and find the reason you fail. Do not make the same mistake for next interview.
