Body language in the interview is closely related to the job-hunter's image .   Surely it is .   You should look the interviewer in the eye so as to show that you are carefully listening to him .   You can nod or ask questions at the right time to show that you have already understood or you are quite interested in his words .   When you are seated , bent forward a little with your hands crossed , to show you respect the interviewer .   Don't move from time to time . It is very impolite and will make you nervous .   Proper posture can show your confidence .   The best would be you have a smile on your face in the interview to win a good impression of the interviewer .   Pay attention to keeping eye contact as well .   Throughout the interview you should maintain patience .
