Personality tips for BPO interviews : Body language

Walk with confidence; keep your chin parallel to the floor. Shake hands firmly when you meet the interviewer. Look at people and talk. Maintain eye contact; however, don't stare.

Keep your hands out of the pockets and don't fiddle with things like pen and paper. Don't fold your hands while talking to someone -- it conveys the impression that you are not open to their conversation.

And if you want to make a whole world of difference, SMILE.
