“It’s not only what you say, it’s how you say it” is absolutely true when you are interviewing in person. Your spoken content only provides 7% of the message the interviewer receives. Your body language delivers 55% and the tone of voice the remaining 38%. Therefore, you need to focus on your body language and voice as well as the words you use in your job interview answers.
The interviewer will often analyze your body language, your mannerisms and facial expressions and if your body language is perceived as negative, this could cost you the job!
