For example, you could match your rate of speaking to your interviewer's. Say what first comes to mind. If you answer every question immediately on hearing it, you may create the impression that you're over-eager or you don't take enough time to assess a problem before offering a solution. Some questions require a pause before you respond. However, pausing before every question may make you appear overly cautious or even nervous.
Some pauses refresh and some proclaim a dull wit.
You can answer most questions quickly by thinking about your answer as the words leave the interviewer's mouth. Anticipate the second half of the question as you formulate the first part of your response. To keep the pace of your exchange flowing smoothly, try these tactics. Often the kernel of your response is in the question. If your nervousness distracts you, you might miss the point.
