If you are answering a question using an example from your previous or current job and there is a lot of jargon or acronyms – try to use the more commonplace terms that more people are familiar with or explain what you mean in the beginning. If you are asked to describe a time when you lead a project – explain what the project was about, how many people you managed and any key points that demonstrate what a great job you did. What you don’t want to do is get side-tracked and give details that aren’t relevant to the question.
Keep on topic; take a moment before answering a question to organize the details in your mind. You don’t want to start answering, get sidetracked and forget the point you were trying to make. If you stay on topic and know what you are going to say, you are going to be able to keep the interviewer’s attention.
If you are a person of few words, practice with a friend or family member before your interview. Learn how to expand your answers so you give thorough information without living the interviewer wanting more. But if you are in doubt, less is better – an interviewer will ask follow-up questions if necessary.
