Your answers to a few key questions may determine if you get a job offer. We strongly recommend that you write out your answers to typical questions and practice your answers out loud so that you will be better prepared and more at ease at the interview.
The interviewer is trying to get to know you with this question. You should provide a brief background (education, work experience, etc.), who you are (skills you possess and what you like to do), career goals, and the nature of the work that you want to do. Remember to focus on professional rather than personal information
Employers ask behavior-based questions to learn about how you have responded to specific situations in the past. Keep in mind that by them asking about your past behavior, they can get a better sense of how you will perform on the job in the future.
