Know the basics

There are only three main questions an interviewer wants to ask
Can you do the job?
Will you do the job?
Will you fit in?
Structuring your planning around these three areas, will help you to cover the most crucial issues likely to be covered during the interview, and give you the chance to prepare your key statements and responses to market yourself most effectively.
Can you do the job?
Questions in this area are intended to probe your background. It is unlikely you would have been invited for interview if your qualifications and experience on paper did not match the criteria for the job. Most interviewers therefore will spend about 15% of the interview on this area.
