Doing some ground work before a job interview is essential to making a good impression on an employer. Researching the organisation and the role itself will help you answer the employer's questions, and show you're keen for the job. The interview is your chance to present your skills, experience, personal qualities and other strengths as they relate to the position you are applying for. It is also an opportunity to get more information about the organisation or position. This will help you decide if it is the right job for you.
