Carefully examine the job description During your prep work, you should use the employer’s posted job description as a guide. The job description is a list of the qualifications, qualities and background the employer is looking for in an ideal candidate. The more you can align yourself with these details, the more the employer will be able to see that you are qualified. The job description may also give you ideas about questions the employer may ask throughout the interview. 2. Consider why you are interviewing and your qualifications Before your interview, you should have a good understanding of why you want the job and why you’re qualified. You should be prepared to explain your interest in the opportunity and why you’re the best person for the role.
