You must be prepared to sell your marketable skills to the employer. Be prepared to offer behavioral examples of your skills and abilities. Such examples will come from your work, internship, co-curricular, and leadership experiences. Know your resume inside and out and be prepared to highlight experiences and accomplishments that relate to the qualifications that the employer is seeking. Know your short and long term goals and be prepared to discuss them with the employer.
Employers are impressed with candidates who articulate clear, well defined goals.
Your short term goal should always be the immediate position for which you are interviewing. Lastly, clarify your values. Be cognizant of what is important to you and how these values shape your career decisions. First, be fully informed about the job for which you are interviewing. Start with the job posting - this will describe the job qualifications.
