A resume is the representation of your professional self. It is a concise compilation of your educational and professional experience, as well as the skills that make you desirable for the workforce. It is what you use to sell your merit and skills to potential employers.
Regardless of the type of resume you choose, aim to tailor your resume to the job you are applying to. While it’s perfectly acceptable to use a resume template, which you adapt to fit each job description, it’s a bad idea to send the same exact resume to multiple openings, even within the same field.
