A resume is a summary of your experiences, skills and accomplishments. The resume includes more detailed information than a letter of application. Ideally, it should make you and your attributes stand out in a positive way for an employer and show how you are different from the rest of the applicants. It is one way to get invited to a job interview.
Remember, the main purpose of a resume is to obtain a job interview. Therefore, your summary of relevant paid and non-paid work experiences, marketable skills and education should be written in terms of the prospective employer’s needs. The resume should relate your skills and accomplishments to the requirements of the job offered by the employer.
