A good CV is short and gives future employers a quick and concise overview of your qualifications and experience. A very well-crafted CV immediately captures attention and gives you a head start over other CVs that recruiters receive every day.
Your resume should contain
Assemble your CV in a structured and logical way (use short sentences, indents, uniform fonts and regularity in repeating font sizes). Make sure you do not exceed the range of two A4 pages, and that it is flawless.
Be honest, accurate, and ready to comment on any point of your resume. Tailor it to measure to highlight your skills and experience directly related to the job you are applying for. The compatibility of these factors determines who will be invited for an interview.
Constantly update your CV. New experience, skills, and qualifications will increase your value for potential employers.
Finally, attach a cover letter or email that will accompany your CV. Emphasize the most important points of your CV to highlight the link between the job requirements and your skill-set.
