Remember you resume will be read by humans as well as by machines which will scan for the right keywords. So put some time and energy into your keywords when you write. Resumes must grab the attention of both the human and the computer scanner.
Tailor the resume to the job description Make sure that every time you apply for a job that you adjust your resume to the particular place you are applying. Read through the job description and make notes of any areas being focused on. Make sure to add information to your resume that highlights your abilities in those areas and makes you more attractive for the particular position you are applying for.
The resume that lands you the job interview isnt a simple listing of your past duties or work experience. It has to convince readers that you have the required skills and abilities to exceed the expectations of the position so your resume should be structured in a way that arouses employers interest in you and gives them reasons as to why you are more qualified than others while encouraging the employer to get in touch with you for an interview.
Functional resumes are good when you have little to zero work experience (or new grads). This type of resume allows you to showcase skills that fit in with the job requirements. Fair warning: most recruiters and hiring managers dont like this format and feel as though you may be hiding something. If you have a chronological resume you do not want to have one part chronological and one part functional because it will throw off the entire formatting and may confuse the employer about your skill set.
Your resume is your marketing tool for success. You need to be able to advertise your skills and ability to succeed with your prospective employer. The format and feel of your resume can either open doors or close them often this feeling can make people question why they didnt get the interview or thinking they are not qualified.
