Functional format is best for those who are switching their career or have large employment gaps on their resume. In this format, you dont have to list the joining or resigning dates of the previous employments. Functional format will hide your employment gaps or your job switching.
Chronological format is most commonly used. It is best format for recent graduates and fresher applicants. The details in such CV are presented in the bullet-ed points and are categorized into different sections. The skills are generally listed after the career objective and before professional experience details as fresher applicant will not have any eye catching experience details to grab the attention of the employer.
Make sure to have contact information on every page Nothing is worse than having an amazing resume and forgetting to add in contact information. Do not assume that if your resume is two pages that they will stay together either. Put your name and contact info at the top of every page and add in page numbers for a more professional look as well.
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.
Use good quality paper and a laser printer Dont skimp on paper quality with your resume it leaves a bad impression. Poor quality paper creases and wrinkles easier. Use a laser printer to make sure your resume doesnt smudge or smear. Always use white paper for easier photocopying and avoid color in your resume. Black and white is the way to go.
