Employers are often bombarded with more resumes than they need, so when the resume looks disorganized with misaligned text or alignment inconsistencies, it discourages the resume reviewer from wanting to review further. Also, with more employers relying on applicant tracking systems (ATS) to help filter out the top resumes of relevance, formatting is critical to ensure these systems can read the content.
When you learned the English language, you learned to read and write from left to right, so it makes sense to always have your content on the resume left-justified. This prevents irregular spacing and uncomfortable reading. The only time you should consider a justified, or centered, format is for your name, contact information and summary of qualifications. These are key elements in your resume that may deserve different formatting than the rest of your content.
Applicant Track System Benefits
When applying for any job, it's important that you follow the application instructions carefully, particularly when it comes to resume formatting. Many large employers use an ATS to filter out the top resumes that match the job before they go to the reviewer. Elements such as tables and text boxes should be avoided because content within these elements can't be read by the ATS. When you simplify things by using a left-justified alignment throughout your resume, it will still look organized in case formatting changes occur when the employer opens your document with a different software program than yours.
