Applicant Tracking Systems (ATS) are crucial in the hiring process to filter and screen job applications.
Using a PDF format for resumes has advantages like preserved formatting and professional appearance, but it may lead to parsing errors and compatibility issues with ATS.
When applying through a company's website or emailing a recruiter, a PDF resume is often preferred, but for major job boards using ATS, a Word document may be more suitable.
To make a PDF ATS-friendly, use standard fonts, avoid multiple columns and excessive graphics, and ensure the text is selectable.
