Not all companies use ATS resume checkers, but a large percentage of medium to large businesses do. An ATS resume checker is commonly used by companies that receive a high volume of job applications, as it helps streamline the recruitment process. Smaller companies may not rely on ATS as much, but they are increasingly adopting this technology.
Using an ATS resume checker is beneficial even if you’re unsure whether a company uses ATS. By optimizing your resume with an ATS resume checker, you can ensure it’s well-structured and keyword-rich for any potential automated screening systems. Since ATS resume checkers help identify gaps in your resume, it's a good idea to use one whenever applying to larger corporations or job boards that use ATS.
