This means that the computer kicks it out of the system. It is never forwarded to a hiring manager. The people at the company don't even know you exist.
Applicant Tracking Systems (ATS) have become a true thorn in the side of job seekers. You can literally send your resume out to 100's of jobs and NEVER hear anything back.
This happens because your resume isn't being delivered to a human being. It's being scanned by a computer system.
The ATS scan resumes for everything from format, margin size, years of experience, education, and relevant keywords. Miss the mark on even one of those things and your resume is rejected.
We look forward to working with you and would like to wish you the best of luck with your professional endeavors!
