Step 1: the file is read
Before anything is judged, the system extracts text from your file and sorts it into fields. If a table, column or header box scrambles that step, everything after it works from a distorted version of your resume. This is the stage you can inspect most directly, by looking at the text recovered from your own file.
Step 2: the wording is compared to the role
Automated screening compares the language in your resume with the language in the posting: required skills, tools, titles and responsibilities. It rewards specific terms used in context and gives little credit for a keyword list disconnected from any work. A close match on the terms the posting repeats matters more than covering every term once.
Step 3: candidates are ranked or filtered
Depending on the employer, the result is a ranked list, a set of knockout questions such as work authorisation or a required certification, or simply a searchable database that a recruiter queries later. Fully automatic rejection on a keyword score is less common than people fear, but being hard to find in a recruiter's search is common and has the same effect.
Step 4: a person decides
In nearly every process a human reads the shortlist. That is why a resume has to work twice: parseable and relevant to a system, then specific and credible to a person who is deciding in seconds whether to keep reading.
