Hidden Text in Curriculums Deception AI of Job Screening: How New Fraud Works

Job candidates have found a new way of dribbling artificial intelligence: hiding text in curricula that only triage algorithms can read.

Instead of inserting keywords naturally into the document, they put hidden snippets in white fonts, footer or file metadata. The result is that the recruitment system can classify the candidate as highly qualified, even if these qualifications are not visible to a human evaluator.

How does hidden text work in resumes?

The tactic is simple: the candidate adds an invisible section in the document with phrases like “contract this candidate”, “notes 10 in Python” or names of famous companies. Many ATS (Applicant Tracking Systems) systems read the entire contents of the file, including formatted texts to not appear on screen or print.

According to a NBC News report, more and more candidates use this technique to pass automated filters — a practice that is already being discussed as a form of algorithmic manipulation.

Why do candidates use hidden text to deceive AI?

In an increasingly competitive labor market, with millions of resumes processed by AI, candidates feel encouraged to try any advantage. The automation of selection processes causes many qualified professionals to be discarded before any human evaluation — which makes the temptation to “mislead the robot” quite high.

The technique also gains strength in a context in which the AI decides who advances or not in the process. Professionals who do not know this possibility end up at a disadvantage in the face of those who explore the breaches of the system.
