Hiring algorithms: Where automation enters the funnel

It's not just one 'bot'. It's a chain of automated decisions. Expanding our ATS myths into screening systems education.

The System

Compounding Bias

Bias isn't isolated; it amplifies as candidates move from ad targeting to screening to ranking.¹

The Automated Funnel

Automation isn't just "scanning keywords" at the end. It starts before you even see the job ad.¹

Automation risk cascade

Sourcing

Ad Delivery

Old ads only shown to certain demographics

Screening

Resume Parsing

Non-standard formats parsed incorrectly

Selection

Ranking

Bias against gaps or 'non-target' schools

Interview

AI Scoring

Standardized questions with biased grading

Bias compounds downstream

Each automation handoff can amplify bias from the previous stage. The human interview is where the most damage occurs.

Bias compounds across stages

Most advice focuses on the "Resume Parsing" stage. But predictive ranking algorithms and ad delivery algorithms also play a huge role. If an ad platform decides you aren't the "target demographic," you might never see the role.¹

We can't fix the ad servers, but we can ensure that once you are in the pipeline, your data is structured so clearly that no parser can misunderstand your qualifications.

The 'Hidden' Funnel

Recruiter lens: understanding the machine helps you write with more structure and less fluff.

Definition: exposure bias

Exposure bias happens when the system decides who sees a job or who is surfaced first. Candidates who are not surfaced never get evaluated.¹

FAQ

Where does bias enter the hiring funnel?

Bias can enter at ad delivery, eligibility screening, ranking, and human review. The earlier it enters, the more it compounds.

Can a resume fix algorithmic bias?

No. A resume can only reduce avoidable noise, not systemic bias.

What should candidates do?

Use clear structure and keywords so automated systems and humans can read the resume without friction.
