What is an ATS? What happens to your application before a human sees it

When you apply for a job, your CV usually reaches a piece of software first: an applicant tracking system, or ATS. Companies receive far more applications than an inbox can handle, so they use these systems to collect applications in one place, keep them organised, and track every candidate through the hiring process.

It's a common mistake to think of the ATS as a wall between you and the employer. In practice it's the opposite: it is what keeps your application from getting lost. Unlike a CV buried in an email attachment, an application in a tracking system is recorded, attached to a specific job, and visible at every stage.

What happens after you apply

Details vary by company, but the typical flow looks like this:

1. Intake: Your application is linked to the job posting; your contact details and CV are stored.
2. Parsing: The system extracts structure from your CV — experience, education and skills become separate fields. This step is also why heavily designed CVs sometimes get read incorrectly.
3. Screening questions: Some postings ask short questions at apply time (work authorisation, years of experience). Your answers are checked against rules the employer defined.
4. Evaluation and ranking: Modern systems can score applications against the job's criteria, so the hiring team starts with the strongest-looking matches.
5. Pipeline stages: Applications move through stages — review, interview, offer. The "we received your application" email you get is usually the first visible sign of this flow.

Three common myths

"The ATS auto-rejects CVs." Rule-based knockouts only apply where the employer explicitly defined a condition (a mandatory licence, for example). In well-built systems, rejection is a human decision; the software sorts and suggests.

"The more keywords, the better." Keyword stuffing can break parsing and looks bad to the human reader who eventually opens your CV. The right move is to show the skills from the posting where you actually used them — inside your work experience.

"If there's a system, no human is involved." The point of the system is the reverse: it frees the hiring team from sifting through the pile so they can spend time actually talking to candidates.

Writing for the system and the human at once

• Keep the layout simple. One column, standard headings (Experience, Education, Skills), a readable font. Tables and text boxes can confuse parsing.
• Prefer PDF unless the posting asks otherwise — a text-based (not scanned) PDF is the safest format for both software and people.
• Tailor to the posting. Make sure the core requirements in the ad have a visible counterpart in your CV. Never add a skill you don't have.
• Make dates and titles unambiguous. "Senior Sales Specialist — since January 2022" beats vague phrasing, for parsing and for scoring alike.
• Take screening questions seriously. Short answers are part of the evaluation; don't rush through them.

Transparency matters

Not all systems are equal. Some treat evaluation as a black box; others — as Kariora does on the employer side — show the hiring team the reasoning behind every score: which criteria are met and which are missing. For candidates, that means your application isn't reduced to a bare number; it can be reviewed criterion by criterion, and the final decision always belongs to a person.
