An ATS (Applicant Tracking System) is recruitment software that receives, stores, and sorts applications before a recruiter reviews them. If you are looking for an apprenticeship, an internship, or a first job, your CV often goes through this tool first: understanding what an ATS is helps you avoid silent rejections.

Definition: what is an ATS?

ATS = Applicant Tracking System.

Its role:

  1. Centralize CVs submitted for a role (careers site, job board, referral).
  2. Analyze the text (skills, keywords, years of experience based on detected fields).
  3. Rank or filter profiles for the next step (shortlist, interview, rejection).

It is not a recruiter: it is a technical step between your submission and human review.

How an ATS reads your CV

Most ATS tools extract text from your file (often PDF or Word). They look for:

  • the job title or headline;
  • sections (experience, education, skills, projects);
  • keywords from the job posting (tools, languages, methods).

A CV with multiple columns, icons without text, or a scanned image PDF can be misinterpreted. The content is there, but the bot does not "see" it correctly.

With AltCV, you start from a structure already designed for readability: clear sections, skill lists, clean PDF export. You reduce the risk of a CV that is unreadable for an ATS filter.

Why it matters for students

In an apprenticeship or internship, you have little long professional experience: the ATS mainly compares keywords, job titles, and consistency with the ad. A generic CV sent everywhere often scores low.

Concrete levers:

  • reuse the vocabulary from the posting (without lying about your skills);
  • highlight projects and internships relevant to the role;
  • keep a simple layout (single column, short bullet points).

AltCV does not create fake backgrounds: it reorders and rephrases your real profile to match each ad. You no longer have to rewrite everything by hand for every application.

ATS and recruiter: who decides?

The ATS prepares the sorting; the recruiter often keeps the final decision, especially for profiles already shortlisted. But if your CV is poorly ranked or hard to find, you sometimes never reach the human step.

That is why a CV targeted per posting beats a single file for every company.

What to do in practice?

  1. Read the posting and note the required skills you actually have.
  2. Adapt title, projects, and skills to the role.
  3. Export a readable PDF (selectable text, not a photo of a CV).
  4. Track your application (date, status, version sent).

With AltCV, steps 2 through 4 happen in one place: generation aligned with the posting, export, then tracking linked to the right CV. You avoid sending the wrong PDF to the wrong company.

In summary

  • ATS = software that sorts and ranks applications before the recruiter.
  • It mainly reads structured text and keywords aligned with the posting.
  • Student / apprenticeship: projects and internships count if they are presented well.
  • AltCV helps you produce a targeted CV readable by the ATS, without inventing experience.

Frequently asked questions

What does ATS mean in recruitment?
ATS stands for Applicant Tracking System. It is the tool that centralizes CVs received for a job posting and helps sort them before a recruiter reads them.
Do all companies use an ATS?
Not all of them, but it is very common once application volume grows (large companies, platforms, agencies). Even an SMB may use an ATS through a job board or HR provider.
Can an ATS reject my CV without a human?
Yes: your CV may be poorly read (image PDF, complex layout) or poorly aligned with the job posting, and therefore ranked low without a recruiter ever opening it. That is why a clean, targeted CV matters.
How does AltCV help with an ATS?
AltCV structures your real profile, aligns vocabulary with the job ad, and exports a readable PDF without inventing experience. You generate one version per posting rather than a generic CV.
