How JobFast works, in detail.

How a job is scored out of 10

Each listing is read by an AI model (Claude, built by Anthropic) together with your profile: your CV if you uploaded one, target roles, cities, experience level and the sectors you picked when signing up. It returns a whole-number score from 1 to 10 and a short explanation addressed to you.

• Seniority is a hard criterion. If the job asks for clearly more experience than you have, the score is capped at 6, and at 5 when the gap is large (leadership roles, 8+ years required).
• Scores of 9 and 10 are reserved for jobs where you meet the experience level asked for.
• Sectors matter. If you picked sectors, a job clearly outside them scores 4 at most; a job in one of your sectors gets a boost.
• When torn between two scores, the higher one wins. Scoring is deliberately a little generous so that an interesting job isn't filtered out.

A job counts as relevant from 6/10: that's the threshold at which JobFast prepares a CV and cover letter.

The score helps you sort, it doesn't decide for you. It can be wrong, especially when your profile is incomplete: the more precise your profile, the more accurate the score.

How the CV and cover letter are written

For each selected job, JobFast tailors your CV and writes a cover letter from two sources only: your background (uploaded CV and profile) and the text of the listing.

• The model is instructed never to invent a job, skill or graduation date that isn't in your profile.
• The CV reorders and rewords your experience to highlight what the job is looking for.
• The cover letter is written in the language of the listing, English or French.
• You can edit any document with a plain instruction (“shorter”, “mention my internship”) and download it as PDF or DOCX.

Always read your documents before applying: you're the best judge of what represents you.

Applications: you approve every one

The desktop agent opens the application form in a browser on your computer and fills it in with your details and documents. It stops before submitting: you review, fix anything you want and approve. No application is sent without your consent.

Where the listings come from

JobFast searches listings published publicly on job boards such as LinkedIn, Indeed, Welcome to the Jungle and HelloWork, based on your criteria (role, city, contract type). Every listing keeps its link to the original posting, where you apply. JobFast is not affiliated with any of these sites.

Public data on jobs, cities and salaries

When a JobFast page shows figures about an occupation, a local job market or a salary, they come from French public sources, cited on the page with their reference year and the date we retrieved them:

• France Travail (the French public employment service): the ROME 4.0 occupation directory (version 61, June 2026: job profiles, skills, job titles) and the 2026 BMO labour needs survey, which lists employers’ hiring plans by occupation and employment area;
• INSEE (national statistics office): 2024 average net private-sector salaries by occupation (all-employees database), in full-time equivalent, and town populations;
• DARES (Ministry of Labour): the FAP 2021 job family classification, which links ROME occupations to the BMO survey’s job families.

These figures are never extrapolated or filled in: a value hidden for statistical confidentiality is left out, and totals that exclude it are minimums. Salaries are averages, not medians. A page for a job in a given city is only published above a minimum number of hiring projects in its employment area, and only one city per area gets a page, so the same figures are not repeated from town to town.

Calculators (for example gross to net salary) apply the official rates in force and give an estimate, not a guaranteed amount.

Job profiles, glossary and examples: how they are written

Job profiles, example CVs, cover letters and interview answers, glossary definitions and their English versions are written by the JobFast team with the help of an AI tool, following one brief shared by every page.

• Figures are never typed by hand: salaries, hiring projects, skills and job titles come from the public sources described above and are shown with their source. The written text contains no statistics.
• Examples are templates: cover letters, CVs and interview answers are fictional and meant to be adapted; replace the parts in brackets with your own details.
• The glossary cites its official sources on every definition (service-public.fr, the French Labour Code, the Ministry of Labour). When a rule changes (minimum wage, durations, ceilings), we correct the definition and its update date.
• Every text goes through an automatic check before publication: length, typography, banned filler phrases and enough difference from related pages so the same page is not published twice.
• English pages follow the same rules and use the same figures as the French version.

These pages are for information and are not legal advice. For a specific situation, check the sources cited or ask a professional.

Articles and guides: our editorial policy

• Blog articles are written by the JobFast team to help job seekers with CVs, cover letters, interviews and the job search itself.
• When an AI tool helps with drafting, a team member reviews the text and checks facts and figures before publication.
• Every figure quoted links to its source.
• When an article mentions JobFast, it says so plainly: it's our product.
• The publication date, and the update date where relevant, appears at the top of every article.
