A back-end developer in Lyon does not look for a job in the same way as an administrative assistant transitioning in Finistère. However, the default filters of major platforms treat these two profiles almost identically. To obtain relevant results without spending hours sorting, one must understand how these tools work behind the scenes and adapt their online job search method to their actual situation.
Matching algorithms and automated job offer sorting
When a CV is submitted on a platform, an algorithm analyzes the document to extract keywords, job titles, and skills. This scoring determines which offers appear first in the result feed.
The concrete problem: if the CV uses “project management” and the offer mentions “project steering,” the matching may fail. One gains visibility by using the exact terms from the ads that interest them, directly in the CV and online profile.
Since the European AI regulation (AI Act) came into effect on August 1, 2024, matching and CV sorting tools are classified as high-risk. Specifically, platforms that use automated scoring must document their operations, manage biases, and provide for human oversight. For candidates, this means that these systems are not absolute black boxes: one has the right to know if a decision was made by an algorithm.
Article 50 of the AI Act, applicable since August 2, 2026, requires job sites using chatbots or AI-generated content to explicitly inform candidates. If a chatbot asks you pre-screening questions, the platform must indicate that it is an AI.
Setting up targeted job alerts by sector and location
Creating an account on three or four sites and waiting for email notifications is the most common method. It is also the least effective when alerts are poorly configured.
To obtain actionable results each morning without unnecessary noise, one can go through the Il était un Job portal, which groups offers by category and allows filtering by specific criteria right from the initial search.
The configuration that saves time relies on three settings:
- Restrict the geographical scope to a realistic radius relative to one’s home or an area of telework accepted by the employer, rather than leaving “entire France” as the default.
- Use precise job titles instead of generic terms: “HVAC technician” rather than “technician,” “IT recruitment officer” rather than “recruitment officer.”
- Exclude irrelevant keywords (internship, apprenticeship, volunteering) if looking for a permanent or fixed-term contract, to avoid half of the results being off-target.
Feedback varies on this point, but most platforms allow refining alerts after the first week of use, based on the offers received. Adjustments are made along the way.
Job search on LinkedIn and specialized professional networks
LinkedIn remains the main channel for executives and tech profiles. The “Open to Work” feature signals to recruiters that one is available, but it has a side effect: it increases the volume of untargeted solicitations.
A more effective approach is to activate this option only for recruiters (private mode) and to regularly publish content related to one’s field. A technical post or a field experience report generates more qualified contacts than a green badge on the profile picture.
For sectors where LinkedIn is less relevant (construction, hospitality, personal assistance), specialized platforms by sector offer a better matching rate. France Travail also provides a search engine with several hundred thousand offers, accessible without prior registration.
Online profile and consistency across platforms
Recruiters cross-check information between the received CV, the LinkedIn profile, and the application on the job site. Any inconsistency between dates or job titles raises a doubt. One should ensure that the three sources tell the same story, with the same periods and responsibilities.
Spontaneous online applications and company career sites
The offers published on platforms represent only a part of the market. Many companies recruit through their own career page, sometimes even before posting the ad on an aggregator.
Identifying target companies and checking their site directly allows access to less competitive positions. One can spot companies hiring in their sector through local news, fundraising announcements, or new site openings.
Spontaneous applications work better when addressed to an identified person (HR manager, direct supervisor) rather than a generic email box. A three-paragraph message explaining why this specific company and what concrete problem one can solve achieves a better response rate than a standardized cover letter.
Application tracking: a spreadsheet is enough
When applying on multiple platforms simultaneously, it is easy to lose track of what has been sent and to whom. A simple spreadsheet with five columns (date, company, position, channel, status) prevents duplicate follow-ups and forgetfulness.
Following up a week after sending remains the practice that generates the most positive responses, provided it is done through the same channel as the initial application.
The reflex to multiply registrations on ten job sites gives an illusion of activity. Three well-configured platforms, an up-to-date profile on a professional network, and direct monitoring of the career sites of targeted companies cover the vast majority of the visible market. The rest depends on the quality of each application sent, not on their volume.
