Optimal recruitment process: from search to hiring

Introduction

In an increasingly competitive job market, mastering each stage of the recruitment process has become a strategic issue for organisations of all sizes. According to a DARES 2025 study, the average cost of a failed recruitment represents between €30,000 and €50,000 for an SME, not counting the impacts on productivity and team cohesion. From defining the need to signing the employment contract, each phase must be thought through, structured and equipped with the right tools. This article provides you with a comprehensive guide to building an effective recruitment process that is compliant with legal requirements and fully digitalised.

Phase 1: Precisely define the need and prepare the ground

Before publishing any job offer, the preparation phase is decisive. A vague or incomplete job description is the leading cause of a high volume of unqualified applications, unnecessarily prolonging timeframes.

Build the job description and ideal candidate profile

The job description must go beyond simple job titles. It should include:

• Essential tasks with a clear order of priority

• Technical skills (hard skills) and behavioural skills (soft skills) required

• The expected level of experience and any required qualifications

• The salary range: according to Apec, job offers mentioning remuneration generate 40% more applications

• The organisational context: team size, tools used, working arrangements (hybrid, remote working)

This step ideally involves the operational manager, the HR director and, where relevant, one or two colleagues from the team in question.

Calibrate the sourcing strategy

The choice of distribution channels should be adapted to the profile you are looking for:

• General job boards (Indeed, Pôle Emploi / France Travail) for high-volume operational profiles

• LinkedIn Recruiter for senior and expert profiles

• Specialised sites (Cadremploi, Apec, Welcome to the Jungle) depending on the sector

• Internal referrals: 45% of CAC 40 companies report that internal referrals are their primary recruitment channel (PageGroup Barometer 2024)

• CV databases and ATS (Applicant Tracking System) to capitalise on past applications

A high-performing ATS allows you to centralise applications, automatically score them and reduce administrative processing time by 30 to 50%.

Phase 2: Attract and select the best candidates

The war for talent means paying as much attention to the attractiveness of the offer as to the rigour of the selection process.

Write an optimised job offer

A well-written offer is a lever for employer branding in its own right. Best practices include:

• A clear job title that is searchable on search engines (e.g. "Full Stack Developer React/Node.js – Permanent Paris")

• An attractive opening that highlights company culture and differentiating benefits

• Clear structure: bullet points, short paragraphs, information hierarchy

• Explicit mention of the recruitment process: number of interviews, timelines, points of contact

According to a LinkedIn 2024 study, offers describing the selection process receive a 25% higher application rate.

Implement a structured pre-selection process

To avoid bias and ensure fairness, the pre-selection process must be formalised:

• CV screening based on objective criteria: education, experience, key skills

• 15 to 20-minute telephone or video interview to validate motivation, availability and salary expectations

• Competency tests: case studies, technical tests, role-playing scenarios

• Structured face-to-face interview with the manager and HR representative

The STAR method (Situation, Task, Action, Result) is recommended by the American Psychological Association as one of the most predictive of future performance.

Phase 3: Evaluate and choose the right candidate

Structure interviews to reduce cognitive biases

Recruitment biases (halo effect, similarity bias, stereotypes) are documented by occupational psychology research and can lead to discrimination punishable under article L1132-1 of the Labour Code. To limit them:

• Use a standardised evaluation grid shared between all recruiters

• Train managers in behavioural interviews

• Have multiple assessors with different perspectives involved (panel interview)

• Document rejection and selection criteria at each stage

Make the decision and make the offer

After the evaluation phase, the decision must be collegial and documented. The employment offer (or offer letter) should specify:

• The exact job title and conventional classification

• Gross remuneration, any variable elements and benefits (health insurance, meal vouchers, days off)

• The start date and the duration of the probation period

• The expected time for the candidate to respond

This step marks a crucial transition: from the selection process to the formalisation of the employment contract.

Phase 4: Finalise hiring and digitalise the contracting process

From the employment promise to the employment contract

Since the Macron ordinance of 2017 (n°2017-1387), the distinction between unilateral employment promise and employment contract offer has been clarified by the Court of Cassation. An employment promise amounts to a contract if it specifies the job, the start date and the remuneration — revocation of it entitles the person to damages.

A permanent employment contract in France is not subject to any mandatory legal formality except in exceptional cases (part-time, fixed-term contracts, apprenticeships), but the applicable collective agreement may require a written document. However, it is in all cases strongly recommended to formalise it in writing.

Dematerialise the signing of the employment contract

Electronic signature of the employment contract represents a considerable saving of time and reliability. It allows you to:

• Eliminate postal delays and printing errors

• Guarantee the authenticity and integrity of the signed document

• Centralise proof of signature in a digital safe

• Accelerate onboarding: the employee can sign their contract from their phone before their first day

For HR contracts, a signature compliant with eIDAS regulations is legally equivalent to a handwritten signature provided that the advanced signature level (AES or QES) is used.

The use of an HR document generation solution coupled with an electronic signature solution allows you to produce contracts compliant with the collective agreement in a few minutes, then send them for signature without re-entry.

Structure onboarding to anchor the new recruit

Recruitment does not stop at contract signing. Onboarding is a critical phase: according to the Society for Human Resource Management (SHRM), structured onboarding improves 3-year retention by 82%. Best practices include:

• Sending the digital welcome pack before day one (welcome booklet, tool access, first week schedule)

• Designating an internal mentor or contact person

• Formalised follow-up points at 1 month, 3 months and end of probation period

• Dematerialised signing of onboarding documents (internal regulations, IT policy, etc.) via the integrated HR solution

Phase 5: Measure recruitment performance and continuously improve

Essential recruitment KPIs

An optimal recruitment process is measurable. Key indicators to track are:

• Time-to-hire: average time between job posting and offer acceptance (French benchmark: 35 to 50 days according to Talent Board 2025)

• Time-to-fill: time until effective start date

• Quality of hire: performance of the new colleague at 6 months and 1 year

• Offer acceptance rate: indicator of the competitiveness of your value proposition

• 90-day retention rate: reveals the quality of onboarding

• Cost per recruitment: total budget (sourcing, ATS, HR time, integration) divided by the number of hires

Integrate a continuous improvement approach

Regular analysis of these KPIs makes it possible to identify bottlenecks: pre-selection phase that is too long, high rate of withdrawal between offer and signature, gap between the recruited profile and the manager's expectations.

The most high-performing HR teams organise recruitment retrospectives after each process, involving the manager, the recruiter and, where possible, the selected candidate — or even rejected candidates via candidate experience surveys.

Legal framework applicable to recruitment contracting

Labour Code and contract law

The formalisation of recruitment is governed by several legal provisions that are essential to understand.

Article L1221-1 of the Labour Code provides that the employment contract is subject to the rules of ordinary law. Article L1221-3 requires that fixed-term contracts and part-time employment contracts be concluded in writing, on pain of requalification.

Articles 1366 and 1367 of the Civil Code (from ordinance n°2016-131 of 10 February 2016 reforming contract law) establish the legal framework for electronic signatures in France: electronic writings have the same probative force as paper writings provided that the identity of the author can be properly identified and the document is retained under conditions guaranteeing its integrity.

eIDAS Regulation and signature levels

European Regulation eIDAS n°910/2014 (Electronic IDentification, Authentication and trust Services) distinguishes three levels of electronic signature:

• SES (Simple Electronic Signature): sufficient for low-risk legal documents

• AES (Advanced Electronic Signature): recommended for employment contracts, guarantees identification of the signatory and document integrity

• QES (Qualified Electronic Signature): equivalent to handwritten signature under article 25(2) of eIDAS, required for authenticated acts

For employment contracts, AES is generally sufficient and legally robust. The ETSI EN 319 132 (XAdES) and ETSI EN 319 122 (CAdES) standards define the technical formats of advanced electronic signatures compliant with eIDAS.

GDPR and candidate data protection

The processing of candidates' personal data is subject to the General Data Protection Regulation (GDPR) n°2016/679. The main obligations include:

• Legal basis: the legitimate interest of the employer (article 6(1)(f) GDPR) or explicit consent for sensitive data

• Retention period: maximum 2 years for data of unsuccessful candidates according to CNIL (French Data Protection Authority) recommendations (decision n°2016-186)

• Right of access and erasure: candidates can request access to their data and its deletion

• Processing register: recruitment must be included in the company's processing register (article 30 GDPR)

In the event of a data breach involving candidate personal data (CV leak, unauthorised access to the ATS), the company must notify the CNIL within 72 hours in accordance with article 33 of the GDPR.

Non-discrimination and employer obligations

Article L1132-1 of the Labour Code prohibits any discrimination in recruitment based on origin, sex, age, disability, religion or any other protected criterion. Rigorous documentation of the selection process is the best protection in the event of employment tribunal proceedings.

Use cases: digitalised recruitment in practice

Scenario 1: An industrial SME of 150 employees reduces time-to-hire by 40%

An industrial SME managing around fifty recruitments per year faced average delays of 65 days between publishing offers and signing contracts. The main bottleneck? Postal delivery of contracts and back-and-forth exchanges for corrections and signatures.

By implementing an electronic signature solution integrated with its ATS, the company was able to:

• Reduce the contracting timeframe from 12 days to less than 48 hours

• Eliminate 100% of postal mailings of contracts and amendments

• Centralise proof of signature in a compliant digital safe

• Improve candidate experience, with onboarding satisfaction increasing from 62% to 84%

Overall time-to-hire was reduced by 40%, representing an estimated saving of €15,000 per year in recruitment costs (temporary staffing, loss of productivity on the vacant position).

Scenario 2: An HR consulting firm externalises contracting for its clients

An HR consulting firm supporting twenty SME clients in their recruitment had to manage dozens of employment contracts simultaneously, with different collective agreements depending on the sectors.

By adopting an AI-powered contract generator coupled with a multi-company electronic signature platform, the firm was able to:

• Generate contracts compliant with each collective agreement in less than 5 minutes, compared to an average of 45 minutes previously

• Offer its clients a dedicated portal to monitor the status of signatures in real time

• Reduce contractual errors by 70% thanks to standardised and verified templates

• Charge for a value-added digital contracting service, increasing its average client basket by 18%

Scenario 3: A group of private clinics secures the recruitment of healthcare personnel

A private hospital group of approximately 600 beds recruits over 200 healthcare professionals (nurses, nursing assistants, doctors) each year. Verifying qualifications, professional orders and signing confidentiality clauses represented a considerable administrative burden for the HR team.

By integrating an electronic signature solution compliant with AES level, the group was able to:

• Dematerialise 100% of contracts and amendments for permanent and temporary recruitments

• Reduce the average contracting timeframe from 8 days to less than 24 hours

• Guarantee traceability and integrity of all signed documents, an imperative in a sector subject to frequent regulatory inspections

• Save the equivalent of 0.8 FTE on administrative contracting tasks, reassigned to supporting new recruits

Conclusion

An optimal recruitment process does not happen by chance: it is built step by step, from precisely defining the need to structured onboarding, via rapid and secure contracting. Digitalising the signature phase represents one of today's most effective levers for reducing time-to-hire, improving candidate experience and ensuring legal compliance of hires.
