Optimal recruitment process: from search to hiring

Introduction

In an increasingly competitive job market, mastering each step of the recruitment process has become a strategic priority 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 impacts on productivity and team cohesion. From defining the need to signing the employment contract, each phase must be carefully planned, structured and equipped with the right tools. This article offers you a comprehensive guide to building an effective recruitment process that complies with legal requirements and is fully digitalised.

Phase 1: Precisely define the need and prepare the ground

Before publishing any job advert, the preparation phase is critical. A vague or incomplete job description is the leading cause of a high volume of unqualified applications, unnecessarily extending timelines.

Building the job description and ideal candidate profile

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

• Essential duties with a priority order

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

• Expected experience level and any prerequisite qualifications

• Salary range: according to Apec, job postings mentioning remuneration generate 40% more applications

• Organisational context: team size, tools used, work arrangement (hybrid, remote)

This stage ideally involves the operational manager, 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 being sought:

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

• LinkedIn Recruiter for senior and expert profiles

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

• Internal referral: 45% of CAC 40 companies state that referral is their primary recruitment channel (PageGroup Barometer 2024)

• CV databases and ATS (Applicant Tracking System) to build 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 requires paying as much attention to the appeal of the job offer as to the rigour of the selection process.

Write an optimised job advertisement

A well-written job offer is a brand reputation lever in its own right. Best practices include:

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

• An attractive introduction 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, contacts

According to a LinkedIn 2024 study, job postings describing the selection process achieve a 25% higher application rate.

Implement a structured pre-selection process

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

• CV screening using objective criteria grid: education, experience, key skills

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

• Skills tests: practical cases, technical tests, simulations

• Structured interview in person 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 bias

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

• Use a standardised evaluation grid shared among all recruiters

• Train managers in behavioural interviews

• Involve multiple evaluators with different perspectives (panel interview)

• Document selection and rejection criteria at each stage

Make the decision and formulate the offer

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

• The exact job title and conventional classification

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

• Start date and probationary period duration

• Expected response timeframe from the candidate

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

Phase 4: Finalise hiring and digitalise contract execution

From employment promise to employment contract

Since the Macron decree of 2017 (n°2017-1387), the distinction between unilateral employment promise and employment contract offer has been clarified by the Court of Cassation. The employment promise is equivalent to a contract if it specifies the job, the start date and remuneration — its revocation gives the right to damages.

The permanent employment contract (CDI) is not subject to any mandatory legal formalities except in exceptional cases (part-time, fixed-term, apprenticeship), but the applicable collective agreement may require written form. In all cases, it is strongly advisable to formalise it in writing.

Digitalise the signature of the employment contract

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

• Eliminate postal delays and printing errors

• Guarantee the authenticity and integrity of the signed document

• Centralise evidence of signature in a digital safe

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

For HR contracts, a signature compliant with the eIDAS regulation is legally equivalent to a handwritten signature as long as the advanced signature level (SEA or QES) is used.

The use of a document generator combined 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 doesn't stop at contract signature. 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 guide, tool access, first week schedule)

• Designating an internal mentor or reference person

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

• Digitalised signature of onboarding documents (staff handbook, IT policy, etc.) via the integrated HR solution

Phase 5: Measure recruitment performance and improve continuously

Essential recruitment KPIs

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

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

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

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

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

• 90-day retention rate: indicator of onboarding quality

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

Integrate a continuous improvement approach

Regular analysis of these KPIs allows you to identify bottlenecks: pre-selection stage taking too long, high dropout rate between offer and signature, gap between recruited profile and manager's expectations.

The highest-performing HR teams organise recruitment retrospectives after each process, involving the manager, recruiter and, where possible, the successful candidate — even unsuccessful candidates through candidate experience surveys.

To go further in digital HR transformation, our guide explains how to digitalise the entire lifecycle of HR documents, from contract to amendments to termination documents.

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 states that the employment contract is subject to the rules of general law. Article L1221-3 requires fixed-term contracts and part-time employment contracts to 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 written documents have the same probative force as paper written documents as long as the identity of the author can be properly identified and the document is preserved in conditions guaranteeing its integrity.

eIDAS Regulation and signature levels

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

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

• SEA (Advanced Electronic Signature): recommended for employment contracts, guarantees signer identification and document integrity

• SEQ (Qualified Electronic Signature): equivalent to handwritten signature under Article 25(2) of eIDAS, required for authentic acts

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

GDPR and protection of candidate data

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

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

• Data retention period: maximum 2 years for data on unsuccessful candidates according to CNIL recommendations (deliberation n°2016-186)

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

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

In the event of candidate personal data breach (CV leak, unauthorised ATS access), the company must notify 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 recruitment discrimination based on origin, sex, age, disability, religion or any other protected criterion. Rigorous documentation of the selection process provides the best protection in case of employment tribunal proceedings.

Usage scenarios: 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 job postings and signing contracts. The main bottleneck? Postal sending of contracts and back-and-forth exchanges for corrections and signatures.

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

• Reduce contracting time from 12 days to less than 48 hours

• Eliminate 100% of postal sending of contracts and amendments

• Centralise signature evidence in a compliant digital safe

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

Overall time-to-hire was reduced by 40%, representing estimated savings of €15,000 per year on recruitment costs (interim coverage, productivity loss from vacant position).

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

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

By adopting an AI-powered contract generator combined 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 45 minutes on average previously

• Offer its clients a dedicated portal to track signature status in real time

• Reduce contractual errors by 70% through standardised and verified templates

• Invoice a digital contracting service with added value, increasing its average client basket by 18%

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

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

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

• Digitalise 100% of contracts and amendments for permanent and temporary recruitment

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

• Guarantee traceability and integrity of all signed documents, essential 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 doesn't happen by chance: it is built step by step, from precisely defining the need to structured onboarding, passing through quick and secure contracting. The digitalisation of the signature phase represents one of the most effective levers today to reduce time-to-hire, improve candidate experience and guarantee legal compliance of hires.
