Optimal hiring process: from sourcing to engagement

Recruiting the right colleague is one of the most strategic decisions for a company. Yet, according to a LinkedIn Talent Trends study (2025), 68% of HR managers believe their hiring process still contains time-consuming manual steps that weaken the candidate experience. Optimising this process, from defining the need through to signing the employment contract, has become a competitive imperative. This article describes each key phase, the tools to deploy, legal best practices and how digitalisation — particularly via electronic signature for HR — concretely transforms talent engagement.

Define the need and build the job profile

Before any job posting is circulated, a rigorous analysis of the need conditions the quality of applications received.

Map the position and required competencies

The job description is the foundation of recruitment. It must specify:

• Main responsibilities and their weighting in working time.

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

• Hierarchical positioning, internal and external interfaces.

• Employment conditions: type of contract (permanent, fixed-term, apprenticeship), salary level, workplace, possible remote working.

A well-written job description reduces unnecessary applications by 30 to 40%, according to APEC benchmarks 2024. It also constitutes a legal reference document in case of dispute over the job definition, particularly in the event of contract requalification.

Validate resources and recruitment budget

The cost of a failed recruitment is estimated at between 3 and 6 months gross salary depending on the level of the position (source: Deloitte Human Capital Trends 2024). You should therefore plan ahead: agency fees, job board subscriptions, internal time mobilised and onboarding costs. A forecast dashboard incorporating these elements allows HR to defend its budget with the finance department.

Source and attract the best candidates

The sourcing phase determines the quality of the available talent pool.

Choose appropriate distribution channels

Channels fall into three main categories:

• General job boards (Indeed, HelloWork, Pôle Emploi): large volume, moderate cost, relevant for operational profiles.

• Professional social networks (LinkedIn, Welcome to the Jungle): essential for senior profiles and hard-to-fill roles.

• Internal referral: according to an SHRM study (2025), referral recruits are 55% faster and show a retention rate 20 to 24% higher at 24 months.

Companies combining at least three channels simultaneously reduce average time-to-fill by 25%.

Nurture your employer brand

Employer brand directly influences the conversion rate of applications. Glassdoor indicates that 75% of active candidates check an employer's reputation before applying. A well-maintained career page, authentic team testimonials and consistent LinkedIn presence help attract culturally aligned profiles — reducing the risk of early turnover.

Select and evaluate candidates

Selection is the most time-consuming step if not properly structured.

Implement an objective evaluation grid

Using a structured scorecard allows objective comparison of candidates on the same weighted criteria. This practice also meets the non-discrimination requirements imposed by French law (articles L.1132-1 et seq. of the Labour Code). Each evaluator scores independently, then synthesis is done in committee, limiting confirmation bias.

Conducting interviews and assessments

Structured interviews based on past situations (STAR method: Situation, Task, Action, Result) is recognised as the format offering the best predictive validity of future performance (coefficient r ≈ 0.51 according to the Schmidt & Hunter meta-analysis, reviewed in 2025). Psychometric tests and simulation exercises usefully complement evaluation for high-stakes positions.

Verify references and qualifications

Verification of professional background (reference checking) is legal in France provided the candidate is informed beforehand. It allows validation of the consistency of the stated career path. According to a HireRight survey (2024), 85% of employers detected at least one inaccuracy in a CV during the past year.

Formulate the offer and negotiate employment terms

Once the candidate is selected, the offer phase legally engages the company if sufficiently precise.

Write a solid employment promise

Since the Court of Cassation ruling of 21 September 2017, the unilateral promise of an employment contract constitutes a genuine contract upon receipt by the candidate. It must mention: the identity of the parties, the position, remuneration, start date and workplace. Any subsequent withdrawal engages the employer's liability for wrongful breach.

The AI-powered contract generator from Certyneo enables production of compliant employment promise templates and contracts, reducing drafting errors and accelerating signature.

Negotiate salary and benefits

Salary transparency is progressing in Europe with Directive 2023/970/EU on pay equality, the transposition of which into French law is expected by June 2026. Employers must prepare to communicate salary ranges in their job postings. A documented remuneration policy protects the company against discrimination claims.

Finalise engagement: from contract to electronic signature

The final step — contractual formalisation — is often the slowest in traditional processes. A printed contract, handwritten signature, scanned and filed can take 3 to 7 working days depending on the geographic constraints of the parties.

Digitalise the employment contract

Electronic signature of the employment contract is fully recognised by French law (article 1366 of the Civil Code) and eIDAS Regulation No. 910/2014. A signature of advanced or qualified level offers probative force equivalent to that of a handwritten deed, while reducing signature time to less than 15 minutes on average.

Organise digitalised onboarding

Engagement does not stop at contract signature. Digitalised provision of the welcome booklet, internal rules, IT charter and applicable collective agreements completes the hiring file without printing or postal sending. Modern HR solutions integrate these flows into a fully digital onboarding journey, improving employee experience from day one.

Archive in compliance with GDPR and the Labour Code

Archiving electronically signed employment contracts must respect legal retention periods: 5 years after the end of the contract for payslips and contractual documents (article D.3243-4 of the Labour Code). Electronic signature in business also requires guaranteeing the integrity and traceability of archived documents, in accordance with GDPR requirements on protection of employee personal data.

Legal framework for the hiring process and electronic signature

Labour law and non-discrimination

The hiring process is governed by the French Labour Code, notably articles L.1132-1 to L.1132-6 which prohibit any discrimination based on origin, sex, age, religion, health status, sexual orientation or union membership. Any job posting or evaluation grid implicitly mentioning these criteria exposes the employer to criminal sanctions (up to 3 years imprisonment and €45,000 fine).

The employment promise, since the Court of Cassation rulings of 21 September 2017 (No. 15-20.740), is subject to the rules of unilateral contract promise (article 1124 of the Civil Code), engaging the promisor from the moment the candidate exercises the option.

Legal validity of electronic signature

Article 1366 of the Civil Code establishes the principle of equivalence between handwritten and electronic signature, provided the latter identifies the signatory and guarantees the link with the signed deed. Article 1367 specifies the conditions of reliable electronic signature.

Regulation eIDAS No. 910/2014 (currently being updated to eIDAS 2.0) establishes three signature levels: simple (SES), advanced (AES) and qualified (QES). For ordinary employment contracts, an advanced signature complying with ETSI EN 319 132 standards is generally sufficient. Qualified signature remains recommended for high-stakes documents (severance agreement, settlement).

Protection of personal data

GDPR No. 2016/679 applies from CV collection onwards. The employer must inform candidates of data processing (article 13 GDPR), limit retention of unsuccessful applications to maximum 2 years (CNIL recommendation, decision 2022), and guarantee security of stored data. In case of HR data breach, notification to CNIL within 72 hours is mandatory (article 33 GDPR).

Archiving and probative value

Archiving electronically signed contracts must ensure their integrity throughout the legal retention period. Compliant solutions rely on qualified timestamps (article 41 eIDAS) and certified digital safes NF Z42-020. The audit trail generated by the signature platform constitutes evidence admissible before labour courts.

Concrete use scenarios

A 150-employee industrial SME accelerates seasonal recruitment

An SME specialising in mechanical component manufacturing recruits between 30 and 50 production operators annually in fixed-term seasonal contracts. Before digitalisation, the hiring process required printing 6 documents per file, postal sending in duplicate, then waiting for signed return — an average delay of 5 to 8 working days per contract. By deploying an advanced electronic signature solution integrated with their HRIS, the company reduces this delay to less than 2 hours. The rate of candidate withdrawal during the contractual phase decreases by 40%, because the experience is fluid and mobile-friendly. The estimated gain is 120 hours of HR work annually on CDD document management alone.

A 400-employee digital services group secures senior hiring

A digital transformation consulting company regularly recruits senior profiles (cloud architects, project managers, consultants). Remuneration packages include confidentiality, non-compete and profit-sharing clauses. The legal department requires qualified signature level (QES) for these sensitive contracts. By integrating Certyneo into its process, the HR team automatically generates contracts from templates validated by lawyers, sends the complete file to the future employee and obtains a qualified signature with online identity verification. Finalisation time drops from 7 days to 48 hours, and automatic archiving ensures GDPR compliance without manual intervention. The HR Director estimates savings of €15,000 annually on management, printing and courier fees.

A restaurant franchise network standardises onboarding

A network comprising sixty outlets employs several hundred employees on permanent and apprenticeship contracts. Geographic dispersion made collecting signed contracts particularly chaotic: frequent delays, lost documents, inability to start payroll without signed contract. By adopting a fully digitalised hiring flow — from employment promise to provision of internal rules — the network harmonises practices between franchisees, reduces payroll start delays by 4 days on average and guarantees the head office real-time visibility on the status of hiring files in each establishment.

Conclusion

Optimising the hiring process, from job definition through contract signature, is not merely an operational efficiency matter: it is a strategic issue for attracting, convincing and engaging the best talent before your competitors. Each step — targeted sourcing, structured evaluation, legally sound offer and rapid formalisation — contributes to reducing delays, legal risks and hidden recruitment costs.

Electronic signature constitutes the final link that transforms a still often manual process into a fluid, secure and compliant journey. Certyneo supports HR teams in this transition with an easy-to-deploy solution, eIDAS compliant and adapted to all recruitment volumes.
