The optimal recruitment process: from application to salary

Recruitment is one of the most strategic — and most time-consuming — processes in a company's life. According to a 2024 LinkedIn Talent Solutions study, the average time to fill a position in France is 44 days, with direct and indirect costs that can reach €3,000 to €8,000 per recruitment depending on the size of the organisation. Faced with these challenges, optimising every stage — from drafting the job posting to delivering the first payslip — is no longer a luxury but a competitive necessity. The digitalisation of the HR journey, notably electronic signature for HR, plays a central role here. In this guide, we detail the key phases of an effective recruitment process and the concrete levers to accelerate them.

Phase 1 — Define the need and build the job posting

Job analysis: the foundation of successful recruitment

Before publishing anything, the HR team must co-create a precise job description with the operational manager. This step, often rushed, is nonetheless decisive: a vague job description generates unsuitable applications, lengthens screening and frustrates candidates. It must at a minimum cover:

• The main duties and expected results

• The required technical skills (hard skills) and behavioural skills (soft skills)

• The level of experience, salary range and working conditions (remote working, travel, hours)

• Career development prospects at 12–24 months

Including the salary range in the job posting is not just a good practice: in France, certain collective agreements (particularly in construction or metallurgy) impose a classification grid that makes this information mandatory. In Europe, the Directive 2023/970/EU on pay transparency requires employers to communicate about salaries from the start of the recruitment process, with national transposition expected before June 2026.

Choosing the right distribution channels

The matching algorithm of major platforms (Indeed, LinkedIn, Welcome to the Jungle, France Travail) favours structured postings with precise keywords in the title and body. A well-written posting can generate 2 to 4 times more qualified applications than a generic posting, according to benchmarks published by Pôle Emploi.

Phase 2 — Shortlisting, interviews and candidate evaluation

Shortlisting: sorting quickly without discrimination

CV shortlisting is the phase most exposed to unconscious bias. Since Act No. 2008-496 of 27 May 2008 transposing European equal treatment directives, any selection criterion not linked to professional skills is illegal. Automated screening tools (ATS — Applicant Tracking Systems) allow standardisation of evaluation criteria and maintain documentary traceability in case of challenge.

Points to watch:

• Retain reasons for rejection (legal retention period: 2 years, CNIL decision no. 2019-009)

• Inform unsuccessful candidates within a reasonable timeframe (best practice: maximum 15 days)

• Process personal data in compliance with GDPR no. 2016/679, notably the right to erasure

Conducting interviews

An interview process structured in 2 to 3 stages is generally optimal: an initial qualifying interview (often by video), an in-depth interview with the manager, then a possible final interview with management. Beyond 4 stages, candidate drop-out rates increase significantly — a 2023 Glassdoor study shows that a process lasting more than 5 weeks drives away 57% of candidates.

For technical positions, practical tests or assessments can be integrated between stages. These evaluations must be proportionate to the position and respect the confidentiality of results.

Phase 3 — The employment offer and salary negotiation

Drafting a solid employment offer

Once the candidate is selected, the employer generally sends them an employment offer (or offer letter) before signing the final contract. This document, whilst not mandatory under French law, creates legitimate expectations and can, in certain circumstances, be recharacterised as a promise of contract within the meaning of Article 1124 of the Civil Code (Court of Cassation soc. 21 September 2017 ruling). It is therefore essential to draft it carefully.

The offer must mention:

• The position, start date and probation period

• Annual gross salary and variable elements

• Benefits (health insurance, profit-sharing, RTT, company vehicle)

• The candidate's response deadline

To speed up this stage, using an AI-powered contract generator allows you to produce documents compliant with the applicable collective agreement in minutes, without risk of omission.

Salary negotiation: finding the balance

Salary negotiation is often experienced as a tense moment. A few structuring principles:

• Anchor the discussion in market data: rely on sector-specific salary surveys (Apec, Hays, Robert Half) to justify your offer

• Distinguish fixed salary from overall package: sometimes, benefits in kind or employee savings schemes can supplement an offer without impacting payroll

• Set a response deadline: 3 to 5 working days is the norm; beyond that the candidate may feel under pressure or interpret the wait as a negative signal

Phase 4 — Contract signing and onboarding (integration)

Dematerialising contract signing

This is where digital transformation takes on its full meaning. Signing an employment contract by hand involves printing, postal delivery or physical travel, return delays, paper archiving — all friction points that slow down the start date and create risks of document loss.

Qualified or advanced electronic signature allows you to sign a contract in minutes, from any device, with legal value recognised by the Civil Code (Articles 1366–1367) and the eIDAS regulation. To understand the different levels of signature applicable to HR documents, consult our comprehensive guide to electronic signature.

The operational gains are measurable:

• Signing time reduced from 5–7 days to under 24 hours on average

• Elimination of printing and postage costs

• Automatic archiving with timestamping and complete traceability

• Reduced risk of disputes thanks to the audit trail (who signed, when, from which device)

For HR departments managing many hires, it is useful to compare available solutions via our comparison of electronic signature solutions to choose the one that best integrates with existing HRIS (Workday, SAP SuccessFactors, BambooHR, etc.).

Onboarding: from signature to first payslip

Once the contract is signed, the integration process begins. A structured onboarding reduces turnover by 25% and improves new hire productivity by 11% in the first 90 days, according to a 2022 Brandon Hall Group study. The key steps:

• Before day one: send digital welcome pack, create IT access, introduce the team

• Week 1: tool training, meet stakeholders, clarify 30/60/90 day objectives

• First payslip: verify compliance with signed contract (grade, status, health insurance), explain the lines to the new employee

Supplementary documents (health insurance addendum, confidentiality agreement, IT policy) can also be signed electronically via the same platform, ensuring complete documentary consistency from day one. For organisations wishing to standardise their templates, downloadable contract templates are available and cover the main types of employment contracts (permanent, fixed-term, apprenticeship).

Legal framework applicable to the recruitment process and contract signing

The recruitment process is governed by a dense legal framework, at the intersection of labour law, data protection law and electronic evidence law.

Electronic evidence and signature law

Article 1366 of the Civil Code establishes the principle of equivalence between electronic and paper documents, provided that the person's identity is guaranteed and the document's integrity is ensured. Article 1367 specifies the conditions for validity of electronic signature. These provisions are coordinated with eIDAS Regulation no. 910/2014 (and its evolving eIDAS 2.0), which defines three levels of signature: simple, advanced and qualified. For employment contracts, the advanced level (SCA) is generally sufficient, except in special cases (company officers, certain regulated sectors).

Protection of candidates' personal data

GDPR no. 2016/679 applies in full to recruitment. Data collected (CV, cover letters, test results) must be processed on a legal basis (Article 6 GDPR — legitimate interest or performance of pre-contractual measures), retained for a limited period (maximum 2 years for unsuccessful candidates according to CNIL recommendations), and protected by appropriate security measures. The candidate has the right to access, rectify and erase this data at any time.

Non-discrimination and equal treatment

Act No. 2008-496 of 27 May 2008, transposing Directives 2000/43/EC and 2000/78/EC, prohibits any discrimination based on origin, sex, age, disability, religious or political beliefs in the recruitment process. The anonymous CV, whilst no longer mandatory since 2021, remains a best practice in larger organisations. Employers with more than 250 employees are subject to reporting obligations on gender equality (Egapro Index, Decree No. 2019-15).

Pay transparency

Directive 2023/970/EU on pay transparency, to be transposed before June 2026, requires employers to communicate a salary range from the job posting onwards and not to ask candidates about their current salary. It strengthens employees' right to information about pay criteria and introduces sanctions for non-compliance (fines of up to 3% of payroll).

Cybersecurity obligations

Recruitment platforms and electronic signature tools handling sensitive personal data are subject to the requirements of the NIS2 Directive (transposed in France by Act No. 2023-703), which imposes enhanced cybersecurity measures on digital service operators. The standards ETSI EN 319 132 govern the formats of advanced electronic signature (XAdES, PAdES, CAdES) guaranteeing the integrity and non-repudiation of signed contracts.

Use scenarios: digitise recruitment end-to-end

Scenario 1 — An industrial SME with 150 employees and seasonal recruitment

An industrial SME specialising in food processing recruits between 30 and 50 seasonal contracts (fixed-term contracts of 3–6 months) each year between March and July. Before digitalisation, the process involved printing each contract in duplicate, postal delivery to candidates in several regions, then waiting for signed returns — sometimes 10 to 15 days. Signature delays delayed advance notice of hiring declarations (DPAE) and generated requalification risks.

By deploying an electronic signature solution integrated into its ATS, the SME reduced the average signing time to under 4 hours. The 24-hour signature rate exceeds 92%. Automatic archiving of signed contracts (with qualified timestamping) also reduced the time spent on administrative document management by 80%, freeing up two full-time equivalents during peak periods.

Scenario 2 — A management consulting firm with 40 consultants

A consulting firm managing senior profiles (managers, engagement directors) experienced frequent process drop-outs: candidates, often in-post and solicited by multiple employers simultaneously, were reluctant to wait several days for contract delivery and signing. The firm implemented a fully dematerialised workflow: employment offer signed electronically upon verbal agreement, CDI contract automatically generated from a compliant template, signed in less than 2 hours.

Result: the final offer acceptance rate increased by 17 points over 12 months, and the average time between final selection and start date fell from 12 days to 5 days. Costs associated with abandoned recruitments (consulting fees, HR time) decreased by around 25%.

Scenario 3 — A hospital group managing medical and paramedical recruitment

A hospital group with around 900 beds carries out between 400 and 600 recruitments per year, many of which are urgent fixed-term replacements signed at short notice (sometimes the day before for the next day). The challenge is twofold: the legal validity of contracts must be beyond reproach (labour tribunal disputes are frequent in the sector), and speed of execution is critical for continuity of care.

By adopting an eIDAS-compliant electronic signature platform, the group was able to sign replacement contracts in under 30 minutes, even outside business hours, thanks to an adapted mobile interface. The complete audit trail (verified identity, signature time, IP address) made it possible to reduce disputes over contract challenges by 40%, and the legal department estimated a saving of 120 working hours annually in dispute handling.

Conclusion

Optimising the recruitment process — from job posting drafting to delivering the first payslip — relies on a combination of methodological rigour, legal compliance and intelligent digitalisation. Each stage generates risks (discrimination, candidate losses, contract delays) but also efficiency opportunities when properly structured.

Electronic signature is one of the most impactful levers for this transformation: it accelerates hiring finalisation, secures the probative value of contracts and frees HR teams for higher value-added tasks.
