Optimal recruitment process: from search to hiring

Introduction

In an increasingly competitive labour market, mastering each stage of the recruitment process has become a strategic imperative for organisations of all sizes. According to a 2025 DARES study, the average cost of a failed recruitment represents between 30,000 and 50,000 € for an SME, without counting the impacts on productivity and team cohesion. From defining the need to signing the employment contract, each phase must be carefully thought through, structured and equipped with the right tools. This article provides you with a comprehensive guide to building an effective, legally compliant and fully digitalised recruitment process.

Phase 1: Define the need precisely and prepare the ground

Before publishing a single job advert, the preparation phase is decisive. A vague or incomplete job description is the primary cause of a high volume of unqualified applications, unnecessarily extending delays.

Build the job description and ideal candidate profile

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

• Core responsibilities with an order of priority

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

• The level of experience expected and any prerequisite qualifications

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

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

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 tailored to the profile being sought:

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

• LinkedIn Recruiter for executive and specialist profiles

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

• Internal recommendation: 45% of CAC 40 companies state that co-optation 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 means paying as much attention to the attractiveness of the offer as to the rigour of the selection process.

Write an optimised job advert

A well-written advert is a employer brand lever in its own right. Best practices include:

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

• An engaging introduction that highlights company culture and differentiating advantages

• A clear structure: bullets, short paragraphs, information hierarchy

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

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

Implement a structured pre-selection process

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

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

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

• Skills tests: case studies, technical tests, practical scenarios

• Structured in-person interview with the manager and an 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 French Labour Code. To limit them:

• Use a standardised evaluation grid shared among all recruiters

• Train managers in behavioural interviewing

• Involve multiple evaluators with different perspectives (panel interview)

• Document criteria for rejection and selection at each stage

Make the decision and formulate the offer

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

• The exact job title and statutory classification

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

• The start date and duration of the probation period

• The timeframe expected for the candidate's response

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

Phase 4: Finalise the hiring and digitalise contracting

From employment promise to employment contract

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

A permanent employment contract (CDI) is not subject to any mandatory legal formality except in specific cases (part-time work, fixed-term contract, apprenticeship), but the applicable collective agreement may require a written agreement. It is in all cases strongly advisable to formalise it in writing.

Digitalise employment contract signature

Electronic signature of the employment contract represents a considerable saving in time and reliability. It makes it possible 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 mobile before their first day

For HR contracts, electronic signature for HR compliant with the eIDAS regulation is legally equivalent to handwritten signature provided that an advanced signature level (SES or QES) is used.

The use of an AI-powered contract generator 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 end with contract signature. Onboarding is a critical phase: according to the Society for Human Resource Management (SHRM), structured onboarding improves retention at 3 years by 82%. Best practices include:

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

• Designating an internal mentor or buddy

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

• Digitalised signature of onboarding documents (employee 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 team member's performance at 6 months and 1 year

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

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

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

Integrate continuous improvement approach

Regular analysis of these KPIs helps identify bottlenecks: overly long pre-selection phase, high dropout rate between offer and signature, gap between recruited profile and manager 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 via candidate experience surveys.

Legal framework applicable to recruitment contracting

French Labour Code and contract law

Formalising recruitment is governed by several legal provisions that are essential to understand.

Article L1221-1 of the French Labour Code provides that the employment contract is subject to common law rules. 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 French Civil Code (from ordinance n°2016-131 of 10 February 2016 reforming contract law) establish the legal framework for electronic signature in France: electronic writing has the same probative force as paper writing provided that the identity of the author can be duly identified and the document is kept 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 low-risk legal documents

• 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 notarised deeds

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

GDPR and candidate data protection

Processing 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

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

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

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

In the event of a personal data breach of candidates (CV leak, unauthorised ATS access), 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 French Labour Code prohibits any discrimination in recruitment based on origin, gender, 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 about fifty recruitments per year faced average delays of 65 days between posting offers and signing contracts. The main bottleneck? Postal delivery of contracts and back-and-forth corrections and signatures.

By deploying 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 contract and amendment mailings

• Centralise proof of signature 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 in recruitment costs (interim cover, productivity loss from vacant position).

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

An HR consulting firm assisting 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 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 clients a dedicated portal to track signature status in real time

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

• Charge clients for a high-value digitalised contracting service, increasing average client spend by 18%

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

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

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

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

• Reduce average contracting time 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 checks

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

Conclusion

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