Optimal recruitment process: From search to hiring

Hiring the right candidate at the right time is one of the most costly challenges for businesses. According to a study by the Society for Human Resource Management (SHRM, 2024), the average cost of a recruitment is between €3,000 and €5,000 for a non-management position, and can exceed €15,000 for a senior profile. Yet many organisations still approach recruitment reactively, without a formalised process. This article offers you a comprehensive and expert guide to structuring each stage of your recruitment process — from sourcing to signing the employment contract — by integrating best HR practices and digital tools that accelerate the entire chain.

1. Define recruitment needs precisely

Before any job posting is published, the scoping phase is decisive. A poorly defined need leads to unsuitable applications, unnecessary interviews and, ultimately, premature turnover.

Write a complete job description

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

• Main responsibilities and deliverables expected in the first 90 days

• Technical skills (hard skills) required and differentiating

• Behavioural skills (soft skills) in line with company culture

• Hierarchical positioning and inter-team interactions

• Salary range, made mandatory in several EU countries following the 2023/970 directive on pay transparency

Evaluate the "build vs buy"

Will you recruit externally or upskill an internal employee? This strategic decision must be made before the position is officially opened. Internal mobility reduces the average recruitment time by 40% and improves retention according to LinkedIn Talent Solutions (2025).

2. Sourcing and distribution: attracting the right profiles

Once the need is defined, the objective is to build a pool of qualified candidates as quickly as possible.

Choose the right distribution channels

Channels are not equal depending on the profiles being sought:

• General job boards (Indeed, APEC, Pôle Emploi) are suitable for volumes and standard profiles

• LinkedIn Recruiter is essential for management profiles and direct approaches (active sourcing)

• Specialist networks (Malt for freelancers, Welcome to the Jungle for startups, Doctolib Jobs for healthcare) target specific communities

• Employee referrals remain the channel offering the best value for money: referred employees show a retention rate 45% higher than average (source: Deloitte Human Capital, 2024)

Optimise the job posting for SEO and attractiveness

A poorly written posting loses up to 70% of qualified applications according to Textio (2024). A few essential rules:

• Exact job title, searchable on Google for Jobs

• Ideal length: 300 to 500 words

• Highlighting the purpose and impact of the role

• Avoid internal jargon and opaque acronyms

3. Screening and qualification of applications

A structured screening process drastically reduces the time spent on unnecessary interviews.

Implement an ATS (Applicant Tracking System)

Applicant tracking software (ATS) centralises CVs, automates receipts, and facilitates collaboration between recruiters and managers. In France, approximately 60% of companies with over 250 employees use an ATS (Markess by exægis, 2025). For SMEs, solutions such as Recruitee, Teamtailor or Ashby offer accessible entry points.

Build an objective evaluation grid

The scoring grid allows candidates to be compared on identical and documented criteria. It prevents cognitive biases (affinity, halo effect) and meets the objectivity requirements imposed by the Labour Code (articles L. 1132-1 et seq. on non-discrimination in hiring). Each criterion must be weighted according to its actual importance for the position.

Conduct a telephone pre-qualification interview

A 15 to 20-minute call verifies non-negotiable prerequisites (availability, salary expectations, geographical mobility) before investing time in a face-to-face or video interview. This filter can reduce the number of candidates to be invited by 30% without loss of quality.

4. In-depth evaluation: interviews and tests

Multi-criteria evaluation is the phase that determines the quality of the recruitment decision.

Structure interviews using the STAR method

The STAR method (Situation, Task, Action, Result) is the most empirically validated for predicting future performance from past behaviour. It forces the candidate to give concrete and measurable examples, whereas typical open questions favour generic answers.

Integrate practical exercises and role-playing scenarios

According to a meta-analysis published in the Journal of Applied Psychology (Schmidt et al., 2016, regularly replicated data), the combination of structured interview + skills test presents the best predictive value of performance (r = 0.63). Assessments can take the form of:

• Practical cases (business case, coding exercise, marketing campaign review)

• Certified personality tests (MBTI, DISC assessments, or standardised WAIS tools for certain positions)

• Assessment centres for management positions

Involve stakeholders without creating a committee

Collaborative recruitment improves team buy-in for the future colleague. However, multiplying interlocutors beyond 3 rounds unnecessarily lengthens the decision-making time. A 2 to 3-stage process is sufficient in the vast majority of cases.

5. Decision, offer and contract formalisation

The final phase is where many recruitments fail: the successful candidate accepts another offer, or administrative delays discourage.

Make a competitive and quick offer

According to a Robert Half survey (2025), 50% of candidates receive multiple offers simultaneously. The average acceptable time between the final interview and written proposal is 5 working days. Beyond that, the acceptance rate drops significantly. The offer must include:

• Fixed and variable remuneration detailed

• Benefits (remote working, mutual insurance, profit-sharing, company vehicle, etc.)

• Intended start date

• Expected response time

Dematerialise the employment contract signature

Once the offer is accepted, contract formalisation is often the final bottleneck. Handwritten signature requires postal delivery times, risks of loss or oversight, and a degraded candidate experience at a critical moment. Electronic signature for HR makes it possible to have employment contracts, job offer letters or amendments signed in a matter of minutes, from any device. This approach is fully legal in France and the EU, regulated by the eIDAS regulation and article 1366 of the Civil Code.

To understand the different signature levels applicable to HR documents, the comprehensive electronic signature guide details the criteria for choosing between simple, advanced and qualified signatures. For high-stakes contracts (senior managers, non-compete clauses, confidentiality agreements), advanced electronic signature is recommended; the comparison of electronic signature solutions will help you select the platform suited to your volume and sector.

Prepare onboarding from the signature onwards

The recruitment process does not end with contract signature: it continues in the first weeks of integration. A structured onboarding programme reduces the departure rate before the end of the probationary period by 50% (Harvard Business Review, 2024). From the moment electronic signature is obtained, the integration file (IT charter, internal regulations, DPAE form) can be transmitted automatically thanks to document workflows integrated into modern solutions. The AI-powered contract generator from Certyneo allows you to produce and send for signature all hiring documents in a few clicks, with no manual re-entry.

Legal framework applicable to the recruitment process and employment contract signature

Non-discrimination and candidate data protection

French and European law strictly regulate recruitment practices. Article L. 1132-1 of the Labour Code prohibits any discrimination based on origin, gender, age, state of health, religion, political opinions, union membership, or family situation. The recruiter must ensure that the evaluation criteria used — scoring grids, questions asked in interviews, psychometric tests — are strictly linked to the objective requirements of the position.

With regard to personal data, the collection and processing of CVs, cover letters and test results are subject to the General Data Protection Regulation (GDPR, No. 2016/679). The main obligations are:

• Legal basis: the processing must be based on the employer's legitimate interest (art. 6.1.f) or the candidate's explicit consent

• Retention period: data from a non-selected candidate cannot be retained without express consent beyond 2 years from last contact (CNIL recommendation, decision No. 2019-001)

• Right of access and erasure: any candidate can request access to or deletion of their data

• ATSs must be subject to an impact analysis (DPIA) if the processing presents a high risk (automated scoring algorithm, for example)

Legal validity of electronic employment contract

Electronic signature of the employment contract is expressly recognised by the Civil Code in articles 1366 and 1367, which establish the principle of equivalence between electronic and paper written form, provided that the signature makes it possible to identify its author and guarantee the integrity of the document. The eIDAS Regulation No. 910/2014 distinguishes three levels:

• Simple electronic signature (SES): sufficient for the majority of standard CDI/CDD employment contracts

• Advanced electronic signature (AES): recommended for management contracts, non-compete clauses, confidentiality agreements (NDA)

• Qualified electronic signature (QES): legal equivalent of handwritten signature, required for certain notarial deeds or high-stakes financial commitments

Trust Service Providers issuing qualified certificates must be listed on the national trust list published by ANSSI in France. The standards ETSI EN 319 132 (XAdES) and ETSI EN 319 122 (CAdES) govern advanced electronic signature formats guaranteeing long-term probative archiving.

Salary transparency directive (2023/970/EU)

Since the adoption of the European Directive 2023/970/EU, employers in the EU are required to communicate a salary range before or at the first interview. This obligation, gradually transposed into the Member States by 2026, directly impacts the writing of job advertisements and salary negotiation practices.

Use cases: dematerialised recruitment in practice

Scenario 1 — An industrial SME of 120 employees reduces its contract time from 12 to 2 days

An industrial SME managing an average of 30 recruitments per year encountered a recurring problem: after selecting the successful candidate, formalising the employment contract took an average of 10 to 12 working days (printing, postal delivery, waiting for return, digitisation). This delay regularly caused last-minute withdrawals, with candidates accepting a more responsive competing offer in the meantime.

By integrating an advanced electronic signature solution into its HR process, the company reduced this time to less than 48 hours. The contract template is automatically generated from data entered in the ATS, sent for signature to the candidate and countersigned by the HR manager from their respective interfaces. The reduction in the post-offer withdrawal rate is estimated at 35% over the 12 months following implementation.

Scenario 2 — A strategy consulting firm manages its senior profile recruitment remotely

A consulting firm employing about fifty consultants recruits mainly senior profiles from leading schools or with international experience. These candidates are often working abroad or in permanent mobility. Postal delivery of contracts was incompatible with their constraints.

Thanks to a fully dematerialised workflow — formalised offer in secure PDF, electronic signature from smartphone, automatic archiving with probative value — the firm eliminated any friction in the final recruitment phase. Contracts are signed on average 6 hours after sending, compared to 8 days previously. The quality of candidate experience is regularly cited in interview feedback as a positive differentiating factor.

Scenario 3 — A network of private clinics secures the recruitment of medical personnel

A grouping of private clinics comprising approximately 600 beds and several dozen establishments regularly recruits doctors, nurses and paramedical staff. These recruitments involve sensitive documents: fixed-term replacement contracts, on-call amendments, confidentiality agreements on patient data.

The group has rolled out an advanced electronic signature solution compliant with eIDAS, with strengthened signer authentication (SMS OTP + identity verification). Each signed contract is automatically archived in a certified digital safe (NF Z 42-020), guaranteeing its probative value for 10 years. The HR department has reduced by 60% the time spent on administrative follow-up of contracts, allowing resources to be redeployed to support and retention missions.

Conclusion

An optimal recruitment process is not simply a series of linear steps: it is an integrated system where each link determines the quality of the next. From precise need definition to targeted sourcing, from structured evaluation to rapid decision-making, each phase must be tooled, documented and measured. The dematerialisation of employment contract signature represents the final often-overlooked step, yet decisive for candidate experience and HR responsiveness.
