Optimal recruitment process: From search to hiring

Hiring the right candidate at the right time is one of the most costly challenges for companies. According to a study by the Society for Human Resource Management (SHRM, 2024), the average cost of recruitment ranges 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 provides you with a comprehensive and expert guide to structure each step 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 publishing any job offer, 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 specify:

• Main tasks and deliverables expected in the first 90 days

• Technical skills (hard skills) required and differentiating

• Behavioural skills (soft skills) consistent with company culture

• Hierarchical positioning and cross-team interactions

• Salary range, made mandatory in several EU countries following Directive 2023/970 on salary transparency

Evaluate the "build vs buy"

Will you recruit externally or upskill an existing employee? This strategic decision should be made before officially opening the position. Internal mobility reduces 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 vary depending on the profiles you're looking for:

• Generalist job boards (Indeed, APEC, Pôle Emploi) suit 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 quality-to-cost ratio: referrals have a retention rate 45% higher than average (source: Deloitte Human Capital, 2024)

Optimise the job offer for SEO and attractiveness

A poorly written offer 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

• Highlight the purpose and impact of the role

• Avoid internal jargon and opaque acronyms

3. Pre-selection and qualification of applications

A structured pre-selection process drastically reduces time spent on unnecessary interviews.

Implement an ATS (Applicant Tracking System)

A candidate management software (ATS) centralises CVs, automates acknowledgements of receipt, and facilitates collaboration between recruiters and managers. In France, approximately 60% of companies with more than 250 employees use an ATS (Markess by exægis, 2025). For SMEs, solutions like Recruitee, Teamtailor or Ashby provide accessible entry points.

Build an objective assessment grid

The scoring grid allows you to compare candidates against 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 and following on non-discrimination in recruitment). Each criterion must be weighted according to its actual importance for the role.

Conduct a telephone pre-qualification interview

A 15 to 20-minute call allows you to verify non-negotiable prerequisites (availability, salary expectations, geographical mobility) before investing time in a physical or video interview. This filter can reduce the number of candidates to interview 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 based on past behaviour. It forces candidates to give concrete and measurable examples, whereas conventional open-ended questions encourage generic responses.

Integrate practical exercises and simulations

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

• Case studies (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 timeline. A 2 to 3-step process is sufficient in the vast majority of cases.

5. Decision, offer and contract formalisation

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

Make a competitive and quick offer

According to a Robert Half survey (2025), 50% of candidates receive multiple offers simultaneously. The average acceptable timeframe between the final interview and the 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, health insurance, profit-sharing, company car, etc.)

• Expected start date

• Expected response deadline

Dematerialise the employment contract signature

Once the offer is accepted, contract formalisation is often the final bottleneck. Handwritten signatures impose postal delays, risks of loss or oversight, and a degraded candidate experience at a critical moment. Electronic signature for HR allows you to sign employment contracts, employment offers or amendments in 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 levels of signature applicable to HR documents, the complete guide to electronic signature details the selection criteria between simple, advanced and qualified signatures. For contracts with significant stakes (senior executives, 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 signature

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). As soon as electronic signature is obtained, the integration file (IT charter, staff regulations, DPAE form) can be transmitted automatically thanks to document workflows integrated into modern solutions. The AI-powered contract generator by Certyneo allows you to produce and send all hiring documents for signature in just a few clicks, without 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, trade union membership, or family situation. The recruiter must ensure that the evaluation criteria used — scoring grids, interview questions, psychometric tests — are strictly linked to the objective requirements of the role.

In terms of 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: processing must be based on the employer's legitimate interest (art. 6.1.f) or explicit candidate consent

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

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

• ATSs must be subject to an impact assessment (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 writing, provided that the signature allows the identification of its author and guarantees 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 (NDAs)

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

Service providers of trust services (Trust Service Providers) issuing qualified certificates must appear 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 EU Directive 2023/970/EU, employers in the EU are required to communicate, before or during the first interview, an indicative salary range. This obligation, gradually transposed in member states by 2026, directly impacts the drafting of job offers and salary negotiation practices.

Use cases: dematerialised recruitment in practice

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

An SME in the industrial sector, managing on average 30 recruitments per year, encountered a recurring problem: after selecting the successful candidate, contract formalisation took on average 10 to 12 working days (printing, postal sending, waiting for return, digitalisation). This delay regularly caused last-minute withdrawals, as candidates accepted competing offers that were more responsive.

By integrating an advanced electronic signature solution into its HR process, the company reduced this timeframe 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 director from their respective interfaces. The reduction in post-offer withdrawal rate is estimated at 35% over the 12 months following implementation.

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

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

Thanks to a fully dematerialised workflow — offer formalised as a secure PDF, electronic signature from smartphone, automatic probative value archiving — the firm eliminated all 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 medical personnel recruitment

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 amendment agreements, patient data confidentiality agreements.

The grouping deployed an advanced electronic signature solution compliant with eIDAS, with reinforced signer authentication (SMS OTP + identity verification). Each signed contract is automatically archived in a certified electronic safe with NF Z 42-020 certification, guaranteeing its probative value for 10 years. The HR department reduced by 60% the time spent on administrative contract follow-up, allowing these resources to be reallocated 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 conditions the quality of the next. From precise need definition to targeted sourcing, from structured evaluation to swift decision, each phase must be equipped, documented and measured. The dematerialisation of employment contract signature represents the final step often overlooked, yet decisive for candidate experience and HR responsiveness.
