Recruiting talent is one thing. Keeping them is another.
By 2026, onboarding has become a strategic lever for companies, particularly for SMEs. Once reduced to a simple welcome day, it is now a structured process, designed to secure role transition, accelerate skills development, and strengthen engagement.
But the most common mistake is believing that onboarding ends after a few days. In reality, integration plays out over several months — and this is where a second often-forgotten phase comes in: in-depth integration, which prepares the ground for mentoring.
A bit of history: how onboarding became a strategic issue
Before 2010: administrative welcome
Onboarding came down to a badge, a computer, an office tour, and a coffee with the manager. The essentials were administrative.
2010–2020: employee experience

60-day checklist:
90 days: be fully integrated
Objectives: master the role, integrate into projects, understand team challenges, and be autonomous on key missions.

Phase 2: In-depth integration (beyond onboarding)
This is the phase many companies overlook. Yet this is where retention is won.
In-depth integration allows you to reinforce company culture, develop skills, build internal connections, secure the path to autonomy, and avoid the "3-month disillusionment."
It includes:
This is the natural transition to mentoring.
