In many assignments related to **recrutement ingénieur DevOps** and broader recrutement infrastructure IT, my role as a technical transition manager often involved structuring teams, improving operations, and supporting organizations through critical change. Very quickly, one observation became clear: the main challenge is not only identifying profiles, but truly ensuring **validation compétences ingénieur**. Traditional interviews and CV-based screening are no longer sufficient for a reliable évaluation compétences IT. This is what led me to explore more practical and realistic approaches, centered around **test technique DevOps**, and the use of a **plateforme évaluation technique** designed to assess real-world capabilities rather than theoretical knowledge alone.   **Table of Contents** [1.

Hiring and restructuring are constant activities When restructuring a team, hiring becomes a recurring activity. Sometimes you need to strengthen the team. Sometimes you need to realign certain skills. And over the years, I’ve led many recruitment processes. This allowed me to clearly see what works and what leads to mistakes. I also realized how much the quality of hiring directly impacts team performance. And above all, how a poor decision can cost time, energy, and trust. Over time, hiring becomes less of a one-time task and more of a strategic lever. ## 2. The interview gap Many candidates looked excellent during interviews. They had strong CVs. They spoke confidently about technologies. But once in real environments, some struggled to adapt. The gap between interview performance and operational capability became visible. This gap created challenging situations for the existing teams. It often required additional support, correcting certain decisions, or sometimes re-evaluating the initial choice. Over time, this pattern appeared repeatedly: interviews validated candidates on paper, but not always in action. And that’s precisely where the risk became most apparent. ![Iceberg - Real talent is invisible - Scalyz](https://blog.scalyz.com/hs-fs/hubfs/Iceberg%20-%20Real%20talent%20is%20invisible%20-%20Scalyz.png?width=500&height=419&name=Iceberg%20-%20Real%20talent%20is%20invisible%20-%20Scalyz.png)     ## 3. The idea of simulation To reduce that gap, I started experimenting with something simple. Instead of relying only on conversations, I created **technical simulations**. Small scenarios reflecting the environments we were operating. I wanted to observe: - how engineers approached problems - how they navigated unfamiliar systems - how they reasoned when things were not straightforward. The insights were incredibly valuable.   ## 4. L’optimisation continue grâce aux données Over time, the idea evolved. What if this process could be automated? What if companies could evaluate engineers through realistic environments without building custom setups every time? This question eventually led to the creation of [**Scalyz**](http://scalyz.com). Not as a theoretical assessment tool, but as a practical extension of how technical teams are actually built. The philosophy behind Scalyz is simple. Technical capability is best understood when engineers interact with real environments. Not only when they describe them.   ## Conclusion : Over time, a conviction became clear: evaluating an engineer solely through interviews is not enough to understand their true ability to perform. What makes the difference are real-world situations, decisions made under constraints, and the way they act when facing the unknown. It was this on-the-ground reality that inspired the creation of Scalyz: to provide a fairer, more concrete evaluation, closer to the daily work of technical teams. After all, effective recruitment isn’t just about validating a candidate. It’s about reducing uncertainty and building strong teams from the start.
