The hiring of artificial intelligence profiles is accelerating. Data scientists, machine learning engineers, AI engineers… these roles have become strategic for many companies. Yet, a large part of recruitment processes still relies on traditional technical interviews: theoretical questions, discussions about past projects, and standard algorithmic tests.

In a highly competitive IT market, every company wants to hire the best talent. But one question keeps coming up: how can you quickly identify truly high-performing engineers? Not all strong CVs are equal. And not all candidates who perform well in interviews are the most effective on the job. Identifying the top 10% isn’t about slowing down. On the contrary, it relies on a better understanding of key signals from the very first stages of the process. Table of Contents 1. What Truly Sets the Top 10% Apart 2.

Recruitment in technical consulting often feels like a race. A client opens a position, several consulting firms compete, and everyone tries to send profiles as quickly as possible. Speed matters, but there is a paradox in technical recruitment: speed without proof often creates more work later. Table of Contents 1. The illusion of fast recruitment 2.

A candidate may perfectly recite concepts… yet be unable to solve a real problem. In IT hiring, this situation is more common than we think. Today, many recruitment processes still prioritize theoretical knowledge: degrees, certifications, and answers to technical questions. However, what truly makes the difference in real-world situations is practical skills. In this article, you will understand the difference between knowledge and real skills, why this confusion is problematic, and how to better evaluate IT candidates. Table of Contents 1.

In consulting, relationships with clients are built over time. They are built through reliability, consistent delivery, and trust in the people you send to their teams. But trust is fragile. And sometimes, it can be damaged by something that seems small at first: sending the wrong consultant to a client. Table of Conetnt 1. The moment a consultant joins a team 2. The visible cost 3.

How long does it take you to hire a developer, a cloud engineer, or a DevOps expert? In many companies, the IT time-to-hire easily stretches over several weeks, or even months. During that time, projects fall behind, teams come under pressure, and top candidates accept offers elsewhere. The issue isn’t just a shortage of talent. In many cases, it’s overly long, poorly structured, or inefficient hiring processes that slow down decision-making. Reducing time-to-hire in IT has therefore become a strategic priority for companies, consulting firms, and recruitment agencies. The goal is not just to move faster, but to hire smarter while maintaining a high level of technical standards. In this article, you’ll discover the main causes of lengthy IT hiring processes, strategies to speed them up, and tools that help you make faster decisions while ensuring high-quality hires.

In the infrastructure and DevOps world, I have interviewed hundreds of engineers over the years. Many of them looked excellent on paper : Strong CVs, recognized companies, impressive certifications, and clear answers during interviews. Yet sometimes, a few days after joining the team, the reality becomes visible. The first real incident happens. A deployment pipeline fails. A Linux service stops responding. A production issue needs investigation. And suddenly the confidence seen during the interview disappears. This situation is not rare. In fact, it happens much more often than most companies are willing to admit. And the reason is simple: traditional interviews measure knowledge, not operational capability.

Recruiters often rely on traditional methods, generic job descriptions, knowledge-based tests, or simple interviews, to hire DevOps profiles. Yet in an environment where infrastructures evolve rapidly, these approaches quickly show their limits. They struggle to reveal practical skills, the ability to solve complex problems in context, or adaptability to modern tools. This article explores why these methods fail to identify the right candidates and proposes a new way to assess the skills that truly matter in real-world situations. Table of Contents 1.
