The Limits of Traditional Tech Interviews in DevOps Recruitment

Written by Scalyz Team | Jul 21, 2025 8:00:00 AM

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.

1. What Traditional Methods Assess (and What They Miss)

Traditional technical interviews often rely on questionnaires, multiple-choice tests, or out-of-context coding exercises. While these formats can assess certain knowledge, they don’t reflect the day-to-day reality of a DevOps role. What do they miss? The ability to resolve incidents under pressure, collaborate effectively with a team, automate processes, or integrate tools into an existing infrastructure. These practical, cross-functional, and human skills are at the heart of the job. By overlooking these dimensions, there's a real risk of hiring a good theorist, but a poor operator.

 

2. Why the DevOps Role Requires a Different Kind of Evaluation

DevOps sits at the crossroads of development, operations, automation, and security. It demands a broad understanding of systems, process discipline, and the ability to collaborate with very diverse profiles. Testing a DevOps professional solely on theoretical knowledge means overlooking 70% of what truly adds value to the role. What really needs to be assessed are logic, responsiveness, methodology, adaptability, and communication. These skills emerge in real-world situations, when facing the unexpected or coordinating with other teams. A relevant evaluation must therefore closely simulate the real complexity of the field.

 

3. The Importance of Realistic Simulations

To properly evaluate a DevOps profile, nothing beats a real-world simulation. An immersive technical scenario reveals not only skills but also the reflexes and soft skills that make a difference in production. Here are the key aspects such an exercise can highlight:

  • Thought process: how the candidate analyzes the situation, forms hypotheses, and structures their approach.
  • Prioritization skills: when facing multiple issues, can they identify what’s critical, what can wait, and act accordingly?
  • Documentation: do they take the time to document their choices and leave useful traces for the team?
  • Communication: do they clearly explain their actions, ask the right questions, and raise alerts at the right time?
  • Action under pressure: do they keep their cool and make sound decisions despite stress or uncertainty?

These real-time responses are what truly distinguish a strong candidate from one who only performs well on paper.

 

4. Understanding the Challenge: The Art of Testing in a Complex Technical World

Imagine you're asked to hire a pilot. You could either ask them theoretical questions about flight mechanics, or place them in a simulator and watch how they respond to sudden turbulence or an engine failure.

The parallel is clear: hiring a DevOps without a real-world scenario is like recruiting that pilot without ever seeing them fly. On paper, everything may look perfect, but the moment something goes wrong, the difference becomes obvious.

 

5. Toward a New Approach to DevOps Hiring

To avoid hiring mistakes, companies must rethink their evaluation process. This involves using more immersive formats, building closer connections with technical teams, better understanding the job’s challenges, and valuing soft skills. It’s no longer about filtering candidates based on “keywords,” but about placing them in real-world scenarios of the role they will perform. This approach not only helps identify truly suitable profiles but also reduces post-hire failure rates. Additionally, it strengthens the employer brand by offering candidates a more transparent, engaging, and respectful experience that acknowledges their real skills.

 

6. Rethinking Technical Evaluation: A Method Closer to Reality

Scalyz offers an immersive evaluation platform designed for IT roles, including DevOps. Through interactive labs, candidates face concrete challenges inspired by real-world tasks. Recruiters receive a detailed report on both technical and behavioral skills, enabling more informed decision-making. This approach is fair, fast, and aligned with the realities of the field.

 

Conclusion

Traditional methods are no longer enough to identify the right DevOps profiles. To recruit effectively, you need to go beyond resumes and theoretical questions and focus on more concrete assessments centered on real-world skills. The tools exist; now it's time to adopt them.
