DevOps has become the backbone of modern software development. But there’s a subtle yet crucial question that companies often miss during interviews: Were you involved in building DevOps pipelines and infrastructure from scratch, or only partially?
Understanding this difference can make or break your chances of being considered a true full-stack DevOps engineer.
From Scratch vs Partial Involvement
When hiring a DevOps engineer, companies need to evaluate how much of the DevOps lifecycle you’ve actually handled.
1.From Scratch
If you’ve been involved from the beginning, you likely:
Designed CI/CD pipelines end-to-end.
Configured servers, cloud services, and networking.
Automated builds, deployments, monitoring, and logging.
Implemented security policies, secrets management, and compliance.
Managed scaling, high availability, and fault tolerance.
Value: Engineers who have done this can own end-to-end DevOps responsibilities and solve problems across the entire software lifecycle.
2.Partial / Half Involvement
Many engineers are only partially involved in DevOps tasks:
Writing Jenkins pipelines without managing infrastructure.
Deploying Docker images but not designing pipelines.
Configuring monitoring dashboards without integrating alerts.
Problem: These engineers may know some tools, but they often lack the holistic understanding required for full-stack DevOps, where integration, automation, and architecture thinking are critical.
Why Companies Expect Full-Stack DevOps
Even if a candidate has only been partially involved, companies expect them to:
Bridge gaps between development and infrastructure.
Take a half-built pipeline and optimize or complete it.
Understand the full DevOps flow, even if they haven’t personally implemented every part.
Reality Check: Many companies assume that DevOps engineers can handle everything from scratch. Engineers with only partial experience may struggle when asked to implement full-stack solutions.
Key Questions Companies Should Ask
To properly evaluate a candidate’s experience, interviews should include:
1.Pipeline Ownership: “Have you implemented CI/CD pipelines from scratch, or only modified existing ones?”
2.Infrastructure Design: “Can you design infrastructure for a microservices application and automate deployment?”
3.Problem Solving: “How did you handle failures or scaling issues in your previous pipelines?”
4.Knowledge Gaps: “Which parts of DevOps did you not touch, and how would you approach them now?”
These questions separate engineers who are tool users from those who truly own the full DevOps lifecycle.
Conclusion
Companies must ask if a candidate was involved from scratch or halfway. Full-stack DevOps expectations are high because engineers are expected to understand and integrate the full DevOps lifecycle, even if they’ve only worked on parts of it before.
For engineers, it’s crucial to highlight not just the tools you’ve used, but the entire scope of your involvement—from designing infrastructure to deploying applications and handling production issues.
Being able to demonstrate end-to-end ownership is what separates a DevOps engineer from a DevOps tool user.
