Question 1

What skills are required to become a DevOps engineer?

Accepted Answer

Technical: a scripting language, Git, Linux, CI/CD, containers, one cloud, infrastructure as code, and monitoring. Soft skills: communication, collaboration, problem-solving, and adaptability—you work with developers and operators, not only with YAML. Build projects, get comfortable with Azure Repos and Azure Pipelines, then apply with that evidence.

Question 2

Does a DevOps engineer know how to code?

Accepted Answer

Yes, enough to automate. Python or PowerShell, Bash, and YAML are the daily languages. You are not replacing product developers; you write the glue that builds, tests, deploys, and observes their software.

Question 3

How are DevOps engineers different from developers?

Accepted Answer

Developers own product features. DevOps engineers own the system that takes those features to production and keeps them there: pipelines, infrastructure, security gates, and observability. The best teams blur the line—developers still run what they ship.

Question 4

How do I prepare for a DevOps interview?

Accepted Answer

Be ready to walk through a real pipeline: Git branching, a YAML pipeline, an IaC module, and how you would debug a failed deploy. Know Linux, networking basics, Docker, and Azure identity (RBAC, managed identity). Have a small repo you can show.

Question 5

What is a DevOps lifecycle?

Accepted Answer

Plan → Code → Build → Test → Release → Deploy → Operate → Monitor, then back to plan. Azure DevOps maps this to Boards, Repos, Pipelines, Artifacts, and Azure Monitor.

Question 6

What is DevOps automation?

Accepted Answer

Anything a human should not repeat: tests, builds, deploys, environment creation, secret injection, and alerts. If it is a wiki of click-ops, it is not automated yet.

Question 7

What is a pipeline in DevOps?

Accepted Answer

A defined path from commit to a running environment. On this roadmap that is Azure Pipelines: YAML in the repo, stages for CI then CD, environments with approvals, and the same artifact promoted to production.

Question 8

What metrics are used in DevOps to measure success?

Accepted Answer

DORA-style: deployment frequency, lead time for changes, change fail rate, and time to restore. Add SLOs the user can feel (availability, latency) and cost per environment so FinOps is not an afterthought.

Question 9

What are some misconceptions about DevOps?

Accepted Answer

That it is only a tool (Jenkins, Azure DevOps, Kubernetes). That one person “is the DevOps.” That more deploys without tests is DevOps. Culture and feedback loops first; tools second.

Question 10

How do Agile and DevOps interrelate?

Accepted Answer

Agile shortens the planning loop; DevOps shortens the delivery loop. Boards (backlog, sprints) without Pipelines leaves work stuck in “done on my machine.” Pipelines without a backlog ships chaos faster.

Question 11

What is the difference between SRE and DevOps?

Accepted Answer

DevOps is the culture and delivery system. SRE is a reliability practice—SLIs, SLOs, error budgets—often sitting on the same Azure stack. You can do DevOps without a formal SRE team; SRE without delivery automation rarely works.

Question 12

What is the difference between DevSecOps and DevOps?

Accepted Answer

DevSecOps is DevOps with security in the same pipeline: secret scanning, SAST, SCA, Azure Policy, and least-privilege identities—not a security review after go-live.

Question 13

What is shift-left in DevOps?

Accepted Answer

Move tests, security, and quality earlier: on the pull request in Azure Repos, not in production. Branch policies and pipeline checks are shift-left in practice.

Question 14

Which tools are most used in DevOps?

Accepted Answer

Git, a CI/CD system, Linux, Docker, a cloud, and IaC. On this 2026 path the defaults are Azure Repos, Azure Pipelines, Azure, Bicep/Terraform, Docker, and Azure Monitor. GitHub Actions, Jenkins, and AWS remain common alternatives.
