What does a DevOps / SRE interview cover?

Linux and networking fundamentals, CI/CD and release automation, containers and Kubernetes, infrastructure-as-code (Terraform/Ansible), observability (metrics/logs/tracing, SLIs/SLOs), and incident response — usually with hands-on debugging scenarios.

Is DevOps/SRE a coding interview?

Partly — expect scripting (Bash/Python) and automation over heavy DSA, plus strong systems reasoning, pipeline/infra design, and reliability engineering. SRE roles lean more on systems and on-call judgement.

Can I practise a DevOps / SRE interview for a specific company?

Yes. Start the DevOps / SRE mock and choose a company to run it in that company's interview style — the scorecard stays the DevOps / SRE role's. You can also add your CV so the panel asks about your real projects.

What a DevOps / SRE interview covers

A DevOps / SRE interview focuses on CI/CD, containers, infrastructure-as-code, observability and reliability. The core competencies assessed are:

Linux, networking and scripting (Bash/Python) fundamentals
CI/CD pipelines and release automation
Containers and orchestration — Docker and Kubernetes
Infrastructure-as-code — Terraform, Ansible
Observability — metrics, logs, tracing, SLIs/SLOs
Incident response, on-call and blameless post-mortems

Typical DevOps / SRE interview rounds

Linux & systems

Processes, permissions, networking, and a "why is this box slow / this service failing" debugging scenario.
CI/CD & IaC

Design a pipeline; reason about Terraform/Ansible, immutable infra, and safe rollouts/rollbacks.
Containers & orchestration

Docker internals and Kubernetes — scheduling, services, scaling, and failure handling.
Reliability & incident

SLIs/SLOs and error budgets, plus walking through an incident you handled and its post-mortem.

How to prepare

Do

Be strong on Linux and networking fundamentals — they underpin every scenario.
Know Kubernetes beyond commands: scheduling, health checks, and what fails under load.
Frame reliability in SLI/SLO/error-budget terms, not just "uptime".
Have a real incident story with the post-mortem and what you changed.

Avoid

Knowing tool commands but not the systems fundamentals beneath them.
Designing a pipeline with no rollback or testing strategy.
Ignoring observability — you cannot operate what you cannot see.
No concrete on-call/incident example for the behavioural round.

Practise in a company’s style

Start the DevOps / SRE mock and pick any company to run the interview in that company’s style — the questions and scorecard stay the DevOps / SRE role’s, while the panel’s tone and behavioural questions reflect the company. Add your CV and it will ask about your real projects and experience.
