A free AI panel interview for the DevOps / SRE role: it follows up when an answer is thin and returns a scored, evidence-backed report. Optionally run it in a specific company’s interview style, and 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
Key topics
Typical DevOps / SRE interview rounds
-
1. Linux & systems
-
2. CI/CD & IaC
-
3. Containers & orchestration
-
4. Reliability & incident
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.
DevOps / SRE interview FAQ
- 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.
