What's the difference between a DevOps Engineer and a regular Software Engineer?

A software engineer primarily writes application code. A DevOps engineer focuses on the infrastructure, tools, and processes that allow that code to be built, tested, deployed, and monitored reliably and at scale. They bridge the gap between development ('Dev') and operations ('Ops').

Is experience with a specific cloud provider (like AWS) a deal-breaker?

Often, yes. While the concepts are transferable, the specific services and tools are very different between AWS, GCP, and Azure. If your company is an AWS shop, requiring hands-on AWS experience is a very effective knockout question to ensure a candidate can be productive quickly.

How can I screen for DevOps skills if I'm not technical?

Focus on experience with core concepts and tools. You don't need to know *how* to write a Terraform file, but asking 'Have you used Infrastructure as Code tools like Terraform?' is a perfect way to verify if they have the necessary experience. A real DevOps engineer will know these terms instantly.

DevOps Engineer Screening Questions

Hire engineers who keep your systems running. Use these 20 knockout questions to filter for cloud, container, and CI/CD expertise.

Why Screening DevOps Engineers is Hard

Screening DevOps engineers is tough because the field is incredibly broad. A candidate's resume might be a laundry list of tools (Docker, Kubernetes, Terraform, Jenkins, AWS, GCP), but it's hard to know which ones they've actually used in a production environment. This leads to wasting your senior engineers' time interviewing candidates who only have theoretical knowledge, not practical, hands-on experience.

What to Look For in a DevOps Engineer

A strong DevOps engineer thinks in terms of systems and automation. Look for candidates who have hands-on experience with the three pillars of modern DevOps: a major cloud provider (AWS, GCP, or Azure), containerization (Docker and Kubernetes), and CI/CD pipelines (like GitHub Actions or Jenkins). Experience with Infrastructure as Code (IaC) using tools like Terraform is also a critical signal of a modern, scalable mindset.

20 Knockout Questions for DevOps Engineers

#	Question	Type	Knockout Rule
1	How many years of DevOps or cloud engineering experience do you have?	MCQ: 0-1 / 1-3 / 3-5 / 5+	Below minimum = Knockout
2	Are you hands-on with AWS, GCP, or Azure?	Yes / No	No = Hard Knockout
3	Which cloud platform are you most experienced with?	MCQ: AWS / GCP / Azure / Multi-cloud	Mismatch = Knockout if platform-specific
4	Have you worked with Docker and containerization?	Yes / No	No = Knockout for container-based teams
5	Have you worked with Kubernetes in production?	Yes / No	No = Knockout for K8s-heavy roles
6	Have you built or maintained CI/CD pipelines?	Yes / No	No = Hard Knockout
7	Which CI/CD tool have you used?	MCQ: Jenkins / GitHub Actions / GitLab CI / CircleCI	Mismatch = Red flag
8	Have you used Infrastructure as Code tools? (Terraform, Ansible)	Yes / No	No = Knockout for IaC-focused roles
9	Have you set up monitoring and alerting systems? (Datadog, Grafana)	Yes / No	No = Red flag
10	Have you managed cloud costs or done FinOps work?	Yes / No	No = Red flag for cost-sensitive roles
11	Have you worked with Linux/Unix systems administration?	Yes / No	No = Knockout
12	Have you handled production incidents or on-call rotations?	Yes / No	No = Knockout for SRE roles
13	Do you have any cloud certifications? (AWS, GCP, Azure)	Yes / No	No = Red flag for certification-required roles
14	Have you worked with microservices or distributed systems?	Yes / No	No = Red flag for complex architectures
15	Have you implemented security or compliance policies in cloud?	Yes / No	No = Knockout for security-focused roles
16	Are you authorized to work in [country] without visa sponsorship?	Yes / No	No = Knockout
17	What is your expected salary range?	MCQ: Range bands	Out of budget = Knockout
18	What is your current notice period?	MCQ: Immediate / 2 weeks / 1 month / 2+ months	Mismatch = Knockout
19	Are you open to our work model?	MCQ: Onsite / Hybrid / Remote	Mismatch = Knockout
20	Are you available for an interview within the next 7 days?	Yes / No	No = Deprioritize

How to Use These Questions

Align your questions to your tech stack. If you're an AWS shop that uses Kubernetes and Terraform, make those three questions your non-negotiable knockouts. Use a Sift quiz to automate this first-pass filter. This ensures that every candidate who reaches your technical interview stage already has the foundational experience your team requires, making your hiring process dramatically more efficient.

Common Screening Mistakes

A common error is not being specific enough. Don't just ask "Have you used the cloud?"; ask "Which cloud platform are you most experienced with?". Another mistake is valuing certifications over hands-on experience. While a certification is a good signal, a question like "Have you handled production incidents?" is a much better test of real-world capability.
