1 What is DevOps and why is it important?

DevOps is a set of practices and tools that aim to improve the collaboration and efficiency of software development and IT operations teams. DevOps enables faster delivery of software features, higher quality of products, and lower costs of maintenance and deployment. DevOps also fosters a culture of continuous learning and improvement, where teams can experiment, test, and learn from feedback and data.

DevOps is important because it closes the gap between the operations and development teams. Due to the fast-paced nature of our current tech industries, DevOps is necessary to keep up with the demands by using microservices and decoupling various aspects of tech infrastructures for smooth production, deployments, and rollbacks if needed.

2 What are some common DevOps tools and how do you use them?

There are many tools that support DevOps practices, such as version control, configuration management, automation, testing, monitoring, and logging. Some examples of popular DevOps tools are Git, Jenkins, Ansible, Docker, Kubernetes, Selenium, Nagios, and ELK stack. You should ask the DevOps engineer how they use these tools to manage the software development lifecycle, from coding and testing to deployment and operation. You should also ask them how they integrate these tools with each other, and what challenges they have faced or solved with them.

3 How do you implement continuous integration and continuous delivery (CI/CD)?

Continuous integration and continuous delivery are core DevOps practices that enable frequent and reliable delivery of software products. Continuous integration means that developers merge their code changes to a shared repository regularly, and run automated tests to ensure quality and compatibility. Continuous delivery means that the code is ready to be deployed to any environment at any time, using automated pipelines that can deploy to different stages, such as development, testing, staging, and production. You should ask the DevOps engineer how they set up and maintain CI/CD pipelines, what tools they use, and how they ensure security and compliance.

4 How do you monitor and troubleshoot software performance and reliability issues?

Monitoring and troubleshooting are essential skills for a DevOps engineer, as they need to ensure that the software products are running smoothly and meeting the user expectations and business goals. Monitoring means collecting and analyzing data on various metrics, such as availability, latency, throughput, errors, and user feedback. Troubleshooting means identifying and resolving the root causes of issues, using tools such as logs, alerts, dashboards, and tracing. You should ask the DevOps engineer how they monitor and troubleshoot software performance and reliability issues, what tools they use, and how they communicate and collaborate with other teams.

5 How do you automate tasks and processes in DevOps?

Automation is another key DevOps practice that helps reduce human errors, save time and resources, and increase consistency and scalability. Automation can be applied to various tasks and processes in DevOps, such as testing, deployment, configuration, provisioning, backup, recovery, and security. You should ask the DevOps engineer how they automate tasks and processes in DevOps, what tools they use, and how they test and update their automation scripts.

6 How do you handle security and compliance in DevOps?

Security and compliance are crucial aspects of DevOps, as they ensure that the software products are safe and adhere to the relevant standards and regulations. Security and compliance should be integrated into the DevOps workflow, rather than treated as a separate or final stage. This is also known as DevSecOps, which emphasizes the shared responsibility and collaboration of all teams involved in software delivery. You should ask the DevOps engineer how they handle security and compliance in DevOps, what tools and practices they use, and how they deal with vulnerabilities and incidents.
