junior devops engineer interview questions

DevOps is one of the hottest buzzwords in tech now, although it is much more than buzz. The development team and the operations team work together to get a product out the door faster and more efficiently. In the past few years, there has been a tremendous increase in job listings for DevOps engineers. Multinational companies, like Google, Facebook, and Amazon, frequently have multiple open positions for DevOps engineer Experts. But it’s hard to get a job, and the questions you might be asked in a DevOps engineer interview could be about a lot of tough topics. Â.

After taking the DevOps Course and starting to get ready for roles in IT development and operations, you know that it’s a tough field that will require a lot of hard work to get into. We’ve put together a list of some of the most common DevOps interview questions and answers to help you get ready for jobs in the field.

DevOps is a set of activities and approaches that bring together software development (Dev) and IT operations (Ops) to make software development, delivery, and deployment faster and better.

The main goal of DevOps is to get the development and operations teams to work together more, so they can easily work together throughout the whole software development life cycle. Automation, continuous integration, delivery, and deployment are also used to make the software development process faster and less likely to make mistakes.

DevOps also stresses monitoring and feedback, which helps the development and operations teams spot problems early and take care of them before they get worse. By getting faster release cycles, better software, and better teamwork, DevOps methods can help businesses become more flexible, competitive, and productive overall.

Technical Questions on Fundamentals

Hiring managers will want to know how well you understand basic DevOps concepts and tools. Be ready to explain:

  • What is DevOps?

Show that you understand that DevOps is the combination of software development (dev) and IT operations (ops) to get apps to users faster by developing and deploying them all the time.

  • What are some benefits of DevOps?

Highlight faster delivery, increased collaboration, improved quality, and better managing of complex infrastructures.

  • How is DevOps different from the traditional software development lifecycle?

The traditional SDLC has clear separations between teams and sequential phases. DevOps removes silos through cross-functional teams and continuous iterations.

  • What are some common DevOps tools?

Know key tools like Git, Jenkins, Docker, Ansible, Nagios, AWS, and Kubernetes. Focus on the 1-2 you have hands-on experience with.

  • What is infrastructure as code and how does it help?

Explain that IaC automates config through code, enabling easier management as infrastructure scales up.

  • What is continuous integration?

Highlight that CI automates merging developer code changes frequently to catch issues early.

  • Why is test automation important in DevOps?

Emphasize it speeds up delivery and reduces defects by systematically testing each build.

  • How can DevOps support agile development?

Point out that iterative releases and constant feedback loops in DevOps align with agile values.

  • What DevOps metrics would you track?

Discuss measuring deployment frequency, lead time, defect rates, and system uptime.

Demonstrating this foundational knowledge is key for junior roles. Make sure you can explain these concepts clearly and concisely.

Assessing Your Coding Skills

While coding questions won’t be as intense as for a software developer role, you will still need to demonstrate logical thinking and problem-solving. Some sample questions include:

  • How would you troubleshoot a bug in a DevOps pipeline?

Outline methodically reproducing the issue, checking logs for clues, and reviewing recent changes. Show your systematic approach.

  • How would you optimize a slow-running CI/CD pipeline?

Discussparallelizing tasks, reducing dependencies, and upgrading resources.

  • Write a simple script to check a server’s uptime.

Showcase basic coding skills and syntax as you pseudocode a script to ping a server and return a pass/fail uptime result.

  • What are some advantages of breaking applications into microservices?

Microservices are easier to maintain, scale, and update independently. Highlight benefits like flexibility and resiliency.

The goal is assessing your coding foundations – not expecting advanced algorithms. Show both your development skills and communication ability inmapping your approach.

Discussing Your Experience

While junior roles don’t expect years of experience, highlight any internships, personal projects, or academic work.

  • Walk me through a DevOps project you’ve worked on.

Choose a representative project and discuss the tools used, your responsibilities, challenges faced, and deliverables.

  • How did you pick up new skills needed for the project?

Show your self-starting ability to learn new tools quickly through documentation, tutorials, and experimentation.

  • What challenges did you face around communication and collaboration?

Share how you bridged gaps between teams, documented work, and actively sought feedback.

  • How did you prioritize tasks and manage your time?

Demonstrate your organizational skills in keeping tasks moving amid competing priorities.

Use these questions to showcase professionalism beyond just technical abilities – communication, time management, and adaptability are key!

Fielding Scenario-Based Questions

Scenario questions evaluate your critical thinking and real-world application of concepts. Some examples:

  • How would you troubleshoot an application that is crashing?

Outline steps like reviewing logs/stack traces, replicating issue, debugging failing components, and rolling back recent changes.

  • A new app version is running slowly. What steps would you take?

Discuss monitoring resource usage, load testing, optimization of slow areas, and updating infrastructure capacity.

  • Your CI/CD pipeline is failing. What do you do?

Highlight reviewing recent changes, re-running builds to pinpoint failure points, checking for environment issues, and notifying relevant teams.

  • A security vulnerability is discovered. How should it be addressed?

Discuss patching immediately, identifying affected components, scanning for potential exposure, and adding more security tests.

Don’t just state what you would do – walk through your methodology in detail. This shows how you put concepts into practice.

Standing Out as a Junior Candidate

While you likely won’t have years of professional experience, you can still stand out by:

  • Demonstrating genuine passion and interest in DevOps principles

  • Showcasing strong foundational knowledge of popular tools and technologies

  • Highlighting great communication skills and ability to collaborate effectively

  • Outlining your ability to independently learn new tools and skills quickly

  • Asking thoughtful questions that show your engagement

  • Exhibiting great problem-solving skills and work ethic

Employers want junior candidates with the right foundations who are eager to grow in DevOps. With the right preparation, you can absolutely highlight these key qualities in your interview!

11 What is virtualization, and how does it connect to DevOps?

Virtualization is creating a virtual version of something, such as a server, storage device, or network. Virtualization in DevOps lets teams make and control virtual environments that can be used for testing, deploying, and developing. This can help improve efficiency, reduce costs, and enable greater flexibility and scalability.

2 What is Continuous Testing?

Continuous Testing is the process of running automated tests as part of the software delivery pipeline. This gives you real-time information about the business risks in the latest release. Every build is tested in this way so that step-switching doesn’t go wrong in the software delivery lifecycle and so that development teams can get feedback right away. This makes developers much more productive because they don’t have to run all the tests again after every update and project rebuild.
