75 DevOps Interview Questions And Sample Answers (With Tips)
Updated 12 September 2023
The technical interview is an essential step in any software development hiring process. In a DevOps interview, the questions can range between technical topics and the transferable skills that qualify you for the job. If you are getting ready to interview for a DevOps role, consider reviewing technical, situational and behavioural questions. In this article, we explore examples of DevOps interview questions with some examples to help you prepare for your interview.
4 Example DevOps Interview Questions And Answers
Use the following example interview questions and answers about your DevOps experience to help you prepare:
1. What experience do you have in DevOps?
This common question helps interviewers assess how your skills and expertise fulfil the job requirements. Give examples of the degrees, certifications and other qualifications you have that are relevant to the job description and can distinguish you from other candidates.
Example: "I have a bachelor's degree in software engineering and am currently studying to obtain my AWS engineer certification. In my previous role, I was responsible for forming and overseeing many of the projects the DevOps team completed, and I am confident this experience can be an asset to the team."
2. What are your favourite DevOps tools?
Software developers and engineers must have strong proficiency with an array of tools when implementing DevOps methodologies. Give examples of the tools you have experience with and how they have supported your success in the past.
Example: "The testing framework I have the most experience with is Selenium, however, I enjoy using Jenkins for combining building, testing and deployment processes. I also favour Git when working in paired programming environments, as it allows for collaborative coding in software development."
3. How do you ensure effective team collaboration?
DevOps requires consistent and open collaboration and shared working environments, so interviewers may use this type of question to evaluate your ability to understand others' ideas, communicate effectively and support team goals.
Example: "In my previous role, I would meet with my teammates to discuss the parameters of new projects. During these meetings, we established plans for progress evaluation, conference schedules and informal communication procedures for support purposes."
4. Describe a time when you managed both development and operational processes.
DevOps combines practices from both development and operational teams in an IT department, and the interviewer may want to understand how you applied your leadership skills to direct effective processes between both teams. Describe your experience with planning workflow, gaining input and delegating team roles.
Example: "I have not yet had the opportunity to combine my leadership role between both the operational and development teams. However, my previous employer allowed me to spend my last two weeks mentoring with him to develop my ability to delegate operations and integration and oversee the processes of both aspects of a DevOps team. With this experience, I am excited to have the opportunity to develop further within your organisation."
What Skills Are Necessary For DevOps?
DevOps professionals rely on a combination of technical knowledge and transferable skills to be successful. Their technical skills are highly essential in the development processes and operational management of software engineering projects. Aside from technical expertise and qualifications in software development and computer science, DevOps positions also require:
Research and analysis skills
Interpersonal and communication skills
Creativity and problem-solving skills
Ability to remain flexible and adaptive in fast-paced environments

The following steps show you how to get ready for a DevOps interview:
Research the company. Review the organisation's website to learn about current projects or challenges you can contribute to and discuss these during your interview.
Prepare a portfolio. Share a brief portfolio of work to highlight your most successful software builds using the DevOps methodology.
List questions to ask. Make a list of questions to ask at the end of your interview to learn more about specific expectations, compensation and other details about the role.
