Treat the following questions as a kind of cheat sheet based on hours of research. The questions may seem a bit generic, but they are pretty close to what you can expect in the real deal.
Ready to develop some compelling and thoughtful responses that will blow your interviewers away?
1. How important is security to your DevOps process? How have you promoted increased security awareness in the past?
If you've been paying attention, you know that security is a big issue in DevOps. Because DevOps automation works at a breakneck pace, it can include some glaring security flaws if you're not careful. As a DevOps engineer, it is in your job description to work to secure applications .
2. What technologies do you want to be exposed to in the future and why? Have you taken any active steps to get involved in these technologies?
What technologies do you want to be exposed to in the future and why? Have you taken any active steps to get involved in these technologies?
Truth be told, if you weren't expecting a question like this from a DevOps interview, then you've lost the plot, buddy. Innovations are a DevOps thing, just like emerging technologies.
That is why it is a good idea for you to join a technical community (Reddit or GitHub, for example) and become part of open source projects, etc. Keep your finger on the pulse of change, so to speak.
3. Tell us about how you implemented an efficient monitoring solution for a production system.
Follow-up takes time and patience and is difficult. A good DevOps candidate should know. There are a ton of things you can include in this type of response, like how to strike the fine balance between meeting SLAs, getting sleep, and not taking too much of the release cycle. Start preparing for these types of questions by Googling SRE monitoring strategies and reading up on the topic .
4. What do you think is the most challenging aspect of a DevOps role?
This is an "I" question if there ever was one. A question like this - one that asks for your opinion - is designed to give you an opportunity to speak openly about the challenges you have faced and overcome.
Companies are looking for candidates who enjoy facing challenges head-on, with a positive attitude. Also, you can talk about a business-related challenge or technical hurdle.
5. How would you describe continuous integration and how would you implement it?
6. How would you define DevOps?
A question like this is too open to have a correct answer. It is designed to reveal your mindset about the DevOps culture. The answer to this question really depends on your opinion of DevOps - is it about collaboration, automation, or speed?
But be sure to include some of the latest trends you expect in DevOps from your perspective, be it microservices or anything else. Also (here's a hint) DevOps is very much about collaboration, but its main goal is to streamline the development cycle, so DevOps is mostly about time.
7. What does "infrastructure as code" mean to you and how does the idea of IaC fit into the DevOps culture?
Remember when we talked about IaC and said that it allows an engineer to test infrastructure in the same way that they would test code? IaC is key to improving the overall automation strategy of many companies: the bridge that allows infrastructure management with minimal human intervention. Also, depending on your job description and organization, you may want to beef up your answer to include container technology and infrastructure automation tools.
8. How do you judge success, in the context of you and the DevOps team as a whole?
The DevOps culture is about a general improvement. All team members are working to make the production and deployment process safe, efficient, and of course automated.
That means that nothing can be done, there is always something that can be improved. As a DevOps engineer, your job is to constantly push yourself and your team to do better. And that's exactly why you need measurable or measurable goals to measure success. Otherwise, you would not know how to measure your success.
9. Why do we need DevOps?
This one's simple: Businesses are facing ever-increasing demand from users to deliver better and faster applications. And DevOps, with its emphasis on automation and collaboration, can help companies meet that demand cost-effectively and quickly.
10. What is the duty of a DevOps engineer regarding agile development?
DevOps engineers must work closely with Agile development teams to foster the kind of environment necessary to support practices such as continuous integration, continuous delivery, and automated testing. A DevOps engineer must work with the developers to keep all the DevOps machinery running smoothly.
