I'm currently getting ready for DevOps interviews and want to make the most of my study time. DevOps combines various tools and concepts such as cloud services, CI/CD, containers, Infrastructure as Code (IaC), Linux, and networking. From your experiences, what areas do interviewers tend to focus on the most? If you could suggest one or two key areas to heavily focus on that would really help in interviews, what would they be and why? Also, are there common pitfalls candidates encounter during DevOps interviews that I should steer clear of? If there's anything else crucial that I'm overlooking, please share your thoughts!

I'd suggest you really concentrate on CI/CD design and pick one cloud provider to focus on (think IAM, networking, scaling). Make sure you can explain *why* you made particular design choices; a lot of candidates get caught up in just mentioning tools without solid fundamentals. That's a common issue!
It really depends on the specific role you're applying for. Some companies dive deep into development-related topics, while others focus more on platform aspects. Check the job specs to guide your study—make sure you understand the software development lifecycle (SDLC) and the fundamentals. The more interviews you can get under your belt, the better practice you’ll have!
In general, interviewers will drill down into the tech stack their team utilizes daily. It's crucial to have strong fundamentals in Linux and CI/CD pipelines—these interviews often test your troubleshooting skills, especially in production scenarios. Knowing how to debug failed deployments, read logs, and grasp basic networking is key. You should also be comfortable with containers and Kubernetes, so don't just stop at 'docker run.' Understand networking between containers, how resource limits play a role, and what happens when failures arise. While the specifics of cloud platforms are less important, you should grasp core concepts like IAM and managed services that are common across platforms like AWS, Azure, and GCP. The biggest mistake is memorizing tools without being able to solve real problems or articulate your reasoning. Interviewers can tell when someone can't explain their decisions or troubleshooting methods. Be ready to discuss real situations you've dealt with, even from personal projects!
Absolutely! Being able to walk through your thought process is crucial. If you want to practice explaining things better, check out interviews.chat to get feedback on how you articulate your answers.
