Structuring Technical Interviews for Linux Administrator Candidates

After candidates pass initial Linux Administrator skills tests, it's time for technical interviews to assess their practical abilities. While skills tests help filter out unqualified candidates, technical interviews are key to identifying the best fit for your team. Let's explore some effective interview questions to evaluate Linux Administrator candidates.

Consider asking: 'How would you troubleshoot a server that's running out of disk space?', 'Explain the process of setting up a LAMP stack', 'What's your experience with containerization and Docker?', 'How do you approach system security and user management?', and 'Describe a complex Linux issue you've solved recently'. These questions help assess problem-solving skills, technical knowledge, and real-world experience in Linux administration.

What's the difference between a Linux Systems Administrator and a DevOps Engineer?

While Linux Systems Administrators and DevOps Engineers both operate within IT, their roles differ significantly. Recruiters often confuse the two because both involve managing system environments and require technical skills. However, their core responsibilities and focus areas set them apart.

A Linux Systems Administrator focuses on system maintenance, ensuring that servers and networks are stable and running smoothly. Their primary goal is to ensure system stability by managing servers and monitoring uptime. They often work with tools like Shell, Nagios, and Puppet, and possess skills in troubleshooting and configuration. Typically, they operate in server and network environments and hold certifications like RHCSA or CompTIA Linux+.

On the other hand, a DevOps Engineer is involved in automating and deploying software. Their main aim is to streamline software delivery, making processes more fluid and agile. They work extensively with tools such as Docker, Jenkins, and Ansible, focusing on scripting and continuous integration. DevOps Engineers usually work in both cloud and on-premises environments and often come with certifications like AWS Certified DevOps Engineer.
