Because of its all-encompassing nature, it’s natural to feel confused about DevOps at first. Initially, hiring a DevOps engineer may seem like a counterproductive measure, but once you understand the benefits, you’ll realise it’s a valuable investment.
DevOps is a comprehensive approach that involves collaboration between development and operations teams throughout the entire service lifecycle. It ranges from ideation and idea sketching to actual production of the service and encompasses all stages in between.
Software development encompasses various essential activities such as coding, testing, implementation and bug fixing. On the other hand, operations’ primary focus is maintaining the hardware and software infrastructure required to run the program and enabling available computational resources to be easily accessible.
Despite using the same technology, the lack of effective communication between development and operations teams is apparent. DevOps aims to bridge this gap by bringing these two traditionally separate engineering domains together, enhancing communication and collaboration between them.
DevOps aims to promote automation and monitoring at all stages of software development, from integration and testing to deployment and infrastructure management. The goal is to reduce the time and effort required to complete a product while improving the overall efficiency of the process.
A cohesive team is vital for businesses, yielding substantial benefits. According to a survey by automation tool vendor Puppet, companies utilising DevOps strategies can deliver code up to 30 times more frequently than those that do not, with 50% fewer failed deployments. This underscores the significance of having a unified team for operational efficiency.
The evidence suggests that your team can boost productivity, efficiency, and speed of delivery by hiring a DevOps Engineer. By working collaboratively, the process of program completion is accelerated, leading to increased value and the promotion of innovative ideas.

This could unlock a world of opportunities for your IT team.
Key Interview Topics for a DevOps Engineer
It’s evident that DevOps presents multiple benefits. However, hiring a DevOps Engineer can be challenging as there is no set path to this role. Additionally, since this role requires a high level of expertise, the pool of highly qualified DevOps Engineers is limited.
Before hiring a DevOps Engineer, let’s consider some questions you may ask to ascertain their expertise.
How is DevOps distinct from Agile?
However, Agile primarily concentrates on production methodologies, particularly those used in software engineering, and software created under Agile principles may be limited to certain contexts like testing. Nevertheless, with the incorporation of DevOps practices, your team can deploy software to the production environment with greater ease and security.
While Agile prioritizes code quality, DevOps additionally guarantees reliable software deployment.
Kindly elaborate on the widely used DevOps tools and the ones you have experience working with.
Numerous DevOps tools are available, but some of the more prevalent ones include:
- Git, a tool for version control of files,
- Jenkins, a technology for continuous integration
- Selenium, a tool for continuous testing.
- Puppet, Chef, and Ansible, which are tools for configuration management and deployment.
- Nagios, a tool for continuous monitoring.
- Docker, a tool for creating containers
It is not unexpected that a significant factor behind DevOps strategies is automation. Improved automation results in fewer errors and allows engineers to dedicate more time to the critical aspects of their work.
Therefore, when hiring a DevOps engineer, it is crucial to ensure their proficiency in most, if not all, of these widely-used technologies.
Demonstrate how all the components connect
With the growing demand for DevOps Engineers, organizations expect them to possess both a broader perspective of their role and an eye for detail. To succeed in their role, these Engineers must comprehend how each component of their work contributes to the overall objective.
