This question is a great way to determine the applicant’s level of comfort with open source software. Open source software is free and available for anyone to use, modify or distribute. Proprietary software is typically developed by private companies that sell licenses to users.

Open source software has many benefits, including lower costs and increased security. However, it can be more challenging to troubleshoot than proprietary software. If you’re hiring an application administrator, you may want someone who is comfortable working with open source software. You should also consider whether your company would benefit from using open source software.

Example: “When it comes to software, I prefer to use open source whenever possible. Open source software is often more cost-effective and can be customized to meet the specific needs of a project or organization. It also allows for greater collaboration between developers, as they are able to share their code with each other and build on top of existing solutions. Furthermore, open source software typically has better security than proprietary software, since its code is available for review by anyone who wishes to do so.

At the same time, there are certain situations where proprietary software may be preferable. For example, if an organization requires specialized features that are not available in open source software, then proprietary software may be the best option. In addition, some organizations may require additional support from the vendor, which is only available with proprietary software.”

23. What strategies do you use for system optimization?

This question can help the interviewer understand your technical skills and how you apply them to improve systems. Use examples from previous experience to highlight your ability to analyze a system’s performance, implement changes and monitor results.

Example: “When it comes to system optimization, I believe in taking a holistic approach. I start by analyzing the current system architecture and identifying any areas of improvement or potential bottlenecks. From there, I work with stakeholders to develop an action plan that addresses those issues. This typically includes implementing new technologies, streamlining processes, and improving communication between teams.

I also prioritize scalability when optimizing systems. By anticipating future growth and making sure the system is able to handle increased workloads, I can ensure that the system remains efficient and reliable over time. Finally, I regularly monitor performance metrics and make adjustments as needed to keep the system running smoothly.”

24. Are you comfortable working with multiple operating systems?

The interviewer may ask this question to determine your comfort level with working on multiple operating systems. This can be an important skill for application administrators, as they often need to work across different platforms and ensure their applications are compatible with them.
