Are you comfortable working with open-source software?
Open-source software is a controversial subject. Some organizations will not allow any use of open-source software due to its vulnerability to malicious hackers and programmers. Other companies embrace it because of its cost benefits and the community's efforts to continually upgrade the applications. Interviewers will ask you about this to understand your position on this subject and determine if it aligns with theirs.
When preparing for an interview, find out whether the company embraces the concept of open-source software. Knowing this will help you craft your answer to this question. You don't necessarily have to agree with the company's policy. If you disagree, you should be able to defend your position based on your experience and knowledge of the vulnerabilities and benefits of open-source software. Keep in mind that the interviewer may be asking you this question because they are considering adopting new policies related to this topic.
"I am a supporter of open-source software. I believe open source products tend to be more innovative, are constantly being updated and improved, and can be obtained at lower costs. I have even contributed to developing and improving open source products. Based on my research, I noted that your organization has recently begun to adopt open source software for some of the applications. I'm confident I can assist you in selecting and managing open source applications that will benefit the company's operations."
