If interviewers ask this question, the company either currently utilizes open source technology or is considering it for the future. If you do have experience using it, mention the specific ones you have worked with. In addition, be sure to also indicate if you have experience modifying the open source programming code. In the event you have not personally faced challenges using it, mention any potential cons you know of to using open source technology.

"My experience using open source technology has been positive. I have used both MySQL and Hadoop without facing major challenges. However, I understand that using open source technology can have some general disadvantages including the lack of formal user support, as sometimes you have to rely on advice from user forums to address any issues you may have. Also, in most cases, open source developers don't put a lot of resources into the user interface, so some may find it difficult to learn how to use it."
