What source control tools have you used?

Interviewers ask about source control tools to assess your technical proficiency and experience in managing code changes within a collaborative environment. It provides insight into your familiarity with industry-standard practices and tools, which is essential for ensuring version control and maintaining project integrity. They may also want to gauge how you handle collaboration and conflict resolution in a team setting, which can be critical when multiple developers are working on the same codebase.

Begin by listing the source control tools you have used, such as Git, SVN, or Mercurial, and briefly explain your experience with them. It's useful to mention specific projects where you effectively used these tools to manage code changes. For example, you could say, "I have primarily used Git for version control in my last role, where I contributed to an open-source project. I utilized branching strategies and pull requests to facilitate code reviews and maintain code quality while collaborating with a team of developers."
