Potential Minefields
How to avoid some common minefields when answering this question in order to not raise any red flags
- Lack of experience: If the candidate has no experience or limited experience with version control systems and their integration in DevOps, it may raise concerns about their ability to effectively collaborate and manage code in a DevOps environment
- Limited knowledge of different version control systems: If the candidate is only familiar with one specific version control system and lacks knowledge of others (e.g., Git, SVN, Mercurial), it may indicate a lack of versatility and adaptability in working with different tools
- Inability to explain integration with DevOps: If the candidate cannot clearly articulate how version control systems are integrated into the DevOps workflow and their role in enabling continuous integration and deployment, it may suggest a lack of understanding of DevOps principles and practices
- No experience with branching & merging: If the candidate has not worked with branching and merging strategies in version control systems, it may indicate a lack of experience in managing complex codebases and collaborating with multiple developers
