5. Describe your experience with version control systems (e.g., Git).

   • Answer: I'm proficient with Git, having used it extensively for [Number] years. My experience includes branching strategies (e.g., Gitflow), merging, resolving conflicts, using pull requests, and collaborating effectively on large projects using remote repositories like GitHub, GitLab, or Bitbucket.

6. What are your preferred methods for code review?

   • Answer: My code review process prioritizes clarity, maintainability, and efficiency. I focus on code style consistency, adherence to best practices, potential bugs, security vulnerabilities, and overall design. I provide constructive feedback, focusing on both the 'what' and the 'why' of suggested changes.

7. How do you handle conflicts with other developers?

   • Answer: I believe in open and respectful communication. I would strive to understand the other developer's perspective, clearly explain my point of view, and collaboratively find a solution that best serves the project. If necessary, I would escalate the issue to a team lead or manager for mediation.

8. Explain your approach to designing and implementing efficient algorithms.

   • Answer: I begin by clearly defining the problem and its constraints. I then explore various algorithm approaches, considering their time and space complexity. I evaluate the trade-offs and choose the most suitable algorithm for the specific context. I thoroughly test and optimize the implementation for performance.

9. What are some common design patterns you're familiar with and how have you used them?

   • Answer: I'm familiar with various design patterns, including Singleton, Factory, Observer, MVC, and others. I've used these patterns to improve code organization, reusability, and maintainability in projects involving [Specific examples of projects and how patterns were used].

10. How do you ensure the code you advise on is secure?

    • Answer: I incorporate security best practices throughout the development lifecycle. This includes input validation, secure coding techniques to prevent common vulnerabilities (SQL injection, cross-site scripting), and utilizing security tools and frameworks. I also advise on secure authentication and authorization mechanisms.

11. What is your experience with testing methodologies (unit, integration, system)?

    • Answer: I have extensive experience in all three testing methodologies. I'm comfortable writing unit tests using frameworks like JUnit or pytest, designing and executing integration tests to verify interactions between components, and performing system tests to validate the overall system functionality.

12. Describe your experience with Agile development methodologies (Scrum, Kanban).

    • Answer: I have worked extensively within Scrum and Kanban frameworks. I understand sprint planning, daily stand-ups, sprint reviews, and retrospectives. I'm familiar with Kanban boards and their use in visualizing workflow and managing tasks.

13. How do you handle technical debt in a project?

    • Answer: I advocate for proactively addressing technical debt by identifying and prioritizing it early. I use tools and techniques to track technical debt, and I work with the team to create a plan for addressing it in a sustainable manner, balancing immediate priorities with long-term maintainability.

14. What is your experience with databases (SQL, NoSQL)?

    • Answer: I'm proficient with both SQL and NoSQL databases. I have experience with relational databases like MySQL, PostgreSQL, and SQL Server, and with NoSQL databases like MongoDB and Cassandra. I understand the strengths and weaknesses of each type and can choose the appropriate database for a given project.
