πŸ’¬ Potential Interview Questions

    I follow consistent code styling, modular architecture, thorough documentation, and write unit/integration tests. I also leverage tools like ESLint, Prettier, and code reviews.

  3. Describe a mobile or web app you've built. What was your role and tech stack?
    I developed a task management mobile app using React Native and Firebase. I handled both front-end components and the real-time database integration.

  4. How comfortable are you working with both relational and NoSQL databases?
