• 5. Can you walk me through your process of troubleshooting and debugging frontend issues?
  First, I analyze the issue by reviewing the code and checking for any error messages. If needed, I use debugging tools like Chrome DevTools to inspect the elements and identify the cause of the issue.

Technical Skills & Experience

• 6. How familiar are you with responsive design and how do you ensure your websites are optimized for different devices?
  I have extensive experience with responsive design and make sure to use flexible grids, media queries, and fluid images while coding. I also perform thorough testing on different devices and browsers to ensure a seamless user experience across all platforms.
• 7. What are some key elements to consider while optimizing a website for SEO?
  In addition to using relevant keywords and meta tags, it's important to have a well-structured and semantic HTML code, optimize image sizes, and use proper heading tags. It's also essential to have a mobile-friendly and fast-loading website.
• 8. How do you approach cross-browser compatibility issues?
  I start by using browser testing tools like BrowserStack to identify any compatibility issues. Then, I use vendor prefixes and polyfills to ensure my code works on different browsers. I also make sure to test my code on multiple browsers throughout the development process.
• 9. Can you explain the difference between front-end vs back-end development and how they work together?
  Frontend development deals with the presentation and user experience of a website or application, while backend development involves writing the code that runs on the server and handles the business logic of the website. Both are essential in creating a functional and user-friendly website.

  I use modern techniques like flexbox and grid layout, which have better support across browsers. If needed, I also use vendor prefixes and polyfills to ensure a consistent layout and design across different browsers.

Situational Questions

• 11. How do you handle a situation where a client requests a feature that conflicts with the project timeline?
  I understand that clients may have changing requirements and I communicate with them to understand the urgency and importance of the requested feature.

  I follow WCAG guidelines and use semantic HTML and alt tags for images. I also test my websites with screen readers and keyboard navigation to ensure they are accessible to all users. In case of any potential barriers, I work with my team to find solutions.
• 13. Can you describe a time when you had to find a creative solution to a technical problem?
  While working on a website, I encountered a Javascript conflict that was causing certain elements to not function properly. After trying multiple solutions, I realized that the issue was caused by a plugin. I then rewrote the code to achieve the desired functionality without using the problematic plugin, resulting in a more efficient and lightweight website.
