Sample interview questions: How do you prioritize performance optimization and loading times in your designs?
Sample answer:
-
Prioritize critical assets: Focus on optimizing the loading of essential resources like critical CSS, visible images, and above-the-fold content. Prioritize the assets that have the biggest impact on the user’s initial experience.
-
Minimize HTTP requests: Reducing the number of HTTP requests can significantly improve loading times. Use techniques like CSS sprites, font consolidation, and minification to combine multiple files into fewer.
-
Use lazy loading: Implement lazy loading for images, videos, and other non-critical content. This technique delays the loading of these elements until they are visible in the viewport, reducing the initial page load time.
-
Optimize image sizes: Compress images without sacrificing visual quality to reduce their file size. Use proper image formats (e.g., JPEG, PNG, WebP) and consider using a content delivery network (CDN) to deliver images efficiently.
