I explained that in one of my previous projects, I faced a problem where a webpage design didn’t display correctly on different screen sizes. I analyzed the issue, found that the problem was related to inconsistent CSS rules, and solved it by using responsive design techniques with media queries and flexible layouts. I also mentioned how I tested the solution on multiple devices and collaborated with my team to ensure a smooth user experience. This showed my technical knowledge, attention to detail, and teamwork skills — all of which are important at Google.
