Google web developer interview questions can be challenging. Google interviewers often test your knowledge and skill with unique and well-crafted questions. For a web developer, that translates to skills like HTML, CSS, SQL, PHP/Ruby/Python, and JQuery. There’s no substitute for actual skill here, rote memorization of standard question-solving patterns is neither worthwhile nor what they are looking for.

To reduce the page load time, we can reduce the image size, remove unnecessary widgets, reduce lookups, minimize redirects, and use caching and HTTP compression. We can also place CSS at the top and script reference either at the bottom or in external files.
