How would you accelerate the response time of a website you created for us here at Coinbase?
When conducting an interview, hiring managers like the ones at Coinbase are interested in one of three things - how you can help their organization make money, save money, or save time. The questions they ask will be specific to these objectives. You can prepare for the interview by understanding the organization's mission, the role of the job you are interviewing for, and how you can help them achieve one of these three objectives. In this case, the interviewer is seeking to understand how you can save time.
"There are several ways you can accelerate the response time of a website. These include using adaptive images, employing a cache, minimizing the number of plugins you use, compressing the content, and enabling HTTP to keep-alive response headers. The methods I use depend on the specific application and how the users interact with it."

Anonymous Answer
Many things can optimize a website. Prioritize the first scroll content and make the other statics async. Better adaptive images depending on the screen size. Using correct HTTP header cache and Keep-alive mechanism so no overhead of multiple connections and handshake to the server is used. Serving SSR HTML in the case of React (or SSG) instead of waiting for it to download before showing content. In case of repeated access, having a service worker well configured is key to having fresh access again.
