This course compiles a comprehensive range of questions that are most likely to be asked during the frontend interview. Where many interview prep courses focus on data structures and algorithms, this course focuses on a variety of topics from network security to system design.

In this course, you will solve interview questions that cover general aspects of web development. You’ll start by going over network security and optimization techniques for load balancing and browser rendering. After that, you’ll move on to interview questions around SEO, APIs, and system design.

Overall, these are questions that are often overlooked, but they can really make you stand out from your peers. By the end of this course, you will have the confidence and ability to go in and ace that interview.

## Reduce time to first byte

In addition to the amount of time it takes for your page to fully load, you’ll also want to take a look at the amount of time it takes to start loading.

Time to first byte, or TTFB, is the amount of time a browser has to wait before getting its first byte of data from the server. Google [recommends](https://developers.google.com/speed/docs/insights/Server
) a TTFB of less than 200 ms. 

Here’s a snapshot of the 'timings' tab that gets shown when a response file on the network tab of devtools is clicked. It shows a website that has an excessive TTFB.
