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.
