Reviews

This course prepares you for a system design interview by using a case study of DoorDash (a prepared food delivery system) and familiarizes you with the challenges you will encounter during the interview. You will begin by understanding the theory behind the system design interview to give you an idea of what to expect. Next, you’ll understand how to identify a system’s requirements, handle data, and lay down the architecture of the system. Along the way, diagrams and quizzes will help you solidify your concepts. By the end of this course, you will have a solid understanding of how to approach a system design interview, and you will have the confidence to answer a number of different scenarios, no matter the question.

"You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it."
