This article discusses a popular food delivery service named DoorDash that has saved the lives of millions of hungry people around the world, who either find cooking a sort of abomination, or are just not in the mood to cook, but are starving and can't wait :). The intended audience for this article is software engineers who are interested in designing systems.
During the process, candidates are expected to ask clarifying questions and think through every component, including the data model, keeping scalability, redundancy, fault tolerance, etc in mind. The candidate is given an example of a popular system and asked to brainstorm a design for the same.
