Requirements for Facebook
Learn about all requirements of Facebook.
We'll cover the following
In this lesson, we’ll list the requirements of Facebook. This is a very crucial step as requirements define the scope of a problem, so getting them right from the interviewer and understanding them well will make the design of the rest of the system smooth and easy.
We’ll use the notational convention to identify each requirement with a unique label "Rn", where "R" is short for Requirement and "n" is a natural number.
