In the previous video of this series, we designed a TinyURL-like system and detailed how to best answer system design interview questions. In this video we cover another example of system design questions, and that example is WhatsApp. We will lay out one possible design of a WhatsApp-like system, which could be used if asked about any chat messaging system during interviews.
