Interview 1

This was a low level design round. Question asked was more like a chat application. But it was different in the sense that the chat is happening between user & a company. The company could be having employees who could join the conversation in the middle. Other extension was, what if we had to do message broadcasting. Data modelling was majorly asked & bonus questions on how you would implement it onto production given a good scale.
