Staff Development Coordinator Interview Questions

30,013 staff development coordinator interview questions shared by candidates

We are building a real time group chat app that consists of a backend server and a frontend web app. Our MVP needs to support multiple users joining a group. When a user is part of a group, that user should be able to send a message to all other users in the group and read all messages posted in the group. How would you design this group chat application, specifically what protocol(s) could be used to communicate between our server and client web app?
