For coding, the same old load balancer is used to distribute the load to customer support agents. So you have to design APIs to initialise with agents, set limits for each agent, assign work to the next agent, and get a list of next agents.

For system design, they ask the low level design, mostly DB schema of the chat-based system, groups, private chat, relay messages, etc., focusing on how you will store them in DBs.
