The prompt

You are designing a browser-based operations dashboard for support agents. They watch order status changes, fraud flags, and queue counts in near real time. Most user actions are still normal HTTP requests such as approve, refund, escalate, and add notes. The interviewer asks whether you would use Server-Sent Events or WebSockets for the live update channel.
