Answer
By concurrent garbage collection. Frame the concept in practical terms so you can explain it during interview discussion.
ZGC is designed to minimize 'Stop-The-World' pauses by performing most of its garbage collection work concurrently with the application threads. It uses colored pointers and load barriers to track object references without stopping the application. In scenarios demanding ultra-low latency, like real-time trading platforms, ZGC can be advantageous by keeping pause times under 10ms.
