Struggling with AI System Design Interviews

As the title suggests, I have been struggling with AI System Design Interviews. For reference, I am an experienced software engineer and have built multiple agents, but the issue is that the agents I have built don’t experience the issues that production grade agents have so often I find myself getting stuck answering the deep dives past the initial design. Are there resources out there for learning advanced agent system design? Sort of like the equivalent of “Design Uber” but instead it’s “Design Harvey”.
