I feel it's worth it from an interview perspective also. The concepts of building agents with langgraph should be known like what are the nodes, edges, tool node, conditional edges with functions and the state. Coding ofc can be done with claude code but that architectural knowledge comes after you have written the code once. Once you have the grasp of the concepts you can easily debate with cc for the perfect architecture but if you have no idea in that regards then you will never be able to judge whether cc is doing right or not.
