AI / Agentic AI Interview Questions

What are the popular frameworks used to build AI agents?

Several frameworks have emerged to help developers build agentic systems, each with a somewhat different focus.

FrameworkNotable focus
LangGraphCyclical graph-based orchestration with explicit nodes and conditional edges
LangChainGeneral-purpose framework for chaining LLM calls, tools, and retrieval
CrewAIRole-based multi-agent collaboration with defined agent responsibilities
AutoGenMulti-agent conversation and orchestration framework
Semantic KernelEnterprise-oriented framework integrating agents with existing application code

Most of these frameworks converge on the same underlying primitives, planning, memory, and tool invocation, but differ in how explicitly they let developers control the flow of execution versus leaving decisions to the model.

Which framework is known for cyclical, graph-based orchestration with explicit nodes and edges?
Which framework emphasizes role-based multi-agent collaboration?
