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.
| Framework | Notable focus |
| LangGraph | Cyclical graph-based orchestration with explicit nodes and conditional edges |
| LangChain | General-purpose framework for chaining LLM calls, tools, and retrieval |
| CrewAI | Role-based multi-agent collaboration with defined agent responsibilities |
| AutoGen | Multi-agent conversation and orchestration framework |
| Semantic Kernel | Enterprise-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.
