AI Research Engineer Interview Questions — sample questions
Design a multi-agent research system (EXPLAINED)
Multi-agent orchestration is a senior/staff-level system design question gaining traction at Google DeepMind and Microsoft. Learn the supervisor pattern, shared state management, and how to avoid the 'too many agents' anti-pattern that sinks most candidate answers.
Read full explanationMulti-Agent Graphs with Supervisor Pattern in LangGraph (EXPLAINED)
**Supervisor pattern** Central node decides next worker or FINISH based on plan and worker outputs — alternative to flat handoff messages.
Read full explanationParallel Node Execution in LangGraph (EXPLAINED)
**Parallelism model** LangGraph can schedule independent nodes in same superstep concurrently — e.g., search three sources at once. Reducers combine outputs into unified state field.
Read full explanationSubgraphs and Modular Agent Graph Composition (EXPLAINED)
**Why subgraphs** Parent graph orchestrates; subgraphs own domain logic — billing dispute flow, code review pipeline. Teams ship subgraph versions independently.

Hard AI Agents interview question on google interview: multi-agent search system — architecture, trade-offs, eval, and production patterns.
Read full explanationResearch Agent with Citations (ANSWERED)
Medium AI Agents interview question on research agent with citations — architecture, trade-offs, eval, and production patterns.
Read full explanationSwarm vs Supervisor Multi-Agent Design (ANSWERED)
Medium AI Agents interview question on swarm vs supervisor multi-agent design — architecture, trade-offs, eval, and production patterns.
Read full explanationContext Windows: Limits, Lost-in-the-Middle, and Long-Context Myths (ANSWERED)
Scenario question on context windows — token budgets, lost-in-the-middle bias, and why RAG still matters despite 1M-token claims.
