World Model Interview Questions: From JEPA, Genie, and Cosmos to VLA
This PDF is a structured interview preparation guide for candidates working on World Models, Physical AI, Vision-Language-Action models, embodied intelligence, autonomous driving, robotics, multimodal AI, and agentic systems.
 
It contains 120 high-frequency interview questions covering both foundational concepts and cutting-edge research directions, including:
World Model fundamentals, MDP/POMDP, latent states, transition models, model-based reinforcement learning, Dreamer, JEPA, I-JEPA, V-JEPA, V-JEPA 2, V-JEPA 2.1, LeWorldModel, Causal-JEPA, Genie, interactive world generation, World Foundation Models, NVIDIA Cosmos, Physical AI, autonomous driving world models, VLA driving world models, robotic world models, VLA-JEPA, spatial intelligence, 3D world modeling, Agentic World Modeling, counterfactual simulation, and world model evaluation.
 
This guide is not just a collection of isolated concepts. It is organized around one central question:
How can a model connect perception, prediction, action, planning, and counterfactual simulation into a unified intelligence system?
 
Each question follows a clear three-part structure:
1. Intuitive Explanation
Helps you explain the concept naturally in an interview.
2. Mathematical Derivation
Builds a more rigorous understanding beyond surface-level definitions.
3. Interview-Ready Summary
 
Provides a concise answer that you can directly adapt in real interviews.
This PDF is especially suitable for:
AI researchers, engineers, and students preparing for interviews in multimodal AI, VLA, autonomous driving, robotics, embodied AI, Physical AI, or agent systems;
candidates who want to understand how world models differ from video generation models, perception models, LLMs, and multimodal large models;
readers who want to build a systematic knowledge framework around World Models, JEPA, Genie, Cosmos, VLA, and Physical AI;
professionals preparing for technical discussions, research interviews, or advanced AI study.
 
If you are already familiar with LLMs, VLMs, and multimodal models, but still feel unclear about how World Models, Physical AI, VLA, JEPA, Genie, and Cosmos connect with each other, this guide will help you build a complete technical roadmap.
Best for: AI interview preparation, technical review, paper-reading support, world model learning, autonomous driving and embodied intelligence interview preparation.
