Generative AI is no longer just about using tools like ChatGPT, DALL·E, Copilot, Veo, or Sora—it’s about understanding how these systems actually work, which is exactly what interviewers test today. In this video, we cover the most important Generative AI interview questions, structured across three levels: Easy, Intermediate, and Hard, to help you progress from core fundamentals to production-grade AI systems. You’ll learn what Generative AI is, how it differs from traditional AI, key concepts like neural networks, Transformers, attention, tokenization, and Large Language Models, and how models such as GANs, VAEs, and Diffusion Models work internally. We also dive into advanced topics including RLHF, RAG architectures, latent space, Mixture of Experts, LLM evaluation, and real-world deployment considerations. These questions are designed to test conceptual clarity, system-level thinking, and practical understanding—skills that are now expected even in non-AI roles. If you want to go deeper and build real-world GenAI applications, explore the Applied Generative AI Specialization by Simplilearn in collaboration with Purdue University, a 16-week live online program covering LLMs, Agentic AI, RAG, LangChain, and hands-on projects using OpenAI, Azure AI Studio, and Hugging Face.
