Top 15 Interview Questions for Generative AI Engineers (2025 Guide)

Generative AI is one of the fastest-growing fields in 2025. Companies are hiring Generative AI Engineers to design LLM pipelines, fine-tune models, and build real-world AI applications. Preparing well for interviews is key to landing these roles.

Here are the top 15 Generative AI Engineer interview questions and tips to crack them.

Technical Questions

  1. What’s the difference between GPT-style models and diffusion models?
  2. How do you fine-tune a large language model with limited data?
  3. Explain prompt engineering – what techniques improve response quality?
  4. How would you design a RAG (Retrieval-Augmented Generation) pipeline?
  5. What are common challenges in training generative models at scale?
  6. How do you evaluate the quality of generative outputs?
  7. Compare LoRA vs full fine-tuning.
  8. How do you mitigate hallucinations in LLMs?
  9. Explain the concept of embeddings and their role in semantic search.
  10. How would you deploy a generative model in production with low latency?

Behavioral & Problem-Solving Questions

  1. Tell me about a time you built an AI system that directly impacted business.
  2. How do you stay updated on fast-moving AI research?
  3. What ethical considerations must be made when deploying generative AI?
  4. How do you work with cross-functional teams (PMs, designers, data scientists)?
  5. Imagine you’re tasked with reducing inference cost by 40%. How would you approach it?

Quick Preparation Tips

  • Stay updated with OpenAI, Anthropic, Google DeepMind releases.
  • Brush up on transformers, embeddings, fine-tuning methods.
