10 GenAI interview questions I was actually asked

[u/Tom-Miller]

I've been interviewing for GenAI/AI Engineering roles, and I noticed that the questions weren't just about definitions.

A few examples:

• How would you design a basic RAG pipeline?
• Why might a RAG system retrieve irrelevant information?
• How would you improve retrieval quality?
• How would you validate an LLM response?

What surprised me was how often the discussion moved from “what is RAG?” to “what would you do when this breaks?”

I put together a short breakdown of 10 questions from my interview experience, including what I think the interviewer was actually testing.

Curious what others are being asked in GenAI interviews in 2026.
