Questions you could be asked

  1. How do you structure and test a prompt to get consistent output from a language model?
  2. How would you design a retrieval step so the model answers from real data instead of guessing?
  3. How do you decide that one model's output is better than another's for a given task?
  4. Tell me about a project where genai was part of your work. What did you do?
  5. Tell me about a project where agentic ai was part of your work. What did you do?

Adapt your resume

  • List these exact terms on your resume: Prompt Engineering, RAG, AI Evaluation, Genai, and Agentic AI. An applicant tracking system matches the wording, not the idea.
  • Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
  • Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
