Questions you could be asked

  1. How do you structure and test a prompt to get consistent output from a language model?
  2. Walk me through a computer vision problem you solved, from raw data to a deployed model.
  3. What NLP problem have you worked on, and how did you measure whether it actually worked?
  4. What's a project where you used LangChain hands-on?
  5. Walk me through how you've used LangGraph in your day-to-day work.

Adapt your resume

  • List these exact terms on your resume: Prompt Engineering, Computer Vision, Nlp, LangChain, and LangGraph. 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.
