Questions you could be asked

Walk me through fine-tuning a model: what data did you use, and how did you check the result?
Walk me through how you've used OpenAI in your day-to-day work.
What are the limits of Claude that you've run into, and how did you work around them?
What's a project where you used Gemini hands-on?
Walk me through how you've used LangChain in your day-to-day work.

Adapt your resume

List these exact terms on your resume: Fine Tuning, OpenAI, Claude, Gemini, and LangChain. 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.
