What employers mean

You should be able to…

  1. Build a clickable or working prototype without waiting for an engineering sprint
  2. Use an AI coding assistant to scaffold a working demo from a product spec
  3. Wire an LLM API into a simple Streamlit/Gradio UI to test a concept with real users
  4. Prototype in a prompt playground before committing to a build
  5. Use no-code tools to fake the backend so the front-end story can be user-tested
  6. Iterate a prototype same-day based on stakeholder or user feedback

Needs first: Explain how LLMs work and where they fail

Practice

Deployed prototype: a payment-dispute triage assistant

Build a Streamlit or Gradio app where someone pastes a payment complaint in their own words and gets back a structured classification — fraud, failed-but-debited, merchant issue — plus a drafted complaint message, powered by an LLM API. Write your own test set of 30 complaints (or generate them with a chat model), so the project never needs access to anyone's real transaction data. Scaffold most of the code with an AI coding assistant, ship it to a live URL, and put it in front of three people outside your circle.

Start from

30 payment-complaint descriptions you write or generate with a chat model, spread across fraud, failed-but-debited and merchant-dispute cases

Milestones
  1. Write the 30-complaint test set and the JSON schema the app must return · ~1h
  2. Scaffold the Streamlit/Gradio app with an AI coding assistant and get it classifying locally · ~1h
  3. Deploy to a public URL and run all 30 cases against the live app · ~1h
  4. Collect feedback from three outside testers and ship one change from it · ~1.5h
Done when
  • App is deployed to a public URL (Streamlit Community Cloud, HF Spaces, or similar) and works end to end
  • At least 3 external testers used it and gave feedback, documented in the README
  • README states which parts were AI-assisted and roughly how long the build took
  • One iteration based on tester feedback is visible in git history
Prove it

Evidence a recruiter can check

  • A live URL a stranger can open and use with you nowhere near it
  • The 30-case test set with the deployed app's classification for each, so the error rate is visible rather than claimed
  • Feedback notes from three testers outside your circle, and the commit that changed the app because of them
  • A README stating which parts the AI assistant wrote and how many hours the whole build took
Signal it

Shipped a live LLM-powered dispute-triage app in a weekend with an AI coding assistant — tested on 30 cases, put in front of three outside users, and iterated on their feedback.

Interview

Questions you'll get asked

  1. Tell me about a prototype you built without an engineering team — what tools did you use?
  2. How would you validate a new AI feature idea before asking engineering for a sprint?
  3. Walk me through how you'd use an AI coding assistant to build a working demo in an afternoon.
  4. What's the difference between a prototype meant for user testing and one meant for a stakeholder demo?
  5. How do you decide when a prototype is 'good enough' to hand off to engineering?
