The Brief

What you'll do, and what you'll demonstrate.

Build an internal reporting agent that chains 4 tools correctly and survives a 60-question evaluation harness.

This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.

When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."

Earning criteria — what you'll demonstrate

  • Implement tool-calling and multi-step reasoning in an agent framework
  • Design tool schemas that an LLM can call reliably
  • Build an evaluation harness that catches tool-call hallucinations
  • Communicate agent architecture and trade-offs in writing
