03 Prompt Engineering
Phase 1 - Foundations
Stage 3 of 14. Previous: Stage 2 - LLM Fundamentals. Next: Stage 4 - Agent Fundamentals.
Goal
Learn to write, test, and improve prompts that produce reliable agent behavior.
Learn
- Prompt Basics
- Writing Good Prompts
- Structured Outputs
- Prompt Testing
- How to specify role, task, context, constraints, and output format
Build
Build a prompt testing lab with several prompts, test inputs, expected outputs, and scoring rules.
Exit Criteria
- You can write prompts with clear role, task, constraints, and output format.
- You can test prompt changes instead of guessing.
- You can use structured output formats when downstream code depends on the result.
Test
Use the QAs: 03 Prompt Engineering to check your understanding of every topic in this stage.
Interview
For deeper study or hiring, use the interview pages with interviewer rubrics:
- Junior Interview: Prompt Engineering — friendly, example-driven questions for learners.
- Senior Interview: Prompt Engineering — open-ended, trade-off and design questions.
Checkpoint
