💡 Quick Answer
- API manual tester roles require Postman collection design, test scripts, and Newman CI runs — not unorganized request tabs alone.
- Expect 14 core modules plus a phased real-time API testing project with mentor collection reviews.
- Basic HTTP concepts and software testing fundamentals should precede Module 1; coding helps but is not mandatory early on.
