Practise describing REST endpoints, status responses, validation and authentication boundaries.

Write tests for a small service, including invalid input and dependency failures.
Prepare to trace one bug from its visible symptom to its root cause.

Common mistakes

Reciting framework commands without explaining the request and data flow.
