• Defect Management – Categorizing bugs accurately by severity and priority and managing communication throughout the defect lifecycle.
• Advanced concepts (less common) – Designing risk-based testing strategies for legacy system migrations and validating complex marketing automation workflows.

Example scenarios:

• "Given a requirement document for a new telecom billing feature, walk me through how you would perform a static review and draft your initial test scenarios."
• "Explain how you would approach testing a system when there is minimal documentation available."

API Testing & Integrations

Modern applications rely heavily on microservices. You must demonstrate that you can confidently test APIs independently of the front-end user interface.

Be ready to go over:

• API Basics – Understanding REST architecture, HTTP request components (headers, body, parameters), and response structures.
• Validation Techniques – Verifying response status codes, payload data integrity, response times, and header information.
• Automation of APIs – Writing automated API assertions using libraries like RestAssured or building collections in Postman.
• Advanced concepts (less common) – Mocking third-party API dependencies, testing database state changes post-API execution, and security testing of endpoints.

Example scenarios:

• "How do you handle dynamic data dependencies where the output of one API is required as the input for another in an automated suite?"
• "Draft a test plan for validating a payment gateway API, including negative and edge cases."
