Discuss KPIs like lead time, defect removal efficiency, test coverage, open bugs, meantime to resolution etc. Link each back to specific process improvements or product quality insights.
Q: What challenges have you faced while testing applications that interact with external systems/services? How did you address them?
Reveal sophisticated thinking around challenges like incompatible APIs, dependencies, data consistency, and end-to-end flows. Demonstrate you can tackle intricate real-world complexities.
Q: Tell us about the most challenging troubleshooting scenario you’ve faced when testing a product before release. How did you isolate and address the issue?
Share an example that highlights your systematic, analytical approach along with tenacity. Discuss tools and processes leveraged during root cause analysis and remedy. Show you can address critical problems.
Testing Methodologies
Show expertise applying QA best practices from planning to defect prevention.
Q: Walk us through your typical test strategy development process from requirements to test execution.
Demonstrate a methodical approach spanning:
- Analyzing requirements
- Identifying scope, risks, priorities
- Selecting testing types (functional, performance etc)
- Developing test plans/cases
- Determining environment and data needs
- Managing testing cycles and progress tracking
Q: How do you ensure adequate test coverage across a large, complex system?
Discuss strategies like leveraging traceability matrices to map requirements, using modeling to identify complex flows, expanding test data sets to cover edge cases, applying code coverage tools etc.
Q: As a senior team member, how would you advocate adopting best practices like shift-left testing?
Highlight benefits such as finding defects earlier which reduces cost and shortens release cycles. Discuss getting leadership buy-in, piloting, transitioning QA upstream to engage earlier etc.
Q: How do you prioritize what areas get the most extensive/rigorous testing within schedule and resource constraints?
Explain considering factors like functional and data complexity, usage patterns, underlying infrastructure volatility, high-risk areas etc. when allocating testing time and effort.
