Technical practice
How would you design an end-to-end test architecture for a GenAI application?
What to coverThe role includes owning test architecture for LLM applications, RAG pipelines and AI workflows. Suggested answer focus: explain test layers, coverage across the software testing life cycle, and how you would balance fast checks against deeper evaluations.
How would you test a RAG pipeline when an answer is inaccurate?
What to coverHands-on RAG testing is specified in the posting. Suggested answer focus: describe checks that distinguish retrieval problems from answer-generation problems, using traceable test inputs and expected evidence.
How would you evaluate an LLM application's accuracy and reliability?
What to coverThe posting calls for LLM testing and AI model evaluation. Suggested answer focus: propose representative test cases, evaluation criteria and human review where automated judgments may be insufficient.
How would you validate a prompt change without missing regressions?
What to coverValidating prompt-engineering frameworks is a stated responsibility. Suggested answer focus: compare outputs against a versioned set of cases and explain how you would handle acceptable variation rather than relying solely on exact matches.
How would you structure Python tests for APIs and backend AI components?
What to coverThe role requires Python automation across APIs, backend services and AI components. Suggested answer focus: cover reusable test setup, integration boundaries, assertions and the trade-off between isolated and end-to-end tests.
How would you verify database-dependent results using SQL and Snowflake?
What to coverThe posting specifies hands-on SQL and Snowflake experience. Suggested answer focus: explain checks for data correctness and consistency, including how you would make test data and queries repeatable.
Which automated checks would you put in CI/CD, and when would they run?
What to coverIntegrating automated tests into CI/CD is a stated responsibility. Suggested answer focus: distinguish quick regression checks from slower AI evaluations, and explain how failures should be reported for investigation.
How would you choose automation and AI evaluation tools for this test framework?
What to coverThe posting mentions AI evaluation tools, frameworks such as LangChain, and integrating automation tools beyond Selenium. Suggested answer focus: compare tools by the interfaces they test, maintainability and suitability for evaluating AI behavior; avoid assuming any particular tool is already in use.
How would you assess performance and scalability for a cloud-based AI system?
What to coverThe role includes performance testing and scalable test frameworks for cloud-based AI solutions; security testing is preferred. Suggested answer focus: discuss representative workloads, response-time and reliability measures, and how you would investigate bottlenecks without assuming a specific cloud platform.
How would you investigate an intermittent failure in an AI test suite?
What to coverMonitoring results, analyzing failures and recommending improvements are stated duties. Suggested answer focus: separate application defects from test instability and variable model outputs, then explain what evidence would support a corrective action.
Behavioural practice
Tell me about a time you worked across teams to identify a quality risk.
What to coverThe role calls for collaboration with developers, data scientists and product teams. Suggested answer focus: give the situation, your actions to establish and communicate the risk, and the resulting decision or outcome.
Describe a difficult test failure you investigated.
What to coverFailure analysis and actionable recommendations are part of the role. Suggested answer focus: recount the symptoms, how you narrowed down the cause, what you recommended and the result.
Tell me about a time you had to prioritize testing under constraints.
What to coverThe posting spans API, integration, regression, performance and AI evaluation work. Suggested answer focus: explain the competing risks, how you chose coverage and what happened; this prioritization scenario is a preparation suggestion, not a stated employer process.
Describe a time you improved an automation framework.
What to coverDesigning, developing and maintaining automated frameworks is central to the role. Suggested answer focus: give the original limitation, the changes you made and evidence of their effect on test reliability or maintainability.
Tell me about a time you communicated uncertain test results to stakeholders.
What to coverThe role combines AI evaluation, result monitoring and cross-functional communication. Suggested answer focus: describe the uncertainty, how you presented the evidence and limitations, and the outcome of the discussion.
