Critical Thinking and Edge Cases Questions

Ability to think beyond stated requirements to identify edge cases, boundary conditions, and potential failure scenarios. This includes adopting different user perspectives to anticipate how diverse users might interact with a system, surfacing unusual or extreme inputs, and predicting system behavior under stress or unexpected sequences. Candidates should demonstrate structured problem solving, attention to detail, risk identification, and suggestions for preventative testing or safeguards. Examples of assessed skills include enumerating edge cases, describing how to reproduce and mitigate failures, prioritizing risk based on likelihood and impact, and explaining trade offs between correctness, performance, and complexity.
