Company: Glean
Role: Software Engineer
Category: Software Engineering Fundamentals
Difficulty: medium
Interview Round: Technical Screen
Overview: This question evaluates a candidate's ability to design a test strategy for an ambiguous, open-ended system rather than write code. It tests skills in scoping requirements, identifying an oracle problem for hard-to-verify outputs, and structuring functional, boundary, negative, and non-functional test categories. It is commonly used in software engineering fundamentals interviews to assess conceptual reasoning about quality assurance and testability.
