Problem Solving and Communication Questions

Assess a candidate's structured approach to solving problems and their ability to communicate their thinking clearly, regardless of whether the problem is technical, analytical, or business in nature. Look for: clarifying requirements and open questions before diving in, explicitly stating assumptions, breaking a complex or ambiguous problem into smaller components, proposing and comparing multiple approaches, explaining trade offs in plain language, narrating reasoning step by step as the work progresses, verifying a proposed solution (including edge cases, failure modes, or counterexamples), and adapting the approach when new information or constraints appear. Emphasis is on logical rigor, the ability to adjust the level of detail for different audiences (technical peers vs non-technical stakeholders), and continual communication so the interviewer can follow the candidate's reasoning and decisions throughout.
