Outline a structured problem-solving approach you would use in a FAST IC interview.

• A. Ask for hints from interviewers and no plan.
• B. Clarify problem, state assumptions, outline plan, propose alternatives, reason through trade-offs, present solution, and verify with edge cases.
• C. Jump to solution, implement without constraints, then test later.
• D. Start with optimization.

Answer: (B)

A structured, methodical problem-solving approach in a FAST IC interview starts with clarifying the problem and setting the scope. You confirm the goal, lay out assumptions, and identify constraints so everyone is aligned. Then you outline a plan—a clear sequence of steps or approaches you would try, with milestones and how you’ll know you’re on track at each stage. Next you examine alternatives and weigh trade-offs, such as time, complexity, and risk, choosing a path that balances correctness with practicality. After that you present the solution in a coherent, testable way and verify it using edge cases and simple checks to ensure it handles unusual inputs gracefully. This flow shows you can think clearly under ambiguity, communicate your process, and own the approach from understanding to validation, which interviewers look for._rows
