Solved the main problem without any hints, covered edge cases, walked through examples, coded it up cleanly.
Start by clarifying the problem and constraints, then propose a brute-force solution before optimizing. Walk through your optimized approach with a concrete example, explicitly analyzing time and space complexity, and finally discuss edge cases and a follow-up extension.
Pro tip: At Google, interviewers value structured communication and the ability to iterate on feedback. After presenting your solution, proactively suggest a follow-up extension (e.g., handling larger inputs or adding a feature) to demonstrate depth and initiative.
Ask questions to understand input/output, constraints, and assumptions. Confirm edge cases like empty input, large values, or duplicates.
Outline a simple, naive solution and its complexity. This shows you can start somewhere and provides a baseline for optimization.
Propose an improved algorithm, explaining your thought process. Use a small example to illustrate how it works.
Clearly state the time and space complexity of your optimized solution, and compare it to the brute force.
Walk through edge cases and how your solution handles them. Then suggest a follow-up extension or variation to show depth.

Use the STAR method (Situation, Task, Action, Result) to structure your answers, focusing on specific examples that highlight adaptability and conflict resolution. Emphasize your thought process, the actions you took, and the measurable outcomes, while showing how you navigated ambiguity or resolved disagreements.
Pro tip: Choose examples where you made a tangible impact, and quantify results when possible. Also, briefly reflect on what you learned, demonstrating self-awareness and growth.
Briefly describe the situation and the task you were responsible for, providing enough background for the interviewer to understand the challenge.
Explain the specific ambiguity or conflict you faced, and why it was significant or difficult.
Walk through the steps you took to address the situation, emphasizing your reasoning, collaboration, and problem-solving skills.
Describe the results of your actions, including any measurable impact, and what you learned from the experience.
