Spent a solid chunk of time upfront clarifying the problem, which I think was the right call.
Start by clarifying the problem and constraints, then outline a brute-force solution before optimizing with appropriate data structures or algorithms. Walk through your thought process, discuss trade-offs, and implement clean, modular code while explaining each step.
Pro tip: At Google, interviewers value how you think more than just the final answer. Verbalize your reasoning, ask clarifying questions, and proactively discuss edge cases and potential optimizations.
Restate the problem in your own words and ask clarifying questions about input size, constraints, and expected output. Confirm assumptions before proceeding.
Discuss a brute-force solution first, then analyze its time and space complexity. Brainstorm optimizations using appropriate data structures or algorithmic paradigms.
Select the best approach based on trade-offs (time vs. space, simplicity vs. efficiency). Explain why it's optimal for the given constraints.
Write clean, modular code with meaningful variable names. Walk through a few test cases, including edge cases, to verify correctness.
State the final time and space complexity. Discuss potential improvements or alternative solutions, and reflect on any assumptions made.

Choose a specific, high-impact situation where your values or leadership directly influenced a technical outcome, such as navigating ambiguity or resolving a conflict. Use the STAR method to structure your story, ensuring you highlight your actions and the measurable results. Be prepared to dive deeper into your decision-making process and how you handled pushback.
Pro tip: Focus on a situation where you had to balance competing priorities or make a tough call that aligned with your values, and explicitly connect it to Google's core values like 'focus on the user' or 'don't be evil' (now 'do the right thing'). This shows cultural alignment and maturity.
Briefly describe the project, team, and the specific challenge or ambiguity you faced, ensuring it's relevant to software engineering at Google's scale.
Clearly articulate the conflicting viewpoints, unclear requirements, or ethical dilemma that required you to lean on your values or leadership.
Explain the steps you took, emphasizing how your values guided your decisions and how you influenced others or resolved the conflict.
Quantify the results if possible, and reflect on what you learned and how it reinforced your values or leadership style.
Anticipate deeper questions about your thought process, alternative approaches, and how you'd handle similar situations in the future.
