I picked the right data structure and got the code mostly working on my own, which felt good.
Start by clarifying the problem and constraints, then discuss potential data structures and their trade-offs before coding. Implement the chosen solution cleanly, test with examples, and analyze time and space complexity.
Pro tip: Verbalize your thought process and consider edge cases early; Google values how you approach problems, not just the final code. If stuck, think aloud about simpler versions or related problems to show problem-solving skills.
Ask clarifying questions to confirm input/output formats, constraints, and edge cases. Restate the problem in your own words to ensure alignment.
Brainstorm suitable data structures (e.g., arrays, hash maps, trees, graphs) and discuss their trade-offs in terms of time and space complexity.
Choose the optimal data structure, outline the algorithm, and write clean, modular code. Explain your reasoning as you code.
Walk through your code with sample inputs, including edge cases. Debug and fix any issues.
State the time and space complexity of your solution and discuss potential optimizations or alternative approaches.

Start by clarifying the problem and edge cases, then outline a brute-force approach before optimizing. While coding, verbalize each step, especially the loop logic, and test with small examples to catch off-by-one errors.
Pro tip: Google values clean, efficient code and clear communication. Write pseudocode first to structure your thoughts, then translate to real code while explaining your reasoning.
Ask clarifying questions to confirm input/output, constraints, and edge cases. Restate the problem in your own words to ensure alignment.
Propose a brute-force solution and analyze its time/space complexity. Then suggest an optimized approach, explaining the trade-offs.
Write clean code while narrating your thought process, focusing on the loop construct and its invariants. Use meaningful variable names and modularize if helpful.
Walk through your code with a small example, including edge cases. Identify and fix any bugs, especially those related to loop boundaries.
State the final time and space complexity. Discuss potential optimizations or alternative solutions if time permits.
