Spent a chunk of time clarifying edge cases and talking through the general approach before writing anything.
Start by restating the problem and clarifying constraints and edge cases with the interviewer. Then outline a high-level algorithm with time/space complexity before writing clean, modular code. Finally, test with examples and discuss potential optimizations.
Pro tip: Think out loud continuously and treat the interviewer as a collaborator—ask for hints if stuck, but show you can make progress independently. Always leave a few minutes to review your code for off-by-one errors and edge cases.
Restate the problem in your own words, ask clarifying questions about input/output, constraints, and edge cases. Confirm assumptions with the interviewer.
Describe your algorithm at a high level, including data structures and why they are appropriate. Analyze time and space complexity.
Write clean, well-structured code with meaningful variable names. Modularize if helpful, and handle edge cases explicitly.
Walk through your code with a few test cases, including edge cases. Fix any bugs and verify correctness.
If time permits, discuss potential optimizations or alternative approaches. Reflect on trade-offs and scalability.
