How should you communicate during a live coding interview?

Short answer: Clarify inputs/outputs/constraints first. Propose brute force, then optimize. Speak while coding, test with an example, and state complexity. Silence is riskier than imperfect code with clear thinking.

Interview approach

1. Restate the problem in one sentence.
2. Ask about constraints, duplicates, nulls, and expected complexity.
3. Outline approaches and pick one with justification.
4. Code incrementally; verify with a dry run.
5. Discuss trade-offs and follow-ups even if time ends.

Mistakes to avoid

• Jumping into code silently
• Ignoring edge cases
• Optimizing prematurely without a correct baseline

Interviewers hire teammates — communication is part of the score.
