16. Final Tips

Interview best practices: explain simply, cover trade-offs, and test edge cases.

• Define first, then example, then trade-offs; stay concise.
• Prefer clear names and simple control flow over clever tricks.
• Mention time/space complexity when it matters.
• Choose concurrency tools by workload: I/O → threads/async; CPU → processes.
• Use context managers and targeted try/except; avoid bare except.
• Validate inputs and cover edge cases (empty, None, large values) in tests.
• Read error messages fully; they often tell you the fix.
• Think aloud in interviews; narrate assumptions and decisions.
