Same problems, different evaluation criteria.
Communication: You're expected to drive. State your approach before coding. Explain trade-offs proactively.
Production thinking: Mention error handling, testing, and edge cases without being asked.
Optimization dialogue: After solving, discuss improvements. Time vs space. What if input scaled times?
Composure: Interviewers watch how you handle being stuck. Panic fails. Systematic debugging passes.
The goal isn't "fastest solution." It's "would I trust this person in a production incident?"
