Voice mode with live transcription simulates real screens; use it when you can speak aloud. Text mode works in shared or silent spaces—answers still flow into the same scoring pipeline.

Optional recording lets you replay pacing and filler words after the session report loads.

Clarify constraints, describe approach, then implementation and complexity. Mention trade-offs (cache vs fresh data, SQL vs NoSQL) even for take-home-style talking points.

ZelX scores by skill areas—rambling without structure often shows up as weak communication scores even when technical content is partially correct.

Use situation → task → action → result. Tie examples to projects listed on your ZelX resume so stories stay verifiable.
