Interview preparation that compounds
Make the hard part familiar.
Rehearse real interview loops, study what you missed, and carry the context into every application.

An interview loop, not a prompt box.
The interviewer pushes your reasoning, unlocks the editor, and reviews the code while the clock keeps moving.
One loop. Every rep compounds.
What you study shapes the interview. What happens in the interview shapes what you practice next.
