Signal Layer fuses your prep depth and how your answers actually land into one readiness score. It moves as you practice, so you know when you are ready, not just hoping.
Signal Layer is the engine that keeps CaseBrick honest. It weighs how deep your prep is and how your rehearsed answers actually score, resolves them into one readiness number for this specific interview, and sets your RoleFit match beside it.
Most readiness scores only climb — which makes them meaningless. Signal Layer moves both ways: add a harder role or leave an answer weak and it drops, so it reflects where you actually stand.
Signal Layer follows every prep, not just one. See where you stand on each role side by side, so you spend your time on the interview that is closest to the offer.
RoleFit grades the page, the Delivery Engine grades the voice, and Signal Layer fuses them into readiness — one honest measure, versioned and benchmarked, that runs on your device.
