See how your candidates
actually think.

CollabSignal gives engineers real tools and real AI, then shows you exactly how they use them. No more guessing.

Traditional platforms

Ban AI. Test memorization. Return a pass/fail score.

CollabSignal

Embrace AI. Observe behavior. Deliver a complete profile.

What we measure that no one else can.

Prompt Engineering

How specific and contextual are their AI requests? We analyze every payload.

65% Human 35% AI

Code Ownership

What percentage of the final code was written vs AI-generated vs modified?

WriteTestFixTest

Verification Discipline

Do they test continuously or only at the end? The cadence reveals everything.

Architectural Thinking

Do they read the codebase first? Do they understand the system before changing it?

Iteration Speed

How quickly do they move through prompt → edit → test → refine cycles?

AI Calibration

The best engineers know when to use AI and when to code manually. We measure that balance.

Three steps. Zero overhead.
