BetterSignalHQ · Signal Recovery Engine
A 6-stage adversarial engine designed to identify the 10x architect and expose the "Paper Senior" before your team wastes a single hour.
The Signal Recovery Engine
01 · Intent Verification (motivation & fit)
02 · Ecosystem Intelligence (recent shifts)
03 · GitHub Trajectory (growth & quality)
04 · Claim-to-Signal (resume vs reality)
05 · Requirement Alignment (spec clarity)
06 · Logical Drift (interview probes)
07 · Hidden Invariants (system risk)
08 · Token Efficiency (AI leverage)
09 · Humanity Signature (behavioral trace)
10 · 2x Logic Replay (final review)
Stage 1 · Intent
We filter for high-motivation, company-specific intent before we touch code. The engine looks for how precisely the candidate understands your domain, why they want this role, and whether they've done real homework on your stack and constraints.
Company Context
references roadmap & risks
Preparation
studied stack & product
Motivation
specific, non-generic
Stage 2 · Ecosystem
We test whether candidates are awake to the ecosystem they're building in—from React 19 shifts to security incidents like Log4j to AI's impact on their tools. High-signal architects continuously integrate new constraints into their mental model of the stack.
React 19
mentions breaking changes & tradeoffs
Security
references Log4j & supply-chain risk
AI Impact
uses LLMs as tools, not crutches
Stage 3 · The Past
We bypass "Green Squares." Instead, GitHub Trajectory maps language growth, commit quality, and architectural stewardship over time. This stage can be toggled on for candidates with public work, giving you a longitudinal view of how they actually evolved.
Refactor Density
14 structural / 18 months
Stack Breadth
TS, Go, infra-as-code
Quality Trend
improving
[trajectory] languages=3 · code_reviewed=82% · anomalies=0
Stage 4 · The Resume
Resumes are now AI-hallucinated. We cross-reference every claim—from "Kubernetes Expert" to "Low-Latency Guru"—against real-time performance in our probes. We flag the Integrity Gap immediately.
Resume Claim
"SQL Expert" · "Performance Tuning"
Probe Result
Failed index-optimization + lock-contention probes
[gap] integrity_score=0.31 · recommendation=hard filter
Stage 5 · The Spec
Before any coding, we test whether candidates interrogate the spec. High-signal architects clarify ambiguous milestones, dependencies, and failure modes instead of sprinting into code that solves the wrong problem.
Clarifying Questions
milestones, SLAs, edge-cases
Assumption Calls
explicit, documented
Risk Surfaced
delivery & failure modes
Stage 6 · The Interview
We inject "Logical Drift"—a fundamental rule change in a standard problem that breaks LLM training data. AI-cheaters follow the training; Engineers follow the logic.
LLM Output
"standard solution detected"
Human Output
"constraint mismatch · re-evaluating requirement"
Drift Applied
+17%
LLM Failure
91%
Human Detection
72%
Stage 7 · The System
We present code with a hidden dependency mapped to dummy logs. A junior cleans the code and breaks the system. A Senior stops and asks: "What owns these orphaned keys?"
[09:14:03] candidate deletes "legacyMapping"
[09:14:04] ▶ invariant_breach: orphaned_log_entries_detected
[09:15:22] ▶ senior_candidate: "what owns these orphaned keys?"
Blind Refactor Score
high = risk
System Awareness
architect-level
Stage 8 · The Future
Modern 10x Engineers leverage AI as a force multiplier. We measure the "Token-to-Productivity Ratio." Can they guide an LLM to a complex fix in 2 prompts, or 20?
Prompt-to-Fix Path
[Complexity: High... Prompts: 2... Token Efficiency: 98th Percentile]
Stage 9 · The Behavior
We analyze non-linear coding telemetry. Real developers delete, pause, and refactor. LLMs dump perfect blocks of code. Our Signal Confidence Score guarantees a human brain is in control.
Undo Events
human-like
Cursor Jumps
non-linear
Burst Pattern
messy, iterative
[Keystroke Trace... Undo Events: High... Non-linear Cursor Jumps...]
Stage 10 · Final Review
We generate a high-speed filmstrip of the candidate’s entire thought process—every edit, pause, and branch—compressed into a 2x replay for your final decision review. Your team sees the real problem-solving arc, not just the end state.
// Initial problem: sort by custom rule
function sort(arr) {
return arr.sort((a, b) => a - b);
}
