CDC/RDC Whiteboard Framework: Interview Drills

Interview Drills for CDC/RDC Whiteboard Framework.

Interview drills

Interview Drills for CDC/RDC Whiteboard Framework focuses on problem decomposition quality, mechanism-first answer quality. The goal is to convert issue observations into mechanism-backed closure decisions.

PROMPT
You see problem decomposition quality, mechanism-first answer quality in CDC/RDC Whiteboard Framework. Explain root cause and signoff decision.

STRONG ANSWER
1. Names crossing/reset class and context.
2. Explains Strong interview answers trace crossing intent, failure mechanism, containment strategy, and signoff evidence in a deterministic sequence.
3. Requests whiteboard template, interview rubric, sample answers.
4. Chooses fix/waiver/escalation with regression plan.

WEAK ANSWER
Lists tool commands or generic advice without mechanism and risk framing.

Mini case study

Candidate gave command-heavy answer but missed risk framing and waiver governance.

Debug branches

Use mechanism-first structure
name ownership and evidence
close with signoff decision

Senior review question

Ask: what evidence proves this risk is closed for silicon, not just tool-clean?

Key takeaways

State crossing class, assumptions, and owner with every issue.
Run structural and dynamic regressions after each fix.

Common pitfalls

Treating all warnings as equivalent risk.
Waiving issues without containment evidence.
Skipping reset and reconvergence stress after CDC fixes.
