What problem does it solve?
You are hiring senior engineers alone and every interview feels ad hoc with incomparable notes and no clear system-design bar.
Who is it for?
Founders or tech leads running their first structured senior loop with system design as a core bar.
Skip if: Builders who only need leetcode drills with zero hiring process or teams with a full HRIS already owning rubrics.
When should I use this skill?
User wants to design, document, or score system-design interviews and hiring loops.
What do I get? / Deliverables
You get a repeatable interview system with dimension scores, multi-interviewer records, and explicit hire recommendations your agent can extend into hiring plans.
- Interview rubric structure
- Normalized score records per interviewer

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is validate because the skill supports proving you can hire the right help before a big build commitment. Interview system design is scoping who you need and how you evaluate fit—not shipping product code.
Where it fits
Define competency weights before posting your first senior backend role.
Align system-design questions with the architecture you are actually shipping.
Compare interviewer scores on the same candidate_id to reduce drift after your second hire.
How it compares
Use for interview-system design and scoring templates—not for automated code execution or production monitoring.
Common Questions / FAQ
Who is interview-system-designer for?
Solo and indie technical founders who must design fair, repeatable senior interviews—especially system design—without a recruiting department.
When should I use interview-system-designer?
In validate when scoping your first hire; in build/pm when defining engineering competencies; in grow when calibrating interviewers after team expansion.
Is interview-system-designer safe to install?
Treat example datasets as sensitive if you mirror real candidates; review the Security Audits panel on this page and avoid pasting PII into shared agent logs.
